One of my favorite stories about Einstein is that he was being interviewed, and at the end the reporter said, "If I have any follow-up questions, can I call you?" And Einstein went over to the bookcase and looked up his phone number [in a phone book] and gave it to the reporter. And the reporter said, "You're the smartest man in the 20th century -- how do you not know your own phone number?" And he said, "Vy fill my mind with such useless information if I know vere I can find it?" Was that why he was able to come up with the theory of relativity -- he wasn't filling his mind with useless information?
