Abstract: | Julian Schwinger’s influence on twentieth-century science is profound and pervasive. He is most famous for his renormalization
theory of quantum electrodynamics, for which he shared the Nobel Prize in Physics for 1965 with Richard Feynman and Sin-itiro
Tomonaga. This triumph undoubtedly was his most heroic work, but his legacy lives on chiefly through subtle and elegant work
in classical electrodynamics, quantum variational principles, proper-time methods, quantum anomalies, dynamical mass generation,
partial symmetry, and much more. Starting as just a boy, he rapidly became one of the preeminent nuclear physicists in the
world in the late 1930s, led the theoretical development of radar technology at the Massachusetts Institute of Technology
during World War II, and soon after the war conquered quantum electrodynamics, becoming the leading quantum-field theorist
for two decades, before taking a more iconoclastic route during the last quarter century of his life. |
