Return to the INE Main Page On Geometry and Advanced Energy Conversion
Patrick Bailey, INE President
March 1996 There are quite a few areas in which the idea of the use of a particular geometry has overlapped with the advanced energy areas. Here is a summary of what I can remember off of the top of my head: 1. The Great Pyramid of Giza, Egypt, was built about the same time as the Sphinx, and I think it was definitely built way, way before the other structures there. It has a full base to height ratio of 2 to SQRT(Phi), where Phi is the Golden Ratio and is equal to (1+SQRT(5))/2. That gives an internal triangle with sides of 1-to-SQRT(Phi)-to-Phi. Several experimenters have noticed that four-sided pyramids build with this ratio exhibit strange properties when a base is aligned perpendicular to local magnetic north. I have not seen many papers on exact EM experimental results of the effects of this geometry, and perhaps we should! This would be a great idea for elementary and high school science projects! I also note that when a pyramid of this exact shape is cut along the base and along the edges and unfolded, one gets the Templar Cross. Coincidence?

Golden Ratio

A number often encountered when taking the ratios of distances in simple geometric figures such as the pentagram decagon and dodecagon . It is denoted , or sometimes (which is an abbreviation of the Greek "tome," meaning "to cut"). is also known as the divine proportion, golden mean, and golden section and is a Pisot-Vijayaraghavan constant . It has surprising connections with continued fractions and the Euclidean algorithm for computing the greatest common divisor of two integers Given a rectangle having sides in the ratio is defined such that partitioning the original rectangle into a square and new rectangle results in a new rectangle having sides with a ratio . Such a rectangle is called a golden rectangle , and successive points dividing a golden rectangle into squares lie on a logarithmic spiral . This figure is known as a whirling square . The legs of a golden triangle are in a golden ratio to its base and, in fact, this was the method used by Pythagoras to construct From the definition of the golden mean combined with the above figure

Penrose Tiles Penrose was not the first to discover aperiodic tilings , but his is probably the most well-known. In its simplest form, it consists of 54- and 72-degree rhombi, with "matching rules" forcing the rhombi to line up against each other only in certain patterns. It can also be formed by tiles in the shape of "kites" and "darts" or even by deformed chickens (see the "perplexing poultry" entry below). Part of the interest in this tiling stems from the fact that it has a five-fold symmetry impossible in periodic crystals, and has been used to explain the structure of certain "quasicrystal" substances.

On the side of the box containing a well designed crank operated Tomato Juicer, is printed the motto of today's inspiration: "You Couldn't Get a Better Squeeze". The news for preservers of sweet memories is juicy. Properly applied pressure, sorts waves into preserveable order. The key operating component of the Tomato juicer is a human operated turning spiral helix engraved on a cone vortex. What emerges from the apex of the cone in the shade of living blood, is a harvest of sweetness.

49. Sacred Geometry
The design of TARA chapel is based on the laws of sacred geometry. It'sstrongest components are harmony and the golden mean proportions.
http://homepages.paradise.net.nz/rainersh/sacred_geometry.htm
Sacred Geometry at Tara Sanctuary (The ideas on this Web Page came from a paper called: "The Tara Chapel at Mana is based on Sacred Geometry of Bio Harmonic Architecture" written by the architect of Tara Sanctuary Reinhard Kanuka-Fuchs) The design of TARA chapel is based on the laws of sacred geometry. It's strongest components are harmony and the golden mean proportions. With it's purpose of practising unity in Meditation, Song, Dance and Prayer the harmonic proportions are essential. From the outside harmony is expressed in a multitude of equilateral triangles touching various important points of the building, connecting them. The unity principle can also be demonstrated by a series of concentric circles with the centre of gravity in the centre of the small "soul eye" windows above the annexes The centre of the chapel is a point of gravity, union and essence and it radiates symmetrically out in all directions touching annexes and octagon corners. In the same way bells radiate sound in all directions from the gravity centre of the bell framing. The law of the golden section as expressed in the beauty of the human form, can be seen in various aspects of nature. It is present in the harmonious properties of the human voice as brilliances appearing as high frequencies in the golden mean (Fibonacci) proportions of 3000, 5000, 8000 Hertz. Throughout the building the golden mean ratio of 1:1.618 can be found, pleasing to the eye and soul, our sense of harmony and beauty. It is creating a space of divine acoustics, where the sound seems to ascend. Drawing IV accentuates examples of the golden ratio in various parts of the chapel and bell tower.

CHAPTER XVI: ASCENSION
The Stairs
Eliade remarks that ascension is often seen as a climbing of stairs, and cites the ceremonial staircase in the Orphic and in the Mithraic initiations. He says that stair symbolism is culturally universal and part of the archaic content of the human mind. According to Jung, stairs symbolize the process of psychic transformation in which the contents of the unconscious are brought into conscious awareness. My research suggests that in the humanist symbolism of the painting, Mary's ascension is emphasized by the upper bank of five stairs and by the number of stairs in the staircase. (Fig. 11) Schneider discovered that the angle of the upper five stairs is different from the angle of the lower eight stairs. He believes Titian did this deliberately because the lower stairs are formed of shorter stone rectangles, while the upper stairs are formed of slightly longer ones. (Fig. 11, 34)

The angles are exceptionally significant, for 72 years is 1 degree in the zodiac for our planets recursion through the 12 houses of HOR (Horus). Multiples and divisions of this harmonic number, are used by ALL the major indegenous cultures, from the Myth's of the Egyptians, Vedic Philosophers, to the Edda Runic Bards of Scandinavia, to the Mayan's, the Greeks, and the K'mer's of Cambodia, one universal geometry and number system unites them, as we will show in articles to be. But this sequence also enables us to make the Unified Field Cartography system, for navigation in Earths magnetic field Icosahedron, as you will find at the Geodyseum of Earths Biosphere (GEB) site, and to turn time into a Dodecahedron. This establihses an extraterrestrial Unified Field Universal Navigation system.

"To see the world in a grain of sand, and heaven in a wildflower.
(William Blake)
The Golden Section "I came across a defintion of the Golden Mean which states that it is the unity that includes both what is perceived as well as the perceiver." "There are two ways [and the Golden Proportion is the only number for which this is true] mathematically, by which you can place the Golden Mean between those two points. The lesser in relation the the greater in the Golden Mean can signify that the outer is the greater and the inner is the lesser, or it can signify that the inner is the greater and the outer is the lesser. But the 'mean' is a flucutation in between those two things." So the Yin and the Yang are as the proportions of the Golden mean unto each other, and thus chase each other dynamically in asymetrical equilibrium.

A particularly elegant manifestation of the golden mean is in other also determinedby the golden ratio Robert Lawler, Sacred geometry, Thames and Hudson, 1982.
http://home.earthlink.net/~klogw/TheGoldenMean.htm
The Golden Mean
A Pictorial Essay
Scholars of the occult have speculated that the Golden Mean was of supreme importance to the ancient Pythagoreans as a key to unlocking the mysteries of the universe. One of these mysteries is that from the Golden Mean the Pentagram can be constructed by means of compass and straight edge alone. The following pictorial essay shows the classical construction used to obtain the segment length which is in golden ratio proportion to a segment of unit length. The Pentagram is then easily constructed from these two lengths. Can you see how? An interesting application of the Golden Mean is the construction of the logarithmic spiral. The logarithmic spiral is found throughout nature from conch shells to the pattern of seeds in sun flowers to the pattern of lines in the feathers of peacocks. The spiral is constructed by starting with two golden mean rectangles and successively adjoining squares to the preceding construction. Can you see how?
A particularly elegant manifestation of the Golden Mean is in the design of Japanese sand gardens. As can be seen in the diagram below three rocks are laid out collinear on a line such that the line segments they define are in golden ratio proportion to each other. Although not shown in the diagram, the two lines of rocks are at an angle to each other also determined by the golden ratio. All around the rocks sweeping to the coping tile around the garden is elegantly raked sand, almost giving the rocks the appearance of islands rising up out of tranquil waters. The entire effect is that of correct proportion achieving balance and tranquility.

Phi
The Golden Mean The Golden Mean (or Golden Section), represented by the Greek letter phi, is one of those mysterious natural numbers, like e or pi, that seem to arise out of the basic structure of our cosmos. Unlike those abstract numbers, however, phi appears clearly and regularly in the realm of things that grow and unfold in steps, and that includes living things.
The decimal representation of phi is 1.6180339887499... . Pure Math
Proportion is the relationship of the size of two things.
Arithmetic proportion exists when a quantity is changed by adding some amount. Geometric proportion exists when a quantity is changed by multiplying by some amount. Phi possesses both qualities.
If you study the Fibonacci series and the Golden Rectangle carefully, you will eventually realize that phi + 1 = phi * phi.
The resulting proportion is both arithmetic and geometric. It is thus perfect proportion; you could think of it as the place on some imaginary graph where the curved line of multiplication crosses the straight line of addition.

Traditional Sacred geometry. The Fibonacci series can be used to defineboth the golden mean and Pi, the two main irrational numbers.
http://www.dimensional.com/~ahm/matrix/SpSt/geometry.htm
Human Spiritual Structure: Sacred Geometry
  • Notes from Nothing:
  • This is supposed to be the basic geometry of the universe, the underlying patterns of all existance. The following derivation is said to parallel the creation of the world given in Genesis. First there is the void. Then spirit reaches out in six directions, up, down, back, forth, right and left, creating three axis' which allows measurement and movement. Filling out the axis's results first in a square and then in an octogaon, two base to base pyramids. (In planar figure this also gives the hexagon, and by reprojecting into 3 dimensions the cube.) Straight lines are male, curves female, so spining the octagon to create a sphere generates female from male. Spirit moved to the surface of the sphere and then began to make more spheres. In planar form six more can fit around the circle (Spirit rested on the seventh day). In space perhaps there are also six, one centered out each axis? These are all interlocking, i.e. the center of each is on the circumferance of the others. By rotation this generates a tube torus? which appears to be a torus with a zero inner radius, e.g. a donut without a hole. This is used to generate a figure inside a tetrahedron which in turn generates the various Hebrew letters, by projection back to a plane. [Stan Tenen]. The Greek and Arabic letters can also be formed by a similar process.

    http://www.geoman.com/geomantext.html
    G E O M A N A T O M Y James L. Fournier
    The new Vitruvian Man I discovered, which I have called Geoman, adds two of the three fundamental polygonal shapes in plane geometry, the equilateral triangle, and the pentagram, both in the golden mean relationship to the same circle represented with the square in Leonardo daVinci's Vitruvian Man.
    In Leonardo's drawing there are two of the four simplest shapes in plane geometry. These are the circle representing unity, or one, and the square representing four. I had noticed that the relationship between the circle and the square in Leonardo's drawing is the golden mean ratio. Thus the length of one side of the square is 1.618 times the radius of the circle. I found this by measuring Leonardo's drawing, but D'Arcy Thompson had also demonstrated by statistical analysis that on average the distance from the ground to a person's navel is the golden mean of their overall height. I also knew that the navel, our center, the center that we grow from, is also our center of mass, the point which we would spin about weightless in space, which is also the center that we find when we meditate and find our "center" (yellow in the diagram).
    Each of the three shapes shares the same edge length as the square, and thus each is in the golden mean relationship to the radius of the circle. The key to the success of the diagram is that the tip of the equilateral triangle protrudes through the base of the square, counter to the medieval teaching that the arm span is equal to the diagonal to the feet. Instead, the two points where the triangle meets the ground represent the centers of the feet, and the tip of the triangle represents the pointed toes as if in a pirouette.
