He assisted in the development of the atomic bomb during World War II and became known to a wide public in the 1980s as a member of the Rogers Commission, the panel that investigated the Space Shuttle Challenger disaster.
Feynman had his revenge a few years later, when Heisenberg concluded an entire book in cosmic rays with the phrase: "such an effect is not to be expected according to Vallarta and Feynman." When they next met, Feynman asked gleefully whether Vallarta had seen Heisenberg's book. It was not just a facility at mathematics (though it had become clear ...
that the mathematical machinery emerging from the Wheeler–Feynman collaboration was beyond Wheeler's own ability).
So, take a stroll down memory lane to remember all of our past Word of the Year selections.
; May 11, 1918 – February 15, 1988) was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model.
As a child, he had a talent for engineering, maintained an experimental laboratory in his home, and delighted in repairing radios.
