Tetrahedron: The Transmitting Differential Tetrahedron Displacement:
"If A force sends facet A toward vertex a at some rate, X, as that with which force D withdraws facet D away from vertex d, while concurrently a force C sends facet C toward vertex c at a rate entirely independent of rate X, while a force B withdraws facet B away from vertex b at the same rate, Y, as that of force C, then the tetrahedron a,b,c,d will remain the same size and will seem superficially to travel in a line of direction which coincides with the intersection of two planes: one through a,c perpendicular to d,b, and one through d,b perpendicular to a,c.
“(I discovered this differential displacement coupling unlike forces in November 1955 while in Minn. Minn. - RBF)”
