 Julian Schwinger - Biography
Schwinger was particularly pleased by an anticipation, early in 1957, of the existence of two different neutrinos associated, respectively, with the electron and the muon.
Schwinger's policy of finding theoretical virtues in experimentally unknown particles has culminated recently in a revived concern with magnetically charged particles, which may also be involved in the understanding of strong interactions.
Schwinger is a member of the latter body, and a sponsor of the Bulletin of the Atomic Scientists.

 Julian Schwinger, Nobel Laureate, UCLA Faculty (UCLA Gateway)
Julian Schwinger was a professor in UCLA's department of physics from 1972 until his death in 1994.
"Julian was a gentle, cultivated man and one of a handful of scientists whose magnificent contributions made science the great intellectual adventure of the 20th century," said David Saxon, UCLA professor emeritus of physics and former University of California president.
The theoretical achievements of Schwinger and Feynman in the late 1940s and early 1950s provoked a revolution in theoretical physics (quantum field theory) and laid the foundations for the spectacular progress made in physics since that time.

In 1945 Schwinger joined the faculty of Harvard University, where in 1947 he became one of the youngest full professors in that university's history.
Schwinger's equations not only saved Dirac's theory but served to unite electromagnetic theory with quantum mechanics to form the new field of quantum electrodynamics.
Schwinger completed his work unaware that Feynman and Tomonaga were independently working on the same problem.

 Julian Schwinger and the Source Theory
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.
From 1943 to 1946, Schwinger was a member of the wartime staff of the Radiation Laboratory at the Massachusetts Institute of Technology.

An earlier volume, Julian Schwinger, the Physicist, the Teacher and the Man (World Scientific), is a compilation of tributes delivered at various memorial symposia by friends and former students and edited by Jack Ng.
The Schwinger theory of 1948, while adequate for its original purpose, was, like every first invention, relatively crude and could not easily be pushed to higher order.
To this period belong the Schwinger action principle and the extensive use of Green's functions and functional techniques that are now part of the standard literature.

The first two-thirds of the book, which deals with Schwinger's early remarkable career in nuclear physics, his profound work on waveguides and synchrotron radiation during World War II, his conquest of quantum electrodynamics, and his groundwork on what became the standard model, is hardly mentioned.
Schwinger likewise had little interest in such subjects as constructive field theory and asymptotic freedom.
Julian Schwinger's legacy lies primarily in the foundations of fundamental physics: his operator formalism of quantum field theory, combined with a renormalization scheme; and his motivations and justifications in searching for a new scheme--the source theory--that has great impact on the conception of effective field theories.

 Julian Schwinger
Julian Seymour Schwinger (February 12, 1918 -- July 16, 1994) was an American theoretical physicist.
He was jointly awarded the Nobel Prize in Physics in 1965 for his work on quantum electrodynamics (QED), along with Richard Feynman and Shinichiro Tomonaga.
Having supervised more than seventy doctoral dissertations, Schwinger is known as one of the most prolific graduate advisors in physics.

I wrote to Schwinger but he replied that his visit to London was to get some rest and have a holiday.
Then, Salam and P. Matthews met Schwinger from the plane, with a large hired limo, and took him to his hotel, where he was left alone for three days.
Schwinger balked at this; it was a legal requirement in those days that clubs offering topless waitresses can admit only members and guests.

A deep and provocative thinker, Schwinger left his indelible mark on all areas of theoretical physics; an eloquent lecturer and immensely successful mentor, he was gentle, intensely private, and known for being "modest about everything except his physics".
From it, one can get a glimpse of Julian Schwinger, the physicist, the teacher, and the man. Altogether, this book is a must for all physicists, physics students, and others who are interested in great legends.

Schwinger was one of the most important and influential scientists of the twentieth century.
The list of his contributions is staggering, from his early work leading to the Schwinger action principle, Euclidean quantum field theory, and the genesis of the standard model, to later valuable work on magnetic charge and the Casimir effect.
"Julian Schwinger deserves to be remembered as a great scientist for his many brilliant scientific achievements.

 Schwinger Multichannel Method   (Site not responding. Last check: 2007-11-05)
The Schwinger Multichannel method is a modification of Julian Schwinger's original variational method for scattering problems.
An important feature of the original Schwinger method that is preserved in the SMC method is that all required matrix elements are independent of the long range behavior of the trial functions.
Because both the number of such elementary quantities and the work needed to combine them into final matrix elements grow rapidly with the size of the molecule and the amount of detail included in the calculation, high-performance computing is essential to practical applications.

Novel elements of the approach include the immediate inference of Maxwell’s equations from Coulomb’s law and (Galilean) relativity, the use of action and stationary principles, the central role of Green’s functions both in statics and dynamics, and, throughout, the integration of mathematics and physics.
The text for the graduate classical electrodynamics course was left unfinished upon Julian Schwinger’s death in 1994, but was completed by his coauthors, who have brilliantly recreated the excitement of Schwinger’s novel approach.

Chronologically, the first critical experiment was the discovery by John Nafe, Edward Nelson, and I. Rabi that the hyperfine separation of atomic hydrogen was different from that predicted by the Dirac theory of the electron.
Schwinger invited me to lunch and asked me searching questions about the reliability of the experimental hyperfine anomaly.
It is worth noting, however, that the experiment of Willis Lamb was motivated, at least in part, by the belief that there should be higher-order corrections to the hydrogen spectrum, a subject much discussed in the Oppenheimer group with which Lamb worked in the 1930s.

Schwinger's book about electrodynamics is a book that in my opinion is better and also more advanced then Jackson's Electrodynamics.
One may call Schwingers introduction of the magnetic charge an annoyance, but in my opinion, he is making an excellent point about how physics should be done: open-minded and always marking where gaps might be, that needs to be filled later.
Schwinger is indeed an exception and his book on top of everything covers more then Jackson as well.
