Nonfiction works have examined MIT, its history, and its various subcultures. In addition to books like "Nightwork," which recount the institute's hacking tradition, Benson Snyder's "The Hidden Curriculum" (1970) describes the state of MIT student and faculty psychology in the late 1960s. Noted physicist and raconteur Richard Feynman built up a collection of anecdotes about his MIT undergraduate years, several of which are retold in his loose memoir "Surely You're Joking, Mr. Feynman!" Some of this material was incorporated into Matthew Broderick's film "Infinity" (1996), in addition to Feynman stories from Far Rockaway, Princeton University, and Los Alamos, New Mexico.
