Tetrahedron: Inside-out Tetrahedron Begins to Grow:
“Remember that when we took a tetrahedron and moved any of its faces around their opposite vertexes (i.e., contract their center-of-gravity lines-- from centers of area of faces to opposite vertexes); that the faces are reduced symmetrically while the angles are (changed ?). Finally the opposite face coincides with the vertex and the face planes are (co ?) existant with a common convergent point and no volume. If this is moved an inside-out tetrahedron begins to grow. So I see that energetic geometry is one up on the topologists because it understands the dynamic significance of the implicit 2 and the inherent spin.”
