I have an email friend called EO Thorpe. There's a guy you should interview, by the way, EO Thorpe. EO Thorpe lives in California. He was a physicist turned mathematician. Then he taught for a while in universities and, while he was getting his degree, was at the time when this blackjack thing I told you about in Los Alamos was invented. And a teacher of his told him about it. And he was going to Las Vegas or somewhere with his wife and his teacher gave him this and Thorpe became interested. And Thorpe invented card-counting. He was the inventor of card-counting. And he wrote a book, I think it was called Beat the Dealer. And there's a movie, 21, which is kind of based on this stuff. And then he got out of physics and ran money. And he's a money manager for… he used to run billions of dollars in university endowments. I've never met him but we email a lot. He's an extraordinarily interesting guy.
