“Born in the Far Rockaway
section of New York City, on May 11, 1918, Feynman was the descendant of Russian
and Polish Jews who had emigrated to the United States late in the 19th century.
He studied physics at the Massachusetts Institute of Technology, where his undergraduate
thesis (1939) proposed an original and enduring approach to calculating forces
in molecules. Feynman received his Ph.D. at Princeton University in 1942. At
Princeton, with his adviser, John Archibald Wheeler, he developed an approach
to quantum mechanics governed by the principle of least action. This approach
replaced the wave-oriented electromagnetic picture developed by James Clerk
Maxwell with one based entirely on particle interactions mapped in space and
time. In effect, Feynman's method calculated the probabilities of all the possible
paths a particle could take in going from one point to another.” source...
