"Genius: The Life and Science of Richard Feynman"

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,^[2] and introducing the concept of nanotechnology (creation of devices at the molecular scale).^[3] 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.
