What did Luis Alvarez invent?

Answer 1

Alvarez won the 1968 Nobel prize for for Physics "the discovery of a large number of resonance states, made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Specifically, his research made it possible to record and study the short lived particles created particle accelerators. During World War II, Alvarez was a key participant in the Manhhaton Project including Project Alberta on the dropping of the bomb, and in war projects in general. He flew as a scientific observer of the Atomic Bombinh of Heroshima on The Great Artiste. Alvarez and his student Lawrence Johnston designed the exploding-bridgewire detonators for the spherical implosives used on the Trinity and Nagasaki bombs. He additionally did important work relating to radar and aviation, and designed a system by which airplanes could land safely in low visibility conditions, useful both to bombers and commercial aviation. After the war he went on to invent the synchrotron. Alvarez also proposed a jet-recoil theory for the Kennedy assassination to explain why John F. Kennedy's head jerked backwards if Lee Harvey Oswald, shooting from behind the president, was the assassin.
