> He is also a human calculator with tremendous aptitude for arithmetics. Even if this is true (and I'm not sure it is--Feynman had good intuition about a lot of things, but "human calculator with tremendous aptitude for arithmetics" seems more like a description of John Von Neumann or Norbert Wiener), I think it's orthogonal, so to speak, to the ability to live with not knowing the answers to questions.
