Descartes: (1596-1650.)
“Descartes is the first of record to have discovered that the sums of the angles of a polyhedron is always 720° less than the number of vertexes times 360°. Descartes did not equate the 720° with the tetrahedron, nor with the one unit of energy quantum which it vectorially constitutes. He did not recognize the difference between the visibly definite system and the invisibly finite universe, which is one finite invisible tetrahedron outwardly and one finite invisible tetrahedron inwardly.”
