"but even the greatest theoretical physicists of the twentieth century including Einstein, Fermi, Feynman and Bohr were really known for their physical intuition than for formidable mathematical prowess" Nonsense. Feynman, for example, was famous for his ability to formulate and to solve mathematical problems in hours that his colleagues had spent months working on. How is this in Scientific American? Not worth reading.
