If a division is to be made been mathematics and physics, I would class Von Neumann as a mathematician who did vital work in physics, along with Gauss and Riemann. No doubt, one of the greatest intellects in history. The best theoretical physicists this century I would say are Dirac and Einstein, closely followed by Von Neumann. -- Charles Francis email@example.com
