Julian Schwinger and the Source TheoryResources with Additional Information Julian S. Schwinger received the
1965 Nobel Prize in Physics for his "fundamental work in quantum
electrodynamics, with deep-ploughing consequences for the physics of
elementary particles". "The theoretical achievements of Schwinger
and [Richard] Feynman
in the late 1940s and early 1950s ignited a revolution in quantum field
theory and laid the foundations for much of the spectacular progress
that has been made during the ensuing four decades in understanding
the fundamental forces of nature. Although many others also contributed,
it was Julian who made the initial breakthrough and led this development
in its early stages. ...
From 1943 to 1946, Schwinger was a member of the wartime staff of the Radiation Laboratory at the Massachusetts Institute of Technology. At MIT he played a leading role in the development of the radar that was crucial to the Allied war effort. After the war, Schwinger accepted an associate professorship at Harvard and became a full professor in 1947 at age 29. Between 1948 and 1950, Schwinger published the monumental papers on quantum electrodynamics for which he later shared the Nobel Prize. In 1972, Julian moved to the Department of Physics at UCLA... . During the late sixties he began a total reconstruction of the quantum field theory to which he had contributed so fundamentally. This new theory, which he named source theory, was his response to the failures of the then existing (operator) field theory to describe the new experimental discoveries in high energy particle physics. ... In the end there was almost no frontier of theoretical physics to which he did not make important contributions: nuclear, particle, and atomic physics, statistical mechanics, classical electrodynamics, and general relativity. ... In addition to the Nobel Prize, Schwinger received numerous international awards and honors for his research. A member of the National Academy of Science for more than forty-five years, in 1949 he was awarded the academy's Nature of Light Prize. In 1951, Schwinger shared the first Albert Einstein Prize with mathematician Kurt Godel. The same year he received the Columbia University Medal for his work on quantum electrodynamics. In 1964, President Lyndon Johnson awarded him the newly created National Medal of Science." – Edited excerpts from Julian Seymour Schwinger,
