who is john nash?

Forbes Nash, Jr. (born June 13, 1928), is an American mathematician and economist whose works in game theory, differential geometry, and partial differential equations provided insight into the forces that govern chance and events inside complex systems in daily life. His theories are still used today in market economics, computing, accounting and military theory. Serving as a Senior Research Mathematician at Princeton University during the later part of his life, he shared the 1994 Nobel Memorial Prize in Economic Sciences with game theorists Reinhard Selten and John Harsanyi.

Nash is also the subject of the movie, A Beautiful Mind, which was nominated for eight Oscars (winning four). The film was based on the biography of the same name, and focuses on Nash's mathematical genius and his struggle with schizophrenia.
