¶ Dimpling Effect (3)
Index Entry
Dimpling: Dimpling Effect: (3) Icosahedron:
“An icosahedron, it now has a North and South Pole … and we have the two equinoctial limits of what we call the Tropic of Cancer and the Tropic of Capricorn. So I press on one of its vertexes, five legs out of thirty locally dimple. So it literally is dimpled then and there is a lot of space inside the icosahedron not filled in. As I get higher and higher triangulation… as I get into the geodesics, the higher the frequency of the geodesic-modular subdivision of the icosahedron-- and the more local the dimpling. The legs are spread out. There is a hexagon or a pentagon that refuses to yield in tension, so that the legs have to yield in compression, bending, and she pops inwardly. So the higher the frequency, the more local the dimple.”
