Einstein and Hawking (no s) were giants of their field, published papers that turned all other accepted science on its head, and have basic physical phenomenon of the Universe named after them, but they were of surprisingly limited in their knowledge of other fields. Whereas NdT will expound on absolutely any topic with the complete certainty that he is a fucking expert, even if he only just now inferred the existence of the thing from the question he is presently being asked. He is a Mycroftian megabrain of galactic proportions, a fact he appreciates better than anyone else.
