Steve Hsu has a link to a fascinating documentary on John Von Neumann. It’s definitely worth watching. Von Neumann is probably the last great polymath. Mathematician Paul Halmos laments that Von Neumann perhaps wasted his mathematical gifts by spreading himself too thin. He worries that Von Neumann will only be considered a minor figure in pure mathematics several hundred years hence. Edward Teller believes that Von Neumann simply enjoyed thinking above all else.
