Well, after learning about Frank Chester's take on a particular geometric form, the heptahedron (a seven-sided form), my attitude isn't "so what?" anymore. Now, its "so . . . wonderful!"
Frank Chester is an educator and sculptor who took it upon himself to investigate the seven-sided form. His line of inquiry started with pondering this motif, one of seven seals that Rudolf Steiner designed.
Mr. Chester wanted to take this two-dimensional seven-sided image and make it three-dimensional. He thought about what it would be as a platonic form. Not satisfied by the existing models for what a seven- sided form would look like, he tinkered with clay and string and straws and wire and paper and bubbles and whatever models he could make, until he discovered a shape more simple and elegant than any presented before. The implications of his discovery of this heptahedron affect notions in mathematics, geology, architecture, medicine, and more; much more than is touched upon by this article.
This shape has seven sides: each side has exactly the same surface area. There are four equal triangles and three equal four-sided shapes that look like kites. In the picture (below left) of his cardboard model, you see one of the triangles, and two of the kite-shaped sides. Mr. Chester has found that he can draw all the surfaces of this shape, flattened, by using two sizes of circles; the arc tracings on the sides of this model show the remnants of that drawing process. The relationship between the size of the two circles is the Golden Mean, a ratio that artists and scientists have found governs many natural items such as the proportions of a leaf or of the human body.
One of the things he did was to dip the edges-only model into soapy liquid and then blow air into it through a straw to make a bubble, a process which rounds all the lines and surfaces, making the shape organic. Frank Chester compared his rounded seven-sided shape with a drawing he found on the web of the left and right ventricles of the heart. The right ventricle fits around the left ventricle.
The heart is not a pump. Instead the heart is a streaming device, and in the left ventricle, the spin of fluid is captured and twirled back on itself. In this way, the heart acts as a brake. The prime reason for this braking is balance. The heart is a balancing organ.
The idea that the heart is a pump has dominated medicine for centuries. Yet at the apex of the left ventricle of the heart, the bottom point, the tissue is paper thin, not strong enough to enclose fluid under pressure. With the vortex model for understanding the motion of blood within the heart, one can see how this part of the heart never receives dangerous pressure, which it would, if the heart were indeed a pump. Other researchers have been able to show with cameras that the blood courses through the blood vessels of the human embryo, before the heart is even formed. Something else is moving the blood. This is another reason Frank Chester believes that the heart is not a pump.
He has found that the heart is a streaming organ that is itself formed by a reversing, swirling stream. The blood enters the left ventricle in a clockwise spiral. By the time it moves out of the left ventricle, it is spinning in a counterclockwise motion. It reverses direction inside of the left chamber.
