Julian Seymour Schwinger ( / ˈʃwɪŋər /; February 12, 1918 – July 16, 1994) was a Nobel Prize -winning American theoretical physicist. He is best known for his work on quantum electrodynamics (QED), in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.
Apr 1, 2002 · Julian Schwinger (1918–1994) was a legendary figure in the history of fundamental physics. While still a teenager, he amazed leaders of theoretical physics in the US with his prodigious theoretical insights. As a young Harvard professor, he quickly became the supreme intellectual leader in quantum field theory (QFT) and particle physics.
The Schwinger's quantum action principle is a variational approach to quantum mechanics and quantum field theory. This theory was introduced by Julian Schwinger in a series of articles starting 1950. Approach. In Schwingers approach, the action principle is targeted towards quantum mechanics.

Jul 16, 1994 · However, partly because the electron’s magnetic moment proved to be somewhat larger than expected, the theory had to be reformulated. Julian Schwinger solved this problem in 1948 through “renormalization” and thereby contributed to a new quantum electrodynamics.
When quantum field theory became the mainstream approach for the description of particle interactions and quantum chromodynamics became accepted by most physicists in the early 1970s, Schwinger did not change his philosophical perspective and continued to develop his source theory with the collaboration of his students.
Aug 14, 2003 · Subsequently, he presented the most complete formulation of quantum field theory and laid the foundations for the electroweak synthesis of Sheldon Glashow, Steven Weinberg, and Abdus Salam, and he made fundamental contributions to the theory of nuclear magnetic resonance as well as many-body theory and quantum optics. Schwinger also developed a ...
