The problem-solving tools that he invented—including pictorial representations of particle interactions known as Feynman diagrams—permeated many areas….

Schwinger was a child prodigy, publishing his first physics paper at age In his last publications, Schwinger proposed a theory of sonoluminescence as a long distance quantum radiative phenomenon associated not with atoms, but with fast-moving surfaces in the collapsing bubble, where there are discontinuities in the dielectric constant.

Sir Isaac Newton, English physicist and mathematician, who was the culminating figure of the scientific…. Robert Oppenheimerand was later appointed to a position at Purdue University. In the s, Schwinger formulated and analyzed what is now known as the Schwinger modelquantum electrodynamics in one space and one time dimension, the first example of a confining theory.

He attended the City College of New York as an undergraduate, and received his doctorate from Columbia University in where he studied under I. National Academy of Sciences In fact, most of his knowledge of physics at that time was gathered outside the formal educational system. He tried applying his knowledge as a Nuclear Physicist to electromagnetic engineering problems, and arrived at results on nuclear scattering.

Our editors will review what you’ve submitted, schwlnger if it meets our criteria, we’ll add it to the article. During his tenure at Harvard, Schwinger worked on various aspects of modern theoretical physics and until mid s, was considered an authority on that subject.

Although he did not bother to publish many of them, some were later printed by his students. His father, Benjamin Schwinger, was a successful clothing manufacturer. He gave elegant proofs for the spin-statistics theorem and the CPT theoremand noted that the field algebra led biographh anomalous Schwinger terms in various classical identities, because of short distance singularities. Inhe was promoted to the post of full professor.

It is a complete description of the interaction…. His fascination for physics grew while going through Encyclopedia Britannica at a very young age. Wikiquote has quotations related to: He received his regular academic appointment in the summer of as an instructor of physics at the Purdue University, Indiana. In he became the Eugene Higgins professor of physics at Harvard.

Ultimately, he left Purdue to join Harvard University as an Associate Professor and remained there until Please try again later.

Born a child progeny, Julian became interested in physics at an early age. Schwimger using this site, you agree to the Terms of Use and Privacy Policy. By the age of sixteen he had published his first paper on physics. You can make it easier for us to review and, hopefully, publish your contribution by keeping a few points in mind.

However, he did not immediately get his degree. As a famous physicist, Schwinger was often compared to another legendary physicist of his generation, Richard Feynman. His findings helped to bring about new dimension to the jukian field theory.

February 12 Both his father and his mother’s parents were prosperous clothing manufacturers, although the family business declined after the Wall Street Crash of Please note that our editors may make some formatting changes or correct spelling or grammatical errors, and may also contact you if any clarifications are needed.

Schwinger made a quantum electrodynamical calculation that made use of the notions of mass and charge renormalizationjjlian brought agreement between theory and experimental data. This was extended by his student Sheldon Glashow into the accepted pattern of electroweak unification.

These were attended by a selected group of colleagues. In later years, Schwinger has followed his own advice about the practical importance of a phenomenological theory of particles. He married in He not only developed the formalism of the new QED in several fundamental papers, but had also made them more useful for practical calculations.

## Julian Seymour Schwinger

Julian published his first paper in physics in at the age of sixteen and by the age of seventeen he was schwjnger advanced calculations. He attempted to formulate a theory of quantum electrodynamics with point magnetic monopolesa program which met with limited success because monopoles are strongly interacting when the quantum of charge is small.

Schwinger discovered that neutrinos come in multiple varieties, one for the electron and one for the muon.

He formulated the theory of renormalization and posited a phenomenon of electron-positron pairs known as the Schwinger effect. He was only twenty-one years old then. The theory, known as quantum electrodynamics QEDhad its foundations in the discoveries of Dirac, Heisenberg, and Pauli.

Consequently, Schwinger began to apply his understanding of radiation to quantum physics. I have experienced it in editors’ rejection of submitted papers, based on venomous criticism of anonymous referees.

However, the war ended before, he could finish the series. He also acted as academic advisor to around 73 doctoral students and 20 post doctoral students.

Medal of Honor Recipients. He received his B. He died from pancreatic cancer on July 16, at his home in Los Angeles. He left more than seventy students, shwinger whom he continued to influence modern physics long after his death.
