User gluonium recently turned us on to the interview shown at the start of this excellent Horizon special. Here's the whole thing.
: Richard Phillips Feynman was an American physicist known for expanding the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and particle theory.
As well as being an inspirational lecturer, bongo player, notorious practical joker, and decipherer of Maya hieroglyphs, Richard Feynman was regarded as an eccentric and a free spirit. He liked to pursue multiple seemingly independent paths, such as biology, art, percussion, and lock picking. Freeman Dyson once wrote that Feynman was "half-genius, half-buffoon", but later revised this to "all-genius, all-buffoon".
For his work on quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga; he developed a way to understand the behavior of subatomic particles, by using pictorial tools that later became known as Feynman diagrams.
Feynman was a keen and influential popularizer of physics in both his books and lectures, notably a seminal 1959 talk on top-down nanotechnology called There's Plenty of Room at the Bottom and The Feynman Lectures on Physics, a three-volume set which has become a classic text. Known for his insatiable curiosity, wit, brilliant mind and playful temperament, he is equally famous for his many adventures, detailed in his books Surely You're Joking, Mr. Feynman! and What Do You Care What Other People Think?, and in books about him, such as Tuva or Bust!
