of Khufu as an astronomical observatory. Located on the Giza plateau, the
Great Pyramid is stunning in the precision of its construction, a construction
which could only have been meant for astronomical study. It is located
precisely at 30° latitude, and is more accurately aligned to the four cardinal
points than modern structures built to the same end. Within that alignment,
the shafts built into the Pyramid, at crucial angles, allow for precise
observations of key stars, such as Sirius, the North Star, and Orion's brightest
star, as they transit the celestial meridian.

For the builders of the Great Pyramid to have accomplished such a task, the
understanding of the regular motions of the stars and the celestial geometry of
sphaerics had to have existed long before such an undertaking. The Pyramid
Texts carved on the smaller pyramids of Saqqara, describe important
astronomical cycles as myths in which, for example, figures such as Osiris
and Isis are represented by the constellation Orion and the star Sirius,
respectively. And, while carved in stone during the Old Kingdom, the origin
of the Pyramid Texts is presumed to be much older.

Precession of the Eqinoxes
The “precession of the equinoxes” is an observed effect caused by the
slow, top-like wobble of the north-south axis of the Earth over a period
of 25,900 years. Hence, the “North Star”—which is, by definition, the
star to which the axis points—shifts over that period. Today it is
Polaris, but during Egypt’s Old Kingdom it was Alpha Draconis. This
shifting celestial geometry (which is 1-degree every 72 years) results in
another important change in observations: The constellation of the
Zodiac which rises just before the sun on the vernal equinox, which is
called the heliacal constellation, also changes slowly over time, as if the band of the Zodiac were sliding
backwards against the fixed annual position of the equinoctial sun. This effect is known as the “precession of
the equinoxes.”
Left: Earth’s axis of rotation itself
rotates around the “pole ofthe
ecliptic.”
The 12 constellations of the Zodiac are the ones which follow the same path as the sun along the ecliptic, and Egyptian
mythology and religion are filled with images of them. The dominance of a particular image, such as the scorpion, the
bull, or the ram, often corresponds to the historical period in which that constellation was the heliacal constellation. For
example, the death of Osiris, which Freemasons and Synarchists make a great mystical to-do over, can be seen simply as
the disappearance of the constellation Orion from the sky, on the vernal equinox, which occurred around 6700 B.C.E.

The Legcy of Plato
A physical concept of magnitude was already fully developed by the circle associated with Plato, and expressed most
explicitly in the Meno, Thaetetus, and Timaeus dialogues. Plato and his circle demonstrated this concept, pedagogically,
through the paradoxes that arise when considering the uniqueness of the five regular solids, and the related problems of
doubling a line, square, and cube. As Plato emphasized, each species of action generated a different species of magnitude.
He denoted such species by the Greek word dunamis, the root of the English ‘dynamo’ translated as ‘power.’ The meaning
of the term dunamis is akin to Leibniz’s use of the German word Kraft.
That is, a linear magnitude has the power to doubled a line. whereas only a magnitude
of a different species has the power to double a square, and a still different species has
the power to double a cube. In Bernhard Riemann's terminology,there magnitudes are
called, respectively simply-extended, doubly-extended, and triply-extended. Plato's
circle emphasized that magnitudes of lesser extension lacked the potential to generate
magnitudes of higher extension, creating, conceptually, a succession of higher powers.
Plato's circle also emphasized, that this succession of magnitudes of higher powers, was
generated by a succession of different types of action. Specifically, a simply-extended
magnitude was produced from linear action, doubly-extended magnitudes from circular
action, and triply-extended magnitudes from extended circular action, such as the
rotational actions that produce a cone, cylinder, or torus. Plat's collaborator, Archytas,
demonstrated that the magnitude with which a cube is doubled, is not generated by
circular action, but by extended circular action, i.e., conic sections.
—Bruce Director
Plato (427-347 B.C.E)
Archytas's Construction For
Doubling the Cube
Archytas developed a construction to find tow geometric means between two magnitudes. AC and AB. Magnitude AS is
drawn as the diameter of circle ABC; AB is a chord of the circle. Using this circle as the base, generate a cylinder. The
circle is then rotated 90 degrees about AC, Si it is perpendicular to the plane of circle ABC; it is then rotated about point
A, to form a torus with nil diameter. (The intersection fo the torus and the cylinder produces a curve of double curvature.)
Chord AB is extended until it intersects the perpendicular to AC at point D; this forms triangle ACD, which lies in plane
of circle ABC, AB, and AC Triangle ACD is then rotated around AC, producing a cone. The cone, torus, and cylinder all
intersect at point P. Perpendicular PM is then dropped from P along the surface of the cylinder, until it intersects circle
ABC at point M; this forms right triangle AMP. Through this construction, a series of similar right triangles (only partially
shown) is generated, which produces the continued proportion, AB:AM::AM:AP::AP:AC. Thus, AM and AP are shown to
be the two geometric means between magnitudes AC and AB.

The Platonic Solids

Among the many startling discoveries of the application of universal physical
principles to the organization of the visible world found in the scientific investigations
of Plato and his associates, was the recognition of the unique constructability of the
five regular (Platonic) solids. The most important aspect of this discovery did not lie in
the visible world, however, but in the necessary implications for the existence of what
Bernhard Riemann would call the “complex domain” two millennia later.
The proof that no other regular solids but
these—the pyramid, cube, octahedron,
dodecahedron, and icosahedron—can be
constructed in visible space, was tantamount
to the assertion that, contrary to textbook
Euclideanism or the dead world of Isaac
Newton, physical space was not “empty,” but
instead shaped by unseen boundary
conditions inherent in the possibilities of
physical action. What appear to be the
axioms, definitions, and postulates of
mathematics, must yield to the causal
relations of physics; in fact, the very proof of
the uniqueness of the Platonic solids—one of
the greatest achievements of Greek geometry,
which required the development of a theory

based.
Although Plato presents these issues directly
in his Timaeus, they are also embedded at the
heart of the Republic, in the twinned
metaphors of The Cave and the Divided Line.
Here, we see that what we know truly, we
know metaphorically—but only by reference to an unseen Power which animates and unifies
the more immediate aspects of our experience.

Mathematical Models vs. Truth
In The New Astronomy, Johannes Kepler demonstrated that Ptolemy's,
Copernicus's and Tycho Brahe's planetary systems gave exactly the same
computational results, so there was no way to tell which one was true. Despite
the fact that all three were radically different, there was a common error that
pervaded them. All three were mathematical models for the purpose of
predicting the motions of the planets, while making no attempt to discover the
physical causes. Consequently, all three imposed the mathematics of perfect
circles and uniform motion onto the planetary orbits, when the physical
obserervations showed otherwise. Kepler's investigation of physical
causalityâÄ”led him to the discovery that the planetary orbits were elliptical.

sun moving around it in perfect circles. (b) The Copernican system, with the

center, and all the planets move about the sun in perfect circles, while the sun
moves about the Earth in a perfect circle.

Kepler’s Physics of Non-Constant Change
Kepler’s revolution was, to derive the principles of planetary motion from physical principles, not mathematical
ones. He conceived that the sun moved all the planets by a virtue (power) emanating from it, whose intensity
diminished with distance. Thus, if the planet were moving in an orbit in which its distance from the sun varied, it
would physically speed up and slow down as it moved around the sun.(a) The planet at P1 is closer to the sun
A, than at P2. Thus, as the planet moves from P1 to P2, it is always slowing down. This means that equal
portions of the planet’s period do not correspond to equal distances along its orbital path. Kepler showed that
these equal areas swept out by a line connection the planet to the sun.
(b) Kepler measured these areas.
The area swept out as the planet
moves from P1 to P2 is the white
area (P1-P2-A). That area is
measure by the portion of the
circle, P1-B-P2. minus the triangle
P2-B-A. The area of that triangle is
the distance BA times the height
P2-N. But, the line P2-N, as
Nicolaus of Cusa showed, is
incommensurable with the arc P1P2. Thus, the principle of nonuniform planetary motion is dependent on magnitudes which are not susceptible of precise calculation. This
gave rise to the famous “Kepler problem”: If Kepler knew where the planet had been, he could calculate what
portion of the orbit (time) had elapsed. But, owing to the transcendental relationship between the line and
curve, he could not precisely calculate where the planet would be when an equal amount of time would have
elapsed. Kepler called on future geometers to solve this problem, which provoked Leibniz to develop the
calculus.

(c) Keplers’s initial discovery of the “equal areas, equal times” principle was developed under the assumption
that the orbit was circular, with the sun at an eccentric point. After comparing his results to the true
observations, Kepler found he was 8′ of arc off. It is a tribute to Kepler’s genius, that he saw that this small
discrepancy was a matter of principle, not simply a minor error. He subsequently revised all his work, and
discovered that the planetary orbits were ellipses with the sun at one focus.
(d) Kepler’s diagram from the New Astronomy. The dotted curve is an ellipse. As you can see, this ellipse is
very close to a circle, but as Cusa has forecast in On Learned Ignorance, there is no perfectly circular motion in
the created world.

‘Follow the Drinking Gourd’
“When the sun comes back
And the first quail calls,
Follow the Drinking Gourd.
For the old man is a-waiting for to carry you to freedom,
If you follow the Drinking Gourd. ...”
This haunting folk song, first sung by slaves in Alabama and Mississippi before
the Civil War, was rediscovered in 1912 by folklorist H.B. Parks, who overheard
an African-American man in North Carolina singing it. The words were a puzzle,
but the singer flatly refused to explain thir meaning. A year later, Parks heard
the song again in Louisville, Kentucky—but again, the singer kept mum. It was
only after 1918 that he learned from a Black man in Texas, that the lyrics gave
escaping slaves directions to find their way north to freedom. They would
always travel under the cover of night. By finding the “Drinking Gourd” in the sky
—the constellation we call the Big Dipper, which points to the North Star,
Polaris—they would follow a route north (described in “code” in the song), along
first the Tombigbee River, then the Tennessee, and finally crossing the Ohio
River into the free state of Illinois.
The idea of using the vast, unfettered expanse of
the starry heavens to find one's way to freedom,
became more than just a navigational “trick,” but a
metaphor for the quest for freedom. Frederick Douglass, the great leader of the
movement to free the slaves, named his newspaper The North Star. He understood
profoundly that science means the liberation of man; only if your oppressors can keep
you ignorant, can they control you.
As most people know, the slaves were helped along their way by the “Underground
Railroad” of people who would feed and safehouse them, and direct them on to the
next “station.” The most famous “conductor” on the “railroad” was Harriet Tubman,
known as the Moses of her people. Frederick Douglass wrote to her in 1868: “I have
had the applause of the crowd and the satisfaction that comes of being approved by
the multitude, while the most you have done has been witnessed by a few trembling,

the multitude, while the most you have done has been witnessed by a few trembling,
scared, and foot-sore bondsmen and women, whom you have led out of the house of
bondage, and whose heartfelt 'God bless you' has been your only reward. The
midnight sky and the silent stars have been the witnesses of your devotion to freedom
and your heroism.”
Tubman, herself a
slave in Maryland, had
escaped to freedom at
the age of 28, with
only the North Star as
her guide. She then
helped more than 300
others to do the same,
telling them:
“Children, if you are
tired, keep going; if
you are scared, keep going; if you are hungry; keep going;
if you want to taste freedom, keep going.” She kept a sixshooter under her skirt, to provide a little encouragement to

another step. Tubman summed up her life's work: “On my
Underground Railroad I nebber run my train off de track
and I nebber los' a passenger”—a quote which was inscribed on a plaque in her honor by the citizens of Auburn, New
York, at the court house in Cayuga County, where she died in 1913.
