“…Now I have a fourth ball that comes around in there and it nests on top of the first three. Now it can no longer even evolute and, for the first time, all motion is blocked. This makes a tetrahedron. This is where stability begins. The tetrahedron is where the triangle gives what we call a ‘structure,’ or something that doesn’t change its pattern any more. It was dynamic up to that time.”
