Not really into biographies but the anecdotes around the man are astonishing; bongo player, Mayan numbering decipherer- there's a story that he fixed a car he borrowed from looking at it and figuring out how it worked! The man seems to have been genuinely fascinated with the world and it'd be incredible to hear his take on it- the lectures and diagrams are amazing in presenting complex information with simplicity and elegance. Rare soul indeed!
