A second or third gen PAL VHS dub of a vintage original off-air NTSC VHS tape, then captured and compressed and found on a torrent site. squashed, re-compressed and converted for YouTube. all sorts of obvious video and audio problems, but at least it's here, a special treat from the past. anyone with better source, please drop a comment.
Richard Phillips Feynman (May 11, 1918 - February 15, 1988; IPA: /ˈfaɪnmən/) was an American physicist known for expanding the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and particle theory. 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 widely-used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams.
He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster. In addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology (creation of devices at the molecular scale). He held the Richard Chace Tolman professorship in theoretical physics at Caltech.
Feynman was a keen popularizer of physics in both his books and lectures, notably a 1959 talk on top-down nanotechnology called There's Plenty of Room at the Bottom and The Feynman Lectures on Physics. Feynman is also known for his semi-autobiographical books Surely You're Joking, Mr. Feynman! and What Do You Care What Other People Think?, and through books about him, such as Tuva or Bust!. He was also known as a prankster, juggler, a proud amateur painter, and a bongo player. Richard Feynman was regarded as an eccentric and a free spirit. He liked to pursue multiple seemingly independent paths, such as biology, art, percussion, Maya hieroglyphs, and lock picking. Freeman Dyson once wrote that Feynman was "half-genius, half-buffoon", but later revised this to "all-genius, all-buffoon". During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.
