There is a mathematician named Douglas R Hofstader, another one named Sheldon Katz, both rather interesting in their own way.

The former is the author of several books. Godel Esher Bach is most likely the most well known of them.

The latter Sheldon H. Katz is an American mathematician, specializing in algebraic geometry and its applications to string theory. In 1973 Katz won first prize in the U.S.A. Mathematical Olympiad (Wikipedia). This is him talking about something I understand some of the words but not in that order, it is way over my head.
