Mathematics genius John Nash recalls his bout with schizophrenia (the subject dramatized in the Oscar-winning film "A Beautiful Mind"). Nash is joined by his wife, Alicia; son John Stier; colleagues; and author Sylvia Nasar, who wrote the book from which the movie was adapted. They (and narrator Liev Schreiber) recall Nash's prodigious intellect, arrogant demeanor and odd behavior. He developed his "equilibrium point" theory as a student, but then lost his own equilibrium. It would take 30 years, but the theory would come to revolutionize economics and win him the Nobel Prize. And Nash would regain his mind.
