Well...this woman I work with is always going off about U2 and this and that. Usually it's annoying, but incredibly in this case it was helpful. First useful thing she's done in quite a while believe me (Freak). Whowudathunkit. As for the next question, the only mathemiticians I have heard of are Hawking, Einstein and buddy from A Beautiful Mind (Nash). Of course the first two are actually physicists.
