I was out at Berkeley last week. There was a conference there that they hold every year. It’s very interesting. Professor Nonaka and some other people get together. And there’s a woman there who’s part of that team called Charlene Demuth, who has a book on comparing Nobel Prize winners, and people who almost won the Nobel Prize. So if you try to look at those groups, and ask, “Well, what’s the critical factor between those who win it, and those who almost win it?”, well, you have to eliminate intelligence, because they’re all super smart. 
   And you have to eliminate education and background, because they’re the same sort of people. 
   So the biggest factor is just plain luck. Who worked on what experiment? He over there studies plutonium, and you over here study phlogisten. He wins and you lose. So clearly some things are just luck.
