The LaRouche Youth Movement was started
around the year 2000 when the economist and statesman Lyndon LaRouche
was running a presidential campaign in the United States. The
participation of a certain group of young bright students in campaigning
for the LaRouche’s Candidacy led to the formation of the most creative
political force in the world today.
The activities of the LYM in the United States created an echo worldwide in the springing up of several similar movements throughout the world and their adoption of the same curriculum and emphasis on universal principles acting as the only true and just authority in the Universe.
It is within this Dynamic of Change that the Committee for the Republic of Canada extended itself to support the development of the LaRouche Youth Movement in Canada.
The Movement studies Science, Art and Physical-Economics to better intervene politically in our Nation with the intention and assumption that we can change the current dynamic presently destroying civilization as we speak. That is the job of every patriot, to take responsibility for all of mankind. With this in mind, it becomes absolutely necessary to eliminate the biggest threat to the survival of our civilization, namely the British Monetary System of Finance based on the tyrannical control over money. A creative system of National Credit rooted in the historical tradition that led to the adoption by the United States of America of it’s unique Constitution is needed to free mankind from the principle of Empire.
Only LaRouche’s solution aims high enough to give humanity a fighting chance at a decent future. We can’t be allowed to compromise when the opportunity to eliminate the British Empire is now, in a very real way, within reach as it has never been before.
You want to live in a dark age? We don’t think you do, but that’s exactly what’s in store for all of us, already, if we were to shy away from the necessary swiftness and boldness that is absolutely necessary today, now, to intervene with the castration of the fake debts out there with the “Glass Steagall” criteria which determines a legitimate debt from a piece of worthless gambling paper. If we can have the guts to do just that, then, a new start, a new credit system as defined by LaRouche in sundry locations, will enable the whole world to rebuild and ameliorate the physical conditions of life for everyone.
We are going to Mars! That’s the idea that can unite Mankind. With this idea in mind ask yourself what is needed to have humans living there in the next 75 years? That idea can and must serve to unite all of mankind to recognize our common aims now and into the future.
You are encouraged to see yourself as a unique sovereign personality with the potential to intervene and help us change the world. We are recruiting the population to fight for the future of Mankind.

Mind Over Mathematics: How Gauss Determined the Date of His Birth
By Bruce Director
This afternoon, I will introduce you to the mind of
Carl Friedrich Gauss, the great 19th century German mathematical
physicist, who, by all rights, would be revered by all Americans, if
they knew him. Of course, in the short time allotted, we can only
glimpse a corner of Gauss’s, great and productive mind, but even a small
glimpse, into a creative genius, by working through a discovery of
principle, gives you the opportunity to gain an insight into your own
creative potential.
I caution you in advance, some concentration will be
required over the next few minutes, in order to capture the germ of
Gauss’s creative genius. So stick with me, and you will be greatly
rewarded.
I have chosen to look into a subject, which most of
you, and even your children, think you know something about: arithmetic.
Plato, in the Seventh Book of the Republic, says that all political
leaders must study this science, because arithmetic is the science whose
true use is “simply to draw the soul towards being.” Arithmetic, Plato
says, is never rightly used, and mostly studied by amateurs, like
merchants or retail traders for the purpose of buying and selling.
Instead, political leaders, must study arithmetic, “until they see the
nature of numbers with the mind only, for their military use, and the
use of the soul itself; and because this will be the easiest way for the
soul to pass from becoming to truth and being.”
By now, you may already get the hint, that what Plato
and Gauss, meant by arithmetic, is not, the buying and selling
arithmetic, you and your children were taught in school. Gauss called
his, the “higher arithmetic,” and in 1801, he published the definitive
study into higher arithmetic, called by its Latin name, {Disquisitiones
Arithmeticae.} As you will see, if your teachers had been interested in
training true citizens of a republic, higher arithmetic, is what you
would have learned; not the amateurish calculations, needed by fast-food
cashiers, stock-brokers, derivatives-traders, or calculating methods of
the statisticians and actuaries who determine what lives are
cost-effective, for HMO’s and insurance companies.
Unfortunately, the Enlightenment dominates the
thinking of most people today, comprising an Empire of the Mind, where
people instinctively stick to simple addition, even though a higher
ordering principle is discoverable. They labor under the illusion, that
adding the numbers one-by-one, is their only choice, simply because the
creative powers of their minds are unknown to them. It is the underlying
assumptions, of which people are not even aware, which determine their
view of the world. Only by becoming conscious of these underlying
assumptions, and then changing them, can any scientific discovery be
made.
Now let’s catch a further glimpse of Gauss’s genius,
(and a little of our own) by turning to another, more profound
application of higher arithmetic.
Humble Beginnings
Carl Friedrich Gauss, came from a very humble family.
His father, Gebhard Dietrich Gauss was a bricklayer; his mother,
Dorothea Benz, the daughter of a stonemason. She had no formal
schooling, could not write, and could scarcely read. They were married
April 25, 1776, three months before the signing of the American
Declaration of Independence. Sometime in the Spring of the next year,
Dorothea gave birth to Carl Friedrich.
Being barely literate, Gauss’s mother could not
remember the date of her first son’s birth. All that she could remember,
was that it was a Wednesday, eight days before Ascension Day, which
occurs 40 days after Easter Sunday. This was not necessarily an unusual
circumstance in those days, as most parents were preoccupied with
keeping their infant children alive. Once the struggle for life was
secured, the actual date of birth might have gone unrecorded.
Twenty-two years later, the mother’s lapse of memory,
provoked the son to employ the principles of higher arithmetic, to
measure astronomical phenomena, with a discovery grounded in the
principle that the cognitive powers of the human mind are congruent with
the ordering principles of the physical universe.
In 1799, Gauss determined the exact date of his birth
to be April 30, 1777, by developing a method for calculating the date
of Easter Sunday, for any year, past, present or future.
A lesser man, wanting to know such a bit of personal
information, would have relied on an established authority, by looking
it up in an old calendar, or some other table of astronomical events.
Not Gauss! He saw, in the riddle of his own
birth-date, an opportunity, to bring into his mind, as a unified idea,
the relationship of his own life, to the universe as a whole.
The date that Easter is celebrated, which changes
from year to year, is related to three distinct astronomical events.
Easter Sunday, falls on the first Sunday, following the first full moon
(the Paschal Moon), following the first day of Spring, (the vernal
equinox). Because of Easter’s spiritual significance, and its
relationship to these astronomical phenomena, finding a general method
for the precise calculation of the date of Easter, had long been a
matter of scientific inquiry.
Let’s look at what’s involved in the problem of
determining this date. You have the three astronomical events to account
for. First, is the year, the interval from one vernal equinox to the
next, which reflects the rotation of the earth around the sun. Second,
the phases of the moon, from new moon to full moon to new again, which
reflects the rotation of the moon around the earth; and third, is the
calendar day, which reflects the rotation of the earth on its axis.
Of course, you can only “see” these astronomical
events in your mind. No one has ever seen, with their eyes, the orbit of
the earth around the sun, or the orbit of the moon around the earth.
Not until modern space travel had anyone ever seen the rotation of the
earth on its axis. We see with our eyes, the changes, in the phases of
the moon, the changes in the position of the sun in the sky, and the
change from day to night and back to day. We see “with our minds only”,
the cause of that change. This type of knowledge is outside the
Enlightenment’s straight jacket.
Each of these astronomical phenomena is an
independent cycle of one rotation. The problem for calculation, is that,
when compared with each other, these rotations do not form a perfect
congruence (Fig. 1).
There are 365.2422 days in one year; 29.530 days in
one rotation of the moon around the earth, called a synodic month; and
12.369 synodic months in one year. These figures are also only
approximate, as the actual relations change from year to year, depending
on other astronomical phenomena.
Here we confront something, which was known to Plato,
and specifically identified by Nicholas of Cusa, in his {On Leonard
Ignorance.} There exists no perfect equality in the created world.
Perfect equality, exists only in God. But since, man is created in the
image of God, through his creative reason, man can rise above this
limitation, and see the world with his mind, ever less imperfectly, as
God sees it.
As Leibniz says in the {Monadology,} man can reflect
on God with his reason only; and “we recognize, what is limited in us,
is limitless in Him.”
So if there is no equality in the created world, we
need a different concept. Our mathematics must be concerned with some
other relationship than equality, if we are to successfully measure the
created world.
A New Type of Mathematics
Gauss did this by inventing an entirely new type of
mathematics. A mathematics, which reflected the creative process of his
own mind. If the mathematics accurately reflects the workings of the
mind, it will accurately reflect the workings of the created world, as
any Christian Platonist would know.
This is real mathematics, not the Enlightenment’s
dead mathematics of Leonhard Euler and today’s illiterate computer
nerds, like Bill Gates, who think a computer is the same as the human
mind. Their mathematics is no more than a system of rules to be obeyed.
The Enlightenment imposes a false separation between the spiritual and
physical realms. If the physical world doesn’t conform to the
mathematics, the Enlightenment decrees, there is something wrong with
the physical world, not the mathematics! And, if the creative mind
rebels against the dead mathematics of Euler and Gates? The
Enlightenment demands that the mind {submit} to the tyranny of
mathematics.
Gauss’s higher arithmetic begins with a concept
different from simple equality. The concept of “congruence.” Here again,
you see how you and your children have been lied to by your teachers.
Most of you have been taught, that congruence is the same as equality,
when applied to geometrical figures, such as equal triangles. Not true.
Gauss’s concept of congruence, follows the concept of
congruence developed by Johannes Kepler, in the second book of the
{Harmonies of the World.} The word congruence, Kepler says, means to
Latin speakers, what harmonia, means to Greek speakers. In fact the word
harmonia, and arithmetic, both come from the same Greek root. Instead
of equality, congruence means harmonic relations.
Here are some examples of what Kepler means by
congruence (Fig. 2). As you imagine, in the plane, I can increase the
size and number of sides, of each polygon, without bound. But, when I
try to fit polygons together, with one another, I bump into a boundary.
Triangles, squares, and hexagons are perfectly congruent. Pentagons, for
example, are not (Fig. 3). In some cases, when I mix polygons together,
such as octagons and squares, I can make a mixed congruence.
However, when I go from two to three dimensions, and
try to form a solid angle, the boundary conditions for congruence
change. For example, pentagons, which aren’t congruent in a plane, are
congruent in a solid angle (Fig. 4). Hexagons, which are congruent in a
plane, are not congruent in a solid angle.
So you see, the type of congruences which can be
formed from polygons, is dependent on the domain, in which the action is
taking place.
Gauss carried this concept of congruence over into
arithmetic, using whole numbers alone. Two whole numbers are said to be
congruent, relative to a third whole number, if the difference between
them is divisible by that third number. The third number is called the
modulus (Fig. 5). Gauss designated the symbol {@id} to distinguish
congruence from equality ({=}).
You may recognize a similarity between the concept of
congruence with the idea of musical intervals. In higher arithmetic, it
is the interval between two numbers, and relationship between those
intervals, which concern us. Just as in music, it is the intervals, and
the relationship between the intervals, which communicates the musical
ideas, not the notes themselves.
Another property of congruent numbers, is that they
leave the same remainder when divided by the modulus (Fig. 6). These
remainders are called least positive residues. For example, 16 and 11
are both congruent to 1 modulo 5. In higher arithmetic, numbers are
related, not by their equality, but by their similarity of difference,
with respect to a given modulus.
There are other important relationships among
congruent numbers. For example, if two numbers are congruent relative to
a given modulus, they will be congruent to a modulus which divides that
modulus. For example, if 1,997 is congruent to 1,941 modulo 28, they
will also be congruent, relative to modulus 4 and modulus 7, as 4 X 7 =
28 (Fig. 7).
Here we are ordering the numbers, not according to
their “natural” given order, but according to a mental concept of
congruence. In this way, we make the numbers work for our mind, not
enslave our minds, to the order of the numbers.
Calculating the date of Easter
For purposes of our present problem, calculating the
date of Easter Sunday for any year, you can think of the astronomical
cycle as the modulus. The day, the year, and the synodic month, are all
different moduli. The scientific question to solve, is, how can these
three moduli, be made congruent?
If this weren’t hard enough, we still have another
problem: the imperfection of human knowledge. This reflects itself in
the problem of the calendar.
In 45 B.C., Julius Caesar, decreed the use of a
calendar throughout the Roman Empire, that approximated the length of
the year as 365 and 1/4 days. The 1/4 day, was accounted for, by adding
one day to the year, every fourth year, the familiar “leap year.” In the
language of Gauss’s higher arithmetic, the years are in a cycle of
congruences relative to modulus 4. Those years, which leave no remainder
when divisible by 4, are leap years; those that leave a remainder of 1
are 1 year after a leap year, and so forth (Fig. 8).
However, as we have seen, the length of the year is
not exactly 365 1/4 days. It’s a little bit shorter. This difference, is
not very significant, in the span of one human life, but is significant
over centuries, and millennia. In fact, the Julian calendar is off by
{one day,} every 128 years. Such a difference may not concern you, if
your mind is narrowly focused on your own physical existence. It {will}
concern you, if you’re thinking of your own life with respect to
posterity.
By 1582, the Julian calendar was off by ten days. The
vernal equinox, the first day of Spring, was occurring on March 10th or
11th instead of March 21. Easter, therefore was also occurring earlier
in the year. Both the material and spiritual world, had gotten out of
whack.
So, in 1582, Pope Gregory XIII, put a new calendar
into effect; ten days were dropped out of that year. In addition, the
leap year skipped three out of four century years, and every fourth
century year, would be a leap year; for example, the year 2000 will be a
leap year, but 1900, 1800, and 1700, were not.
Thus, in order to calculate Easter Sunday, and thus
determine his own birthday, Gauss had to make congruent, three
astronomical phenomena, and two imperfect states of human knowledge!
He accomplished this by reference to two other
cycles, or moduli. Because the synodic month and the calendar year, are
unequal, the phases of the moon occur on different calendar days, from
year to year. But every 19 years, the cycle repeats. So, for example, if
the Paschal Moon occurs on say, March 23, in one year, it will occur on
March 23, 19 years later. If the Paschal Moon occurs on April 11, the
next year, it will occur on April 11, again in 19 years.
If we call the first year in this cycle “year 0,” the
next year, “year 1,” the last year will be “year 18.” In this way, the
calendar years in which the phases of the moon coincide, will be
congruent to each other relative to modulus 19. So, if you divide the
year by 19, those years with the same remainder, will have the same
dates for the phases of the moon.
The calendar days on which the days of the week
occur, also change from year to year. Today is Sunday, February 16. Next
year February 16, will be on a Monday. Since there are seven days of
the week, this cycle would repeat every seven years, but because every
four years is a leap year, this cycle repeats itself, only every four x
seven, or 28 years.
However, in the Gregorian calendar, this cycle is thrown off, by the century years. This cycle is called the solar cycle.
Gauss’s Algorithm
Prior to Gauss’s discovery, a complicated series of
tables, was compiled from these cycles, by which one could determine the
date of a specific astronomical occurrence. Gauss’s genius was to find a
simple algorithm, by means of higher arithmetic, which didn’t require
any tables, but simply the number of the year. I will illustrate it for
you by example (Fig. 9)
Take the number of the year, divide by 19, call the
remainder {a.} For 1997, a=2. In the language of higher arithmetic, 1997
is congruent to two, modulo 19. This tells you where, in the 19-year
cycle of the phases of the moon, and the calendar day, the year 1997
falls.
Divide the year by four. Call the remainder {b.} For
1997, b=1. 1997 is congruent to one, modulo four. This tells you the
relationship with the leap year cycle.
Divide the year by seven. Call the remainder {c.} For
1997, c=2. 1997 is congruent to two, modulo seven. This tells you the
relationship between the calendar day, and the day of the week.
The next step is a little more complicated (Fig. 10):
Divide (19a + M=24) by 30; call the remainder {d.} For 1997, d=2. This
gives you the number of days, after the vernal equinox, that the Paschal
Moon will appear. M changes from century to century, and is calculated
from the cycle of dates on which the Paschal Moon occurs, in that
century. For the 18th and 19th century, M=23. For the 20th century M=24.
Finally, divide (2b + 4c + 6d + N=5) by seven and
call the remainder {e.} For 1997, e=6. This gives you the number of days
from the Paschal Moon, to the next Sunday. This formula takes into
account the relationship of the year to the solar cycle. N also changes
from century to century and is based on the cycle of the days of the
week on which the Paschal Moon occurs in that century. Sunday being 0,
Monday being 1, Saturday being 6. For the twentieth century, N=5.
Gauss calculated the values of M and N into the 25th
century, and derived a general method for calculating these values for
any century. Unlike some people today, Gauss, was not planning on the
“end times.”
Therefore, Easter Sunday is March 22 + d + e. For 1997 that is March 22 + 2 + 6 or March 30, 1997 (Fig. 11).
Gauss’s method, obviously has applications, far
beyond the determination of his birthday, or the date of Easter Sunday,
for any year. In his later work, Gauss brought even more complex
astronomical observations into congruence, by use of these same powers
of the mind. But, this little example gives you a sense of how a
universal creative mind can take any problem, and see in it an
opportunity to extend human knowledge beyond all previous bounds.
Of course, we too can learn a lesson from this. The
next time a child asks you a question about how the world works,
something like, “why does the moon change from day to day?” or, “why
does the sun change its place during the day and over the course of the
year?,” don’t tell that child to look up the answer in a book, or log
onto the Internet. Help that child to discover how, as Plato says, to
see the nature of numbers with the mind only.
Then, take that child, with this newly acquired
discovery, outside and show him the night sky. Then, that child will be
able to see, in that night sky, the image of the workings of his or own
mind, and to see also, reflected back, in that image, an imperfect, yet
faithful, image of the Creator, Himself.
Plato’s {Meno} Dialogue
Can You Solve This Paradox?
By Sylvia Brewda
Plato’s dialogue the “Meno” has been one of the
documents most cited, of the anti-Aristotelian faction throughout
history, and is thus a most appropriate benchmark for the offensive
against Eulerian, linear thinking in ourselves. In a crucial section, a
young, uneducated slave-boy is guided by Socrates, from wrong opinion,
to awareness of his own ignorance, to the {knowledge} of how to
construct a square with exactly twice the area of a given square.
First, Socrates shows the slave-boy that his
immediate, naive presumption, that a square with area equal to 8 can be
constructed from one of area equal to 4 by simply doubling the lengths
of the sides, from 2 to 4, is wrong. Then, the boy is shown that his
guess of sides equal to 3 will not work either.
Socrates comments to his chief interlocutor in the
dialogue, “Observe, Meno, the stage he has reached on the path” of
coming to know.
“At the beginning he did not know the side of the
square of eight feet. Nor indeed does he know it now, but then he
thought he knew it, and answered boldly, as was appropriate–he felt no
perplexity. Now, however, he does feel perplexed. Not only does he not
know the answer, he doesn’t even think he knows…. Isn’t he in a better
position now in relation to what he didn’t know?
“…|Now notice what, starting from this state of perplexity, he will discover by seeking the truth in company with me….”
Starting at that point, with nothing more than stick
drawings in the sand, how can you show that this boy could {knowingly}
succeed in constructing the required square? What are the {Analysis
Situs} implications of this?
{Figure 1.} Here we see the original square of area
equal to 4, and the method of producing a square double in area (square
BUWD).
{Figure 2.} The construction undertaken here points
to a simple geometric proof of the Pythagorean Theorem (which says that
the square on the hypotenuse of any right triangle is equal to the sum
of the squares on the other two sides, or legs.)
{Figure 3.} Fig. 3(a) shows that in a right triangle
in which both legs are equal to {a}–that is, an isoceles right
triangle–the area of the right triangle equals one-half of the area of
the square whose side is {a.}
Figure 3(b) shows that, in a right triangle with legs
of different lengths ({a} and {b}), the area of the right triangle
equals one-half the area of the rectangle whose sides are {a} and {b.}
Look for the following autosorts in this article:
@s for superscripts
@ts for multi signs
? for square root signs
Also, in the use of a and b to denote sides of
triangles & squares, I have marked those boldface {}, because I
don’t want them to be confused with, e.g., Fig. 2(b), or something. They
don’t have to be bf, but they do have to be somehow set apart.

How Socrates Resolves the Paradox
CAN YOU SOLVE THIS PARADOX?
by Sylvia Brewda
Here we reprint the first part of this column, which
appeared in the last issue of New Federalist (No. 14, April 14, p. 12),
along with the second, concluding part, in which Socrates resolves the
paradox.
Plato’s dialogue the “Meno” has been one of the
documents most cited, of the anti-Aristotelian faction throughout
history, and is thus a most appropriate benchmark for the offensive
against Eulerian, linear thinking in ourselves. In a crucial section, a
young, uneducated slave-boy is guided by Socrates, from wrong opinion,
to awareness of his own ignorance, to the {knowledge} of how to
construct a square with exactly twice the area of a given square.
First, Socrates shows the slave-boy that his
immediate, naive presumption, that a square with area equal to 8 can be
constructed from one of area equal to 4 by simply doubling the lengths
of the sides, from 2 to 4, is wrong. Then, the boy is shown that his
guess of sides equal to 3 will not work either.
Socrates comments to his chief interlocutor in the
dialogue, “Observe, Meno, the stage he has reached on the path” of
coming to know.
“At the beginning he did not know the side of the
square of eight feet. Nor indeed does he know it now, but then he
thought he knew it, and answered boldly, as was appropriate–he felt no
perplexity. Now, however, he does feel perplexed. Not only does he not
know the answer, he doesn’t even think he knows…. Isn’t he in a better
position now in relation to what he didn’t know?
“…|Now notice what, starting from this state of perplexity, he will discover by seeking the truth in company with me….”
Starting at that point, with nothing more than stick
drawings in the sand, how can you show that this boy could {knowingly}
succeed in constructing the required square? What are the {Analysis
Situs} implications of this?
To lead the boy to discover how to construct a square
with an area twice that of the original one, Socrates draws three
additional squares, each equal to the original one. He has labelled the
corners of the original square, ABCD, and draws two new squares: BCUT;
CDXW; and, finally, “to fill up the corner here,” CUYW (see Fig. 1).
Thus, he has again drawn a square four times larger than the original
one.
Then he draws one diagonal in each of the four small
squares: BD, DW, WU, and UB. These diagonals form a new square, inside
the larger one, and, rotated half a turn with respect to it. It is clear
to the boy that, these diagonals divide each of the small squares in
half. Therefore, he can see that the area inside the new square made
from the diagonals is half that of the large square, since it contains
half of each of its component squares.
And thus, the new square, with the diagonal of the first as its side, is {known} to have twice the area of the first.
Clearly, this discovery has been made without the use
of any asserted authority. Instead, it is the innate characteristic of
the human mind, its own {Analysis Situs,} that allowed it to know the
truth of what has been drawn out of it by the Socratic method employed.
This is the power of this brief section of the “Meno”
dialogue; this is the reason why constructive geometry is of such
importance in true education. Johannes Kepler, the great Renaissance
scientist, wrote about this passage in his great work,
<cf2>“Harmonice Mundi”<cf1> (“Harmonies of the World”):
“And, indeed, this was Plato’s judgment concerning
mathematical things: that the {human mind} is, from itself, fully
informed about all, species or figures, axioms, and conclusions about
these things; truly, when the mind seems to be instructed, this
[process] is nothing other than to be reminded by diagrams, which can be
grasped by the senses, of those things which the mind must know through
itself. This he represents with singular art in the dialogues,
introducing a boy who, being questioned by a teacher, answers everything
that is asked.”
Another construction can be generated which solves
the problem, and also points to a simple geometric proof of the famous
Pythagorean Theorem–namely, that the square on the hypotenuse of {any}
triangle containing a right angle is equal to the sum of the squares on
the other two sides (the hypotenuse is the side of a right triangle
opposite the right angle).
In this construction, a square of side {a} is first
cut by diagonals, forming four equal triangles on the four sides. Then,
an equal square is constructed on each of the sides of the first square,
and each of these new squares is also divided by its diagonals into
four equal parts [see Fig. 2(a)]. Next, erase from the sand the three
triangular parts of each of these new squares whose bases do not
correspond with those of the original square [see Fig. 2(b)]. Now, a new
square is seen, one which is made up of the original square plus the
four remaining triangles outside that original square, each of which
equals one-quarter of the original. That is:
4|@ts|[{a}@s2/4]|+|{a}@s2|=|2{a}@s2
What is the length of the side of this new square?
Each side is made up of two parts, each equal to half the diagonal of
the original square. Let us call this part {b.} The sides of the outer
square are equal to the diagonal of the original one, that is, 2{b.}
Consider the four right triangles which are made by
the diagonals meeting inside the original square, {a}@s2. Each has legs
equal to {b} and hypotenuse equal to {a} [one is shown as the shaded
area in Fig. 2(c)]. The construction has already generated the squares
on the legs of each such triangle [a pair are shown marked by hatching
in Fig. 2(c)]. For each pair of such squares, the triangular sections
left outside the original square correspond exactly to the area within
it left uncovered by those sections of the same small squares which are
inside it. Thus, the area of the original square, whose side is the
diagonal of the small square, is twice that of each small square, or the
sum of the squares on the legs of the small right triangle.
However, this construction also leads us further. We
can see from Fig. 3 that the area of any right triangle is equal to
one-half the product of the two legs. Here, in our construction, this
means that the areas of the small triangles are each = ({b}|@ts|{b})/2,
and the area of the original square is equal to four of these. That is:
{a}@s2|=|4|@ts|({b}@s2/2)|=|2|@ts|{b}@s2
From this, if the symbol ?{a}@s2 indicates the side
of a square of area {a}@s2, clearly {a,} the side of the original
square, can be denoted as:
{a}|=|?(2|@ts|{b}@s2)|=|{b}|@ts|@sr(2)
In future articles, we will discover that this
relationship means that the two magnitudes, {a} and {b,} are of two
completely different types, such that neither can be measured by the
other.
The last construction, plus the material presented up
to this point, provides the basis for a geometric proof of the
Pythagorean Theorem. The starting point is consideration of the effect
of changing the lengths of the legs of the small triangles, both on the
angles of such triangles, and on the geometry of their fitting together.
How {do} you know that the sum of the squares on the sides of a right triangle is equal to the square on the hypotenuse?
Look for the following autosorts in this article:
@s for superscripts
@ts for multi signs
@sr for square root signs
There are also + and = signs, but I left them uncoded–no need to code.
Also, in the use of a, b, and c to denote sides of
triangles & squares, I have marked those boldface {}, because I
don’t want them to be confused with, e.g., Fig. 2(b), or something. They
don’t have to be bf, but they do have to be somehow set apart.
Thanks
CAN YOU SOLVE THIS PARADOX?
by Sylvia Brewda
As we said in last week’s column, a construction can
be generated which solves the problem of doubling the square, and also
points to a simple geometric proof of the famous Pythagorean Theorem,
which says that the square on the hypotenuse of {any} triangle
containing a right angle is equal to the sum of the squares on the other
two sides. (The hypotenuse of a right triangle is the side opposite the
right angle.)
Here, the square of side {a} is first cut by
diagonals, forming four equal triangles on the four sides. Then, an
equal square is constructed on each of the sides of the first square,
and each of these new squares is also divided by its diagonals into four
equal parts [see Fig 1(a)]. Next, erase from the sand the three
triangular parts of each of these new squares whose bases do not
correspond with those of the original square [see Fig. 1(b)]. Now a new
square is seen, which is made up of the original one plus the four
remaining triangles outside it, each of which equals one-quarter of the
original. That is:
4|@ts|{[a}@s2/4]|+|{a}@s2|=|2{a}@s2
What is the length of the side of this new square?
Each side is made up of two parts, each equal to half the diagonal of
the original square. Let us call this part {b.} The sides of the outer
square are equal to the diagonal of the original one, that is,
2|@ts|{b.}
Consider the four right triangles which are made by
the diagonals meeting inside the original square, {a}@s2. Each has legs
equal to {b} and hypotenuse equal to {a} [one is shown as the shaded
area in Fig. 1(c)]. The construction has already generated the squares
on the legs of each such triangle [(a pair are shown hatched in Fig.
1(c)].
This construction provides the basis for a geometric
proof of the Pythagorean Theorem. The starting point is consideration of
the effects of changing the lengths of the legs of the small triangles,
on both the angles of such triangles, and on the geometry of their
fitting together inside the square.
– * * * * –
There are many proofs of the famous Pythagorean
Theorem, but the following requires no further information than the
evident fact that any right triangle can be considered as half a
rectangle, constructed with sides equal to the legs of the triangle and
cut along one diagonal. From this construction, it is clear that the two
angles in each such triangle which are not right angles must fit
together to form one right angle, since they can be generated by cutting
the right angles in the corners of the rectangle.
To start, consider the figure of the square we just
constructed [see Fig. 1(b)]. Clearly, this is a square whose side is the
hypotenuse of the right triangle created by the intersection of its
diagonals, and the square contains four of these triangles. What changes
if these four right triangles with {equal} legs, are replaced by,
again, four copies of the particular right triangle we are
investigating, but now it is a triangle with legs of different lengths,
{a} and {b,} and hypotenuse of length {c?} The square is still the
square on the hypotenuse of this particular triangle, but now the copies
have to be placed so that each corner of the square is filled by the
meeting of the two different acute angles, to equal a right angle. That
means that the triangles have to be placed with the short leg of one
coinciding with part of the longer leg of the next [see Fig. 2(a)].
Each of these four right triangles is also half of a
rectangle, and when the rectangles are drawn in, a new square is created
outside the first, with each side equal to the sum of the sides of the
rectangle, or the legs of the triangle, {a}|+|{b} [see Fig. 2(b)]. From
this we can see that {c}@s2, the square on the hypotenuse, is equal to
the square on the sum of the legs, {(a}|+|{b)}@s2, less the four
triangular sections of the rectangles which are outside the square on
{c,} each of which is equal to the triangle we started with. These four
triangles are each half of a rectangle with sides {a} and {b,} and thus
add up to two such rectangles. This can be denoted as:
{c}@s2|=|{(a}|+|{b)}@s2|@ms|2|@ts|{(a}|@ts|{b)}
Now, we must investigate the size of the square on
{(a}|+|{b),} that is with a side made by adding the two, unequal, legs
of the triangle. It can be divided to include one square with side {a}
and, in the diagonally opposite corner, another with side {b} (see Fig.
3). Since the side of the large square is {(a}|+|{b),} the area that
remains is that of two rectangles, each with sides {a} and {b.}
Therefore, the square on {(a}|+|{b)} is equal to sum of the squares on
{a} and on {b,} plus these two rectangles:
{(a}|+|{b)}@s2|=|{a}@s2|+|{b}@s2|+|2|@ts|{(a}|@ts|{b)}
Thus, these two rectangles are equal to {both,} the
difference between the square on {(a}|+|{b)} and the square on {c, and},
the difference between that same square on {(a}|+|{b)} and the sum of
the two squares, on {a} and on {b.}
{(a}|+|{b)}@s2|=|{c}@s2|+|2|@ts|{(a}|@ts|{b)}
{(a}|+|{b)}@s2|=|{a}@s2|+|{b}@s2|+|2|@ts|{(a}|@ts|{b)}
We now {know} that the square on the hypotenuse, {c,}
of any right triangle, is equal to the squares on the two legs, {a} and
{b:}
{c}@s2|=|{a}@s2|+|{b}@s2
Further, the hypotenuse, {c,} will be equal to the
side of the square which is the sum of the squares on the two legs, or,
if we use the symbol @sr{c}@s2 for the side of the square with area
{c}@s2, we can write:
{c}|=|@sr{(a}@s2|+|{b}@s2)
Simple? Yes, but necessary. Only when this basic
theorem of the relation between two independent directions of action has
been established on a solid basis, can we develop the experimental
aspect of scientific progress, the process of measuring the effects of
an additional dimension. Now, secure in the knowledge of this simple
relationship, we can begin to measure the universe.
Measurement and Divisibility
By Bruce Director
In 1818, Karl F. Gauss accepted the assignment to
conduct a geodesic survey of a large part of the Kingdom of Hannover,
or, in other words, to measure a section of the surface of the Earth.
The project involved many difficulties, and requires, first, that one
reflect on the general concept of measurement.
Gauss’ friend and collaborator, the astronomer
Bessel, thought a man with Gauss’ mathematical ability, should not be
involved in such a practical project, to which Gauss replied:
“All the measurements in the world are not worth
{one} theorem by which the science of eternal truths is genuinely
advanced. However, you are not to judge on the absolute, but rather on
the relative value. Such a value is without doubt possessed by the
measurements by which my triangle system is to be connected with that of
Krayenhoff, and thereby with the French and the English. However low
you estimate this work, in my eyes it is higher than those occupations
which are interrupted by it. … you will agree with me, that, when one
does without all real help in numerous petty affairs, the feeling of
losing one’s time can only be removed when one is conscious of pursuing a
{great important} purpose…
“What do I have for such work, on which I myself, could place a higher value, except {fleeting hours of leisure?…”
How can you measure the surface of the Earth? Don’t
even think about using a yardstick. First think what it means to
measure. You cannot measure one thing by another, unless you first can
determine, if the two things are commensurable. If you worked through
the last several weeks’ pedagogical discussions, you know it is not
always self-evident, whether two magnitudes are commensurable with each
other.
To get a sense of this, look at a similar problem,
investigated by Euclid, Archimedes, Cusa and Kepler, about which much
commentary has already been written: Measuring the circumference of the
circle.
One can measure a circle by another circle, or a part
of a circle, but not by a line, or any other curve. A whole circle can
measure another whole circle, only with respect to size, i.e., one
circle is either greater or less than the circle by which it is
measured. But, to measure along the circumference of the circle, the
circle must be divided. The circumference can then be measured by the
divided parts.
The first and most obvious division, is by half. This
creates two semi-circles and a straight line diameter. Archimedes
thought, that, by dividing the diameter into small parts, one could
measure the circumference of the circle, but, Cusa proved, [and if you
worked through last week’s pedagogical, you would have proved to
yourself], that the diameter and circle are incommensurable. One cannot
measure the other. So in order to measure the circle, we must divide the
circumference itself into smaller parts.
Well, if we continue folding the circle in half and
in half again, we will divide the circumference into smaller and smaller
parts. The number of parts, will be powers of 2. (That is, 2, 4, 8, 16,
….) But other types of divisions must be discovered, if we want to
measure a part of the circumference which is not a power of two.
If we unfold the circle, after folding it into
quarters, we will have constructed, two diameters, which meet at the
center of the circle. Now fold the circle, so a point on the
circumference touches the center. This will form a new line, shorter
than the diameter, which intersects the circumference in two points.
Once this fold is made, it is easy to find two other folds which will
also meet at the center, forming two more lines, which will make a
triangle. (It is easier for you to discover this by experiment, than for
me to describe it without the use of diagrams.) This divides the circle
in three parts.
By a more complicated process, the circumference of
the circle can be divided into five parts, the description of which,
would require a digression here, but will be discussed in future
briefings.
It was long assumed, and Kepler proved, that it were
impossible to divide the circle into seven parts. Until Gauss, it was
believed, that this was the ultimate boundary of the divisibility of the
circumference of the circle. Gauss discovered the divisibility of the
circle into 17 parts, and other divisions also. But for purposes of
today’s discussion, what is important, is, that the process of division
has a boundary. Not all divisions are possible, and since division is
necessary for measurement, to measure requires one to discover, and if
possible, overcome these boundaries.
To conduct his geodesic survey, Gauss had to
determine how to divide the surface of the Earth, which presented many
similar problems, albeit more complex, to our above example. For
example, instead of measuring a curve, Gauss had to measure an area.
This area, was on a curved surface, which in first approximation is a
sphere, but is actually closer to an ellipsoid. How are these surfaces
divided? How are these divisions, once discovered, measured on the
surface of the earth itself? These and other problems, will be discussed
in future pedagogicals.
But, while contemplating the above, it is not
unhelpful to reflect on the following statement of Gauss, excerpted from
his “Astronomical Inaugural Lecture” in which Gauss argues against the
idea of sperating so-called practical, from so-called theoretical
science:
“To judge in this way demonstrates not only how poor
we are, but also how small, narrow, and indolent our minds are; it shows
a disposition always to calculate the payoff before the work, a cold
heart and a lack of feeling for everything that is great and honors man.
One can unfortunately not deny that such a mode of thinking is not
uncommon in our age, and I am convinced that this is closely connected
with the catastrophes which have befallen many countries in recent
times; do not mistake me, I don not talk of the general lack of concern
for science, but of the source from which all this has come, of the
tendency to everywhere look out for one’s advantage and to relate
everything to one’s physical well-being, of the indifference towards
great ideas, of the aversion to any effort which derives from pure
enthusiasm: I believe that such attitudes, if they prevail, can be
decisive in catastrophes of the kind we have experienced.”
Measurement and Divisibility Part II
Last week, we investigated the measurement of the
circumfrence of the circle. What was required, was to divide the
circumference into commensurable parts. It was demonstrated, that
division by 2, and powers of 2, was possible by repeated folding and
division by 3 was possible, by folding in a different way. Division by 5
was stated as possible, and left to the reader to accomplish, and
division by 7 was stated to be impossible, and the reader was refered to
Kepler’s proof (Harmony of the World, Book 1). To the eye, the
circumference of the circle appears smooth, and everywhere the same, yet
when one tries to divide the circle, one discovers boundaries, with
each new {type} of division. Thus, the numbers 2, 3, 5, and 7 each
signify a {type} of divisibility with respect to the circumference of
the circle.
The word {type} here is used in the sense of Cantor
and LaRouche. Each {type} of division, is seperated from the other, by a
discontinuity. One cannot divide the circle into 3 parts, from the
method of division by 2 or powers of 2. One can combine division by 2
and 3 to divide the circle into 6 parts, but a new {type} of division is
required for 5 parts.
Let’s experiment with other types of divisions, with respect to other types of curves and surfaces.
Once the circle is divided, polygons can be formed by
connecting the points on the circumference, with each other, and
triangles can be formed, by connecting the vertices of the polygon, to
the center of the circle. It is easily demonstrated, that these
triangles are all equal. Thus, the relationship of all parts of the
circumference to the center are the same.
Now look at an ellipse. The ellipse differs from the
circle, in that all parts of the circumference of the ellipse have a
relationship to two points, (called foci) not one, as in the case of the
circle. Specifically, the distance from one focus, to the circumference
of the ellipse, plus the distance from the circumference to the other
focus is always the same. In the case where these two foci come
together, and become one, the ellipse becomes a circle.
Look further at the ellipse. One can fold the ellipse
in half in only two ways (which for convenience we can call horizontal
and vertical), whereas, the circle can be folded in half in an infinite
number of ways. When the ellipse is folded in half, one of the lines
generated, will be longer than the other, the intersection of these two
lines, (called axes) will be called the center of the ellipse. Two
circles can be drawn, using this center, related to this ellipse. One
will have the smaller line as its diameter, and the other will have the
longer line as its diameter. The former will be smaller than the
ellipse, the latter will be larger.
Now divide the larger circle into any possible number
of parts, and form the triangles associated with the polygon which is
formed by the division. The sides of the triangles, which correspond to
radii of the circle, will intersect the circumference of the ellipse,
dividing the circumference of the ellipse. Now connect the points of
intersection with the circumference of the ellipse, to one another,
forming triangles in the ellipse. It is easily seen, that unlike the
circle, these triangles are not equal, consequently, the divisions of
the circumference of the ellipse, formed by these divisions of the
circle, are not equal. Hence, the ellipse, cannot be divided, or
measured, in the same way as the circle. A new discontinuity has been
reached.
This new discontinuity arises from the difference in
the characteristic curvature, between the circle and the ellipse. The
curvature of the circle is constant, while the curvature of the ellipse
is always changing.
This problem, of measuring the circumference of the
ellipse, a crucial problem for physics and astronomy, was investigated
by Kepler, and further developed by Gauss, by applying his hypothesis of
the complex domain. These issues will be investigated in future
pedagogical discussions. But for now, take one more step. Now think of a
sphere. By what method, can one divide the sphere in half, and what
will this tell us about the underlying hypothesis concerning the
divisions of the circle and the ellipse?
More next week.
MEASUREMENT AND DIVISIBILITY PART III
Last week’s discussion ended with the question: By
what method can we divide a sphere in half? Let’s compare this problem,
with the problem of dividing the circle in half. This was accomplished
by folding the circle on itself, and, we discovered certain boundary
conditions, with respect to that process. How can we apply this method
to the problem of dividing a sphere?
First think about what we did when we folded the
circle. We weren’t simply dividing the circle. We were applying a
rotation to the circle, in a direction different then the rotation which
generated the circle itself. That is, a circle of 2 dimensions, is
rotated in 2 + 1 dimensions. Division in n dimensions, was effected by a
transformation in n + 1 dimensions.
Now apply this to the sphere. Obviously the sphere
can not be folded, but it can be spun. Or, in other words, if we
consider the sphere, as a surface of 2 dimensions, we must take action
in 2 + 1 dimensions, in order to divide it. So, if we pick a point on
the surface of the sphere, and, spin the sphere around that point, every
point on the sphere, except the one exactly opposite the initial point,
will move. These two points can be connected by the equivalent of the
diameter of the circle, which on the sphere is a great circle, that
divides the sphere in half.
Now apply this principle, of measuring n dimensions,
with respect to n+1 dimensions, to the initial discussion three weeks
ago about Gauss’ efforts at measuring the surface of the Earth. How do
we locate our initial position? With respect to north and south, we can
measure the angle at which we observe the North Star. The higher
overhead the North Star is, the farther north our position on the Earth.
To measure our position on the surface of the Earth, we must look up,
to the stars. This measurement is, therefore, n+1 dimensions, with
respect to the n dimensions of the surface of the Earth. Now for our
position with respect to east west, we must refer to the rotation of the
earth on its axis, which goes from east to west. We measure this, with
respect not only to a change in position with respect to heavenly
bodies, but with respect to a change in time. Another dimension,
(n+1)+1.
Once this position is determined, we now measure
other locations in a similar manner, and then measure the distance
between those locations, using triangles. In order to meaningfully
measure the surface of the Earth, these triangles must be large. Too
large to measure with rulers, yardsticks, or chains. If we start with
two relatively close points on the earth, and precisely mark off the
distance between them, we can then measure the distance between these
two points and a third point, by measuring the angles that form the
triangle between these three points. This is done, by placing an object
at each point, that can be seen, using a telescope, from the other
points, and we measure the angle at which the telescope has to be
turned, to see each point.
Gauss invented a device, called the heliotrope, that
used a small mirror to reflect sunlight, that could be seen, by a
telescope, from many miles away. If three such devices are positioned at
three different points on the Earth’s surface, a very large triangle
can be formed, that can be measured precisely. In this way, the surface
of the Earth, can be covered with a network of triangles, and measured.
But, when we look through these telescopes, to see
each point, the light is refracted (bent), by the atmosphere, and the
lens of the telescope. This makes what we see, different from the actual
position of the point on the Earth. So this physical property,
refraction of light, must be taken into account in our
measurement–another dimension, [(n+1)+1]+1.
But since our measuring points are at different
elevations, we use a level, which adjusts its position with respect to
gravity. So we must measure variations of the gravitational field of the
Earth, yet another dimension, {[(n+1)+1]+1}.
Likewise, when using a compass, which reflects
changes in the magnetic field of the Earth, we must measure variations
in the magnetic field of the Earth–yet another dimension,
{[(n+1)+1]+1}+1. And so on, with each new physical principle discovered.
The inclusion of each new dimension is not a simple
addition, but a transformation in the hypotheses underlying our
conception of physical space-time. Just as the idea of dividing a
circle, contained within it, an underlying assumption of a higher
dimension, which wasn’t apparent, until thought of in terms of dividing
the sphere, each new dimension, corresponding to a physical principle,
uncovers previously “unseen” assumptions, with respect to the hypothesis
of lower dimensions.
But, these assumptions, expressed in the form of
anomalies and paradoxes, won’t be “seen,” unless you look for them, not
in n dimensions, but in n+1 dimensions. You can’t measure where you are,
except with respect to the horizon, which cannot be “seen”, except with
respect to the higher dimensionality, which you are seeking to
discover, but which you will not find, unless you have the passion to
“look” for it.
The Importance of Good Maps
by Bruce Director
As the pedagogical series on spherical geometry has
indicated, a profound discovery arises, when you attempt to map
spherical action on to a flat plane. Any such effort, immediately
presents to the mind, the existence of two distinct types of action.
Basic investigations of the physical universe, astronomy and geodesy,
immediately confront us with the need to discover the conceptions that
underlay this discontinuity.
Already we have presented several examples of this,
which you can work through quickly in your mind before proceeding. Think
of the various examples that demonstrated that spherical nature of the
manifold of measurement of space. Think of the conception of the
Platonic Solids from the standpoint of Kepler’s re-discovery of the
Pythagorean concept of congruence (harmonia). Think how we demonstrated
that solids arise as the characteristic perfect congruences on a surface
of constant positive curvature, as distinct from the perfect
congruences that arise on a surface of zero curvature. And also, think
of the pentagramma mirificum, and emergences of two distinct
periodicities that arise from carrying out the same action, on surfaces
of two different curvatures. (All the above examples were elaborated in
pedagogical discussions published over the first three months of 1999.)
Now let’s delve into this area once again. First,
from the standpoint of mapping the stars, as represented on a surface of
constant positive curvature, onto a surface of zero curvature, a most
ancient investigation.
In our observation of the heavens, the stars are
projected onto a spherical surface, as a function of our measuring their
changing positions, as a change in the angle between the line of sight,
the horizon and some arbitrary direction perpendicular to the horizon,
such as north, or even “straight ahead.” In this way, the changes in
position of the stars, and their relationship to each other, are
represented as arcs of circles and the angles between such arcs.
However, as we’ve seen before, when we try to project
this spherical projection of the stars, onto a flat surface,
discontinuities aries. Furthermore, the nature of these discontinuities
changes depending on how we effect that projection. In other words, not
all projections from a sphere onto a plane are the same.
You can carry out a simple demonstration of this, by
drawing a series of great circle arcs, intersecting at different angles,
on a clear plastic hemisphere. (For purposes of this description, call
the circular edge of the hemisphere the equator, and the pole of this
equator the north pole.) Hold a flashlight or candle at the position
equivalent to the south pole of the sphere so that the great circle arcs
cast shadows onto a marker board. Trace the shadows. Now, move the
flashlight toward the center of the sphere, stopping at various
intervals, and tracing the shadows of the arcs at each interval. Make
one of those intervals the center of the sphere. Trace the shadows.
You will notice a change in the curvature of the
shadows, as the point of projection changes from the south pole to the
center of the sphere. At the south pole of the sphere, the shadows are
arcs of circles. As the flashlight moves toward the center, the shadows
straighten out, until at the center, the shadows are straight lines.
Now make a more precise demonstration. Draw on the
hemisphere, an equilateral spherical triangle, such as the face of the
octahedron, that has three 90 degree angles. Perform the above
projections. When the flashlight is at the south pole, trace the
shadows. Now move the flashlight to the center of the sphere, and trace
the shadows.
The tracings of the shadows from the south pole
projection are circular arcs. Measure the angle between the lines
tangent to each arc at the each vertex. Now measure the angles between
the sides of the straight line shadows projected from the center.
These are two specific projections, the first called
the stereographic, the second called central projection, that transforms
the great circle arcs on the sphere, to the plane. As you can see, each
transformation is different. In the central projection, the spherical
equilateral triangle with three 90 degree angles is transformed into a
flat equilateral triangle with three 60 degree angles. In the
stereographic projection, the spherical triangle is transformed into
three circular arcs that intersect each other in 90 degrees. So the
angular relationship between the vertices of the triangle is invariant
under the stereographic projection.
With a little bit of thought, you should be able to
figure out why that is the case. Think of the point of projection as the
apex of a cone of light. The projection on the flat surface is formed
by the intersection of a line that starts at the point of projection,
and continues through a point on the sphere, and then intersects the
marker board. If the point of projection is at the center of the sphere,
than the lines connecting the point of projection to points on a great
circle, will all be in the same plane. Consequently, the projection of
these great circle arcs will be a straight line. In this way, the center
of the sphere can be thought of as the unique singularity from which
great circles can be projected into straight lines!
Not so if the point of projection is other than the
center of the sphere. However, if the point of projection is the south
pole, the angles between the projected arcs, are the same as the angles
between the spherical arcs. This property has come to be called,
“conformal”.
Because of this angle preserving characteristic, this
projection is particularly useful for mapping stars. The written
discovery of the stereographic projection is attributed to the Greek
astronomer Hipparchus, but its actual origins are most likely quite
older. Under this projection, the entirety of the celestial sphere can
be mapped onto a flat surface.
To do this, think of a sphere with a plane
representing the horizon, going through the center of the sphere. (You
can represent a cross section of this on a flat piece of paper as a
circle with two perpendicular diameters. Call the endpoints of one of
the diameters the north and south pole. Let the other diameter represent
the horizon.) Now, draw a line that connects every point of the
“northern” hemisphere with the south pole. Those lines will intersect
the horizon and those intersections will form a stereographic
projection. The north pole will project onto the center of the sphere.
All the points of the northern hemisphere will project onto the inside
of a circle formed by the intersection of the sphere with the plane, and
all the points of the southern hemisphere will project to points
outside that circle. Where will the south pole projet to? What other
discontinuities or distortions emerge under this transformation?
YOU HAVE TO CARRY OUT THIS CONSTRUCTION IF THE ABOVE DESCRIPTION IS TO MAKE ANY SENSE TO YOU.
Over the last two millennia, the stereographic
projection has been used to map the celestial sphere onto a plane and is
the basis of the construction of the astrolabe, one of the earliest
astronomical measuring instruments. (Rick Sanders has produced an
interesting unpublished paper on the astrolabe available to those who

The stereographic projection, therefore, represents a
unique way of projecting one surface onto another, such that a certain
characteristic, is invariant under the transformation. But, this
projection is specific to the mapping of a sphere onto a plane. Can we
find, for example in the case of a geodetic survey, where we are mapping
the geoid, onto an ellipsoid, onto a sphere, onto a flat plane, a way
to perform such a series of transformation, in which a certain
characteristic, remains invariant under repeated arbitrary projections?
This formed the subject of Gauss’ famous 1822 paper
for which he won the Copenhagen prize. The paper was titled, “General
Solutions of he Problem to so Represent the Parts of One Given Surface
upon another Given Surface that the Representation shall be Similar, in
its Smallest Parts, to the Surface Represented.” In this investigation,
Gauss delved even further into the nature of non-linear curvature in the
infinitesimally small.
The Importance of Good Maps-Part II
Last week we undertook a preliminary investigation into the projection of a sphere onto a plane. Now the fun starts.
If you carried out the constructions, you would have
re- discovered, in a formal sense, certain principles whose ancient
discovery was crucial for the development of human civilization. That
discovery can be thought of in two aspects; 1) that elementary form of
action in the physical universe is curved, and 2) that curved action is
of a different “transcendental cardinality” than linear action. The
nature of that difference is revealed in the investigation, not simply
of each type of action, but by investigating transformations between
each type, i.e., the “in betweenness.” In that sense, the study of these
projections has a significance for both the development of the higher
cognitive powers of the mind, and the capacity of those powers to bring
the physical universe increasingly under its dominion.
In general, there is no transformation of a sphere
onto a plane that does not result in distortions and discontinuities,
and it is by those distortions and discontinuities that the difference
in “transcendental cardinalities” becomes apparent. But, there are a
myriad of such transformations, each of which produces different
characteristic distortions and discontinuities. (Last week, we
investigated, preliminarily, two such transformations, the gnomic and
the stereographic projection, but there are many others.) In order to
more fully grasp the nature of the difference in “transcendental
cardinalities” between the sphere and the plane, we cannot focus simply
on specific types of transformations. We must investigate the general
nature of transformations and not just between two specific types of
surfaces, such as a sphere and a plane, but between any series of
arbitrarily curved surfaces. That is, we must jump from investigating a
particular projection, to the investigation of the general principle of
projection itself. That puts us in the domain the hypergeometric. This
is the domain unique to the contributions of Gauss and the subsequent
discoveries of Riemann.
Today’s pedagogical discussion seeks to start down
the road to the re-discovery of Gauss’ and Riemann’s contributions.
There is nothing contained below that is beyond the scope of most of the
readers, but, be prepared to concentrate on the train of thought. You
will find in it an illustration, typical of Gauss, of taking a
previously discovered principle of classical Greek science, and
approaching it from a new higher standpoint, which establishes that
classical principle, as a special case of a more general concept. It is
congruent with Beethoven’s re-thinking of the significance of the Lydian
interval, in his late quartets, to establish a new conceptualization of
the domain of J.S. Bach’s well-tempered system of bel canto polyphony.
From last week’s discussion, you should have already
demonstrated to yourself, some of the characteristics of the gnomonic
and stereographic projection of the sphere onto the plane. Specifically,
the gnomonic, (projection from the center of the sphere), transforms
great circle arcs on the sphere, into straight lines on the plane.
Obviously, since the sum of the angles of all plane triangles is 180
degrees, and the sum of the angles of triangles on the sphere are always
greater than 180 degrees, angular relationships are changed under the
gnomonic projection. On the other hand, last week’s constructions
provided the basis to demonstrate, at least initially, that under the
stereographic projection, i.e., where the point of projection is a pole
of the sphere instead of the center, the angular relationships are
unchanged when projected from the sphere onto the plane. This
characteristic is obviously crucial for geodesy and astronomy, as the
relationships between stars projected onto the celestial sphere and
positions on the surface of the Earth, as these relationships are
measured as only as angular relationships. If a representation of these
spherical relationships onto a flat surface is to be of any use, the
angular relationships must be invariant under the projection.
When thinking of possible projections from the sphere
onto a plane, the gnomonic projection seems to suggest itself most
easily. For example, in the case of the celestial sphere, the point of
projection is the observer, who projects the celestial sphere the stars
along the lines of sight from the observer through the stars, to a
plane. This projection was apparently discovered by Thales, but it is
quite possible that it was known much earlier. However, because it
distorts angles, it has obvious failings for a useful map of the stars
or the Earth.
The stereographic projection is much less obvious.
Here, the point of projection, a pole, is no where in the manifold of
the observer. But, when the projection plane is the plane of the
observer, (as in last week’s example), the point of the observer is the
only point that is unchanged under projection! This and the property
that angular relationships are not changed under the projection, make
the stereographic projection suitable for astronomical uses, such as a
star chart, or astrolabe.
The experiment in last week’s discussion, for
pedagogical purposes, indicated by demonstration, but did not prove,
that angular relationships are invariant under the stereographic
projection, a characteristic called “conformal.” One can, as Hipparchus
did, prove by principles of Euclidean geometry, that this is the case.
(Such a proof is not very complicated. It relies on
properties of similar triangles. But, to describe it in this cumbersome
format would be, for the moment, distracting. So, we leave it to the
reader to carry out.)
Gauss’ standpoint was to go beyond the principles of
Euclidean geometry, by inverting the question. Instead of starting with
stereographic projection and asking, “Is it conformal?” Gauss asked.
“What is the nature of the being conformal, and under what projections
does it exist?” The former sets out to discover the existence of a
general principle in a specific case. The latter question seeks the
nature of the general principle, under which the special cases are
ordered.
Gauss’ approach is best grasped pedagogically by a
demonstration. Take the clear plastic hemisphere you used last week,
preferably with the 270 degree equilateral spherical triangle still draw
on it. Cut out four circles out of cardboard, of different sizes. For
my experiment, I made a circles with diameters, 3 1/2, 1 1/2, 1, 1/2.
(For the circle of 1/2 inch diameter I used a thumb tack.) With tape,
attach these circles to the sphere, all at the same “latitude”, so that
they are approximately tangent to the sphere at their centers.
Now, project this arrangement onto a plane. This is
most easily done, by holding the hemisphere so that the plane of the
equator is parallel to a wall or the ceiling, and use a flashlight to
project the spherical images onto the wall or ceiling.
When you hold the flashlight so that the bulb is at
the center of the hemisphere, the shadows of the spherical triangle
will, as we saw last week, be straight lines. The shadows of the tangent
disks, will be ellipses. When you pull the flashlight back to the
position of where the south pole of the sphere would be, you will see
that the shadows of the spherical triangle will be circular arcs,
intersecting at 90 degree angles, and the shadows of the tangent disks
will be almost circular.
The change in the projection of the tangent disks,
from ellipses in the gnomonic projection, to circles in the
stereographic, is a reflection of a crucial element of Gauss’ discovery.
Gauss’ first step, was to abandon the idea of the
sphere and plane being objects embedded in three dimensional Euclidean
space, and instead, he thought of each as a two dimensional surface of
different curvatures. On any two dimensional surface, the angular
relationship of 90 degrees is a singularity, consistent with Cusa’s
notion of maximum and minimum. That is, geodetic arcs, or lines that
intersect at 90 degrees are at the maximum point of divergence. Or, in
other words, any two such arcs, or lines, define two divergent
directions. Any other angle, at which geodetic arcs lines intersect, is
merely a combination of these two directions. (Gauss goes to great
lengths to point out that these two directions are arbitrary, but once
one is chosen, the other is determined.)
Now look back to the difference in the transformation
of the tangent disks in the two projections. In the gnomonic
projection, the change of those disks from circles to ellipses, is a
reflection that the gnomonic projection changes one direction in a
different way than the other. The transformation of those disks into
circles in the stereographic projection, is a reflection of how this
projection changes both directions exactly the same.
But, there is another principle at work here that you
can discover with some careful observation. If you look closely at the
tangent disks, you should notice that in the gnomonic projection, the
shadows of the disks become more elliptical, the smaller the disk. And,
in the stereographic projection, the shadows of the disks become more
circular the smaller they are.
Remember these disks are not on the sphere, but
tangent to it. Therefore, the smaller the disk, the closer to the
surface of the sphere it is. As the disks become infinitesimally small,
the characteristic change in curvature, becomes even more pronounced. In
other words, the characteristic curvature of these projections, or any
other for that matter, is reflected in every infinitesimally small area
of both surfaces. And, the smaller the area, the more true is the
reflection! Just the opposite of linearity in the small.
Do this experiment and play with this idea a while.
You are getting close to a very fundamental principle discovered by
Gauss and Riemann, which we’ll take up in the final installment of this
series next week.
The Importance of Good Maps–Part 3
I hope you had fun conducting the experiment
described at the end of the last pedagogical discussion. This week, we
will conclude this preliminary phase of pedagogical discussions on the
early development of the Gauss-Riemann theory of manifolds, with a
discussion of the general principles of Gauss’ theory of conformal
mapping. In future weeks, we can extend these investigations, using this
preliminary work as a starting point.
It is important to remember the context in which
these investigations of Gauss and Riemann occurred. The thread begins
with Cusa’s {Learned Ignorance}, and his insistence that action in the
physical universe was elementarily non-uniform. The discoveries of
Kepler on planetary orbits, and Leibniz and Huygens on dynamics, and
light, confirmed and validated what Cusa had anticipated. In each case,
the general nature of the non- uniformity of physical action, was
discovered by the manifestation of that characteristic in an
infinitesimally small interval of action.
Gauss’ geodesy is a good case in point. Between 1821
and 1827 Gauss supervised and conducted a geodetic triangulation of most
of the Kingdom of Hannover. That undertaking confronted him with a
myriad of scientific problems, that sparked a series of fundamental
discoveries about the nature of man and the physical universe.
A short review is necessary, from the standpoint of
the last several month’s pedagogical discussions on spherical action.
Think back to the question of the measurement of the positions of the
stars with respect to a position on the Earth. Those positions will
change over the course of the night, the course of the year, and the
course of the longer equinoctial cycle. The geometrical form of the
manifold of such changes, is the inside of sphere. The daily, yearly and
equinoctial changes of the stars’ position trace curves on the inside
of the sphere. Those curves can be thought of as functions of the
Earth’s motion.
Now, think of those same observations as taken from
another position on the Earth’s surface. A new set of curves will be
generated that are a function the same motion of the Earth. But, the
nature and position of those curves will be different than the curves
traced by the observations from the first position.
These two sets of curves, give rise to a new
function, that transforms the first set of curves into the second. That
function reflects the effect of the curvature of the surface of the
Earth. This function can not be visualized in the same way, as a set of
curves, as in the case of the first two functions. This new type of
function, a function of functions, is congruent with what Gauss and
Riemann would refer to as a complex function.
In this example, a complex function is discovered
that maps spherical functions into other spherical functions, which is
another way of thinking about the concept of projection. The previous
two discussions in this series, looked into types of complex functions
that project spherical functions onto a surface of zero curvature (a
plane), such as the gnomonic projection and the stereographic
projection. These two complex functions transform the same curves from
the sphere onto the plane, but in different ways.
The stereographic projection had the unique
characteristic that the angles between great circle arcs on the sphere
are not changed when projected onto the plane. This characteristic Gauss
called conformal.
In his announcement to the first treatise on Hider
Geodesy, Gauss points out that the curves conform in the infinitesimally
small. However, in the large, the projection of the great circle arcs
are magnified, the degree of magnification changes, depending on their
position with respect to the point from which the projection is made.
The experiment projecting circles tangent to the sphere, suggested in
the last pedagogical, illustrated this point, at least intuitively.
In other words, if you think of the stereographic
projection from Gauss’ standpoint, it is a special case of a complex
function. A complex function that transforms curves on a sphere to
curves on the plane, according to a law, that conforms in the
infinitesimally small.
In the course of his geodesic investigations, Gauss
was confronted with the requirement of discovering other complex
functions that transformed functions on one surface to another. Rather
than tackle each case separately, Gauss went into the matter more
deeply, discovering the general principles on which these complex
functions rested. This was the subject of his 1822 paper referred to in
previous weeks, “General Solution of the Problem to so Represent the
Parts of One Given Surface upon another Given Surface that the
Representation shall be Similar, in its Smallest Parts, to the Surface
Represented”. These investigations formed the foundation for Riemann’s
theory of complex functions.
In his paper Gauss gives an example of such a problem
from Higher Geodesy. In his geodetic survey, Gauss measured the area of
a portion of the Earth’s surface, by laying out a series of triangles
whose vertices were mutually visible. By measuring the angles between
the lines of sight between these vertices, the area of the triangle
could be computed. As this network of triangles was extended over the
Kingdom of Hannover, the entire area of the entire region could be
computed by adding up the areas of the smaller triangles in the network.
As discussed in previous weeks, the area of these
triangles is a function of the shape of the surface on which they lie.
If a spherical shape of the Earth is assumed, then the size of the
triangle is a function of the sum of the angles comprising it multiplied
by the diameter of the Earth.
Look back on our first example above. Between two
positions on the surface of the Earth, a complex function characterizes
the difference between the observed positions of the stars at those two
positions. (For purposes of this example, consider the two positions as
lying on the same meridian. Then the measurement of that complex
function can be expressed as simply the difference in the angle of
observation of the pole star between the two positions.) Based on an
assumption about the size and shape of the Earth, the distance between
the two positions along the surface of the Earth can be calculated.
The distance between those two positions can also be
calculated by a geodetic triangulation carried out over the area of the
Earth’s surface between the two positions. That distance, when compared
with the enables us to test the original assumption of a spherical shape
for the Earth. That type of measurement determined the shape of the
Earth to be closer to an rather than a perfect sphere.
This confronted geodesist with the requirement of
projecting those ellipsoidal triangles onto a sphere, conformally. Gauss
was the first one to be able to solve this, by applying his general
method of conformal projection. The method employed is analogous to
Kepler’s measurement of planetary motion in an elliptical orbit, by the
eccentric and mean anomalies, but with the use of complex functions, of
the type described above.
In future weeks we will develop pedagogical exercises
from Gauss’ examples, and then go on to a more thorough examination of
Riemann’s revolutionary extension of Gauss’ discovery.
The Poetry of Logarithms

“You have no idea how much poetry there is in a table of logarithms.” — Karl Friedrich Gauss to His Students
Developing a function for the distribution of the
prime numbers has been one of the great challenges of mathematics. An
exact solution to this problem, of how many numbers generated between 1
and any given number, N, are actually prime, has not yet been
discovered, though there is a general notion of a succession of
manifolds as determining to any solution.
One of the most stunning demonstrations of the
generation of number by an orderable succession of multiply-connected
manifolds, is Karl Friederich Gauss’ discovery of the “Prime Number
Theorem.” The wonderfully paradoxical nature of Gauss’ approach, in
contradistinction to that of Euler, is that we must move to geometries
associated with the physics of higher-order forms of curvature, such as
the non- constant curvature of catenary functions, and those forms of
physical action associated with living processes, for a first
approximation solution.
To understand the importance, and the elegance, of
this discovery, we must first investigate a class of numbers called
logarithms. Hopefully, it will all so demonstrate the inherent
differences between a “constructive” approach to the questions of the
generation of such numbers as logarithms as over, and against, the
formalisms of the textbook. I have included as an addendum at the end of
this discussion, a short rendering on the subject of logarithms,
modeled on that of a typical textbook , so the reader might more
appreciate the conceptual gulf separating the constructive approach from
that of classroom formalisms.
“It is more or less known that the scientific work of
Cusa, Pacioli, Leonardo, Kepler, Leibniz, Monge, Gauss, and Riemann,
among others, is situated within the methods of what is called synthetic
geometry, as opposed to the axiomatic- deductive methods commonly
popular among professionals today. The method of Gauss and Riemann, in
which elementary physical least action is represented by the conic form
of self-similar- spiral action, is merely a further perfection of the
synthetic method based upon circular least action, employed by Cusa,
Leonardo, Keller, and so forth. [fn. 1]
It is in this domain, physical least action
associated with the self-similar spiral characteristic of living
processes, that we search for a solution to the ordering principle
which, in fact, might generate the prime numbers. Gauss approach
involves understanding the idea behind the notion of a logarithm.
Logarithms are numbers which are intimately involved
in the algebraic representations of self-similar conic action. In
previous discussions, we saw that number measures more than just
position or quantity; number can also measure action. We discovered that
numbers in one manifold measure distinctly different qualities, than
numbers in another manifold, and that what and how you count can
sometimes leave “footprints” of a succession of higher ordered
manifolds.
All descriptions of logarithmic spiral action, and the rotational action associated with them, are of two types of projection:
1) The 3 dimensional spiral on the of cone; we
understand that each increase in the radial length of the 2 dimensional,
self-similar spiral on the plane, is a projection from the 3
dimensional manifold of the conic spiral. The projection of the line
along the side of a cone, which intersects and divides the spiral is
called “the ray” of the cone. [See {The Science of Christian Economy},
APPENDIX I]
2) The 3 dimensional helical spiral action from the
cylinder; the rotation of the three dimensional manifold of the
cylindrical spiral (helix) projects on to the two dimensional plane as a
circle. Nonetheless, some action is taking place, and that action is
represented, therefore, by a “circle of rotation”, as simple cyclical
action, i.e. we “count” the cycles of each completed, or partially,
completed cycle of rotation of the spiral.
Turn to the April 12, 2002 issue of EIR, page 16, (See
figure), “The Principle of Squaring”; review the caption associated
with that figure [“The general principle of ‘squaring’ can be carried
out on a circle. z^2 is produced from z by doubling the angle x and
squaring the distance from the center of the circle to z.”] and
construct the relevant diagonal to a unit square. The side of the square
is one, the diagonal that square equals the square root of two. Use
that diagonal, the square root of two, as the side of a new square; the
diagonal to that square, whose area 2, will also be a length equal to
two. We are generating a series of diagonals, each, in this case, a
distinct power of the square root of two. In this case, it is a spiral
which increases from 1 to 16 after the first complete rotation; 16 to 64
after the second rotation, etc. As we will soon see, each of the
successive diagonal beginning with the first square 1, is also part of a
set of “roots” of 16.
Each diagonal is 45 degrees of rotation from the
previous diagonal; this should be obvious, since the diagonal divides
the 90 degree right angle of the square in half. Therefore, each time we
create a new diagonal and a new square, in turn generating another
diagonal and another square, we generate a series diagonals, each 45
degrees apart. It should also be obvious that 45 degrees is equivalent
to 1/8 of 360 degrees of rotation or 1/8 of a completed rotation of the
spiral.
Let us now review a few fundamental elements of this
action: we can now associate, in our spiral of squares, a distinct
amount of rotation with a distinct diagonal value. In this case the
diagonal values are powers of the square root of two or some geometric
mean between these powers.
Table 1 Rotation Diagonal Value
0 1 or ?20
1/8 ?2 or ?21
2/8 2 or ?22
3/8 ?8 or ?23
4/8 4 or ?24
5/8 ?32 or ?25
6/8 8 or ?26
7/8 ?128 or ?27
8/8 16 or ?28
9/8 ?512 or ?29
10/8 32 or ?210
The diagonals of this “spiral of squares” function much like the rays [fn2] (or radii) of a logarithmic, self similar spiral. We can imagine an infinite number of self-similar spirals increasing from 1 to any number N, after one complete rotation. Each successive complete, whole rotation will then function as a power of N[table 2]:
Table 2
Rotation Power
0 N0 or 1
1 N1 or N
2 N2
3 N3
4 N4
Since each rotation of the logarithmic spiral
increases the length of the ray (or growth of the spiral) by some factor
that we can identify as the “base” of the spiral. In other words the
base of the spiral which increases from 1 to 2 in the first rotation (
and doubles each successive rotation), is identified as base 2; the base
of the spiral which increases from 1 to 3, as base 3; from 1 to 4, as
base 4;…. 1 to N, as base N, etc.. The spiral, base N, will after one
complete rotation beginning with ray length 1, generate a ray whose
length is N^1; after 2 rotations, the spiral will generate a ray whose
length is N^2; after 3 complete rotations the ray length will equal N^3,
etc.
To measure or count rotation, we now define a “unit
circle of rotation”. We can map a point of intersection with a spiral,
and a ray spiral whose length is equal to or greater than one, on to a
point on a unit circle. In this way it seems that a point on our circle
of rotation can map on to, potentially, an unlimited number of
successive points of intersection of a spiral and any given ray. But,
when we look at our circle of rotation, we are looking at the projection
of a cylindrical spiral. We can therefore “count”, as cycles or partial
cycles, the amount of rotation required to reach the point on the unit
circle which a ray maps onto the unit circle and the spiral at the same
time.
Look again at the musical spiral of the equal
tempered scale. (see figure 1, page 50, {So You wish to Learn All About
Economics}). Here, I am looking, not at successive ROTATIONS of the
spiral, but DIVISIONS, in this case one rotation of the octave or base 2
spiral.
When I divide the rotation of the spiral by half
(6/12ths), I get F# or the square root of 2.[see chart 2]. When I divide
the rotation of the spiral by 3 (4/12ths) the first division is the G#
or the cube root 2. So each successive rotation is a power of N, i.e.
N^1, N^2, N^3, etc. Each successive DIVISION represents a root of N,
i.e. ?N, 3?N, 4?N, 5?N, etc.

As we have now discovered, given any spiral base N,
we can associate a distinct amount of rotation with a distinct power or
root of N. Each successive complete rotation can be associated with a
power of N; each division or partial rotation can be associated with
some root of N, or a mean between N and another number. This distinct
amount of rotation to a point on the “circle of rotation”, which can
then be associated with a distinct rotation of a self-similar
cylindrical spiral, is the logarithm of the number generated as a ray
intersecting the spiral at a particular point.
For example, take our spiral of the squares; that
spiral is base 16. The logarithm of 16 is one, written as Logv16(16) =
1[footnote 3]. Using our table 1, we can create a short “Table of
Logarithms” for base 16. Turn once again to the April 12, 2002 issue of
EIR, pages 16 and 17; as Bruce indicates, if I double the rotation, I
square the length. Let us try various operations with the table of
logarithms below. Table of Logarithms, Base 16 Logarithms unit value of

Add the logarithm of 2 to the logarithm of 4, base
16. What is the result? (2/8 + 4/8 = 6/8 or the logarithm of 8, base
16.) If I add the logarithm of 2, base 16 to the logarithm of 4, base
16, the two ADDED rotations give my the logarithm of 8, base 16, which
is the product of 2 x 4.
Now subtract the logarithm of 4, base 16, i.e. 4/8
from the logarithm of 8, base 16, i.e. 6/8 and the remainder will be the
logarithm of 2, base 16 or 2/8. Now take any of the logarithms from our
table, base 16; add or subtract the logarithms of any number of numbers
and see if they correlate with the division or multiplication of those
same numbers. In other words: adding or subtracting the logarithms of
numbers (i.e. the amount of rotation) correlates with multiplication or
division of those numbers,
When I am looking at the number we call a logarithm, I
am actually looking at the measure of two distinct forms of action in
the complex domain of triply extended magnitudes, i.e. the cyclical
nature of helical action, with the continuous manifold of the
logarithmic spiral. Which is precisely why Gauss understood “…how much
poetry there is in a table of logarithms.” We will look at this
relationship in another way next time when we investigate why: “It’s
Really Primarily Work.”

2) The ray of a cone is a line perpendicular to the
axis of the cone, intersecting the spiral arm [It can also be
constructed as a straight line from the apex of the cone to an
intersection with the spiral. Both project onto the plane as the same
length. When we project from the 3 dimensional cone to the two
dimensions of the plane we assume that the incidental angle of the cone
is 45 ray of the cone and the axis are of equal length.
3) LogvN(N) = 1 is the equivalent of saying “the
logarithm (Log) in base N (vN) of N (N) equals 1. In the above case
we’re saying the Logarithm of 2 in base 2 is 1
ADDENDUM I: “What is a logarithm?” according to the book.
“… a logarithm is number associated with a positive
number, being the power to which a third number, called the base, must
be raised in order to obtain the given positive number.”
Presuming we understand the concept of “the power to
which a number is raised”, then a definition for “exponent” and a “base”
might be necessary at this time. An exponent “…is a symbol written
above and to the right of a mathematical expression to indicate the
operation of raising to a power. In other words, in the simple function
of 2^2 = 4, ^2 is the exponent, in the function 2^3 = 8, ^3 is the
exponent, etc. The definition of a “base” is a little more complicated.
When we write our numbers we use the digits: 0, 1, 2,
3, 4, 5, 6, 7, 8, 9. Since we use these 10 digits and each digit in the
number stands for that digit times a power of 10, this is called “base
ten”. For example, 6325 means:
6 thousands + 3 hundreds + 2 tens + 5 ones.
Each place in the number represents a power of ten:
(6 x 10^3) + (3 x 10^2) + (2 x 10^1) + (5 x 10^0), or 6325
We could also use base 2, 3, 5, or any other that would seem most appropriate to our requirements.
Let us look at base 2, the mathematics of the
computer. There are 2 digits in base 2, 0 and 1; as with base ten, each
digit represents a power of the base number, in this case 2. For example
the number 1101, base 2, is: (1 x 2^3) + (1 x 2^2) + (0 x 2^1) + (1 x
2^0) or 13, base 10.
Base 10 is called “the common base” and was most
widely used in developing the Logarithmic tables. Let us take an
example: the logarithm of 100 in base 10, which is 2. To say it in
another way, in base 10, 10 ^2 (^ denotes exponent or power) = 100, and
the exponent, in this case, is 2. We will note this relationship in the
following way: v denotes the subscript followed by the base number, such
that, in mathematical shorthand, the logarithm of 100 in base 10 will
be written Logv10 (100) = 2.
The logarithm of 10 base 10 or Logv10(10) = 1, Logv10(100) = 2, Log v10(1000) = 3, etc. Therefore, if I add:
Logv10(10) + Logv10(100) = 3
I get a logarithm of 1000 in base 10, which is also the exponent of 10^3, or 1000.
If I subtract:
Logv10(10,000) – Logv10(100) = 2
I get 2, which is the logarithm of 100 base 10, which is also the exponent of 10^2, or 100.
In other words, adding logarithm of any number, N, to
the logarithm of any other number of that base number system, N1,
generates the logarithm of the product of those numbers:
Log(N) + Log(N1) = Log(N x N1)
Subtracting logarithm of N from N1 generates the logarithm which is the quotient of those numbers:
Log(N1) – Log(N) = Log(N1/ N)
Consequently, tedious calculations, such as
multiplication and division, especially of large numbers, can be
replaced by the simpler processes of adding or subtracting the
corresponding logarithms. Before the age of computers and rapid
calculating machines, books of the tables of logarithms of numbers were
for engineers or astronomers or anyone else who needed to calculate
large numbers.
I think the preceding discussion has been a
relatively accurate one page “textbook” introduction to logarithms and
their use. If it seems somewhat confusing, one solution is that
described by a typical professor of mathematics identified as “Dr. Ken”,
who, using the Pavlov/Thorndike approach to arithmetical learning,
suggests that:
“The way you think about it is this: the log to the
base x of y is the number you can raise x to get y. The log is the
exponent. That’s how I remembered logs the first time I saw them. I just
kept repeating ‘the log is the exponent, the log is the exponent, the
log is the exponent, the log is the exponent,…’ “
A singular problem arises when we use the
Pavlov/Thorndike approach, replacing the name of one number with that of
another, “x is y” or “the log is the exponent”, and then simply
memorizing it. If we don’t know the characteristic of action generating
the exponent, then what the heck is the logarithm anyway; if this simple
equivalency were all there was to the matter, then we have no concept
of the characteristic action corresponds to this class of numbers.
Can There Be Any Linearity At All?
by Phil Rubinstein
It is often the case that mathematicians, scientists,
and their followers are able to see anomalies, paradoxes, and
singularities, but maintain appearances by limiting such incongruities
to the moment or the instant or position of their occurrence, only to
return immediately to whatever predisposition existed in their prior
beliefs, mathematics, assumptions. It is precisely this error that
allows linearization in the small, in the typical case through reducing
said singularities to an infinite series. In fact, in even the simplest
cases, as we shall see, the singularity, anomaly or paradox requires
every term in the pre-existing system to change, never to return to its
prior form.
There is nothing complex or difficult in this. Let us
take the simplest example. Construct or imagine a circle with the two
simple folds we have used before. Now, construct the diameter and its
perpendicular bisector giving us four quadrants. Now, take the upper
left hand quadrant and connect the two perpendicular radii by a chord at
their endpoint. If we consider the radius of the circle to be 1, we
have a simple unit isosceles right triangle. Thus, from previous
demonstrations, the chord connecting the two legs of the right triangle
is the incommensurable square root of 2. Now, rotate the chord or
hypotenuse until it lies flat on the diameter, or, alternatively, fold
the circle to the same effect. The anomaly here is quite simple. Not
only is the ratio of the chord to the diameter of the circle
incommensurable, but the question arises: where does the end point of
the chord touch the diameter? How do we identify it? From the standpoint
of integral numbers and their ratios, this position cannot be located,
neither can it be named within that system. This, despite the fact that
if we take all the ratios of whole numbers between any two whole
numbers, or ratio of whole numbers, we have a continuity, that is,
between any two, there are an infinite number more. What, then, is the
location? Is there a hole there or break? While this has often been the
description, this is clearly no hole! By the simplest of constructions,
we have the location, exactly. Our chord does not “fall through,” its
end does not “fall into a hole”!
Now, we find the typical effort is to say, yes, there
is a strangeness here, but we can make it as small as we like. By
constructing a series of approximations, we get a series of ratios that
get closer and closer. Fine, one might say, but still, what is the
description or number by which we designate the location? Well, comes
the answer, the infinite series description can be substituted for the
place or number, and everything in this description is itself a number,
or ratio of numbers. Thus, we have reduced the problem in fact and
located the continuum on our diameter. One may reflect that, as
simplified as this is, it is essentially the point made by Cauchy, etc.,
although in a different context.
In the calculus of Leibniz, the differential or limit
exists as the area of change which determines the path of physical
action. Cauchy reduces that physical reality to a mere calculation, by
substituting an infinite approximation, or series for the limit, or area
of change. What is lost is simply that reality which determines the
physical action, and thus the ability to generate the idea of lawful
change as a matter of physics.
But, does the anomaly go away? Clearly, it does not.
To identify the actual position, which exists by construction, with a
series that is infinite, endless and made up of precisely components
proven NOT to be at that position, does not solve the anomaly. The
position exists, is different, and remains singular.
In fact, much more follows. Label the left end of the
diameter A and the location where the chord and diameter meet B. We
will label the intersection of the diameters O. We can now ask what
happens if we move back along the two lines, the chord and diameter. Let
us say we move from B towards O, the center of the circle. Since the
end point B of the chord is incommensurable with the diameter, if one
subtracts any rational distance towards O, the position reached is still
not commensurable, and this is so for ANY rational distance from B all
the way to A. So, every position so attained is likewise
incommensurable, as many as there are rational numbers. If I attempt to
subtract an incommensurable amount (e.g., by constructing an hypotenuse
and folding it), one has not solved the problem but merely used a
position unlocatable by integral numbers or ratios of them. In fact, we
now have a new infinity of these unlocatable positions back on the
diameter.
This process can be looked at in the following
manner. Is the position at the end of the chord greater than, less than,
or equal to a given position back on the diameter? If we take also any
position obtained by subtraction as above, do we attain a position
greater than, less than, or equal to a rational number on the diameter?
In fact, it is impossible to express the answer to these questions! One
may attempt to say that an infinite series is as close to, but always
less than, some arbitrary distance, but unless one knows beforehand the
position, one can never know whether we have passed the position, or are
not there yet. The concept of predecessors or successors or equivalence
is inoperable, inclusive of whole number cases.
Since this occurs as has been shown, everywhere on
the two lines, the only solution is to change the conception of number,
measure, or position for every position on the diameter and chord. To
simply add “irrationals” will not do, since this will leave us with
inconsistency everywhere: in effect, a line made up of locations that
cannot be compared.
The problem expands to a critical point with the
addition of the relation of the diameter to the circumference. We must
change the concept of number for every position. In this case, integers,
rationals become a case of a changed number concept or metric. Properly
understood, rather than attempting to linearize the discontinuity, we
should say every position on the line has “curvature.” This becomes more
transparent if we think of Cusa’s infinite circle as in fact the
ontological reality of the so-called straight line. Only such a
“straight” line could contain the positions cited above, could be
everywhere curved, and yet a line.
How did this occur? An anomaly was shown to exist. To
incorporate that anomaly’s existence requires a full shift in
hypothesis. More especially, any linear construction is not an actual
hypothesis, since it is unbounded and open ended, its extension is
always arbitrary. To exist, an hypothesis requires, conceptually,
“curvature,” that is, change which identifies its non-arbitrary
character. That is its hypothesis. That is, what exists in the anomaly
in the small is a reflection of its characteristic actions, its
hypothesis. There are no holes, no arbitrary leaps. Now, of course, this
leaves open the question — what other changes, hypotheses may be
reflected requiring further hypothesis. It is no mystery that any line,
or segment of a line existing in a universe of such action will manifest
those actions down to its smallest parts, and do so for each such
action.
Transfinite Principle of Light, Part I: Prologue
by Jonathan Tennenbaum
Last week my esteemed colleague Bruce Director poked
into a real hornets’ nest, when he asked: What makes people so
susceptible to the kinds of frauds now perpetrated routinely by the mass
media? Is there something {sinister} involved, a vulnerability inside
the minds of our fellow-citizens, that leads them to desire a world
{uncomplicated} by the primacy of {nonlinear curvature in the small}?
What, {sinister}? You surely don’t mean the ordinary,
simple folk, do you? The poor innocent people who are being lied to,
abused, ripped off, tormented, destroyed by the oligarchy? The ones who
are “just trying get along and raise their families?” The “noble
savages” of modern times, those honest, unassuming folk who nobly desire
nothing more than to eat and sleep and watch their favorite TV sports,
undisturbed by the world’s problems — the which, after all, they did not
create? Aren’t they so homely and nice? Don’t they have legitimate
grievances? Their lives are dull, boring, oppressive, even unbearable.
And yet if you try to organize them, if you try to {change} them, you
find they can become {very unpleasant}, very nasty indeed! Beneath their
anarchistic, individualist exteriors, they are often pathologically,
fanatically attached to their identity as “simple-minded, ordinary
folk.” Their minds seem to repel the effort at thinking outside the
tight circles of so-called “practical life.”
“Explain it in terms I can understand.” “Give me the
bottom line.” “Don’t make things complicated.” “Don’t bother me with
history and all that other fancy stuff.” “I know what you are saying.
But don’t you realize I have to make a living?”
And yet, after hundreds of millenia of human
development, can there be any excuse to remain “simple folk”? To be
ignorant of the work of past thinkers, to be indifferent to the great
drama of history and the fate of entire civilizations, nations and
cultures?
A beautiful thing is, that oligarchism is {doomed}.
Why doomed? Because oligarchism is implicitly a type of {physics}; and
as physics, oligarchism is {demonstrably false}. The demonstration is at
the same time proof of the anti-entropic character of our Universe, a
Universe which has no more place for inert “hard balls” of Newton’s
fancy, than it could long tolerate such abominations as the “sleepy
South” where “each person knows his place” and “it’s always been like
this and always will be.”
The following series is designed quite literally to
cast light on this problem. We shall focus on a celebrated experimental
discovery by Ampre’s closest friend and collaborator, Auguste Fresnel,
which overthrew once and for all the attempts by LaPlace and others to
impose Newtonianism on all of natural science. Fresnel demonstrated that
the propagation of light, while strictly lawful, is not “simple” at
all. Following Huygens and anticipating Ampre’s closely-related
demonstration of the so-called “angular force” in electrodynamics,
Fresnel showed conclusively that the notion of a straight-line
propagation of light breaks down in the “very small” — at the level of
definite, irreducible wavelengths of the order of thousandths of a
millimeter. In fact, there is no smooth, “straight-line” action anywhere
to be found in the propagation of light! Behind the gross appearance of
(approximately) straight light-rays, is a multiply-connected,
spherically-bounded rotational process which is everywhere dense in
singularities. What a wealth of activity, concealed beneath a “simple”
exterior!
Fresnel’s demonstrations at the same time became the
basis for a revolution in machine-tool design. In anticipation of what
we shall rediscover in the following couple of weeks, the reader should
ponder the following question, for example: How is it possible, using
instruments machined to a precision of, say, millimeters, to carry out
precise measurements at scales more than a thousand times smaller? Not
in a linear Universe!
By juxtaposing Fresnel’s work to the preceeding
optical discoveries of Leonardo, Kepler, Fermat and Huygens, we obtain a
glimpse of the transfinite nature of physical action — a nature which
is incomprehensible to the simple-minded, because it embodies not only
already-discovered physical principles, but also those which are
yet-to-be-discovered and yet in a sense already “present”. Those
principles are not predicates of light as an isolated, supposed
“objective” physical entity, but pertain to Man’s relationship with the
Universe as a whole.
And so our study may illuminate some secrets of the
human mind itself, and suggest joyful means by which “simple folk” might
be uplifted from oligarchical darkness.
The Transfinite Principle of Light, Part II – The Saga of the “Poisson spot”
by Jonathan Tennenbaum
We are in Paris, at the highpoint of the oligarchical
restoration in Europe, the period leading up to and following the
infamous, mass-syphilitic Congress of Vienna. Under the control of
LaPlace, the educational curriculum of the famous Ecole Polytechnique is
being turned upside-down, virtually eliminating the
geometrical-experimental method cultivated by Gaspard Monge and Lazard
Carnot and emphasizing mathematical formalism in its place. The
political campaign to crush what remained of the republican faction at
the Ecole Polytechnique reaches its highpoint with the appointment of
the royalist Auguste Cauchy in 1816, but the methodological war had been
raging since the early days of the Ecole.
With Napoleon’s rise to power and the ensuing
militarization of the Ecole in 1799, Laplace’s power in the Ecole was
greatly strengthened. At the same time, Laplace consolidated a system of
patronage with which he and his friends could exercize increasing
control over the scientific community. An important instrument was
created with the Societe d’Arcueil, which was founded in 1803 by Laplace
and his friend Berthollet and financed in significant part from the
pair’s own private fortunes. Although the Societe d’Arcueil supported
some useful scientific work, and its members included Chaptal, Arago,
Humboldt and others in addition to Laplace and his immediate
collaborators (such as Poisson and Biot), Laplace made it the center of
an effort to perfect a neo-Newtonian form of mathematical physics in
direct opposition to the tradition of Fermat, Huygens and Leibniz. In
contrast to the British followers of Newton, whose efforts were crippled
by their own stubborn rejection of Leibniz’ calculus, Laplace and his
friends chose a more tricky, delphic tactic: use the superior
mathematics developed from Leibniz and the Bernoullis, to “make
Newtonianism work.”
Poisson, whose appointment to the Ecole Polytechnique
had been sponsored by Laplace and Lagrange, worked as a kind of
mathematical lackey in support of this program. He was totally
unfamiliar with experimental research, and had been judged incompetent
as a draftsman in the Ecole Polytechnique. But he possessed considerable
virtuosity in mathematics, and there is a famous quote attributed to
him: “Life is good for only two things: doing mathematics and teaching
it.” An 1840 eulogy of Poisson gives a relevant glimpse of his
personality:
“Poisson never wished to occupy himself with two
things at the same time; when, in the course of his labors, a research
project crossed his mind that did not form any immediate connection with
what he was doing at the time, he contented himself with writing a few
words in his little wallet. The persons to whom he used to communicate
his scientific ideas know that as soon as he had finished one memoir, he
passed without interruption to another subject, and that he customarily
selected from his wallet the questions with which he should occupy
himself.”
In the context of Laplace’s program, Poisson was put
to work to elaborate a comprehensive mathematical theory of electricity
on the model of Newton’s Principia. Coulomb had already proposed to
adapt Newton’s “inverse square law” to the interaction of hypothetical
“electrical particles”, adding only the modification, that like charges
repel and opposite charges attract — the scheme which is preserved in
today’s physics textbook as “the Coulomb law of electrostatics”.
Poisson’s 1812 Memoire on the distribution of electricity in conducting
bodies, was hailed as a great triumph for Laplace’s program and a model
for related efforts in optics.
Indeed, between 1805 and 1815 Laplace, Biot and (in
part) Malus created an elaborate mathematical theory of light, based on
the notion that light rays are streams of particles that interact with
the particles of matter by short-range forces. By suitably modifing
Newton’s original “emission theory” of light and applying superior
mathematical methods, they were able to “explain” most of the known
optical phenomena, including the effect of double refraction which had
been the focus of Huygen’s work. In 1817, expecting to soon celebrate
the “final triumph” of their neo-Newtonian optics, Laplace and Biot
arranged for the physics prize of French Academy of Science to be
proposed for the best work on the theme of <diffraction> — the
apparent bending of light rays at the boundaries between different
media.
In the meantime, however, Augustin Fresnel, supported
by his close friend Ampere, had enriched Huygens’ conception of the
propagation of light by the addition of a <new physical
principle>. Guided by that principle — which we shall discover in due
course –, Fresnel reworked Huygens’ envelop construction for the
self-propagation of light, taking account of distinct <phases>
within each wavelength of propagational action, and the everywhere-dense
interaction (“interference”) of different phases at each locus of the
propagation process.
In 1818, on the occasion of Fresnel’s defense of his
thesis submitted for the Academy prize, a celebrated “show-down”
occurred between Fresnel and the Laplacians. Poisson got up to raise a
seemingly devastating objection to Fresnel’s construction: If that
construction were valid, a <bright spot> would have to appear in
the middle of the shadow cast by a spherical or disk-shaped object, when
illuminated by a suitable light source. But such a result is completely
absurd and unimaginable. Therefore Fresnel’s theory must be wrong!
Soon after the tumultuous meeting, however, one of
the judges, Francois Arago, actually did the experiment. And there it
was — the “impossible” bright spot in the middle of the shadow! Much to
the dismay of Laplace, Biot and Poisson, Fresnel was awarded the prize
in the competition. The subsequent work of Fresnel and Ampere sealed the
fate of Laplace’s neo-Newtonian program once and for all. The
phenomenon confirmed by Arago goes down in history with the name
“Poisson’s spot,” like a curse.
We shall work through the essentials of these matters
in subsequent pedagogical discussions and demonstrations. But before
proceeding further it is necessary to insist on some deeper points,
which some may find uncomfortable or even shocking. Without attending to
those deeper matters, most readers are bound to misunderstand
everything we have said and intend to say.
It is difficult or even virtually impossible, in
today’s dominant culture, to relive a scientific discovery, without
first clearing away the cognitive obstacles reflected in the tendency to
reject, or run away from, the essential <subjectivity> of
science. Accordingly, as a “cognitive IQ test” in the spirit of Lyn’s
recent provocations on economics, challenge yourself with the following
interconnected questions:
1) Identify the devastating, fundamental fallacies behind the following, typical textbook account:
“There were two different opinions about the nature
of light: the particle theory and wave theory. Fresnel and others
carried out experiments which proved that the particle theory was wrong
and the wave theory was right.”
2) Asked to explain the meaning of “hypothesis” a student responds:
“An hypothesis is a kind of guess we make in trying to explain something whose actual cause we do not know.”
Is this your concept? Is it right?
3) What is the difference between what we think of as
a property of some object, and a physical principle? Why must a
physical principle, insofar as it has any claim to validity, necessarily
apply to all processes in the Universe, <without exception>?
If you encounter any difficulty in answering the above, reread Lyn’s “Project A.”
Next week: Leonardo and the paradox of the “camera oscura.”
Transfinite Principle of Light, Part III: The Phantom of Linearity
By Jonathan Tennenbaum
Look at Leonardo’s drawings of rays of light
reflected in a curved mirror. Leonardo draws the incoming rays as
parallel straight lines. Reflected off the mirror, the rays form an
envelope — a curve that Leibniz’s friend Tschirnhaus later called a
{caustic}. Looking at the drawing, we might think to ourselves: “Here
Leonardo has shown how the complex is generated by the simple. See how
this beautiful curve, the caustic, is created from the simple,
straight-line rays, which are the natural, the elementary form of light
propagation.”
But, stop to think: Did Leonardo really think that
way? Did he believe that straight-line action is primary, and curved
forms are secondary? Was Leonardo a Newtonian?
Or have we gotten it backwards? That Leonardo saw, in
the production of the caustic, a characteristic manifestation of the
{fundamentally non-linear, high-order process} underlying light, and
which generates the appearance of straight-line rays as a mere {effect}?
Looking more carefully at Leonardo’s manuscripts with
our mind’s eye wide open, the evidence jumps out at us. Indeed,
Leonardo even states it explicitly: The propagation of water waves,
sound and light alike are based on a {common principle of action}; that
principle is not straight-line action, but curved, (to a first
approximation) circular action!
Leonardo implies, in fact — as he demonstrated for
the case of water waves — that the {action} which generates the outward
propagation of light from a source, is {not} basically directed in the
“forward” direction, i.e., outward from the source, but essentially
perpendicularly, {transverse} to the apparent direction of propagation!
Now let’s turn to the contrary, so-called “emission
theory” which is commonly attributed to Newton (although much older),
and which he elaborated in Book III of his famous “Opticks”. Newton
writes, for example: “Are not the rays of light (streams of) very small
bodies emitted from luminous substances? For such bodies will pass
through uniform media in straight lines without bending into the shadow,
which is the nature of rays of light.” Newton adds many other
arguments, which I shall not reproduce here.
Doesn’t this picture indeed seem very agreeable to
our naive imagination? Indeed, someone might plausibly argue that: 1)
since light evidently moves outward from the source in straight lines
and 2) since no motion is possible without some material bodies which
are moving, therefore 3) the light rays must consist either of material
particles (photons?) or maybe a continuous fluid emitted from the source
and moving outward from it.
And how to account for the {bending} or change of
direction (diffraction) of light rays, when they pass from one medium to
another (i.e., from air to water) or through a medium of changing
density? Simple! Since the “natural” or elementary motion is
straight-line motion, the bending of the trajectories of the particles
forming the rays, must be due to some “forces”, which are pulling the
rays (or the particles making up the rays) out of that straight motion,
into curved trajectories. What could be more self-evident than that?
Newton actually provides a program for elaborating
this emission theory more and more: By studying the laws of diffraction
of light rays, and other aspects of their behavior in passing through
various materials, we should {deduce}, by mathematics, the microscopic
forces which must be acting upon the light particles in interaction with
the medium. And then from those “force laws”, once established, we will
in turn be able to calculate the behavior of light rays under arbitrary
conditions.
Newton puts his own work on gravitation and planetary
motion forward as the model for this, stating, in the famous “General
Scholium” from Philophiae Naturalis Principia Mathematica:
“Hitherto we have explained the phenomena of the
heavens and of our sea by the power of gravity, but we have not yet
assigned the cause of this power…. I have not been able to discover the
cause of those properties of gravity from phenomena, and I frame no
hypotheses; for whatever is not deduced from the phenomena is to be
called a hypothesis, and hypotheses, whether metaphysical or physical,
whether occult qualities or mechanical, have no place in experimental
philosophy. In this philosophy particular propositions are inferred from
the phenomena and afterwards rendered general by induction. Thus it was
that the impenetrability, the mobility and the impulsive force of
bodies, and the laws of motion and of gravitation, were discovered. And
to us it is enough that gravity does really exist and act according to
the laws that we have explained…”
This same argument was repeated by the Marquis de
Laplace, the self-proclaimed high priest of Napoleon’s “orthodox
Newtonianism”, in an 1815 attack on the early work of Fresnel. Laplace
said that in view of the “success” of Newton’s emission theory, he
greatly regretted that anyone would presume
“to substitute for it another, purely hypothetical
one, and which, so to speak, can be manipulated at will: that of
Huygens’ ondulations. One must limit oneself to repeating and varying
experiments and deducing laws from them, that is, coordinating facts,
and avoid any undemonstrated hypothesis.”
But did you pick up the “big lie” which Newton told in the passage cited above? Don’t let him get away with it!
Newton claims, among other things, that his law of
gravitation was “deduced from the phenomena”, without the use of
hypothesis. That is a bald-faced lie. As even Laplace admits, Newton
obtained his “force law” by inverting Kepler’s construction for the
elliptical orbital motion of the planets. But Kepler’s construction was
by no means deduced from the visible motion of the planets; indeed, what
could anyone “deduce” from the wild, tangled mass of looping motions of
the planets, as seen from the Earth? Rather, Kepler arrived at his
results step-by-step through a series of {creative hypotheses} — by
cognition! — as documented by Kepler himself in his works, from the
Mysterium Cosmographicum through to the New Astronomy. Even Newton’s
so-called force law is no deduction from Kepler’s work, but was obtained
only by imposing a whole array of {arbitrary assumptions} which are
neither in Kepler, nor “deduced from the phenomena”, nor otherwise
demonstrated in any way. So, for example, the hypothesis that space has
the form of a simple Cartesian manifold, and that straight-line action
is elementary.
Now, step back from the specifics of this “big lie”
and ask yourself: Why are so many people, even scientists, fooled so
much of the time? Could it be, because the supposed elementarity of
straight-line action is merely a lawfully-generated, externalized
{image} or artifact of a defective form of mental processes?
Exclude {cognition} from mental processes. What is
the typical form of action in the “mental vacuum” so created? The
characteristic of deduction, as the “elementary” form of non-cognitive
reasoning, is that no cognitive considerations are permitted to disturb
the “perfect vacuum” in which the deductive chains of logical premises
and conclusions are unfolded. No “leakage” of reality from outside the
system, which could call its basic assumptions into question, is
permitted to interfere with the growth of the theorem-lattice.
Now look, from this standpoint, at what Riemann had to say about Newton’s famous “First Law of Motion”:
“I find the distinction that Newton makes, between
laws of motion, axioms and hypotheses, untenable. The law of inertia is
an hypothesis: If a material point were all alone in the Universe, and
if it were moving with a certain velocity, then it would keep moving
with the same unchanged velocity”.
Now here comes a simple-minded fellow, and says to
himself: “Well, isn’t that First Law self-evident? After all, {if there
were nothing around in the Universe} to interfere with the particle’s
motion, then nothing would change that motion, either in direction or in
speed. Since there would be no reason for it to bend in one direction
rather than another, or to slow down or speed up, the particle would
keep moving at a constant velocity in a straight line.” So, in
particular, straight-line motion is elementary!
What happened? With his logical premise of a Universe
consisting of nothing but a single particle alone in an infinitely
extended empty space, our simple-minded fellow has thrown cognition (and
the real Universe!) out of the window. He has put himself into a wildly
arbitrary phantasy-world; and now proposes, as Newton did, to make that
phantasy-world into his yardstick for the real Universe!
If we dig a bit deeper, our fellow might come up with
another logical idea: the simple precedes the complex, so to understand
the complicated real Universe, we have to break it down into simple
parts, into simple hypothetical situations. Then we can deduce the
complex situations from the simpler ones. But what if the supposed
“simple parts” don’t exist and could not exist in and of themselves?
What if the only “simple” existence were the indivisible unity of the
Universe as a whole, a Universe graspable only by cognition? But
cognition is not simple in the way our vacuum-headed fellow imagines
rational thinking to be.
From this it should be obvious, that the issue fought
out by Fresnel and Ampere against Laplace, by Kepler against Galileo,
by Leibniz against Newton and so forth, is not one of this or that
theory or doctrine. It is emphatically not the so-called wave theory
versus the particle theory. The issue, as emphasized in Plato’s
Parmenides, is the human mind.
Ask yourself: what is the transverse nature of the action, upon which the physical growth of any economy is based?
Transfinite Principle of Light, Part IV: Least Time
by Jonathan Tennenbaum
In last week’s pedagogical discussion, Phil
Rubenstein provoked us with a beautiful glimpse into Leibniz’s notion of
physical space-time, observing that:
“[T]he totality of space is altered when an action
introduces something incompatible to the previous ordering, and that is
what introduces real time as changed space. Thus, all of the space-time
is truly changed and the primacy of facts is altered.”
Most of us have been trained or otherwise induced to
think of events in terms of an implicitly fixed ordering of the
Universe. When an event occurs, we too often only ask ourselves: “Where
does this event fit into the scheme of the world as I know it?” or “What
category does it belong to?” Whereas Phil (following Leibniz) wanted to
get us to look out for the anomalous characteristics of an event, and
to ask ourselves, instead: “What is the change in ordering of the world,
which this anomaly implies?” Or even better: “How does this event open
up a potential flank, by which I might change the current ordering of
the world into a better one?”
As Phil also pointed out, the two modes of thought
are associated with two very different notions of causality. In the
first, we put our noses close to the ground and follow events one at a
time, in chains of “cause-and-effect.” So, A causes B, B causes C, C
causes D and so on like a chain of dominoes, each falling over and
pushing the next one in turn. If someone asks, “Why did event X occur?”,
our answer will be: “Because W occurred, and W caused X.” And W
occurred because of V, V because of U and so forth ad infinitum (or
until we find the guy who pushed over the first domino, Aristotle’s
“Prime Mover”!). But the platonic mind would rather ask: “Who arranged
the dominoes that way, so that the trajectory of apparent
cause-and-effect took that particular form?”
When we raise ourselves to the second, higher level,
we look for those crucial actions and events, that define the {total
geometry} (i.e. ordering) within which entire ranges of other events
occur, take a certain form, and tend toward a pre-determinable array of
outcomes. This latter standpoint is congruent with Kepler’s conception
of a planetary orbit and brings us to Leibniz’ notion of {sufficient
reason}. So, referring in his “Principles of Nature” to the higher
(transfinite) ordering of the Universe as a whole, Leibniz said:
“The sufficient reason for the Universe cannot be
found in the sequence of contingent events…. Since the present motion of
matter comes from the preceeding, and that one from an earlier still,
one never comes closer to the answer, however far one goes, because the
question always remains. Thus it is necessary that the sufficient
reason, which does not require another reason, {lies outside this series
of contingent events}, and this must be sought in a substance which is
the cause, and is a necessary being … this last reason of things is
God.”
A beautiful example for the two conflicting outlooks
is provided by Pierre Fermat’s discovery of the Principle of Least Time
on the basis of he called “my method of maxima and minima.” [fn1] This
example is all the more notable, as Leibniz himself used it repeatedly
in his polemics against Descartes and the Cartesians.
To set the stage, I should report that around 1621
the Dutch astronomer Snell (who also made major contributions to
geodesy) studied the bending of light rays when passing from one medium
(for example, air) into another medium (say, water). In each of the two
media, insofar as they are relatively homogenous, the propagation of
light appears to occur along straight-line pathways. But it had long
been recognized, that light entering from air into water at a certain
angle, propagates at a different, much steeper angle inside the water.
Now Snell studied the functional relationship between the angle (call it
X) which the ray makes to the vertical {before} entering the water, and
the angle (Y) which is formed with the vertical by the direction of the
ray {after} it has passed into the water. He discovered a very simple
relationship, which holds quite precisely within certain limits: namely
that the {sines} of the two angles are {proportional} to each other. To
make these relationships clear, draw the following “classical” diagram,
which Leibniz, Fermat et al. employed in their discussions of these
matters.
Let a line segment AB represent the surface of the
water and let point C represent the locus on AB where the ray of light
enters the water. Draw a circle around C. Mark by “D” the point on the
upper half of the circle (the part in the air), at which the light ray
enters the circle on the way to C, and mark by “E” the locus at which
the ray, now propagating in water, crosses the lower half of the circle.
The line segments DC and CE represent the directions of the light ray
before and after passing from air into water. Now draw the vertical line
L through C. The angle between DC and L, is what we called X above, and
the angle between CE and L is Y.
Finally, project D and E horizontally (i.e.
perpendicularly) onto L, defining two points F and G which are the
projections of D and E, respectively, onto the vertical L. (DF and EG
are proportional to the {sines} of the angles X and Y.)
Now imagine we vary the angle at which the ray enters
the water, while keeping the entry point C fixed. In other words, D
moves along the upper part of the circle and the angle X changes
correspondingly. What happens to angle Y and the position of E?
Snell found that in the course of these changes, {the
ratio of DF to EG remains constant}. For the case of air and water, it
turns out that DF:EG = (approximately) 1.33 : 1. From this, we can
determine the angle Y corresponding to any given angle X, by a simple
geometrical construction.
But what is the explanation of this relationship, its
“sufficient reason”? Leibniz himself was convinced that Snell did not
find his law by mere empirical trial-and-error, but that he worked from
an {hypothesis} derived from the work of the ancient Greek scientists
who had discovered an analogous (but simpler) law for the {reflection}
of light over 1500 years earlier. While Snell’s original train of
thought seems to have been lost, Rene Descartes later (1637) restated
the same law, which he claimed to have discovered by himself, and
offered an explanation or “proof” based on his own special notion of
physics and the nature of light.
Descartes’ argument, as published for example in his
“Dioptrique,” is somewhat muddled and difficult to present in a few
words. Essentially, Descartes likened the motion of light to that of a
small ball or other object which encounters greater or lesser resistance
along the path of its motion. The circumstance, that the light ray is
bent toward the vertical direction on passing into the water — i.e.
becomes “steeper” in its passage through the water — Descartes took as
evidence that the {light moves more easily through the water} and is
less retarded in its motion, than in the air. At the point of transition
into the “easier” medium of the water, Descartes thought, it is as if
the ball (the light) would pick up an extra “kick”, continuing at a
steeper direction.
Now, disregarding the vagueness and confusing nature
of Descartes’ argument, his thinking is clearly trapped in what we
referred to above as the first mode: namely to follow a process from one
step to the next within a fixed notion of ordering, which is (in
Descartes’ case) essentially the naive housewives’ “common sense” notion
of the motion of material bodies.
Now in closing, let us listen to what Fermat has to say, in his “Method for the Research of the Maximum and Minimum”:
“The learned Descartes proposed a law for refractions
which is, as he says, in accordance with experience; but in order to
demonstrate it he employed a postulate, absolutely indispensible to his
reasoning, namely that the propagation of light takes place more easily
and faster in more dense media than more rarefied media; however, this
postulate seems contrary to natural light.”
[“Natural light” was a common expression for “Reason”. Fermat is poking fun at Descartes. He continues:]
“While seeking to establish the true law of
defraction on the basis of the contrary principle — namely that the
movement of light is easier and faster in the less dense medium than in
the more dense one — we arrived at exactly the law that Descartes had
announced. Whether it is possible to arrive at the same truth by two
absolutely opposing methods, that is a question we will leave to those
geometers to consider, who are subtle enough to resolve it rigorously;
for, without entering into vain discussions, it is enough for us to have
certain possession of the truth, and we consider that preferable to a
further continuation of useless and illusory quarrels.
“Our demonstration is based on the single postulate,
that Nature operates by the most easy and convenient methods and
pathways — as it is in this way that we think the postulate should be
stated, and not, as usually is done, by saying that Nature always
operates by the shortest lines … We do not look for the shortest spaces
or lines, but rather those that can be traversed in the easiest way,
most conveniently and in the shortest time.”
Next week we shall look more closely, through the eyes of Leibniz, at Fermat’s discovery and the error of Descartes.

1. Here is a deliberately challenging quote from a
1636 letter by Fermat to Roberval, in which he boasts about the scope of
his method:
“On the subject of the method of maxima and minima …
you have not seen the most beautiful applications; because I make it
work by diversifying it a bit. Firstly, in order to invent propositions
similar to that of the (parabolic) conoid which I told you about last;
2) In order to find the tangents of curved lines…; 3) To find the
centers of gravity for all sorts of figures…; 4) To solve number
theoretic problems … it is in this… that I found an infinity of numbers
which do the same thing as 220 and 284, namely that the sum of the
divisors of the first equals the second and the sum of the divisors of
the second equals the first; and if you want another example to give you
a taste of the question, take 17296 and 18416. I am sure you will admit
that this question and those of the same sort are very difficult…. And
so you see four kinds of questions which my method embraces, which you
probably didn’t know about.”
Transfinite Principle of Light, Part V: Time To See the Light
by Bruce Director
Last week, you were introduced to a paradigmatic case
of a discovery of a universal principle, Fermat’s principle of
“Least Time.” Contrary to textbook-educated commentators, Fermat’s Least
Time principle, is not a property of light. Rather, it is
a characteristic of the Universe, from which light’s properties unfold.
The irony is, that this universal characteristic of Least Time, is
discovered in its unfolded form, but only KNOWN as a universal
principle. For that reason, it epitomizes the discovery of a principle
that corresponds to a change in hypothesis from an n- to an n+1-fold
manifold, connected with a corresponding change from an m- to an
m+1-fold manifold. Consequently, it deserves your careful attention and
study.
To summarize: the Classical Greeks had already
discovered a special case of this principle, through the investigation
of reflected light (catoptics)/1. The Greeks found that the angle at
which light is reflected from a shiny surface, is equal to the angle at
which the light strikes that surface. Simply stated, the angle of
incidence equals the angle of reflection. The equality of these angles,
minimizes the length of the path from the source of the light, to the
reflecting surface, to the eye. However, this principle is NOT a
property of light. It is a manifestation of a universal characteristic:
that nature always acts along the shortest path.
The phenomenon of refraction (the change in direction
of light when it travels from one medium to another, such as from air
to water), appears, at first, to contradict this
universal characteristic, as the change in direction at the
boundary between the two media, makes the path of the light longer,
than were it to continue in the same direction across the boundary.
More than one and one-half millennia after the
Classical Greek period, Willibrod Snell showed that when light
is refracted, the change in direction is such that the sine of the angle
of incidence and the sine of the angle of refraction are always in
constant proportion. (See last week’s pedagogical.) The Greek principle
of reflection (in which this proportion is one, as equal angles will
have equal sines), can thus be seen as a special case, or boundary, of
Snell’s more universal principle. Yet, the length of the path of the
light under refraction, is still not the shortest path, as in the case
of reflection.
While the details of Snell’s reasoning are not
entirely known to us, it had been conjectured that the observed
refraction resulted from a change in the velocity when light travels
through different media./2 Under this idea, it can be shown, that
the different velocities are in the same proportion as the sines of the
angles of incidence and refraction. Or, in other words, Snell’s law of
refraction is, itself a reflection of a physical principle, that
velocity of light changes when traveling in different media. (In his
“Treatise on Light,” Huygens has a simple and direct geometrical
demonstration of this concept, to which the reader is referred.)
Descartes, believing that light was a stream of
particles, adopted the conjecture that such particles would travel
faster in denser media. From this, he reformulated Snell’s law and
claimed it as his own, a fraud so blatant that even Descartes’
apologists no longer can defend it.
Pierre de Fermat adopted the opposite view, that
light traveled slower in denser media. But, much more
importantly, Fermat came to this idea, not by conjecturing on the
properties of light, as Descartes did, but from the standpoint of a
new universal principle that he hypothesized: to wit, that nature always
acts according to the least time. That is, that the longer path the
light travels when refracted, is actually the path that takes the
shortest time. From the standpoint of the earlier Greek discovery of
reflection, the universal principle that nature seeks the shortest path
in space, has been transformed into the principle of shortest path in
space-time. A transformation from a universal hypothesis of n
dimensions, to a universal hypothesis of n+1 dimensions. (Hypothesis is
used here in the rigorous Socratic terms defined by LaRouche, not
the banalized general usage concept more closely equated with the verb
“to guess.”)
Or, in the words of Fermat, quoted in last week’s pedagogical discussion:
“Our demonstration is based on the single postulate,
that Nature operates by the most easy and convenient methods
and pathways — as it is in this way that we think the postulate should
be stated, and not, as usually is done, by saying that Nature always
operates by the shortest lines…. We do not look for the shortest spaces
or lines, but rather those that can be traversed in the easiest way,
most conveniently and in the shortest time.”
Leibniz in his “Discourse on Metaphysics,” addresses this question this way:
“The method of final causes is more easy and can
often be used to divine important and useful truths, which one would
have to seek for a long time by a more physical approach, for
which anatomy provides major examples. Thus I believe that Snell, who is
the first discoverer of the laws of refraction, would have had to spend
a long time finding them, if he had started by first trying to find out
how light is formed. Rather, he apparently followed the method which
the ancients used in catoptics, which is based on final causes. By
looking for the easiest pathway to pass light from a given point to
another given point by reflection on a given plane (supposing this is
the intention of Nature), the ancients found the equality of the angles
of incidence and reflection, as one can see from a little treatise of
Heliodor of Lariss, and elsewhere. Which is what Snell as I believe, and
after him (although without knowing from his) Fermat applied very
ingeniously to refraction…. And the proof which Descartes’ wanted to
give for the same theorem, by the method of efficient causes, would need
much improvement to be as good. At least, there is reason to suppose
that Descartes would never have discovered the law in that way, unless
he had learned something in Holland about Snell’s discovery.”
“Descartes thought the opposite of what we think
concerning the resistance of various media (to the propagation of
light). That is why the very illustrious Spleissius, a man well versed
in these matters, has no doubt that Descartes, when he was in Holland,
saw Snell’s theorem; and in fact he remarks that Descartes had the habit
of omitting mention of authors, and takes as an example the vortices in
the Universe which Giordano Bruno and Johannes Kepler pointed to, in
such a way that only the word itself was missing in their work. It
happens that Descartes, in order to prove his theorem by his own
efforts… From which Fermat correctly concluded that Descartes had not
given the real reason for his theorem.”
The Cartesians, Galileans, and the whole plethora
of Aristotelian-Manichean sects, squealed with rage, at
Fermat’s principle of Least Time. How could Fermat say that light
sought the shortest time? Why, that would mean that either, light
would have to have some “intelligence” by which to “decide” whether its
choice of path was using up the shortest time, or, there would have to
be some pre-arranged “track,” like Ptolemy’s solid orbs, that guided the
light along the shortest path.
These objections are identical to those raised
against Kepler, who demonstrated that the elliptical planetary
orbits, rather than uniform circular ones, are the pathways
that correspond to the universal space-time characteristic of the solar
system. Kepler dethroned Ptolemy’s demi-gods and solid orbs, along with
the poly-copulating Olympians, from whom Ptolemy and his fellow
Bogomils, drew their authority.
Taking up the defense of Fermat’s principle, Leibniz dealt the decisive blow to the Cartesians:
“…Thus we have reduced to pure Geometry all of the
laws which confirm experimentally the behavior of light rays, and
have established their calculus on the basis of a unique principle, that
you can grasp following a specific causality, but providing you
consider appropriately the case in point: indeed, neither can the ray
coming from C make a decision [1] about how to arrive, by the easiest
way possible, at points E, D, or G, nor is this ray self-moving towards
them [2]; on the contrary, the Architect of all things created light in
such a way that this most beautiful result is born from its very nature.
That is the reason why those who, like Descartes, reject the existence
of Final Causes in Physics, commit a very big mistake, to say the least;
because aside from revealing the wonders of divine wisdom, such
final causes make us discover a very beautiful principle, along with the
properties of such things whose intimate nature is not yet that clearly
perceived by us, that we can have the power to explain them, and make
use of their efficient causes, along with their artifacts, such as the
Creator employed them in order to produce their results, and to
determine their ends. It must be further understood from this that the
meditations of the ancients on such matters are not to be taken lightly,
as certain people think nowadays.”
Reflect on that, until next week.
1/ The history of these Greek investigations
deserves careful study by us, as its development in textbooks is
vague and confusing. For pedagogical purposes, and for posterity’s sake,
it needs to be pulled together by someone wanting to do a service to
humanity.
2/ This is also an area of historical research which is necessary for us to fill out.
Transfinite Principle of Light, Part VI: Passion and Hypothesis
by Jonathan Tennenbaum
There is a tendency for people to misconstrue and
banalize ad absurdum the polemic Lyn has developed about the need to
change fundamental assumptions. Some think to themselves: “Lyn says that
assumptions are bad. So I’ll play it safe. I won’t make any assumptions
at all.”
This wimpy attitude, already strong among
baby-boomers, is even more pronounced among Generations X and Y. These
people have resolved never to commit themselves fully to anything, never
to make a strong emotional investment, never to make a decision which
might irreversibly change their lives: “No, no I don’t go there” is the
motto. Their policy is to “keep all the doors open,” particularly the
hind doors through which to escape when the going gets too tough.
Ironically, no behavior demonstrates the influence of
hidden ontological assumptions more clearly, than the obsessive,
schlmiehl-like behavior of people trying to “play it safe,” hiding
behind an illusion of “objectivity,” “sticking to the facts,” and
“playing according to the rules.” Whereas today the very survival of the
world depends on {strong hypotheses} — hypotheses discovered,
transmitted, and executed with the most impassioned quality of moral
commitment.
So, Schiller said, he who would not give up his life,
will not gain it. It is impossible to make or relive a scientific or
equivalent quality of creative discovery without risk, without
sacrificing some cherished thing inside oneself and even confronting
something akin to the fear of death.
As an example, let us listen to Brahms’ student
Gustav Jenner, as he describes how Brahms forced him through the
agonizing process of knowing, as opposed to superficial learning. Jenner
recounts his first encounter with Brahms. Personally, Brahms was very
kind and friendly to the budding young composer. But when it came to
criticizing the compositions Jenner had put in front of him — naturally
the ones Jenner was most proud of — Brahms’ remarks were devastating:
“After it was all over, I felt like someone who,
after wandering long on a false path, thinks his goal is near, but
suddenly realizes his error and now sees his goal vanish into the
distance…. Despite the mercilessly strict judgement which my labors
elicited from him, not a single ironical or even an angry word fell from
his lips…. He simply demonstrated to me, relentlessly and without
brooking any contradiction, that I didn’t know how to do anything …
After a stringent examination concerning what I had been doing with my
life up to then, Brahms said: `You see, in music you have not yet
learned anything in an orderly fashion; for, everything you’ve been
telling me about the theory of harmony, your attempts to compose,
instrumentation, and so forth, I count as nothing.'”
That was only the beginning. After Jenner had moved
to Vienna to study under Brahms, the old master became more still more
strict and rigorous with him than before.
“I never again heard from Brahms an encouraging word —
let alone praise — about my works…. It took a long time before I truly
learned how to work … Only a full year later did Brahms say to me on one
occasion, `You will never hear a word of praise from me; if you cannot
tolerate that, then everything within you is only of value by virtue of
the fact that it will fail.'”
But what did Brahms teach Jenner? For that I advise
everyone to read all of Jenner’s short book. Here I just want to quote
from one passage, especially relevant to the point at hand:
“I learned the most not by him pointing out my
mistakes per se, but by his revealing to me how they had come about in
the first place…. From his experience he told me: `Whenever ideas come
to you, go take a walk; then you’ll find that what you had thought was a
finished idea, was only the beginnings of one.’ He would repeatedly
seek to sharpen my distrust in my own ideas. I have often had the
experience that precisely such thoughts which become lodged (in the
mind) like an idee fixe, pose a natural barrier to creativity, because
one has fallen in love with them and, instead of mastering them, has
become their slave. `Pens exist not only to write, but also to cross
things out,’ said Brahms, `but be careful, because once something has
been set down, it is hard to take it away again. But once you realize,
that, good though it (a passage) may be in itself, it is not appropriate
here (at a given place), don’t mull it over any longer, but simply
cross it out.’ And how often we do we not try to save a passage, only to
ruin the whole!… When Brahms, with his impartial criticism, reproached
me for precisely those passages, I felt surprised and hurt at the
beginning, because these had been my favorite passages — until I saw
that I hadn’t found the disrupting element because I had unconciously
proceeded from the idea, that this passage must stay in, no matter what.
I have had to feel the bite of those pronouncements by Brahms in my own
flesh; they are the result of his long experience and unbending
self-criticism.”
Helped by Brahms to become aware of and correct his
own weaknesses of thinking, Jenner wages a war against his own tendency
toward superficiality, his frequent infatuation with his own “pet” ideas
at the expense of truth, his tendency to be distracted by unimportant
particularities instead of concentrating on what is really essential.
Does that sound familiar to anyone?
But is the conclusion from this teaching, to avoid
having ideas, to not risk putting forward hypotheses, for fear they
might turn out to be wrong? Hardly! Nothing could be more boring, more
totally useless, than a composer who writes “according to the rules,”
and who is unwilling to “live dangerously” by making bold and daring
(but true!) hypotheses.
The difficulty Jenner describes — to overcome one’s
attachment to strongly-held ideas and habits of thought in a rigorous
search for truth — arises in essentially identical fashion in science
and every other field of creative endeavor.
But in this regard, unfortunately, people in our
organization sometimes fall into a trap: Our ideas are (generally
speaking) far superior to those predominating in society nowadays; and
thus it appears very easy (or should be) to attack and ridicule the
“obviously” silly ideas of ordinary people, without feeling the need to
go through {in ourselves} the agony Jenner experienced. Yet, Brahms’
authority as a teacher came from {exactly that}: from Brahms’ own
agonizing struggle for rigor and truth vis-a-vis his own mind, and not
merely from his superior ideas, knowledge and experience as a composer.
Thus, the main points of reference for ridiculing and
refuting wrong or “silly” ideas and habits in others, are the successes
one has had in confronting and overcoming one’s own imperfections. That
includes insight into the {lawful nature} of human imperfections and
the powerful attachments people often form to them. Thereby, one can put
one’s own past errors and imperfections to good use, demonstrating once
more Leibniz’s profound principle of “the best of all possible worlds.”
Turning now to physical science proper, it is too
cheap, and we cheat ourselves if we would do this, to merely ridicule as
“obviously wrong” the theories and hypotheses which a given discovery
refutes, overthrows, or supersedes. True, in history to date, science
has hardly existed except in a constant state of war against
oligarchism; and as we have repeatedly documented (as in the case of
Fresnel and Ampere), the oligarchical faction (embodying a “{negative}
higher hypothesis”) is commonly the active promoter of the inferior
hypotheses against which significant discoveries were explicitly or
implicitly directed, as means to overcome what had been transformed into
the “prevailing public opinion” among scientists and others.
However, to the extent we might tend, too quickly and
cheaply, to divide ideas and hypotheses into {self-evidently} good and
true on the one hand, and {self-evidently} false and bad on the other,
we trivialize the struggle inside the mind of the creative scientist and
cheat ourselves out of the possibility of really reliving a discovery.
For, the oligarchical element lies not in the inferior idea pe se, but
in the deliberate clinging to it, in the satanic {assertion} of
backwardness and regression as a {principle} opposed to the principle of
perfection. An animal is not an evil thing; but a man who behaves like
an animal, is.
The immediate point I wish to stress, is this: the
strength of belief in certain assumptions and hypotheses, which the
creative scientist must confront in the process of discovery, is (in
many if not most cases) not {simply} a product of oligarchical
tampering. To a greater or lesser extent those assumptions and
hypotheses arose as the product of earlier discoveries, and their
relative adequacy was supported by vast arrays of corroborating evidence
and by the positive economic impact (increase in Man’s per-capita power
over Nature) of technological developments based upon them. In the
light of such impressive, even overwhelming grounds to believe in the
validity of the relevant assumptions and theories, the psychological
difficulty facing the discoverer is qualitatively greater than that of
merely refuting an “obviously wrong” idea.
Think of a classical tragedy where the final curtain
falls on a stage littered with dead bodies. If the audience had
developed no strong and justified engagement, admiration for, or
sympathy with the tragic hero or others among the characters whose lives
thus ended, what would happen to the tragic effect of the play? So, in
the course of scientific discovery, as in the composition of music and
drama, some ideas must “die” in order that higher ideas might be
expressed. The greater the apparent attractiveness, validity and
comprehensiveness of the ideas successfully superceeded, the greater the
power embodied by the creative discovery.
– An Inferior, but Fruitful Hypothesis –
For these reasons, before proceeding further with the
discoveries of Fermat, Bernoulli, Leibniz, Huygens, and Fresnel, we
should look a bit closer at the notion which these discoveries,
culminating with Fresnel, finally refuted: The notion that light
propagates in the form of “rays” projected outward from the luminous or
illuminated object; and that to a very high degree of precision these
rays take, in a uniform medium, the form of straight lines.
Before rushing to reject this notion out-of-hand
(i.e. simply because of the occurrence of straight lines), let us for a
moment reflect on the theorems which flow from it. We shall find, in
fact, that this descriptive notion of light rays is {extremely useful
and fruitful}, as Leonardo himself and many others demonstrated in
countless ways. Its eventual rejection by Huygens and Fresnel is by no
means so easy and self-evident, as might appear after-the-fact.
Among other things, the principles of so-called “ray
optics” was the basis of perspective, and (supplemented by Fermat’s
principle) for the analysis and development of lenses. It is still
employed on a large scale today in the design of optical instruments,
even though the notion of “ray” itself — as something supposedly
self-evident and elementary — was decisively refuted by Fresnel and
superseded by an entirely different principle.
– Ray Optics and the Camera Oscura –
The idea of resolving light propagation into “rays”
is a not a self-evident idea simply drawn from sense-perception, but an
{hypothesis}. True, Nature sometimes provides rare circumstances, such
as sunlight shining through a break in clouds, where we seem to “see”
straight-line rays. However, it is a big step to go from that mere
spectacle to a general conception, and indeed the gateway to that
conception is guarded by many paradoxes. For example: if every point of
every illuminated object emits rays of light in all directions, so that
the entire space is filled with an infinity of crisscrossing rays, then
how can we ever see anything clearly? And won’t the rays constantly be
colliding into each other?
Leonardo said every illuminated object “fills space
with pictures of itself.” But if we stand in the middle of a room and
hold up a piece of blank paper, we certainly don’t see any pictures
projected on it! The reason is not hard to imagine: the light arriving
at any given location on the paper arrives from all objects and comes
from all directions at the same time; it is consequently mixed up and
jumbled together, and no image can result.
How, then, are we able to see anything at all? How do
our eyes manage to organize and untangle the light? Renaissance
experiments with the so-called “camera oscura” provide a preliminary
hypothesis. Build a closed chamber without windows (a closed box) whose
walls and ceiling are completely opaque to light. Install a screen on
one of the inside vertical walls of the room, and make a small hole in
the middle of the opposite wall. An observer sitting inside the room
will see, projected onto the screne, an image of the world outside the
chamber! In fact, the image on the screen corresponds to what the
observer would see, if he were to look outside directly through the hole
— except that the image on the screen is upside-down!
Do the experiment, or an equivalent one. What is the
difference between the two situations: A) holding up a piece of paper in
the middle of a room, and finding no image at all B) putting up the
same piece of paper on the wall of the “camera oscura” (or equivalently,
imposing an opaque barrier with a small hole, between illuminated
objects and a screen)?
Evidently, the hole in the wall fulfills the function
of a {lens}, organizing the propagation of light in such a way, that
the image appears on the screen. But note, that if we move the screen
directly up to the hole, the images disappear, and we get nothing but an
undifferentiated spot of light. Not the hole itself, but the total
arrangement of hole and the screen held at a significant distance away,
provides the relevant organizing function.
Now, account for the function of the “camera oscura”
as a {theorem} based on the hypothesis, that light propagates in
(approximately) straight-line rays. Account also for the circumstance,
that the images on the screen are slightly blurred, depending on the
size of the hole.
Related to this, derive as a theorem another,
apparently anomalous phenomenon known to the Greeks and discussed at
length by Leonardo: The shadow of any object placed in the rays of the
Sun, and projected onto a screen at a suitable distance, is not simple
and sharp, but consists of a dark interior region (the “core shadow”)
outside of which the light gradually increases. Determine the
geometrical law by which the relative sizes of the core shadow and the
“blurred” partial shadow change, as the distance between object and
screen is varied. The analysis is brilliantly confirmed by such
phenomena as eclipses of the Sun.
Examine, thus, these and other fruitful consequences of “ray optics” without the oligarchical admixture of Newton, et al.
Now begin to appreciate the shocking, jarring impact
of Fresnel’s hypothesis, that shadows are produced “holographically”,
i.e., by {interference} of active wave processes inside and around the
shadow area itself, and not merely through the blocking-out of linear
rays of light by the object.
Transfinite Principle of Light, Part VII: From Appearance to Knowledge
by Jonathan Tennenbaum
In the latter section of last week’s discussion, I
gave arguments in support of the notion, that light propagates
in straight-line rays. Indeed, by imagining to ourselves that light is a
“something” which propagates outward from each point of a luminous
object, in all directions along straight-line trajectories, we can
account very well for the functioning of the “camera oscura,” for the
main features of the shadows cast by objects, for the changes in
apparent size of objects according to their distance from us (and other
laws of perspective), and many other things. Furthermore, this idea
seems to conform well to our sense experience. Cover a sunlit window by a
black shade, and put some holes in the shade. In the darkened chamber
we can “see” the straight-line rays of light coming through the hole,
just as we can directly “see” the rays coming out of a movie
projector, especially in a smoke or dust-filled room. Let yourself
become so accustomed to this way of conceiving the propagation of
light, that it seems perfectly self-evident.
Now take this notion as a model for {any} sort
of {apparently successful} opinion or belief. What attitude should we
take to it? A critical attitude, of course. But shall we simply reject
the notion of straight-line rays of light out of hand, because it
doesn’t fit with some ideological doctrine or metaphysical prejudice of
ours? Shall we deny that Leonardo da Vinci, Brunelleschi, Kepler, and
other great men drew rays of light as straight lines, or that thousands
of practical activities, such as in surveying, in technical drawing,
etc. seem based on this notion? Shall we simply deny or ignore the
evidence just cited?
Or should we not rather admit that there {does} exist
a very wide-spread phenomenon, an {effect}, which corresponds at
least approximately to what we have described as
“straight-line propagation of light?” If so, then so what? An effect
or phenomenon is one thing; the axiomatic assumptions, in terms of which
we interpret and judge the {significance} of a given array of
phenomena, is something completely different.
We fall into a trap, when we jump from a mere
description of appearances — or a limited, simple hypothesis — to
imputing or superimposing upon the phenomena certain fundamental,
axiomatic qualities of assumption, which are by no means called for by
the phenomena themselves. Watch out when anybody points with his finger
and says: “See this? It proves X,Y,Z.” The expression “evidence of the
senses” is defective, because in reality a process of {judgment} based
on certain assumptions is always implicit, albeit preconsciously, in any
report of such “evidence”.
Indeed, it is common experience (we confront it
daily!) that different people, put in front of one and the same array
of phenomena, draw radically different, even completely
opposite, conclusions. Sometimes we can even witness two or
more individuals in such a debate, pointing to one and the
same phenomenon as “definitive proof” for their mutually
contradictory opinions!
These observations suggest a very big question.
Somebody comes along and challenges us: “If you say your interpretation
of evidence is determined by your axiomatic assumptions, then how could
you ever {know} whether those basic assumptions are true? Aren’t you
caught in a vicious circle? How can you reject self-evident assumptions
on the one hand, and at the same time claim there is no purely
`objective’ evidence which does not involve assumptions of some kind?
You can’t have your cake and eat it, too. If you want to be consistent,
you have to finally make up your mind: either 1) to reject all
fundamental axioms and assumptions, and accept only empirical experience
(sense perceptions) as real, `objective’ knowledge of fact; or 2)
admit that your fundamental axioms and assumptions can never
be scientifically tested or proved in terms of evidence — that they must
therefore either be self-evident, or based on some sort of faith or
belief, as in revealed religion. Or would you agree with my opinion,
that fundamental assumptions are ultimately a matter of arbitrary
choice, so that conflicts of opinion can ultimately only be resolved by
people killing each other?”
Leaving the reader to ponder his or her answer to
this paradox, let’s go back to our concrete case, the
supposed straight-line propagation of light rays.
One person (Newton, for example) draws a light ray,
and thinks of it as a self-evident, axiomatically linear entity,
an entity obeying the formal axioms of “Euclidean geometry.” A second
person (Leonardo Da Vinci, for example) sees the same ray as the trace
of an intrinsically {nonlinear} process. The objective appearance of the
phenomenon is the same. How can we decide between the two
interpretations, the two ways of thinking? Here we get to the issue that
Fresnel and Ampere were addressing, as Fermat and Huygens before them. A
unique experiment signifies more than simply evoking a new “objective
phenomenon” from the Universe. The problem is to evoke and communicate a
true, validated change in how human beings {think} about the Universe.
Let us go back to the time of Fermat. We do not yet
have the demonstrations of interference and diffraction, which
Fresnel used to finally demolish Newton’s linear theory of light. But
we do have an anomaly called {refraction} that was the focus of Fermat’s
elaboration of the {principle of least time}.
Note, for example, that the size and appearance of
the Sun and Moon, and the apparent angular motions of the stars,
are changed when they get near the horizon — a phenomenon which
is commonly explained by the notion, that the rays of light coming from
these objects, are {bent} as they pass obliquely through atmospheric
layers of changing density. Compare this with the bending of light rays
in passing from air to water, or vice-versa, which we can demonstrate in
any classroom. With the aid of a simple apparatus we can make the sharp
change of angle of the rays at the surface of the water clearly
visible. With a bit more effort, we can produce media of varying density
and show clearly how the rays follow {curved} trajectories. Let’s try
to take on a Newtonian with this:
“So you see, light does {not} travel in straight lines!”
“Yes it does, if you do not disturb it. But by
interposing matter, an inhomogenous medium, you deflected the rays from
their natural, straight-line paths.”
“How do you know that straight-line paths are `natural’?”
“If a light ray were allowed to propagate unhindered,
in a pure vacuum or perfectly homogeneous medium, then it
would propagate precisely along a straight line. It is just like
the motion of material bodies in space according to Newton’s first law:
`a material body remains in its state of rest or uniform motion along a
straight line, unless compelled by forces acting upon it to change its
state.’ No one could deny that.”
“Does a `pure vacuum’ exist anywhere in nature? Does a `perfectly homogenous medium’ exist in nature?”
“Well no, of course. There is always a bit of dirt around, or inhomogeneities that disturb the perfectly straight pathways.”
“So the presence of what you call `dirt’ is natural, right?”
“Yes.”
“So then it is natural that light never travels in straight-line paths.”
“Wait a minute. You are mixing everything up. I am talking about the natural propagation of light, quite apart from matter.”
“What do you mean, `quite apart from matter’? Do you
assume that the existence of light is something that can be
separated from the existence of matter?”
“Yes, certainly. The natural state of light is that of light propagating in a Universe that is completely empty of matter.”
“And a completely empty Universe is a natural thing? Do you claim such a think could ever exist?”
“I could imagine one. Sometimes I get that feeling inside my head.”
“Maybe that is because you are not thinking in the real world.”
“Don’t blame me for that. I am a professional physicist.”
“Well then, fill the vacuum in your mind with the
following thought: Light and matter do not exist as separate entities,
nor does matter act to bend rays of light from what you imagine in your
fantasy-universe to be perfectly straight-line rays. Rather, the
existence of what we call matter, the existence of light and the fact
that light never propagates in straight lines — except in mere
appearance — are both interrelated manifestations of the fundamental
curvature of physical space-time, which Fermat began to address with his
principle of least time.”
Transfinite Principle of Light, Part VIII: When Long Is Short
by Bruce Director
It is a continuous source of happiness, for men and
women who have cultivated a capacity for scientific thinking, that
Nature acts along the shortest pathways, and those are always curved.
Not so, however, for the petty and small minded. For them, such
principles are a constant vexation. There is no better example of this,
than Pierre de Fermat’s fight with Descartes.
In 1637, Fermat received a copy of Descartes’
Dioptrics. In that work, Descartes considered light to be an impulse of
particles travelling instantaneously. From this conception, Descartes
presented a mathematical construct of reflection and refraction, by
treating these particles, as if they were hard bodies moving in empty
space. This was an obvious absurdity, since refraction is the phenomena
that occurs when light travels through two different media, not empty
space. Into Galileo’s mathematics of moving bodies, Descartes fitted the
observed phenomena of the refraction and reflection of light.
Fermat found the work deeply flawed, and said so to
Descartes’ epigone Marin Mersenne. First, Fermat said, Descartes erred
by relying solely on mathematical reasoning, which, according to Fermat,
could not lead to the discovery of physical truths. Furthermore, Fermat
attacked Descartes’ mathematics, “of all the infinite ways of dividing
the determination to motion, the author (Descartes) has taken only that
one which serves him for his conclusion; he has thereby accommodated his
means to his end, and we know as little about the subject as we did
before.”
Such insolence from an unknown upstart in Toulouse
offended Descartes no end. He wrote to Mersenne, “… I would be happy to
know what he will say, both about the letter attached to this one, where
I respond to his paper on maxima and minima, and about the one
preceding, where I replied to his demonstration against my Dioptrics.
For I have written the one and the other for him to see, if you please; I
did not even want to name him, so that he will feel less shame at the
errors that I have found there and because my intention is not to insult
anyone but merely to defend myself. And, because I feel that he will
not have failed to vaunt himself to my prejudice in many of his
writings, I think it is appropriate that many people also see my
defense. That is why I ask you not to send them to him without retaining
copies of them. And if, even after this he speaks of wanting to send
you still more papers, I beg of you to ask him to think them out more
carefully than those preceding, otherwise ask you not to accept the
commission of forwarding them to me. For, between you and me, if when he
wants to do me the honor of proposing objections, he does not want to
take more trouble than he did the first time, I should be ashamed if it
were necessary for me to take the trouble to reply to such a small
thing, though I could not honestly avoid it if he knew that you had sent
them to me.”
There the matter rested for 20 years, until, in 1658,
one of Descartes’ zealots, Claude Clerselier, asked Fermat for copies
of his earlier correspondence to include in a volume of Descartes
letters. In the intervening period, Fermat had done his own original
work on light, taking off from the work written by Marin Cureau de la
Chambre. In August 1657, Fermat wrote Cureau, “you and I are largely of
the same mind, and I venture to assure you in advance that if you will
permit me to link a little of my mathematics to your physics, we will
achieve by our common effort a work that will immediately put Mr.
Descartes and all his friends on the defensive.”
Instead of Descartes’ resort to the mythical hard
bodies traveling in empty space, Fermat conceived of light as travelling
at a finite velocity, that changed depending on the density of the
medium through which it travelled. (This was more than 50 years before
Ole Roemer conclusively determined the finite velocity of light, in his
observations of the moons of Jupiter.) But, more importantly, Fermat
proceeded from the standpoint of a universal physical principle, that
nature always acts along the shortest paths. The path, in the case of
refraction, was not the simple geometrical length of the path, but the
path that covered the distance in the least time. “We must still find
the point which accomplishes the process in less time than any other …”
Fermat wrote to Cureau in January 1662.
Upon receiving Fermat’s letter, Clerselier. In a letter dated May 1662, (translated here by Irene Beaudry) Clerselier wrote:
“Do not think that I am answering you today because
you think you have obtained the objective of troubling the peace of the
Cartesians…Permit me just to tell you here the reasons that a zealous
Cartesian could allege to preserve the honor and the right of his
master, but not to give up his own advantage or to give you the
initiative.
“1. The principle that you consider as the foundation
of your demonstration, that is, that nature always acts along the
shortest and simplest pathways, is nothing but a moral principle and not
at all physical, that is, no and could not be the cause of any effect
of nature.
“It is not, because it is not this principle that
makes nature act, but rather, the secret force and the virtue that is in
every thing, that is never determined by such or such an effect of this
principle, but by the force that is in all causes that come together
into one single action, and by the disposition that is actually found in
all bodies upon which this force acts.
“And it could not be otherwise, or else, we would
presume nature to have knowledge: and here, by nature, we mean only this
order and this law established in the world as it is, which acts
without foreknowledge, without choice and by a necessary
determination…..”
Clerselier objects not to Fermat’s discovery that
light travels the path of shortest time, but to the idea that such a
universal principle exists at all. Without a universal principle, there
is no shortest path, only the arbitrariness of empty space.
This is a matter that confronts all of us directly
each day. If civilization’s survival depends on increasing the quality
of human cognition, then the shortest path to that survival is the
seemingly long and curved route of curing the population of their
insanity through mass outreach. Let the petty Clerselier’s take the
short-cuts on that long road of destruction.
Transfinite Principle of Light, Epilogue
LEAST ACTION — PRINCIPLE OF NATURE OR PRINCIPLE OF DISCOVERY?
by Jonathan Tennenbaum
What was it about Fermat’s “principle of least time”
and Leibniz’s generalized “principle of least action” that so upset the
Cartesians and Newtonians, and continues to upset people up to this very
day? In reaction to the beating Fermat and Leibniz administered to
Descartes, in the 18th century a heated and very confused debate was
whipped up concerning so-called “teleological principles in Nature” — a
debate which reached its pinnacle of absurdity when Maupertuis claimed
priority over the long-dead Leibniz in concocting his own, incompetent
version of the least action principle! Behind the diversionary antics of
the buffoon Maupertuis, Euler and Lagrange launched their more
sophisticated attack on Leibniz. Euler and Lagrange worked to eliminate
the self-conscious {principle of discovery} which Leibniz placed at the
center of his conception of the physical universe, and thereby to drive a
wedge between “Naturwissenschaft” and “Geisteswissenschaft.” can find
the trace of these events in our minds, in own struggles to grasp the
central conception of Leibniz’ Monadology, or even the seemingly simple
“principle of least time” put forward by Fermat in the 1630s.
Build a simple apparatus to demonstrate how a beam of
light changes its direction when passing from air into water. Note how
the rate of change of direction itself changes as you change the angle
at which the light beam strikes the surface of the water. When the beam
enters the water perpendicularly to the surface, no change is apparent:
the beam continues onward in the same, perpendicular direction. But as
we gradually tilt the beam away from the perpendicular direction, we
find that the beam is “bent” more and more at the water surface; the
direction of the beam inside the water is steeper, i.e., its angle to
the vertical is smaller than that of the original beam in the air.
(Readers must perform the experiment!). How can we account for the shape
of the pathway, and in particular for the lawful relationship of the
angles which describe the deflection of the beam at the surface of the
water?
Now, the Newtonian-Cartesian way of thinking about
this problem will appear natural and even self-evident to most people,
comparing Fermat’s and Leibniz’s, because the former corresponds to
axioms which have become deeply embedded in our culture. Let’s look at
it for a moment. What, indeed, could be more self-evident, than the idea
that the pathway of the light beam is created by the light itself in
propagating out from the source?
Just so, in Newton’s mechanics, the orbit of a planet
exists only as an imaginary trace of its successive positions; those
positions being created by the planet’s motion. To Newton, the orbit
itself doesn’t exist as an efficient physical entity; what {exists}, at
any given time, is only the planet, its momentary position, its state of
motion and the momentary gravitational force acting upon it from the
Sun. So according to Newton, the fact that a planet traces an elliptical
pathway in the course of its motion is just a mathematical accident, a
derived theorem of the Newtonian theorem-lattice. So, today, the student
is taught to say: “When you solve the equations for motion of the
planet under the force of gravity, it just happens to come out to an
ellipse.”
Imagine the precocious child who, caught with his
hand in the cookie jar, explains: “I couldn’t help it. My body was just
obeying the laws of motion.”
Similarly, according to this way of thinking, the
pathway of the light beam is just the trace of a “something” or large
number of tiny “somethings”, which travel through space from one moment
to the next and one point to the another. They would “naturally” travel
in straight lines, except insofar as some “external forces” deflect them
from a straight-line path. Analyzing the bending of a beam of light
going from air to water in this manner, we divide the process into three
phases: A) the light propagates undisturbed in a straight line through
the air, until B) the beam suddenly “collides” with the water surface,
where the light particles are acted upon by some unknown force causing
them to change their direction of motion, and from that point on C) they
continue travelling in the water in a straight line in the new
direction. This is exactly the thinking of Descartes, Newton, Laplace,
Biot et al.
Not so Fermat! To come onto his footsteps, let us
start from the well-grounded assumption, that Fermat followed Kepler in
these matters. Kepler, as we know, regarded the system of planetary
orbits and the orbits themselves as real and their determination as
{primary} relative to the motions of the planets. An orbit is determined
by a characteristic “curvature in the infinitesimally small”, such that
any however-small interval of planetary motion already expresses the
efficient principle which predetermines the future course of the planet
in that orbit.
Could we say, then, that the light follows a
predetermined {orbit}? Or should we be more cautious and merely propose,
that the pathway of the light beam is merely a visible expression or
characteristic of an {underlying physical process}, whose course is
{predetermined} in the same sense that a planet’s motion is
predetermined by its Keplerian orbit. Either way, we cannot avoid the
implication, that all {three} phases A, B, C defined above, and the
sequence of all three taken together, embody {one and the same}
characteristic infinitesimal curvature!
At this point the formalist-minded will freak out:
“A and C are straight lines, not curved at all;
whereas B is where the beam is “bent”! So how can you talk about the
same curvature?”
Well, maybe you ought to conclude that the
straight-line propagation in A and C is only an {apparently} linear
envelop of a nonlinear process.
“Don’t make things so complicated. After all, so long
as the light is travelling in phase A through the air, before it comes
to the surface of the water, there is no force to divert it; the light
doesn’t yet “know” it is going to hit the water, so it will travel in a
perfect straight line. Or do you suggest, that the light can look ahead
to see the approaching surface of the water?”
Our interlocutor here is trapped in the
Newtonian-Cartesian assumption, that time is a self-evident, linearly
ordered succession of “moments,” where only the preceding moment can
influence the “next” one; just as space were a triply-linear ordering of
“places.” This insistence on a trivial, linear ordering of a supposedly
empty space-time, rejecting the idea of “nonlinearity in the small”, is
key to the freak-out which Fermat caused by his principle of least
time.
To shed more light on this question, let us modify
our experiment slightly: Install a small light source shining in all
directions (e.g., a light bulb) at some position O in the air above the
surface of the water. Now take an arbitrary position X in the water,
which is illuminated by the light. {What is the pathway by which that
result was accomplished?}
We might investigate as follows: Find the positions
Y, both in air and water, at which an opaque object, placed at Y, causes
the illumination of X to be interrupted. (Do the experiment!) We find,
in fact, that those positions lie along a clearly-defined pathway going
from O to X. That pathway in fact runs in an apparent straight-line from
O to a certain location, L, at the surface of the water; and there,
abruptly changing its direction, it continues on in an apparently
straight trajectory to X. We can also verify, that if we now replace the
light bulb at O by a device which produces a directed beam, and point
the beam in the direction toward L, then it will continue along the
entire pathway we just determined, and illuminate X. If we point the
beam in a different direction, then (leaving aside extraneous
reflections and so forth), it does {not} arrive at X. Our conclusion:
this is the {unique} trajectory, by which light, emitted at O, can and
does arrive at X.
Now what do we do, striving to follow Kepler in this
matter? Instead of trying to concoct some Newtonian-like “law of motion”
by which the light supposedly proceeds blindly, step-by-step from one
moment to the next, consider instead at the {space-time process as a
whole}. How is it that a unique trajectory (or “tube of trajectories”
appearing to our senses as a single one) is determined, among all other
conceivable other paths running from O to X, as the one which is
actually {realized} by light? What is the sufficient and necessary
reason? Evidently, not some property of light in and of itself. Ah!
Don’t forget the rest of the Universe! Don’t forget that our experiment
is part of the ongoing {history of the Universe}, and what we call
“light” is just a localized manifestation of the {entire Universe}
acting upon itself in that specific historical interval. If so, then
shall we not regard the observed pathway of light as a {projection} of
the Universe’s ongoing historical orbit, its “world line”?
Now, perhaps, we can begin to appreciate the
significance of the Fermat-Leibniz principle and the freak-out it evoked
among the followers of Aristotle.
Don’t Vote for Anyone Who Doesn’t Know Kepler
by Bruce Director
The foolishness of relying on pure mathematical
models for the design and production of automobiles, nuclear weapons, or
any other physical device, would be obvious to anyone with a minimal
level of knowledge of the discoveries of Cusa, Kepler, Leibniz, Gauss,
Riemann, et al. Unfortunately, such knowledge is virtually non-existent
among the leaders of governments and businesses, today, as the frauds of
the Mercedes A-class and the Cox report amply demonstrate. Fortunately,
those who study the writings of Lyndon LaRouche need not suffer the
afflictions of the aforementioned Lilliputians.
Take the case of Kepler’s discovery of the physical
characteristics of planetary motion enunciated in his New Astronomy. As
we demonstrate below, through their own words, Kepler demolished, nearly
400 years ago, the mathematical modelers of his day.
In the introduction of that work Kepler states:
“The reader should be aware that there are two
schools of thought among astronomers, one distinguished by its chief,
Ptolemy and the assent of the large majority of the ancients, and the
other attributed to more recent proponents, although it is the most
ancient. The former treats the individual planets separately and assigns
cause to the motions of each in its own orb, while the latter relates
the planets to one another, and deduces from a single common cause those
characteristics which are found to be common to their motions. The
latter school is again subdivided. Copernicus, with Aristarchus or
remotest antiquity, ascribes to the translational motion of our home,
the earth, the cause of the planets appearing stationary and retrograde.
Tycho Brahe, on the other hand, ascribes this cause to the sun, in
whose vicinity he says the eccentric circles of all five planets are
connected as if by a kind of knot (not physical, of course, but only
quantitative). Further, he says that this knot, as it were, revolves
about the motionless earth, along with the solar body.
For each of these three opinions concerning the world
there are several other peculiarities which themselves also serve to
distinguish these schools, but these peculiarities can each be easily
altered and amended in such a way that, so far as astronomy, or the
celestial appearances, are concerned, THE THREE OPINIONS ARE FOR
PRACTICAL PURPOSES EQUIVALENT TO A HAIR’S BREADTH, AND PRODUCE THE SAME
RESULT.”
What Kepler is referring to is the fact that the
observed motions of the stars, planets, sun, and moon, can be calculated
equally by the three radically different mathematical models of
Ptolemy, Copernicus, and Tycho Brahe.
The most elementary observations of the motions of
heavenly bodies reveal two distinct motions. The so-called first motion,
is the uniform daily movement across the sky of the sun, moon, stars,
and planets from east to west. (Don’t take my word for it though. Go out
an look for yourself!) The so-called second motion, is movement from
west to east of the planets, sun, and moon, with respect to the fixed
stars, over longer periods of time. Upon careful observation, this
second motion is seen to be non-uniform. The planets, moon, and sun move
slower and faster at different stages in the second motion, and, the
planets, at times appear to stop and move backward with respect to the
stars, at different stages in the course of the second motion.
The observation of these two motions is not the stuff
of casual sense experience, but a characteristic of human reason. In
the first chapter of the New Astronomy, Kepler says:
“The testimony of the ages confirms that the motions
of the planets are orbicular. It is an immediate presumption of reason,
reflected in experience, that their gyrations are perfect circles. For
among figures it is circles, and among bodies the heavens, that are
considered the most perfect. However, when experience is seen to teach
something different to those who pay careful attention, namely, that the
planets deviate from a simple circular pattern, it gives rise to a
powerful sense of wonder, which at length drives men to look into
causes.”
Neither Ptolemy, Copernicus, nor Tycho Brahe,
however, ever laid claim to that “powerful sense of wonder,” of which
Kepler speaks.
In the opening of the Almagast, Ptolemy says, “Those
who have been true philosophers, Syrus, seem to me to have very wisely
separated the theoretical part of philosophy from the practical…. For
indeed Aristotle quite properly divides also the theoretical into three
immediate genera; the physical, the mathematical, and the theological.”
Ptolemy goes on to say that man can know nothing certain of the theological nor physical:
“The theological because it is in no way phenomenal
and attainable, but the physical because its matter is unstable and
obscure, so that for this reason philosophers could never hope to agree
on them; and meditating that only the mathematical, if approached
enquiringly, would give its practitioners certain and trustworthy
knowledge with demonstration both arithmetic and geometric resulting
from indisputable procedures, we were led to cultivate most particularly
as far as lay in our power this theoretical discipline.”
Having dispensed with any pretense that his theory
had any physical reality, Ptolemy developed his now infamous system of
intricate earth-centered cycles, eccentrics, and epicylces to
mathematically calculate the positions of the planets, stars, moon, and
sun, over time. While Ptolemy’s system can truthfully be called a fraud,
the bigger frauds are those, who until this day, propounded this
mathematical system, as physical hypothesis.
Copernicus replaced Ptolemy’s complicated system,
with the simpler and more beautiful sun-centered system, where the earth
and the planets move in perfect circles about a stationary sun.
Nevertheless, this was a purely mathematical model. In the Introduction
to his “On the Revolutions of the Heavenly Spheres,” Copernicus says:
“For it is the job of the astronomer to use
painstaking and skilled observation in gathering together the history of
the celestial movements, and then — since he cannot by any line of
reasoning reach the true causes of these movements — to think up or
construct whatever causes of hypotheses he pleases such that, by the
assumption of these causes, those same movements can be calculated from
the principles of geometry for the past and for the future. This artist
is markedly outstanding in both of these respects; for it is not
necessary that these hypotheses should be true, or even probable; but it
is enough if they provide a calculus which fits the observations….”
As Kepler describes above, Tycho Brahe’s mathematical
model had all the planets revolving around the sun, and this knot
moving around a stationary Earth. But as Kepler says, Brahe’s system is
not physical, but merely quantitative.
Since the systems of Ptolemy, Copernicus, and Brahe
are all mathematically equivalent, and none lay claim to any physical
reality, how can one distinguish which one is true? Only in the domain
of physical measurement. This is precisely the revolutionary discovery
that Kepler makes, following the path laid out by his mentor, Nicholas
of Cusa.
Again, in the Introduction of the New Astronomy Kepler continues:
“My aim in the present work is chiefly to reform
astronomical theory (especially of the motion of Mars) in all three
forms of hypotheses, so that our computations from the tables correspond
to the celestial phenomena. Hitherto, it has not been possible to do
this with sufficient certainty. In fact, in August 1608, Mars was a
little less than four degrees beyond the position given by calculation
from the Prutenic tables. In August and September of 1593 this error was
a little less than five degrees, while in my new calculation the error
is entirely suppressed.
“… The eventual result of this consideration is the
formulation of very clear arguments showing that only Copernicus’s
opinion concerning the world (with a few small changes) is true, that
the other two accounts are false, and so on.
“Indeed, all things are so interconnected, involved,
and intertwined with one another that after trying many different
approaches to the reform of astronomical calculations, some well trodden
by the ancients and others constructed in emulation of them and by
their example, none other could succeed than the one founded upon
motions’ physical causes themselves, which I establish in this work.”
Readers of previous pedagogical discussions, and the
Fidelio article on Gauss’ determination of the orbit of Ceres for will
know something of Kepler’s discoveries. Isn’t it time we raised the
level of thinking of the citizenry, so that they would demand such
knowledge of their elected officials and designers of automobiles?
Newton’s World: No Love, Just Copulation
by Bruce Director
Several weeks ago we presented, in their own words, a
demonstration that Kepler’s determination of the principles of
planetary motion, demolished the Aristotelian methods of “mathematical
modeling,” adhered to by Ptolemy, Brahe, and Copernicus. This week, we
follow up with a further consequence of that demonstration: that all
subsequent scientific inquiry that did not follow Kepler’s method was
not just wrong, but fraudulent.
As presented in the previous discussion, Kepler, in
the “New Astronomy,” set out to completely revolutionize astronomy (and
all science) by putting it on a foundation of physical principles. As
they testified themselves, Ptolemy, Copernicus, and Brahe were concerned
only with developing formal descriptions of the observed motions of the
planets. Truthfulness was limited to the logical-deductive consistency
of those descriptions, and the consistency of those descriptions with
observations. As Kepler stated, all three descriptions were equivalent
“within a hair’s breadth,” but all three deviated from the observations
by an amount greater than the margin of error associated with the
capacity of the measuring instruments used for those observations.
The specific observed phenomena that concerned
Kepler, Ptolemy, Brahe, and Copernicus, were the two unequal motions of
the planets, observed by humankind since ancient times.
The first “inequality” was the observed non-uniform
motion of the planets, in a cycle, from west to east, through the
constellations of the zodiac. Each planet made this circuit in different
lengths of time, and, as each travelled through its cycle, it appeared
to move faster through certain constellations than others, that is,
traversing a greater angular arc in the sky for a given time interval,
depending on which constellation of the zodiac it was moving through.
The second “inequality” was the so-called
“retrograde” motion, when the planet appeared to move from east to west
through the zodiac. This was observed when the planet was rising in the
east just as the sun set in the west. This configuration was known as
“opposition.”
Ptolemy, Copernicus, and Brahe all described these
phenomena with radically different geometrical constructions, but all
held firm to the belief that these apparent non-uniform motions, were
just that; “apparent,” not real. All three believed that the “true”
motion of the planet had to be uniform circular motion. The two
“inequalities” were simply optical illusions, owing to the complicated
concoction of circles, that each had created.
Kepler took an entirely different approach:
“The testimony of the ages confirms that the motions
of the planets are orbicular. It is an immediate presumption of reason,
reflected in experience, that their gyrations are perfect circles. For
among figures it is circles, and among bodies the heavens, that are
considered the most perfect. However, when experience is seen to teach
something different to those who pay careful attention, namely, that the
planets deviate from simple circular path, it gives rise to a powerful
sense of wonder, which at length drives men to look into causes.”
Driven by this “powerful sense of wonder,” Kepler
looked into the causes. First he established the equality of the
Ptolemaic, Brahean, and Copernican models. Then Kepler abandoned the
false belief of embedded in all three models, that the “true” motion was
uniform circular motion, and the non-uniform motion was simply
apparent. Instead, Kepler took the apparent motion as the true. That is,
that the planets actually did move non-uniformly. Once this conceptual
bridge had been crossed, the geometrical construction of the planets
moving on an orbit, about an eccentric and sweeping out equal areas in
equal times, proceeded from the physical measurements themselves. The
power that moved the planet, according to Kepler, had to be located at
that eccentric.
Under this conception, the planet’s distance from the
eccentric about which it was moving, varied continuously. That is, as
the planet moved about it’s orbit, the distance from the planet to the
eccentric was always getting longer or shorter, and consequently, the
effect of the moving power was increasing as the distance decreased and
diminishing as the distance increased. Then Kepler demonstrated that the
moving power resided in the Sun, which was located at the eccentric
point. When this conception was again tested against the physical
measurements, Kepler refined his construction to an elliptical orbit
with the Sun located at one of the foci. Later, Kepler demonstrated a
third principle of planetary motion between the periodic times and the
size of the orbit, mischaracterized today as his “Third Law.” (The
reader can consult chapter’s 5-8 in the Summer 1998 Fidelio article on
how Gauss Determined the Orbit of Ceres).
How absolutely banal, sterile, and fraudulent, is
therefore, Newton’s resort to action at a distance according to the
inverse square law. This is ass backwards. For Newton, the planetary
motion is reduced to a copulation along the straight line connecting the
planet to the Sun. The physical space time curvature of Kepler is
eliminated. Only straight-line copulation remains.
So fraudulent is Newton’s view, that according to Riemann:
“Newton says: `That gravity should be innate,
inherent, and essential to matter, so that one body can act upon another
at a distance through a vacuum, without the mediation of anything else,
by and through which their action and force may be conveyed from one to
another, is to me so great an absurdity, that I believe no man who has
in philosophical matters a competent faculty of thinking can ever fall
into it.’ See the third letter to Bently.”
Yet people continue to adhere to the false beliefs
that underlie Ptolemy and Newton. With their asses facing the students,
professors throughout the world present Newton’s straight-line
copulation as the basis for planetary motion, despite the final burial
of Newton by Gauss with his discovery of the orbit of Ceres. In his
{Theoria Motus} Gauss says:
“The laws above stated differ from those discovered
by our own Kepler in no other respect than this, that they are given in a
form applicable to all kinds of conic sections … If we regard these
laws as phenomena derived from innumerable and indubitable observations,
geometry shows what action ought in consequence to be exerted upon
bodies moving about the sun in order that these phenomena may be
continually produced. In this way it is found that the action of the sun
upon the bodies moving about it is exerted {as if} an attractive force,
the intensity of which is reciprocally proportional to the square of
the distance should urge the bodies towards the center of the sun.
(emphasis supplied.)
Turn again to Kepler from the introduction of the {Mysterium Cosmographicum}:
“Though why is it necessary to reckon the value of
divine things in cash like victuals? Or what use, I ask, is knowledge of
the things of Nature to a hungry belly, what use is the whole of the
rest of astronomy? Yet men of sense do not listen to the barbarism which
clamors for these studies to be abandoned on that account. We accept
painters, who delight our eyes, musicians, who delight our ears, though
they bring no profit to our business. And the pleasure which is drawn
from the work of each of these is considered not only civilized, but
even honorable. Then how uncivilized, how foolish, to grudge the mind
its own honorable pleasure, and not the eyes and ears. It is a denial of
the nature of things to deny these recreations. For would that
excellent Creator, who has introduced nothing into Nature without
thoroughly foreseeing not only its necessity but its beauty and power to
delight, have left only the mind of Man, the lord of all Nature made in
his own image, without any delight? Rather, as we do not ask what hope
of gain makes a little bird warble, since we know that it takes delight
in singing because it is for that very singing that the bird was made,
so there is no need to ask why the human mind undertakes such toil in
seeking out these secrets of the heavens. For the reason why the mind
was joined to the senses by our Maker is not only so that man should
maintain himself, which many species of living things can do far more
cleverly with the aid of even an irrational mind, but also so that from
those things which we perceive with our eyes to exist we should strive
towards the causes of their being and becoming, although we should get
nothing else useful from them. And just as other animals, and the human
body, are sustained by food and drink, so the very spirit of Man, which
is something distinct from Man, is nourished, is increased, and in sa
sense grows up on this diet for these things. Therefore as by the
providence of nature nourishment is never lacking for living things, wo
we can say with justice that the reason why there is such great variety
in things and treasuries so well concealed in the fabric of the heavens,
is so that fresh nourishment should never be lacking for the human mind
and it should never disdain it as stale, nor be inactive, but should
have in this universe an inexhaustible workshop in which to busy
itself.”
Newton’s Gore
by Bruce Director
After reading the past two pedagogical discussions on
this subject, there should be no doubt in your mind that Newton was a
fraud. The question remains: why does Newton work? Not, why do Newton’s
theories work — they don’t — but why does the fraud work?
The populist conspiracy theorist, or anyone else
prone to superficial thinking might conclude that the fraud works
through the suppression of Kepler. True, many of Kepler’s writings have
been obscured over the ages, not widely published or translated, nor
taught as original sources in secondary schools or universities.
Nevertheless, they are available for any thinking person to obtain and
study. Furthermore, the physical anomalies, from which the principles on
which Kepler’s discoveries are based can be observed any night by
anybody from any where on Earth.
No! it is not a lack of information, that keeps the
fraud of Newton alive. Nor is the fraud perpetrated by controlling the
purse strings of professors and scientists, or the raw political power
of the British Royal Society, although that certainly is an element.
None of that explains why generation after generation, Newton’s fraud is
accepted willingly, to the point where victims of this fraud will
hysterically defend it when challenged.
There is something more sinister involved, a
vulnerability inside the mind of these wretched creatures that leads
them to prefer the straight-line copulative world of Newton; to desire a
world uncomplicated by the primacy of curvilinear action; and to yearn
for a universe free of disturbing discontinuities.
To find this flaw, start with the report published in
the May 31, 1999 briefing, quoting St. Augustine’s report from his
Confessions of how his friend was drawn, against his better judgement,
into lusting for the savagery of the Roman Circus. This begins to
approximate the mindset that draws the unsuspecting dupe into Newton’s
world.
Or, turn to the insightful allegory “Mellonta Tauta” of Edgar Allen Poe, whose protagonist reports:
“Do you know that it is not more than a thousand
years ago, since the metaphysicians consented to relieve the people of
the singular fancy that there existed but {two possible roads for the
attainment of Truth!} Believe it if you can! It appears that long, long
ago, in the night of Time, there lived a Turkish philosopher (or Hindoo
possibly) called Aries Tottle. This person introduced, or at all events
propagated what was termed the deductive or {a priori} mode of
investigation. He started with what he maintained to be axioms or
`self-evident truths,’ and thence proceeded `logically’ to results. His
greatest disciples were one Neuclid and one Cant. Well, Aries Tottle
flourished supreme until the advent of one Hog, surnamed the `Ettrick
Shepherd,’ who preached an entirely different system, which he called
the {a posteriori} or {inductive}. His plan referred altogether to
Sensation. He proceeded by observing, analyzing and classifying facts —
{instantiae naturae}, as they were affectedly called — into general
laws. Aries Tottle’s mode, in a word, was based on {noumena}; Hog’s on
{phenomena}. Well, so great was the admiration excited by this latter
system that, at its first introduction, Aries Tottle fell into
disrepute; but finally he recovered ground, and was permitted to divide
the realm of Truth with his more modern rival. The savants now
maintained that the Aristotelian and Baconian roads were the sole
possible avenues to knowledge. `Baconian,’ you must know, was an
adjective invented as equivalent to Hog-ian and more euphonious and
dignified.
“Now, my dear friend, I do assure you, most
positively, that I represent this matter fairly, on the soundest
authority; and you can easily understand how a notion so absurd on its
very face must have operated to retard the progress of all true
knowledge — which makes its advances almost invariably by intuitive
bounds. The ancient idea confined investigation to {crawling} and for
hundreds of years so great was the infatuation about Hog especially,
that a virtual end was put to all thinking properly so called. No man
dared utter a truth for which he felt himself indebted to his Soul
alone. It mattered not whether the truth was even {demonstrably} a
truth, for the bullet-headed {savants} of the time regarded only {the
road} by which he had attained it. They would not even look at the end.
`Let us see the means,’ they cried, `the means!’ If, upon investigation
of the means, it was found to come neither under the category Aries
(that is to say Ram) or under the category Hog, why then the {savants}
went no farther, but pronounced the `theorist’ a fool, and would have
nothing to do with him or his truth….
“Now I do not complain of these ancients so much
because their logic is, by their own showing, utterly baseless,
worthless and fantastic altogether, as because of their pompous and
imbecile proscription of all {other} roads of Truth, of all {other}
means for its attainment than the two preposterous paths — the one of
creeping and the one of crawling — to {which} they have dared to confine
the Soul that loves nothing so well as to {soar}.
“By the by, my dear friend, do you not think it would
have puzzled these ancient dogmaticians to have determined by {which}
of their two roads it was that the most important and most sublime of
{all} their truths was, in effect, attained? I mean the truth of
Gravitation. Newton owed it to Kepler. Kepler admitted that his three
laws were {guessed at} — these three laws of all laws which led the
great Inglitch mathematician to his principle, the basis of all physical
principle — to go behind which we must enter the Kingdom of
Metaphysics. Kepler guessed — that is to say, {imagined}. He was
essentially a `theorist’ — that word now of so much sanctity, formerly
an epithet of contempt. Would it not have puzzled these old moles, too,
to have explained by which of the two `roads’ a cryptographist unriddles
a cryptograph of more than usual secrecy, or by which of the two roads
Champollion directed mankind to those enduring and almost innumerable
truths which resulted from his deciphering the Hieroglyphics?”
For the moment, no more need be said.
Incommensurability and {Analysis Situs}, Part I
by Jonathan Tennenbaum
The issue of analysis situs becomes
unavoidable, when we are confronted with a relationship of two or more
entities A and B (for example, two historical events or principles of
experimental physics), which do not admit of any simple consistency or
comparability, i.e., such that the concepts and assumptions, underlying
our notion of “A,” are formally incompatible with those underlying “B.”
In the case where the relationship between A and B is undeniably a
causally efficient one, we have no rational choice, but to admit the
existence of a higher principle of lawful relationship (a “One”)
situated beyond the framework provided by A and B as originally
understood “in and of themselves.”
Exactly the stubborn, “dumbed down” refusal to accept the existence of such higher principles of analysis situs,
lies at the heart of the chronic mental disease of our age. That
includes, not least of all, the Baby Boomer’s typical penchant for
“least common denominator” approaches to so-called “practical politics.”
Antidotes are urgently required.
An elementary access to this problem, as well as a hint at analysis situsitself,
is provided by the ancient discovery–attributed to the school of
Pythagoras–of the relative incommensurability of the diagonal and side
of a square. This discovery, a precursor to Nicolaus of Cusa’s “Docta
Ignorantia,” could with good reason be characterized as a fundamental
pillar of civilization, which ought to be in the possession of every
citizen; indeed, the rudiments thereof could readily be taught to school
children. Yet, NOWADAYS there are probably only a HANDFUL of people in
the whole world, who approach having an adequate understanding of it.
In order to appreciate the Pythagorean discovery, it
were better to first elaborate a lower-order hypothesis concerning
measurement and proportion, and then see why it is necessary to abandon
that hypothesis at a certain well-defined point, in favor of a
higher-order conception. The hypothesis in question is connected with
the origin of what might be called “lower arithmetic”–as contrasted to
Gauss’ “higher (geometrical) arithmetic”–which however is not to deny
the eminent usefulness and even indispensibility of the lower form
within a certain, strictly delimited domain. On the other hand, the
discoveries of the Pythagorean school put an end to what might otherwise
have become a debilitating intoxication with simple, linear arithmetic,
one not unsimilar to the present-day obsession with formal algebra and
“information theory.”
Linear measure
Already in ancient times, it became traditional to
distinguish between three species (or degrees of extension) of geometry
within Euclidean geometry itself: so-called linear, plane, and solid
geometry. The phenomenon of “incommensurability” bursts most clearly
into view, when we attempt to carry over certain notions of measurement
and proportion, apparently reasonable and adequate for the comparison of
lengths along a line, into the doubly- and triply-extended domains of
plane and solid geometry. Actually, the problem is already present in
the lower domain; but it takes the transition to the higher domains to
“smoke it out” and render it fully intelligible.
The commonplace notion of measurement and proportion,
is based on the hypothesis that there exists some basic element or
“unit,” common to the entities compared, out of which each of the
entities can be derived by some formally describable procedure. In the
linear domain of Euclidean geometry–which, incidentally, presupposes the
hypothesis, that length is independent of position–this approach to
measurement unfolds on the basis of three principles:
First, given two line segments, we preliminarily
examine their relations of position, i.e., whether they are disjoint,
overlap, or one is contained in the other. Secondly, we superimpose
them, by means of so-called “rigid motion” (again, an hypothesis!), to
ascertain their relation in terms of “equal length,” “shorter,” or
“longer.” And thirdly, we extend or multiply a given line segment, by
adjoining to it reproductions of itself, i.e., segments of equal length.
By combining these principles, we arrive at such
propositions as “segment B is equal in length to (or shorter or longer
than) two times segment A,” or such more complicated cases as “three
times segment B is equal to (or shorter or longer than) five times
segment A,” and so forth. [Figure 1.] In the case, where a segment B is
determined to be equivalent (in length) to a multiple of segment A, it
became customary to say, that “A exactly divides (or measures) B,” and
to express the relationship by supplying the exact number of times that A
must be replicated, in order to fill out a length equivalent to B.
Where such a simple relationship does not obtain between A and B, it
would be natural to direct our efforts toward finding a smaller segment
C, which would exactly divide A and exactly divide B at same time
(commensurability!). In case we succeed, the ratio of the corresponding
multiples of C, required to produce the lengths of A and B respectively,
would seem to perfectly express the relationship between A and B in
terms of length. So, the proposition “A is three-fifths of B” or “A is
to B as three is to five” would express the case, where we had
determined, that A = 3C and B = 5C for some common “unit” C. [Figure 2.]
– The paradox of `Euclid’s algorithm’ –
HOW, a practically-minded person would probably ask,
might we discover a suitable common divisor C for any given segments A
and B? It were natural to first try the shorter of the two lengths, say
A, and to seek the largest multiple of A which is not larger than B. If
that multiple happens to exactly equal B, we are finished, and can take C
= A. Otherwise, we shall have to deal with the occurrence of a
“remainder” in the form of a segment R, shorter than A, by which the
indicated multiple of A falls short of B’s length. One possible reaction
to this would be, to divide A in half, and then if necessary once again
in half, and so on, in the hope that one of the resulting series of
sub-segments might be found to exactly divide B. Those skillful in these
matters will see, however, why such an approach must often lead to a
dead end–as for example when the lengths of A and B happen to stand in
the ratio 3 to 5, in which case successive halving of A or B could never
produce a common divisor. [Figure 3.]
A much more successful approach, which (at this stage
of the problem) represents a “least action” solution, became known in
later times as “Euclid’s algorithm”: In case the shorter segment, A,
does not divide B exactly, we take as next “candidate” the remainder R
itself. If R divides A exactly, then R is evidently a common divisor of
both A and B. Otherwise, take the remainder of A upon division by R–call
it R’–as the next “candidate.” Again, if R’ exactly divides R, then (by
working the series of steps backwards) R’ will also divide A and B. If
not, we carry the process another step further, producing a new, even
smaller remainder R”, and so forth. This approach has the great
advantage that, ASSUMING A COMMON DIVISOR of A and B ACTUALLY EXISTS, we
shall certainly find one. In such a case, in fact, as the reader can
confirm by direct experiments, the indicated process leads with rather
extraordinary rapidity, to the greatest common divisor of the segments A
and B. [Figure 4.]
The discussion so far, however, leaves us with a
rather considerable paradox. For the case, that there exists a segment
dividing A and B exactly, the indicated approach to measurement and
proportion, provides us with an efficient means to find the largest such
common divisor, as well as to derive an EXACT characterization of the
relationship of A to B in terms of a ratio of whole numbers. At the same
time, however, some of us might have caught a glimpse of a potential
“disaster” looming on the horizon: What if the “Euclid algorithm,”
sketched above, fails to come to an end? It were at least conceivable,
that for some pairs A, B, the successive remainders R, R’, R”…, while
rapidly becoming smaller and smaller, might each differ sensibly from
zero.
Within the limits of the ideas we have developed up
to this point, we find the means neither to rule out such a “disaster”
(“bad infinity”), nor to devise a unique experiment which might
demonstrate the failure of “Euclid’s algorithm,” while at the same time
providing a superior approach.
Evidently, it were folly to search for an answer
within the “virtual reality” of linear Euclidean geometry per se. We
need a flanking maneuver, to catapult the whole matter into a higher
domain. [To be continued.]
EXCERPTS FROM A REPLY BY JONATHAN TENNENBAUM TO QUESTIONS ON HIS PEDAGOGICAL DISCUSSIONS
Dear Reader,
Pardon my delay in responding to your queries concerning the pedagogical discussions.
Let me first address the last point in your letter, which is the most significant. I mean the following passage:
“On the notion that the rate of change, or change in
the rate of change is alien to Euclid, needing to be imported from our
higher vantage point: A number of us just do not see the revolutionary
‘axiom-busting’ nature of this concept…”
Judging from your report, the problem which came to
the surface during your discussions, is fundamental. I am very happy
that the problem surfaced, although it tells me that my pedagogical
tactic failed, at least in some cases. No matter. We often learn more
from our failures, than from our successes!
What I think is going wrong, in part, is that many
(probably most) people haven’t broken through yet, or are still
resisting, to grasp in a really SENSUOUS way, what Lyn is trying to get
at with his discussions of theorem-lattices and changes of axioms.
People have a kind of abstract understanding of these matters, which
they can present formally, can cite examples and so on, and even apply
the concept in a certain way; but it’s still skin-deep, somewhat
superficial learning. Above all, there is an emotional problem, a
problem of INDIFFERENTISM or “decoupling” of mental activity from
passion, which was induced from very early on in school, in university
studies, and actually by our whole cultural environment. All of us of
our generation — I would not exclude myself — have to struggle with this
problem to one extent or another.
In order to function properly, the pedagogical
discussions must be composed and read, not like sections of a textbook,
but rather as miniature DRAMAS of the most rigorous sort. A drama
involves powerful emotion. It is not just an “intellectual exercise.” In
a well-composed and well-acted tragedy, the achievement of the desired
effect on the audience, requires, that the individuals in the audience
actually TAKE INTO THEIR OWN MINDS, by a powerful sort of “resonance”
(empathy) the thought-processes projected by the dramatist with the aid
of the characters. Under such conditions, the dramatist can operate
DIRECTLY on the inner mental processes of the audience.
The simplest form of pedagogical discussion presents a
TYPE of physically-demonstrable, valid transition from a hypothesis
“A,” to a superior hypothesis “B,” such that the theorem-lattices,
corresponding to “A” and “B” respectively, are separated from each other
by an absolute mathematical discontinuity. In other words, although “B”
subsumes (albeit in reworked form) that aspect of “A” which has not
been invalidated by the experimental discovery, there is no way to get
from “A” to “B” by deductive methods.
In some cases, an experimental demonstration directly
refutes an explicit prediction of “A.” Thus, we demonstrate, that an
event, which a theorem of “A” says must occur in a certain way, does NOT
occur in that way. But very often, the most prominent characteristic of
an experimental demonstration, is that it reveals an implicit
LIMITATION in the original hypothesis “A,” rather than, so to speak, an
explicit error. Something is demonstrated to occur in the real universe,
which COULD NOT EXIST in the “mental world” circumscribed by hypothesis
“A.” It is not necessary, that the event AS SUCH be EXPLICITLY
FORBIDDEN by “A.” In fact, “A” will generally have NO CONCEPT for the
event: “A” cannot account for its existence; it presents an insoluable
paradox; it is “unimaginable.” And yet, the human mind (though perhaps
not the mind of a radical positivist) is forced to acknowledge its
existence as experimentally demonstrated.
Actually, the two cases are not so different, as
might appear at first glance, if we understand the concept of
“hypothesis” to mean, not just an assumption about this or that
specialized area, but (at least, implicitly) a WAY OF THINKING about the
ENTIRETY OF THE UNIVERSE. For, THE MIND IS ONE. In fact, our mind tends
to extrapolate or “project” the underlying limitations of a given
hypothesis, upon the entirety of the universe, in such a way that those
limitations become “invisible” to us. So, the fish considers the
fishbowl to be the entire universe, until something is demonstrated to
exist outside the fishbowl. Only then, do the limits of the fishbowl
become apparent.
I suspect that people miss the Earth-shaking
implications of the pedagogical demonstration in question, because they
are holding the hypotheses involved safely at arm’s length, rather than
letting them really sink in. In other words, not really getting
involved. You really have to become accustomed to the mental world of
hypothesis “A” for a certain time, internalizing the corresponding mode
of thinking, in order then to experience FROM “INSIDE,” so-to-speak, a
crucial moment of physically demonstrable FAILURE of the mode. This
requires a kind of mental dexterity and playfulness, to “forget” or
“unlearn” the existence of the superior hypothesis “B” (in this case,
connected with the necessary introduction of notions of “rate of
change”), even though that has long become a part of our general
culture. We have to use our imagination in order to place ourselves
mentally, in a sense, back into the period BEFORE the discovery in
question was made. In the same way, we should be able to imagine, on the
basis of higher hypothesis, a future world embodying experimental
refutations of hypotheses which we today regard as self-evident.
Were the Greeks and others, who developed their
physical science in terms of “Euclidean geometry,” all stupid or evil?
Certainly not! Although an adequate history has yet to be assembled, it
is certain, that what we now call “Euclidean geometry” BEGAN as a series
of REVOLUTIONARY BREAKTHROUGHS in physics, associated with the
discovery and elaboration of certain general principles of CONSTRUCTION.
The highest point of this development, as stressed by Kepler, was
embodied in the treatment of the five regular solids, formally
summarized by Euclid in the famous Tenth Book of Euclid’s {Elements}.
The Greek constructive geometry, reworked by Euclid as a prototype of a
formal theorem-lattice, embodied a kind of technology of thinking, far
superior to what had existed prior to that (for example in the Egyptian
or ancient Chinese science, as far as we know).
Thus, it were useful, before proceeding to my
pedagogical discussion of the circle, to first get back into the mode of
Euclidean geometry. For example by doing constructions such as:
constructing perpendiculars and parallels, constructing divisions of the
circle (equilateral triangle, square, pentagon, hexagon), constructing
the golden section, bisecting any given angle, dividing a line segment
into any given number of equal segments, constructing the tangent to a
circle at any point, constructing a demonstration of Pythagoras’
theorem, etc. Allow yourselves to get into the “mind set” of this type
of approach to problems. This is the same thing I tried to do in the
earlier discussion of incommensurability, where I introduced the
“Euclid’s algorithm” in one-dimensional geometry, not so much its own
sake, but as characteristic of a kind of approach to the problem of
measurement.
Of course, the concept of CHANGE is central to the
every positive development of human civilization. The constructive
geometry of the Greeks itself represents an attempt to deal with that.
Of course, the notion of change and rate of change is “always there,” in
a certain way, within higher hypothesis (see Plato’s {Timaeus}, for
example). But the elaboration of a constructive geometry based
explicitly on the notion of variable rate of change, came much later.
Just compare the physics of Archimedes, with the physics launched in
Nicolaus of Cusa’s {Docta Ignorantia} and brought to full development
through the non-algebraic function theory of Huygens, Leibniz and
Bernoulli. The turning-point, as far as we can see, came with the
revolutionary shift in conception, embodied in Nicolaus of Cusa’s
treatment of the circle and related topics, relative to the Euclidean
approach of Archimedes.
Thus, you will not find the notion of “variable rate
of change,” as that is understood by Leibniz, in Euclidean geometry.
It’s not there. It is certainly implicit in the higher hypothesis
guiding the development of Greek geometry, in Plato and so forth; but it
was not yet actualized as an elaborated hypothesis. Thus, there is a
constant TENSION between hypothesis and higher hypothesis, which
constantly drives knowledge forward, employing a succession of unique
experiments.
I hope these remarks will be helpful to you and your colleagues….
Concerning your reference to “solving” equations for
the ratio of diagonal to side of an isoceles triangle, I would caution
as follows: When an algebraicist says “the square root of two,” he is
usually only slapping a label onto an UNFILLED GAP in his knowledge. He
has not thereby developed a CONCEPT. Whereas by contrast, the
paradoxical result of the geometrical construction evokes — in the mode
of metaphor, and not merely pasting formal labels on things — an actual
concept of a precisely-characterized, yet linearly inexpressible
magnitude.
Concerning your query on light, I intend to develop
some pedagogical discussions on exactly this subject, which requires a
certain amount of elaboration. But from the way you expressed your
question, I suspect that people have been boxing themselves a bit into a
too constricted, literal, “mathematical” way of thinking about these
matters. What is worthwhile to reflect about in a broad way — without
necessarily expecting to come up with a “final answer” — is the
question: What kind of Universe are we living in, in which such
phenomena as refraction and diffraction of light can take place? Then,
compare that with the “mental world” associated with the Euclidean
approach to geometry.
Keep up the good work. I will be happy to help if you have any further queries.
Best wishes,
Jonathan Tennenbaum
Incommensurability and Analysis Situs Pedagogical Discussion Part II: Experimental demonstration of incommensurability
CAN YOU SOLVE THIS PARADOX
by Jonathan Tennenbaum
Moving from singly-extended, linear geometry, to
doubly-extended (plane) geometry, provides us with a relatively unique
experiment for the solution of the paradox presented above.
Synthetic plane geometry excels over singly-extended
linear geometry in virtue of the principle of angular extension
(rotation), as embodied by the generation of the circle and its lawful
divisions. Among the latter, the square (via the array of its four
vertices) is most simply constructed, after the straight line itself, by
twice folding or reflecting the circle onto itself.
Having constructed a square by these or related
means, designate its corners (running around counterclockwise) P, Q, R,
and S. {(Figure 1)} Our experiment consists in “unfolding” the
relationship between the two characteristic lengths associated with the
square: side PQ and diagonal PR. These two shall play the role of the
segments “A” and “B” in our previous discussion. (Note: the following
constructions are much easier to actually carry out, than to describe in
words. The reader should actually cut out a square and do the indicated
constructions.)
For our purposes it is convenient to focus, not on
the whole square, but on the right triangle PQR obtained by cutting the
square in half along the diagonal PR. {(Figure 2)} Note, that the sides
PQ and QR have equal length (PQR is a so-called isoceles right
triangle); furthermore, the angle at Q is a right angle and the angles
at P and R are each half a right angle.
To compare A (= PQ) with B (= PR), fold the triangle
in such a way, that PQ is folded exactly onto (part of) the line PR.
Since PQ is shorter than PR, the point Q will not fold to R, but will
fold to a point T, located between P and R. {(Figure 3)} By the
construction, PQ and PT are equal in length. Next, note that the axis of
folding, which divides the angle at P in half, intersects the side QR
at some point V, between Q and R. Observe, that the indicated operation
of folding brings the segment QV exactly onto the segment TV.
Observe also, that through the indicated folding of
the triangle, the triangular region PVT is exactly “covered” by the
region PVQ, while the smaller triangle portion VTR is left “uncovered,”
as a kind of higher-order “remainder.”
Focus on the significance of that smaller triangle.
Note, that in virtue of the construction itself, VTR has the same angles
and shape (i.e., is similar to) the original triangle PQR.
Euclid’s Algorithm Again
Comparing the original triangle to the smaller
“remainder” triangle VTR, we can easily see that the former’s sides are
derived from the latter’s by relationships very similar to, though
slightly different from, the steps of the so-called Euclid algorithm!
(See Part I, in our issue dated June 2, 1997.)
First, in fact, the side RT results from subtracting
the segment PT, equal in length to the original triangle’s side PQ, from
the original triangle’s hypotenuse PR. Second, the hypotenuse VR of the
small triangle derives from the side QR of the original triangle, by
subtracting the segment QV, while the latter (in virtue of the folding
operation and the similarity of triangles) is in turn equal to TV, which
again is equal to RT. In summary: if the side and hypotenuse of the
original triangle are A and B, respectively, then the corresponding
values for the smaller triangle will be A? = B – A and B? = A – A?.
{(Figure 4)}
Lurking Paradox
The reader might already notice an extraordinary
paradox lurking behind these relationships: Were A and B to have a
common divisor C, then that same C would–in virtue of the just-mentioned
relationships–also have to divide A? and B?. What is paradoxical about
that? Well, the smaller triangle is similar to the larger one, so we
could carry out the same construction upon it, as we did to derive it
from the original triangle. The result would be a third, much smaller
triangle of the same proportions, whose leg and hypotenuse, A? and B?,
would thereby also have to be divisible by the same unit C. And yet,
continuing the process, we would rapidly arrive at a triangle whose
dimensions would be smaller than C itself!
We are thus faced with the inescapable conclusion,
that A and B cannot have a common divisor in the sense of linear
Euclidean geometry. The relationship between A and B cannot be expressed
as a simple ratio of whole numbers. As Kepler puts it in his “World
Harmony,” the ratio of A to B is Unaussprechbar–it
cannot be “spoken”; by which Kepler means, it is not communicable in
the literal, linear domain. But Kepler emphasizes at the same time, that
it is {knowable} ( wissbar), and is precisely communicable {by other means.}
Evidently, the cognition of such linearly
incommensurable relationships, requires that we abandon the notion, that
simple linear magnitudes (so-called scalar magnitudes) are
ontologically primary. Our experiment demonstrates, that such magnitudes
as the ratio of the diagonal to the side of a square (commonly referred
to algebraically as the square root of two) are not really linear
magnitudes at all, but are “multiply extended,” geometrical magnitudes.
They call for a different kind of mathematics. What we lay out on the
textbook “number line” are only shadows of the real process, occuring in
a “curved” universe. This coheres, of course, with Johannes Kepler’s
reading of the significance of Golden Mean-centered spherical harmonics
in the ordering of the solar system, and in microphysics as well.
Analysis Situs Relationship
The relevant relationship for analysis situs,
in the preceeding discussion, is not between the diagonal and side of a
square; but rather that between the hypotheses underlying the linear
domain, sketched in Part I of our discussion, and the superior
standpoint implied in Part II.
A final note: Observe the rotation and change of
scale of the smaller triangle relative to the larger. Our experimental
{transformation} of the larger triangle into the smaller, similar
triangle, as an {inherent feature} of the relationship of A to B,
already points in the direction of Gauss’ complex domain, and the
preliminary conclusion, that the complex numbers are ontologically
primary–more real–than the so-called “real numbers.”
(Anticipating what might be developed in other
locations: The transformation constructed above, belongs to the
so-called “modular group” of complex transformations, which are key to
Gauss’ theory of elliptic functions, quadratic forms, and related
topics. Gauss, in effect, reworks the central motifs of Greek geometry,
from the higher standpoint of the complex domain.)
Hypergeometric Curvature
by Bruce Director
Let us turn our investigations to the domain of
manifolds of a Gauss-Riemann hypergeometrical form. There is no need, as
too often happens, for your mind to glaze over as you read the above
mentioned words. Lyn has given us ample guidance for this effort, most
recently in his memo on non-linear organizing methods.
Over the next few weeks, let us set a course, by way
of several preliminary exercises that will shift our investigations from
manifolds of constant curvature, that we’ve been looking at for the
last couple of months, to investigations of manifolds of non-constant
curvature.
A WARNING: these exercises should not be taken as
some type of definition of the concepts involved, any more than bel
canto vocalization should be taken as a substitute for singing classical
compositions. However, without the former, the latter is unattainable.
As a first start, conduct the following experiment,
that was alluded to in the previous pedagogical discussion on the
pentagramma mirificum:
Think of a surface of zero curvature, represented as a
flat piece of paper. This manifold is characterized by the assumption
of infinite extension in two directions. The intersection of these two
infinitely extended directions produces a singularity: a right angle, to
which all geodetic action is referred.
Now, draw a right triangle, labelling the vertices
BAC, with the right angle at A. Extend the hypothenuse BC to some
arbitrary point D. (BCD will all lie on the same line.) At D, draw a
line perpendicular to line BCD, and extend line AC until it intersects
the perpendicular from D. Label that point of intersection E. (You will
now have produced two right triangles, with a common vertex at C. The
extension of leg AC of the first triangle, will form the hypothenuse CE
of the second triangle CDE. Continue this action by extending line ACE
to some point F. At F, produce a perpendicular line, and extend leg DE
of triangle CDE until it meets the new perpendicular at some point G.
Now you will have three right triangles, BAC, CDE,
and EFG forming a kind of chain. Continue to produce this chain of right
triangles, by extending the hypothenuse EF of triangle EFG to some
arbitrary point H. Draw a perpendicular to H and extend leg FG until the
two meet at some point I. Now the chain has four triangles in it.
Keep adding to the chain of triangles in the same
manner. You will notice that after every three triangles, the chain
“turns” a corner. After the chain has eight triangles, if the
appropriate lengths were chosen, the triangle will close. The closed
chain of triangles, will resemble two intersecting rectangles. (We leave
it the reader to discover what the appropriate lengths are for the
chain to exactly close. As you will discover, the fundamental point is
not lost, even if arbitrary lengths are used. In that case, the
orientation of the 9th triagle will be identical to the 1st.)
Now produce the same action on a sphere, i.e. a
surface of constant positive curvature. Begin with a right spherical
triangle BAC. Extend its hypothenuse to some point D. At D, draw an
orthogonal great circle arc. Extend the side AC until it intersects the
orthogonal arc you just drew from D. Continue producing this chain of
spherical triangles. You will discover, that the chain of right
triangles on the sphere, closes after five “links” have been produced.
In other words, the pentagramma mirificum!
(If each hypothenuse is extended to an arc length of
90 degrees, the chain will perfectly close after 5 links. If an
arbitrary arc length is used, as in the plane, the chain will not
perfectly close, but the orientation of the 6th and 1st triangle will be
the same. On a sphere, the lengths need not be arbitrary, as a 90
degree arc length is determined by the characteristic curvature of the
sphere. On a plane, no such ability to determine length exists.
Now, think about the results of this experiment. The
same action was performed on a manifold of zero-constant curvature and a
manifold of constant positive curvature. The same action on, two
different manifolds, produces two distinctly different periodicities.
What in the naive imagination’s conception of the plane and sphere,
accounts for two completely different periodicities arising from exactly
the same process?
Now try a second experiment:
Stand in a room fairly close to two walls. Mark a dot
on the ceiling directly above your head. Point to that dot and rotate
your arm down 90 degrees so that you’re pointing to a place on the wall
directly in front of you. Mark a dot on that wall. Point to that dot,
and rotate your arm 90 degrees horizontally to a point on the wall
directly to your right (or left). Mark a dot on that wall at that point.
As presented in previous pedagogicals, the manifold
of action, that generated the positions of these three dots, is
characteristic of a surface of constant positive curvature, i.e. a
sphere. The three dots are vertices of a spherical equilateral triangle.
Now, take some string and masking tape and connect
the dots to one another with the string. Since the strings form the
shapes of catenaries, those same dots are now the vertices of a
negatively curved triangle.
Finally, in your mind, connect the dots with straight lines, and those same dots represent vertices of a Euclidean triangle.
From this construction, the same three positions lie on three different surfaces.
But, there is also another type of “surface”
represented in this experiment. A hypergeometric manifold characterized
by the change in curvature from negative, to zero, to positive
curvature.
This is not simply a trivial class room experiment.
In our previous discussions, we generated the concept of a sphere, as a
manifold of measurement of astronomical observations. Instead of being
in a room, the three dots can be thought of as stars, whose positions on
the celestial sphere are 90 degrees apart.
But, couldn’t the relationship of these three stars,
also be conceived to lie on a surface of constant negative curvature? In
1819, Gauss’ collaborator Gerling forwarded to Gauss the work of a
friend of his named Schweikart, a professor of law whose avocation was
mathematics and astronomy. Schweikart had developed a conception, that
he called, “Astralgeometrie”, that conceived of the spatial relationship
among astronomical phenomena as a negatively curved manifold. Gauss
replied, that Schweikart’s ideas gave him, “uncommonly great pleasure”
to read and agreed with almost all of it. In his reply, Gauss added a
few additional ideas to Schweikart’s hypothesis.
It should come as no surprise, that Gauss would
receive Shweikart’s work so warmly. Three years earlier, Gauss had
expressed an even more advanced notion, in his April 1816 letter
Gerling, that we have cited several times before, most recently two
weeks ago:
“It is easy to prove, that if Euclid’s geometry is
not true, there are no similar figures. The angles of an equal-sided
triangle, vary according to the magnitude of the sides, which I do not
at all find absurd. It is thus, that angles are a function of the sides
and the sides are functions of the angles, and at the same time, a
constant line occurs naturally in such a function. It appears something
of a paradox, that a constant line could possibly exist, so to speak, a
priori; but, I find in it nothing contradictory. It were even desirable,
that Euclid’s Geometry were not true, because then we would have, a
priori, a universal measurement, for example, one could use for a unit
of space (Raumeinheit), the side of an equilateral triangle, whose angle
is 59 degrees, 59 minutes, 59.99999… seconds.”
I’m sure you found Gauss’ choice of a triangle whose
angle is 59 degrees, 59 minutes, 59.99999… seconds curious. But, think
about it in the context of the above reference to a hypergeometric
manifold characterized by a change from negative to zero, to positive
curvature. The surface of zero curvature, is nothing more than a
singularity, in that hypergeometric manifold. The sum of the angles of a
triangle in a manifold of negative curvature will be less than 180
degrees. The 60 degree equilateral triangle is the maximum. On a surface
of positive curvature, the sum of the angles of a triangle is always
greater than 180 degrees. The 60 degree equilateral triangle in this
manifold, is the absolute minimum.
The triangle Gauss proposes for an absolute length,
does not exist in a manifold of negative curvature, nor in a manifold of
positive curvature. And, on a surface of zero curvature, it can no
longer define an absolute length. On the other hand, in a hypergeometric
manifold, that characterizes the change from negative, to zero, to
positive curvature, such a triangle represents, a unique singularity, a
maximum and a minimum, existing in the infinitessimally small interval,
in between two mutually distinct curvatures.
Enjoy the exercises. We’ll be back next week.
The Case For Knowing It All
by Bruce Director
A common mistake can occur, when replicating Gauss’
method for determining the Keplerian orbit of a heavenly body from a
small number of observations within a small interval of the orbit, that
has wider general implications. The error often takes the form, of
asking the rhetorical question, “What did Gauss do, exactly?” and,
answering that question, with a rhetorical step-by-step summary of a
procedure for calculating the desired orbit. In fact, Gauss himself
never published, or wrote down any such procedure. Gauss determined the
orbit of Ceres in the summer of 1801, and communicated only the result
of that determination, so that astronomers watching the sky could
re-discover the previously observed asteroid. It wasn’t until 8 years
later that Gauss, after repeated requests, published his “Summary
Overview,” and a year after that, his “Theory of the Motion of the
Heavenly Bodies Moving About the Sun In Conic Sections.”
Both these works, refrain completely from presenting
any step-by-step procedure — because no such procedure existed. Instead,
Gauss presented, first in summary form, than in a more expansive way,
the totality of interconnected principles that underlay the motion of
bodies in the solar system. These principles are not a collection of
independent functions that are mutually interdependent. Rather, that
mutual connectedness is itself a function, a representation of a higher
principle that governs planetary motion.
To illustrate this point, think of Kepler’s
principles of planetary motion, maliciously mis-characterized as
Kepler’s three laws. The elliptical nature of the orbit, the constant of
proportionality for each orbit (the “equal area” principle), and the
constant of proportionality between the periodic times and the
semi-major axis of the elliptical orbits, were each demonstrated by
Kepler as a valid principle governing planetary motion. But (as those
who’ve worked through the Fidelio article will recognize), all three
principles are inseparably linked in each small interval of every
planetary orbit. It is the functional relationship among these
principles, the “hypergeomtric” relationship, that is the essence of
Kepler’s discovery.
It is the “disassembly” of this hypergeometric
relationship, into separate independent functions, that has been the
hysterical obsession of the oligarchy and its lackeys, from Newton, to
Euler, to today’s academics.
Leibniz, in a letter to Huygens exposed this hoax from the get go:
“For although Newton is satisfactory when one
considers only a single planet or satellite, nevertheless, he cannot
account for why all the planets of the same system move over
approximately the same path, and why they move in the same direction….”
Or, from another angle: Nearly 20 years after his
discovery of the orbit of Ceres, Gauss took on the task of measuring the
Kingdom of Hannover, by means of a geodetic triangulation. In the
course of this investigation, which had many practical implications,
Gauss demonstrated a similar “hypergeometric” relationship. Each
triangle he measured was “infinitesimally” small with respect to the
entire Earth’s surface, and the deviation of those triangles from flat
ones was also small. As the network of triangles was extended, however,
the small deviation in each individual triangle, became an increasingly
significant factor in the measurement of the larger area covered by the
connected network of these triangles. Not only did the area measured
deviate from flat, but it also deviated from a spherical surface, and
more closely resembled an ellipsoidal surface. Furthermore, Gauss
discovered an “infinitesimally” small deviation from the astronomical
observation of his position on the Earth’s surface, and the position
determined by his triangulation. This led Gauss to the discovery of the
deviation of the Earth’s surface, from one of regular non-constant
curvature, such as an ellipsoid, to a surface of irregular, non-
constant curvature, that today is called the Geoid.
This defines a functional relationship of the
measurement of the relatively “infinitesimally” small triangles, and the
multiple surfaces on which these measurements were performed. That is,
each triangle measured, had to be thought of simultaneously as being on a
surface of zero-curvature (flat), constant curvature (spherical),
regular non-constant curvature (ellipsoidal), and irregular non-constant
curvature (the Geoid). The characteristics of each triangle changes
from surface to surface. But, in the real world, these surfaces are not
independent surfaces, simply overlaid on top of each other. There is a
functional relationship among them. Gauss’ genius was to recognize, not
only the interaction between the characteristic of curvature of the
surface, and the characteristic of the triangles measured, but also the
functional relationship that transformed one surface into another.
Or, from an even different angle: In 1832, after
nearing the completion of his geodetic survey, Gauss published the
results of the work he had been doing along the way. In his second
treatise on bi-quadratic residues, Gauss extended the concept of prime
numbers into the complex domain, transforming Eratosthenes’ Sieve. Gauss
showed that the characteristics of prime numbers, were also a function
of the nature of the surface, such that, for example, 5 is transformed
from a prime to a composite number. The number 5 exists in both domains,
but it’s nature changes, as the domain changes. The number 5 is not two
separate independent numbers. Again there is a functional relationship
between these two domains, the transformation, that provokes our minds
to a higher mode of cognition.
The above three examples, presented in summary form,
have been elaborated in previous pedagogical discussions, and will be
further elaborated in future ones. The intent in presenting this summary
juxtaposition, is to provoke some thought on the functional
relationship among these three. They are not three independent concepts.
There is a connection, whose active contemplation, gives rise to a
conception of functional relationship, that governs the generation of
each concept.
As Lyndon LaRouche has wisely advised us, “If you want to know anything, you have to know everything.”
Higher Arithmetic as a Machine Tool
by Bruce Director
Last week’s pedagogical discussion ended with the
provocative question: “If there exists no grand mathematical system
which can combine and account for the various cycles, then how can we
conceptualize the `One’ which subsumes the successive emergence of new
astronomical cycles as apparent new degrees of freedom of action in our
Universe? How do we master the paradoxical principle of Heraclitus, that
`nothing is constant except change?'”
This problem was attacked in a very simple and
beautiful way by C.F. Gauss, using purely the principles of higher
arithmetic, in his determination of the Easter date. Since the last
conference presentation, I have received several requests, to elaborate
more completely the derivation of Gauss’ algorithm. While the
development of Gauss’ program requires no special mathematical skills
other than simple arithmetic, it does require the conceptual skills of
higher arithmetic, i.e., the ability for the mind to unify an
increasingly complex Many into a One. This is a subjective question. We
are not looking for one mathematical formula, but a series of actions,
which, when undertaken, enable our minds to wrestle a seemingly unwieldy
collection of incommensurable cycles into our conceptual grasp. In a
certain sense, we are designing and building a machine tool to do the
job, but only the entire machine can accomplish the task. No single
part, or collection of parts, will be sufficient. The whole machine
includes not only the “moving parts,” but the concepts behind those
moving parts. All this, the parts and the concepts, must be thought of
as a “One,” or else, the machine, i.e., your own mind, comes to
screeching halt, while the earth, the moon, the sun, and the stars,
continue their motion, in complete defiance of your blocking.
Over the next few weeks, we will re-discover Gauss’
construction. But, in order to build this machine, you must be willing
to get your hands dirty and break a sweat, make careful designs, cut the
parts to precision, lift heavy components into place, and finally apply
the energy (agape) necessary to get the machine moving and keep it
moving.
In the beginning of his essay, “Calculation of
Easter,” published in the August 1800 edition of Freiherrn v. Zach’s
“Monthly Correspondence for the Promotion of News of the Earth and
Heavens,” Gauss states:
“The purpose of this essay, is not to discuss the
usual procedure to determine the Easter date, that one finds in every
course on mathematical chronology, and as such, is easy enough to
satisfy, if one knows the meaning and use of the customary terms of art,
such as Golden Number, Epact, Easter Moon, Solar Cycle, and Sunday
Letter, and has the necessary helping tables; but this task is to give,
independently from those helping conceptions, a purely analytical
solution based on merely the simplest calculation-operations. I hope,
this will not be disagreeable, not only to the mere enthusiast who is
not familiar with those methods, or for the case where one wishes to
determine the Easter date, under conditions in which the necessary
helping devices are not at hand, or for a year which cannot be looked up
in a calendar; but it also recommends itself to the expert by its
simplicity and flexibility.”
This article was published after Gauss had completed,
and was awaiting publication of the “Disquistiones Arithmeticae.” Of
the principles we will develop here, Gauss says:
“The analysis, by means of which the above formulas
are founded, is based properly on the foundations of {Higher
Arithmetic}, in consideration of which I can refer presently to nothing
written, and for that reason it cannot be freely presented here in its
complete simplicity: in the mean time, the following will be sufficient,
in order to lay the foundation of the direction of the concept and to
convince you of its correctness.”
Gauss’ choice of the problem of determining the
Easter date, to demonstrate the validity of the principles of his Higher
Arithmetic, is not without a healthy amount of irony, but the resulting
calculation was by no means Gauss’ only goal. As with LaRouche’s
current program of pedagogical exercises, Gauss recognized the
effectiveness for increasing the conceptual powers of the human mind, of
working through specific examples, which demonstrate matters of
principle. Gauss continued this approach in all his work, demonstrating
new principles as he conquered one problem after another. Gauss
repeatedly found that in these matters of principle, connections were
discovered between areas of knowledge which were previously thought to
be unrelated.
From the earliest cultures, the various cycles
described last week were accounted for separately, and their
juxtaposition was studied with aid of the different tables and
calculations Gauss mentioned above. These methods were adequate for
determining the date of Easter from year to year. Gauss’ calculation is
purely a demonstration of the power of the human mind, to create a new
mathematics, capable of bringing into a “One” that which the previous
state of knowledge considered unintelligible. For that reason, it suits
our present purpose.
To begin, we should think about the problem we intend
to work through: To determine the date of Easter for any year. Easter
occurs on the first Sunday, after the first full Moon (called the
Paschal Moon) after the Vernal Equinox. This entails three
incommensurable astronomical cycles: the day, the solar year, and the
lunar month; and one socially-determined cycle, the seven-day week.
Now look more closely at what this “machine-tool” must do:
1. It must determine the number of days after the
vernal equinox, on which the Paschal Moon occurs. This changes from year
to year. So the machine must have a function, which modulates the solar
year (365.24 days) with the lunar month (29.53 days).
2. Once this is determined the machine must also determine the number of days, remaining until the next Sunday.
The incommensurability of the solar year and the
lunar month is an ancient conceptual problem, upon whose resolution
man’s potential for economic progress rested. If one relied solely on
the easier-to-see lunar month, the seasons (which result from changes of
the position of the earth with respect to the sun) will occur at
different times of the year, from one year to the next. On the other
hand, if one relies on the solar year, some intermediate division
between the day and year is necessary, to measure smaller intervals of
time. Efforts to combine both the lunar cycle, and the solar cycle,
linearly into one calendar, creates a complicated mess. The
Babylonian-influenced Hebrew calendar is an example, requiring a special
priestly knowledge just to read the calendar. Shortly after the
publication of the Easter formula, Gauss applied the same method to a
much more complex chronological problem, the determination of the first
day of Passover, and in so doing, subjugating the Babylonian lunisolar
calendar to the powers of Higher Arithmetic.
In 423 B.C., the Greek astronomer Meton reportedly
discovered that 19 solar years contained 235 lunar months. This is the
smallest number of solar years, that contain an integral number of lunar
months. There is evidence that other cultures, including the Chinese,
discovered this same congruence earlier. By the following simple
calculation, we can re-discover Meton’s discovery. One solar year is
365.2425 days. 12 lunar months is 354.36 days, (12 x 29.53) or 11 days
less than the solar year. This means that each phase of the moon will
occur 11 days earlier than the year before, when compared to the solar
calendar.
(For example, if the new moon falls on January 1,
then after 12 lunar months, a new moon will fall on December 20 — 11
days before the next January 1. The next new moon will occur on January
19, 19 days after the next January 1.)
One solar year contains 12.368 lunar months (365.2425
/ 29.530). In 19 years, there are 6939.6075 days (365.2425 x 19). In 19
years of 12.368 lunar months, there are 6939.3137 days (19 x 12.368 x
29.530). That is, if you take a cycle of 6939 days, or 19 solar years,
the phases of the moon and the days of the solar year become congruent.
Despite Meton’s discovery, the Greek calendar was
still encumbered by a failed effort to combine the lunar months and
solar year into a single linear calendar cycle. Since 12 lunar months,
are 11 days short of the solar year, the Metonic calendar, like the
Babylonian influenced Hebrew calendar, required the intercalation
(insertion) of leap months in years 3, 5, 8, 11, 13, and 16 of the
19-year cycle.
In his “History,” Herodotus remarks on the
inferiority of the Greek method over the Egyptians, whose calendar was
based only on the harder-to-measure solar year. “But as to human
affairs, this was the account in which they all agreed: the Egyptians,
they said, were the first men who reckoned by years and made the year
consist of twelve divisions of the seasons. They discovered this from
the stars (so they said). And their reckoning is, to my mind, a juster
one than that of the Greeks; for the Greeks add an intercalary month
every other year, so that the seasons agree; but the Egyptians,
reckoning thirty days to each of the twelve months, add five days in
every year over and above the total, and thus the completed circle of
seasons is made to agree with the calendar.”
The oligarchical view of this matter is expressed by the Chorus-Leader in Aristophanes, “The Clouds”:
“As we prepared to set off on our journey here,
The Moon by chance ran into us and said she wanted
To say hello to all the Athenians and their allies,
but she’s most annoyed at your treating her so shamefully
despite her many evident and actual benefactions.
First off, she saves you at least ten drachmas a month in torches:
that’s why you all can say, when you go out in the evening,
No need to buy a torch, my boy, the moonlight’s fine!
She says she helps in other ways too. But you don’t keep
your calendar correct; it’s totally out of sync.
As a result, the gods are always getting mad at her,
whenever they miss a dinner and hungrily go home
because you’re celebrating their festival on the wrong day,
or hearing legal cases or torturing slaves instead of sacrificing.
And often, when we gods are mounring Memnon or Sarpedon,
you’re pouring wine and laughing. That’s why Hyperbolus,
this year’s sacred ambassador, had his wreath of office
blown off his head by us gods, so that he’ll remember well
that the days of your lives should be reckoned by the Moon.”

In 46 B.C., with the adoption of the Julian calendar,
all attempts to incorporate the lunar cycle into the calendar were
abandoned. But, it wasn’t until Gauss’ development of higher arithmetic,
ironically based on a re-working and non-linear extension of classical
Greek astronomy and geometry, that man had the ability to encompass the
seemingly incommensurable lunar month and solar year into a One.
With these discoveries in mind, we can begin to
construct the first components of the machine, which will determine the
number of days from the vernal equinox, to the Paschal Moon. If we fix
the vernal equinox at March 21, our first component must determine some
number D, which, when added to March 21, will be the date of the Paschal
Moon. (March 21 was the date set at the Council of Nicea. The actual
Vernal Equinox, can sometimes occur in the late hours of March 20, or
the early hours of March 22.) The Paschal Moon will occur on one of 30
days, the earliest being March 21, the latest being April 19. The
variation from year to year, among these 30 possible days, is a
reflection of the 19- year Metonic cycle. So, our machine, must make two
cycles, the 19-year Metonic cycle, and this 30-day cycle into a One.
This requires some thinking. Since 12 lunar months
are 11 days less than the solar year, any particular full moon will
occur 11 days earlier than the year before. Naive imagination tells us
that if we set our machine on any given year, all it need do is subtract
11 days to find the Paschal Moon on the next year. But we have a
boundary condition to contend with. The Paschal Moon can never occur
before March 21. So, when the Paschal Moon occurs in March, and our
machine subtracts 11 days, to get the date of the Paschal Moon the
following year, the new date will be before March 21. That will do us no
good at all.
To determine the date of the Paschal Moon from one
year to the next, our machine must do something different when the
Paschal Moon occurs in March, than when it occurs in April. When the
Paschal Moon occurs in April, the machine must subtract 11 days, to
determine the date for the following year. But when it occurs in March,
the machine must add 19 days to determine the date for the following
year.
To construct this component of the algorithm, Gauss
began with a known date, and abstracted the year-to-year changes, with
respect to that date. In reference to the 19-year Metonic cycle, he
chose to begin the calculation with the date of the Paschal Moon in the
first year of that cycle (i.e., those years which, when divided by 19,
leave 0 as a remainder, or are congruent to 0 relative to modulus 19).
In the 18th and 19th centuries, that date was April 13, or March 21 + 23
days.
For clarity, we can make the following chart:
Year Residue Paschal Moon # Days Aft. Equinox (D)
(Mod 19)
1710 0 April 13 23 days 1711 1 April 2 23 – 11 days
1712 2 March 22 23 – (2 x 11) 1713 3 April 10 23 – (2 x 11) + 19 1714 4
March 30 23 – (3 x 11) + 19
(The reader is encouraged to complete this entire
chart. When you do this notice the interplay between the 19 year, and 30
day cycles.)
From the chart, you should be able to see the
relevant oscillation. For example, for year 1713, were we to have
subtracted another 11 days from the year before, we’d arrive at the date
of March 11. A full moon certainly occurred on that day, but it wasn’t
the Paschal Moon, because March 11 is before the Vernal Equinox. The
Paschal Moon, in the year 1713, occurred 30 days later than March 11, on
April 10. (March 22 – 11 + 30; or March 22 + 19)
The number of days added or subtracted changes from
year to year, in a seemingly non-regular way. What is constant is
change. But this step-by-step process, is really no different than if we
had a series of tables.
Gauss’ next step, is to transform the two actions,
subtracting 11 days or adding 19 days, into one action. There are many
ways this can be done. The determination of the appropriate one, is a
matter of analysis situs, and involves one of the most important methods
of scientific inquiry: {inversion}. The principle of inversion is
characteristic of all Gauss’ work. It is one thing to be given a
function, and then calculate the result. The inverse question is much
more difficult. Given a result, what are the conditions which brought
about that result? In the latter case, there are many possible such
conditions, which cannot be ordered without consideration of higher
dimensionalities. (This subject will be treated more in future
pedagogical discussions.)
Our immediate problem can be solved, if we think
about it from the standpoint of inversion. All the year-to-year
differences between the dates of the Paschal Moon, are either congruent
relative to modulus 11 or modulus 19. But neither of these moduli are
relevant for the task at hand. A different modulus must be discovered,
which is not self-evident from the chart, but is evident from the higher
dimensionality of the complete process. As discovered earlier, the
Paschal Moon occurs on one of 30 days between March 21, and April 19. We
need to discover a means, under which the oscillation of the dates of
the Paschal Moon, can be ordered with respect to modulus 30. If we
number these days 0-29, the numbers 0 to 29 each represent different
days, and are all non-congruent relative to modulus 30.
Gauss chose to combine the two actions into one, by
adding 19 days to {every} year, and subtracting 30 days from those years
in which the Paschal Moon occurs in April. (For example, in our chart
above, the year 1711 would be calculated: 23 + 19 – 30; the year 1712
would be calculated, 23 + (2 x 19) – (2 x 30).
Since all numbers whose differences are divisible by
30, are all congruent relative to modulus 30, adding or subtracting 30
days from any interval, will not change the result. Gauss has
transformed this problem into a congruence relative to a single modulus:
30. So the first component of our machine takes the year, finds the
residue, multiplies that by 19, adds 23, divides by 30 and the remainder
is the number of days from the Vernal Equinox to the Paschal Moon.
Or in Gauss’ more condensed language: Divide the year
by 19 and call the remainder a. Then divide (23 + 19a) by 30 and call
the remainder D. Add D to March 21 to get the date of the Paschal Moon.
No mountain was ever climbed that didn’t require some
sweat. Or, put another way, in order to build the Landbridge, you have
to move some dirt.
Next week: From the Paschal Moon to Easter.
Higher Arithmetic as a Machine Tool–Part II
by Bruce Director
Last week we completed the first step of the
development of Gauss’ algorithm for calculating the Easter date, using
the principles of Higher Arithmetic. This week we continue the climb.
Those experienced in climbing mountains are aware, that as one
approaches the peak, the climb often steepens, requiring the climber to
find a second burst of energy. Even though last week’s climb might have
required some exertion, you’ve had a week’s rest, and a national
conference in the intervening period. Armed with the higher conceptions
of man expressed by Lyn and Helga at the conference, everyone is
well-equipped to complete this climb.
Again it is important to keep in mind, that the
determination of the date of Easter was not a goal in itself for Gauss.
Rather, Gauss understood that working through problems, which required
the discovery of new principles, was the only way to advance human
knowledge.
Last week, we worked through the first part of the
task of determining the date of Easter. Since Easter is the first Sunday
after the first full moon, after the vernal equinox, the first job of
our machine tool, is to determine the date of the first full moon. This
requires bringing into a One, three astronomical cycles: the day, the
lunar month, and the solar year. The second part of the job, to
determine the number of days from the Paschal Moon until the next
Sunday, requires bringing into a One, various imperfect states of human
knowledge.
It was a major step forward, for society to abandon
all attempts to reconcile the lunar and solar years into one linear
calendar, and adopt the solar year, as the primary cycle on which the
calendar was based. The conceptual leap involved was to base the
calendar on the more difficult to determine solar year, instead of the
easier to see lunar months. The implications of this conceptual leap for
physical economy are obvious. What is worth emphasizing here, is, that
this is a purely subjective matter, whose resolution determines physical
processes. This development, however, was not without its own problems.
While the disaster of trying to reconcile the lunar
and solar cycles, becomes evident within the span of several years, the
problems of the solar calendar, don’t become significant within in the
span of a single human life.
As discussed last week, the solar year is
approximately 365.24 days. In 46 B.C., the calendar reform under Roman
Emperor Julius Caesar, set the solar year at 365.25 days, which was
reflected in the calendar, by three years of 365 days, followed by a
leap year of 366 days. The number of days in this arrangement, would
coincide every four years. Under this arrangement, man has imposed on
the astronomical cycles, a new four-year cycle. From the standpoint of
Gauss’ Higher Arithmetic, leap years are congruent, in succession to 0
relative to modulus 4, followed by non-leap years congruent to 1, 2, or 3
relative to modulus 4.
Like all oligarchs who delude themselves that their
rule will last forever, Julius Caesar’s arrogance of ignoring the
approximately .01 discrepancy between his year, and the actual
astronomical cycle, became evident long after his Empire had been
destroyed. This .01 discrepancy, while infinitesimal with respect to a
single human life, becomes significant with respect to generations,
causing the year to fall one day behind every 187 Julian years. By the
mid-16th century, this discrepancy had grown to 11 days, so the
astronomical event known as the vernal equinox was occurring on March
10th instead of March 21st. The economic implications of such a
discrepancy is obvious.
This lead to the calendar reforms of Pope Gregory
XIII in 1587. In the Gregorian calendar, the leap year is dropped every
century year, except those century years divisible by 400. This
decreases the discrepancy of the .01 day, but doesn’t eliminate it
altogether. In order to get the years back into synch with the seasons,
Pope Gregory dropped 11 days from the year 1587. Other countries
reformed their calendar much later, having to drop more days, the longer
they waited. The Protestant states of Germany, where Gauss lived,
didn’t adopt the calendar reform until the early 1700s. The English
didn’t change their calendar until 1752. The Russians waited until the
Bolshevik revolution.
The other human cycle involved in this next step of
the problem is the seven-day week. There is no astronomical cycle which
corresponds to the seven-day week. While the Old Testament’s Exodus,
attributes the seven-day week to God’s creation of the universe, Philo
of Alexandria, in his commentaries on the Creation, cautions that this
cannot be taken literally. Philo says the Creation story in Genesis 1,
must be thought of as an ordering principle, not a literal time-table.
Here is another example of what Lyn has discussed about the
unreliability of a literal reading of the Old Testament. The idea that
creation took seven days, shows up in Exodus, contradicting the
conception of an ordering principle of Creation in Genesis 1.
Of importance for our present problem, is that, the
seven-day weekly cycle runs continuously, and independently, from the
cycles of the months, (either calendar or lunar) and the years. What
emerges is a new cycle which has to be accounted for. Each year, the
days of the week occur on different dates. For example, if today is
Saturday, September 6, next year, September 6 will be on a Sunday.
However, when a leap year intervenes, the calendar dates move up two
days. This interplay between the seven-day week and the leap year,
creates a 28-year cycle, before the days of the week and the calendar
dates coincide again. This cycle also has to be accounted for in Gauss’
algorithm.
So, to climb that last step, from the Paschal Moon to
Easter, we have to bring into a One, these two human cycles, the leap
year, and the seven-day week.
Before going any further, one must first remember a
principle of Higher Arithmetic. Under Gauss’ conception of congruence,
it is the {interval} between the numbers, on which the congruence is
based, not the numbers themselves. We are relating numbers by their
intervals. Consequently, when we add or subtract multiples of the
modulus to any given number, the congruence relative to that modulus
doesn’t change. For example, 15 is congruent to 1,926 relative to
modulus 7. The interval between 15 and 1,926 (1,911) is divisible by 7.
If, for example, we subtract 371 (7×53) from 1,926, the result will
still be congruent to 15. The reader should do several experiments with
this concept, in preparation for what follows.
It were useful to restate here Gauss’ entire algorithm:
Divide the year by 19 and call the remainder a
Divide the year by 4 and call the remainder b
Divide the year by 7 and call the remainder c
Divide 19a+23 by 30 and call the remainder d
(This was discovered last week)
Divide 2b+4c+6d+3 by 7 and call the remainder e
(This is today’s task.)
The number of days from the Paschal Moon until Easter
Sunday can be at least 1 and at most 7 days. Because Easter is the
first Sunday {after} the first full moon, which follows the Vernal
Equinox, the earliest possible date for Easter is March 22. Therefore,
Easter will fall on March 22 + d (the number of days to the Paschal
Moon) + E (the number of days until Sunday.) E, therefore, will be one
of the numbers 0-6, or the least positive residues of modulus 7.
Keeping in mind the exercise we discussed above, the
number of days between any two Sundays is always divisible by 7, no
matter how many weeks intervene. Consequently, the interval of time
between March 22 + d + E (Easter Sunday of the year we’re trying to
determine) and any given Sunday in any previous year, will be divisible
by 7. So if we begin with a definite Sunday, we can discover a general
relationship for determining the date of Easter.
Gauss chose Sunday, March 21, 1700 as his Sunday
reference date. Next, he determined a relationship for how many total
days elapsed between March 21, 1700 and any subsequent Easter Sunday.
That total would be 365 days times the number of elapsed years, plus the
number of leap days in those elapsed years. (Remember every four years,
has one leap day in it.) Again, this number will be divisible by 7, no
matter how many years intervene.
If A is the year for which we want to determine the
date of Easter, A-1700 will be the number of elapsed years. (For
example, if we want to find Easter in the year 1787, then there were 87
elapsed years (1787-1700).
If we call i the total number of leap days, then the
total number of days between Sunday March 21, 1700 and March 22 + d + E,
for the year we’re investigating will be:
1 + d + E + i + 365(A-1700)
This number is divisible by 7, (because it is the number of intervening days from one Sunday to another).
At this point, the main conceptual problem has been
solved. The date of Easter can be determined as March 22 + d + E, with d
being determined by the calculation discussed last week, and E
determined by the calculation which will be developed below.
Gauss was never content, unless he found the absolute
simplest way to accomplish his task. All that remains is to simplify
the above calculation so that E will be the residue which arises when
the above number is divided by 7. Gauss accomplished this by repeatedly
employing the principle, cited above, that adding or subtracting
multiples of the modulus, doesn’t change the congruence. I include the
following applications of this principle, even though it is expressed by
some algebraic manipulations. The reader should focus on the addition
and subtraction of multiples of the modulus 7.
To determine the number of leap days, i. we must
first determine what relationship the year in question is to the leap
year. Or, in the language of Gauss’ Higher Arithmetic, what is the least
positive residue relative to modulus 4 of the year in question? This is
the remainder b in Gauss’ algorithm. (For example, if the year is 1787,
the least positive residue relative to modulus 4 is 3. That is, 1787 is
three years after a leap year. So the total number of leap years
between 1787 and 1700 is 87-3/4=21, or 1787-1700-3/4.)
In Gauss’ formula, the total number of leap days i will be:
1/4(A-b-1700)
If A is between 1700 or 1799. If A is between 1800
and 1899, then we have to subtract 1 because 1800 is not a leap year.
For now, we will stick to the 18th century.
So the total number of days between March 21, 1700 and Easter Sunday in year A, will be:
1 + d + E + 365(A-1700) + 1/4(A-b-1700).
And this number must be divisible by 7.
This is pretty complicated and cumbersome. But as we
know from Gauss’ Higher Arithmetic, if we add or subtract multiples of
7, the result will also be divisible by 7. So Gauss, through the
following steps, adds or subtracts multiples of 7, in order to bring
this unwieldy formula into a simple calculation.
First he adds the fraction 7/4(A-b-1700) to the above making: 1 + d + E + 365(A-1700) + 8/4(A-b-1700)
Multiplying all this out gives us: 1 + d + E + 367(A-1700)-2b which equals: 1 + d + E + 367A – 623,900 – 2b
Then Gauss subtracts 364(A-1700) (which is divisible by 7) which gives: d + E + 3A – 5099 – 2b
Then Gauss adds 5096 (which is divisible by 7) to get: d + E + 3A – 3 – 2b
Now Gauss eliminates any need for the reference date
by replacing A in the following way. First, we divide the year by 7 and
call the remainder c. That means, if we subtract c from the year, the
result will be divisible by 7. Or, A-c will also be divisible by 7. In
the next step, Gauss subtracts 3 times A-c or 3A-3c which gives: d + E +
3c – 3 – 2b
Finally Gauss subtracts this from 7c – 7d which gives: 3 + 2b + 4c + 6d – E.
Which means E is the remainder if we divide 3 + 2b + 4c + 6d by 7. So the determination of the Easter date is March 22 + d + E.
Unfortunately our work is not completely done.
Because in the Gregorian calendar, not every century year is a leap
year, the algorithm must change from century to century. Gauss also
solved this problem using principles of Higher Arithmetic. We will take
this up in future pedagogical discussions.
Heraclides of Pontus Was No Baby Boomer
By Robert Trout
It is, today, a commonly believed myth that before
the time of Columbus, everyone thought that the earth was flat, and
located in the center of the universe, with the rest of the universe
orbiting around it. In fact, over 2000 years ago, Greek scientists,
using only the most simple instruments, developed an advanced conception
of the universe that could have explained the ordering of the solar
system, and how this ordering determined the seasonal cycles on the
earth. They had even discovered the precession of the equinoxes to begin
comprehending the longer astronomical cycles. Today, we will examine
Greek discoveries in astronomy through Heraclides of Pontus, who refuted
the world view of the baby boomer generation, more than 2000 years
before the first boomer was born.
Greek astronomy was based on a scientific method
which was in opposition to the methods used in ancient Babylon. The
astronomy of the ancient Babylonians is an excellent example of how an
oligarchical society does not develop science. The Babylonian oligarchy
used a pantheon of cults to control the population. The priest caste
studied the heavens for the purposes of omen astrology and for the
improvement of their calendar, which was a lunar one unlike the superior
Egyptian solar calendar.
The Babylonians left behind thousands of cuneiform
tablets pertaining to astronomy. However, in the Babylonian approach to
astronomy, not even a trace of a geometrical model is visible. Instead,
they developed numerical methods using arithmetic progressions, in a
fashion that would remind one of Euler. Using these methods, they were
able to predict certain phenomena with the moon, within an accuracy of a
few minutes. Although they compiled almost complete lists of eclipses
going all the way back to 747 B.C., the Babylonians collected almost no
reliable data on the motion of the planets. They never developed
accurate methods for measuring the location of celestial objects, and
never showed any interest in developing a unified conception of the
cosmos.
Greek science developed as part of a cultural current
which rejected the domination of an oligarchy. In the Homeric epics,
man was presented matching his wits against the oligarchical Greek
goods. In Aeschylus’s play, “Prometheus Bound,” the character,
Prometheus, the Greek word for forethought, gives science to mankind, to
free them from the pagan gods.
Greek culture, was, itself, split between a
pro-republican and an oligarchical view, which is brought into sharpest
relief by the opposing outlooks of Plato and Aristotle. Plato supplied
the scientific method which has guided science ever since. He launched a
research project to find “what are the uniform and ordered movements by
the assumption of which the apparent movements of the planets can be
accounted for.”
Around 150 A.D., under the Roman Empire, the
fraudulent astronomy of Ptolemy was imposed, which was based on the
ideology of Aristotle. The writings of the Greeks, with few exceptions,
were not preserved, so the only records that exist are usually
descriptions by later commentators. Therefore, we must reconstruct these
discoveries, based on knowing how the mind functions.
Unlike the Babylonians, the ancient Greek astronomers
sought a geometrical ordering principle behind the phenomena which are
visible in the heavens. An early Greek astronomer would have seen that
the motion of the objects in the sky appeared to follow regular cycles.
As well, the cycles of the sun, moon, stars, and planets did not exactly
correspond, giving rise to longer subsuming cycles.
Each day he would see the sun appear to rise in the
east, cross the sky, and set in the west. The moon also rose in the
east, crossed the sky and set. However, the moon seemed to travel slower
than the sun, with the sun going through a complete extra rotation in
approximately 29 1/2 days. The appearance of the moon also changed,
going through a complete cycle of phases approximately every 29 1/2
days.
At night, he would see stars, most of which appeared
to maintain a fixed relationship to each other. The Greeks developed a
conception of a celestial sphere to explain the fixed relationships of
these stars. The “fixed stars” rotated as a group throughout the night,
around a point in the northern sky which appeared to not move. Also, the
position of the “fixed stars” appeared to shift slightly, from day to
day, with the same east to west rotation. This slight shift, from day to
day, in the fixed stars appeared to go through a complete cycle each
year, corresponding to the cycle of the seasons. A number of other
cycles corresponded to the year. The sun’s path across the sky changed
each day following a yearly cycle.
In addition to the “fixed stars” of the celestial
sphere there were a few objects, which they named planets or wanderers,
because, although they appeared very similar to stars, they did not
remain in the same position in relation to the celestial sphere, but
were constantly moving with respect to the rest of the stars.
One of the first known Greek astronomers, Thales, (ca
624 to 547 B.C.) is reported to have measured the angular size of sun
and moon at approximately 1/2 degree. Thales, developed basic relations
of similar triangles, such as demonstrating that the ratio of 2 sides is
the same for similar triangles, and used this principle to measure
relations in the cosmos.
Pythagoras (ca 572-? B.C.) is credited with
discovering that the earth is approximately a sphere, and that the
“morning star” and the “evening star” were the same, what we, today,
call the planet Venus. He is also credited with discovering that the
musical intervals are determined by number, and recognizing that the
universe was governed by the same laws of harmony as those which govern
music.
Since no writings from Pythagoras or his followers
have survived, we can only speculate how he discovered that the earth is
spherical. He might have concluded this based on conceptualizing the
cause of eclipses. The discovery of the cause of eclipses is attributed
to Anaxagoras (500-428 B.C.), who hypothesized that the sun was a red
hot stone and the moon made of earth, for which he was accused of
impiety. He recognized that the source of the moon’s light is the
reflection of sunlight. He is credited with discovering that an eclipse
of the moon is caused by the earth blocking the sun’s light from shining
on the moon, and that an eclipse of the sun is caused by the moon
blocking the sun’s light from reaching the earth.
Eclipses of the moon give evidence that the earth is
spherical. The shadow that the earth makes on the moon during an eclipse
is always circular, regardless of the direction from which the sun is
shining. This is only true of a sphere, in the geometry that the Greeks
were then developing.
Pythagoras could have discovered that the earth is
spherical, because he conceptualized the idea of curvature that
Erathosthenes understood, which enabled him to design his famous
experiment to measure the circumference of the earth. Finally,
Pythagoras could have concluded that this must be true, because he
recognized that the universe is ordered by geometry and he thought that
“the sphere is the most beautiful of solid figures.”
The “morning star” and the “evening star” are the two
brightest objects in the night sky after the moon. The two phenomena
each go through visible regular cycles, which Pythagoras was able to see
were reflections of a subsuming cycle which ordered the two visible
cycles.
The “evening star” first appears slightly above the
western horizon shortly, after the sun sets. Over a period of months, it
will appear each evening, when the sun sets, in a slightly higher
position above the western horizon, travelling westward each night
apparently in tandem with the rotation of the celestial sphere.
Eventually it will appear, when the sun sets, at a position
approximately 1/2 of a right angle above the western horizon. It will
then start to appear, each night, at a slightly lower position above the
western horizon, until it does not appear at all in the evening sky.
However, shortly thereafter, the morning star becomes visible.
The “morning star” will first appear, on the eastern
horizon immediately before the sun rises. Each night, it will rise
slightly earlier, and travel westward apparently in tandem with the
rotation of the celestial sphere. Its height above the eastern horizon,
when the sun rises, will increase each night, reaching a maximum of
slightly more than 1/2 of a right angle. It will then begin rising,
later each night until, it rises so late that its appearance is hidden
by the daylight. However, shortly after the morning star disappears, the
“evening star” will then reappear on the western horizon.
Conceptualize how Pythagoras could have approached
this problem, without all the knowledge of the solar system that you
think that you know. For Pythagoras to have hypothesized that these two
stars were the same, required that he approach the universe with the
understanding that it was ordered, lawfully, and its lawfulness was
comprehensible by human reason. Only then could he discover that the
appearances of the two visible phenomena could be lawfully explained as
the result of a process which could be comprehended by the mind but not
seen by the senses. His hypothesis could have been that the morning and
evening stars were the visible evidence of an object, which accompanied
the sun in the sun’s apparent daily rotation around the earth, while
oscillating back and forth over a period of approximately 20 months,
half the time preceding the sun and half the time following it.
Pythagoras’s discovery, that these two visible
phenomena in the night sky were the same, may seem trivial. However, his
discovery set the stage for Heraclides of Pontus, approximately 200
years later, to overthrow the baby boomer conception of the universe, as
we shall see below.
Philolaus, (second half of 5th century B.C.), a
member of the Pythagorean school, introduced conceptions of motion to an
earth, which had previously been thought of as largely static.
Philolaus is credited with removing the earth from the center of the
universe, and replacing it with a central fire, around which the rest of
the universe, including the earth, rotated. This hypothesis was
gradually rejected, because the existence of a central fire was never
verified.
Plato (ca 427-347 B.C.) developed the scientific
method, which was inherent in the work of the Greek scientists who
preceded him, and was mastered by all scientists who followed him. In
the Republic, Plato described how, when the senses give the mind
contrary perceptions, the mind is forced to conceptualize an idea which
is intelligible rather than visible. Astronomy compels the soul to look
upward, not in a physical sense, but towards the realm of ideas. The
study of astronomy required that man discover the true motions of the
heavens, rather than merely their motion, as it appeared. “These sparks
that paint the sky, since they are decorations on a visible surface, we
must regard, to be sure, as the fairest and most exact of material
things, but we must recognize that they fall far short of the truth, the
movements, namely, of real speed and real slowness in true number and
in all true figures both in relation to one another and as vehicles of
the things they carry and contain. These can be apprehended only by
reason and thought, but not by sight, or do you think otherwise?”
Further on Plato adds, “It is by means of problems, then, said I, as in
the study of geometry, that we will pursue astronomy too, and we will
let be the things in the heavens, if we are to have a part in the true
science of astronomy and so convert to right use from uselessness that
natural indwelling intelligence of the soul.”
Plato rejected the world view of the oligarchy, who
projected their own evil caprice onto God, and asserted that the
universe was “controlled by a power that is irrational and blind and by
mere chance.” On the contrary, Plato stated that he followed “our
predecessors in saying that it (the universe) is governed by reason and a
wondrous regulating intelligence.” The creator made a universe which is
ordered harmonically, by mind that produces order and arranges each
individual thing in the way that achieves what is best for each and what
is the universal good. Therefore, man can comprehend the universe
through reason.
Plutarch wrote of Plato ” … that Plato in his later
years regretted that he had given the earth the middle place in the
universe which was not appropriate.” Plato laid out a research project
for his students to find “what are the uniform and ordered movements by
the assumption of which the apparent movements of the planets can be
accounted for.”
Heraclides of Pontus, (ca 388-315 B.C.) was a student
of Plato at the Academy in Athens. Born more than 2000 years before the
advent of today’s baby boomer culture, he made a crucial discovery
which all too few baby boomers today have replicated. He discovered that
the entire universe was not rotating around the earth, (and around him,
who was standing on it) as would appear to be the case to one who
believes in sense certainty. Rather, the cause of the rest of the
universe appearing to revolve around the earth was that the earth is,
itself, rotating around its axis. He also discovered that the cause of
the apparently erratic motion of Venus and Mercury is that they are
revolving around the sun. While Heraclides still believed that the Sun
revolved around the Earth, his discovery that Venus and Mercury revolved
around the Sun, set the stage for the later discovery that the Earth
and all the other planets also revolved around the Sun.
Although he wrote numerous dialogues including two
discussing astronomy, only a few remarks by commentators have survived
the dark age, initiated by the Roman Empire, on how he made this
remarkable discovery. We must reconstruct how he could have done it.
What he must have done is conceptualize an idea of the nature of the
Universe, and comprehend that his idea was more real than sense
certainty.
The commentator Aetius reports that Heraclides
thought that each of the innumerable stars in the sky was also a world
surrounded by an atmosphere and an aether. Others, at the time, thought
that the stars were attached to some sort of dome or rings. For example,
Aristotle argued that the stars and sun were objects carried on rings
around the earth at such a high rate of speed that the friction between
the stars and the air caused the sun and stars to give off heat and
light.
Obviously, Heraclides could not have arrived at his
hypothesis based on his senses. (Even in the last few years, when
astronomers have developed experiments to try to determine if other
stars have planets orbiting them, they have still not “seen” any
planets. Instead, they are designing experiments to measure certain
phenomena, such as the distribution of heavy elements in the vicinity of
distant stars, and, then, interpreting the results of their experiments
as proving their hypothesis.) Heraclides must have thought, “If all the
innumerable stars are each a world like our own, and they are at so
immense a distance, that these worlds appear only as small specks of
light in the night sky; why should all of them, and the immense universe
in which they are located, orbit around the one world where he happened
to be located?” Instead, he recognized that the impression which he
received from his senses, that the heavens were rotating around the
earth, could be explained by conceptualizing that the earth was,
instead, rotating on an axis.
One significant anomaly that lead Heraclides to the
discovery that Mercury and Venus revolved around the sun, was that the
brightness of the planet Venus and the rate of it’s change in location,
from night to night, varies dramatically throughout its cycle. It takes
Venus, during the “evening star” part of its cycle, approximately 7
months to rise to its highest position above the western horizon, and
only about 2 months for its descent. At the beginning of this cycle, it
is dim. It becomes progressively brighter, until near the end of its
cycle, it is, by far, the brightest object in the night sky, besides the
moon. During the “morning star” part of the cycle, Venus rises rapidly
to its highest position above eastern horizon in about 2 months, and,
then, decreases in position each night very gradually, taking about 7
months until it disappears entirely under the western horizon. During
the “morning star” part of its cycle, Venus starts out very bright and
becomes progressively dimmer.
Heraclides hypothesized that his observations were a
reflection of how an object rotating around the sun, would appear to an
observer located on the earth, which is revolving on its axis. This is
more easily understood from the following diagram: Draw a circle with a
radius of 3 inches, to represent the orbit of Venus. The center of this
circle represents the sun. Then draw a point to represent the earth,
approximately 4 1/8 inches from the center of the circle. (For purposes
of the diagram, make this dot below the circle.) Heraclides also placed
the planet, Mercury, rotating around the sun in a much smaller circle.
The cycle of Mercury appears similar to that of Venus, to an observer on
earth. However, Mercury is usually much fainter than Venus, and reaches
a maximum altitude in the sky only around 1/3 that of Venus.
In the diagram, the motion of Venus, would be
represented counterclockwise around the circle. (Remember that Kepler’s
discovery of elliptical orbits is almost 2000 years later.) The earth is
rotating, daily, on its axis (counterclockwise in our diagram). The
clearly visible differences in Venus’s brightness are explained by the
dramatic differences in its distance from the earth at different places
in its orbit.
Draw 2 lines from the earth, that are tangent to the
orbit of Venus. At the points of tangency with the circle, the angle
between Venus and the sun is greatest, and Venus will appear the highest
in the night sky to an observer on earth. Draw a line through the sun
and the earth which bisects the orbit of Venus.
Now, conceptualize what an observer standing on the
earth, which is rotating counterclockwise, will see. In left half of the
orbit, Venus appears as the “evening star,” and in the right half it
appears as the “morning star.” Venus travels a far longer distance in
rising to its highest position in the evening sky than in descending,
making its assent take a far longer time than its descent. The opposite
is true for Venus’s appearance in the morning sky.
Heraclides of Pontus’s discovery advanced Plato’s
research project of discovering “what are the uniform and ordered
movements by the assumption of which the apparent movements of the
planets can be accounted for.” He set the stage for Aristarchus
