Richard Feynman Lecture: Entropy, Past and Future

Filmed at Cornell University in November, 1964, the Nobel Prize winning physicist delivers a lecture on the distinction between the past and the future, the law of entropy and the history of the universe.

One of the greatest physicists of all time, Feynman (1918 - 1988) has been credited with pioneering the field of quantum computing and introducing the concept of nanotechnology. He was a keen popularizer of physics through books and lectures.

“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.” - Feynman in Appendix F to the Rogers Commission report, which investigated the Challenger disaster.
