Dyson is best known for demonstrating in 1949 the equivalence of the formulations of quantum electrodynamics that existed by that time – Richard Feynman's diagrams, on the one hand, and, on the other, the operator method developed by Julian Schwinger and Sin-Itiro Tomonaga.

File: Richard Feynman Nobel. jpg | Richard Feynman ( 1918-1988 ): developed the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, awarded the Nobel Prize in Physics in 1965 with Julian Schwinger and Sin-Itiro Tomonaga, developed the Feynman diagram representing subatomic particle behavior.

Based on Bethe's intuition and fundamental papers on the subject by Sin-Itiro Tomonaga, Julian Schwinger, Richard Feynman and Freeman Dyson, it was finally possible to get fully covariant formulations that were finite at any order in a perturbation series of quantum electrodynamics.

Sin-Itiro Tomonaga, Julian Schwinger and Richard Feynman were jointly awarded with a Nobel prize in physics in 1965 for their work in this area.

An unusually exotic theory of sonoluminescence, which has received much popular attention, is the Casimir energy theory suggested by noted physicist Julian Schwinger and more thoroughly considered in a paper by Claudia Eberlein of the University of Sussex.

The CPT theorem appeared for the first time, implicitly, in the work of Julian Schwinger in 1951 to prove the connection between spin and statistics.

Later important contributors to twentieth century mathematical physics include: Satyendra Nath Bose, Julian Schwinger, Sin-Itiro Tomonaga, Richard Feynman, Freeman Dyson, Hideki Yukawa, Roger Penrose, Stephen Hawking, Edward Witten, and Rudolf Haag.

This pair-creation amplitude was first calculated by Julian Schwinger in 1951.

Other scientists whose careers began at the Molecular Beam Laboratory included Norman Ramsey, Julian Schwinger, Jerome Kellogg and Polykarp Kusch.

The theoretical physicist, Julian Schwinger, who used Green's functions in his ground-breaking works, published a tribute, entitled " The Greening of Quantum Field Theory: George and I ," in 1993.

One way of describing the divergences was discovered in the 1930s by Ernst Stueckelberg, in the 1940s by Julian Schwinger, Richard Feynman, and Shin ' ichiro Tomonaga, and systematized by Freeman Dyson.

Julian Schwinger discovered a relationship between zeta function regularization and renormalization, using the asymptotic relation:

This problem of systematically handling the infinities of quantum field theory to obtain finite physical quantities was solved for QED by Richard Feynman, Julian Schwinger and Sin-Itiro Tomonaga, who received the 1965 Nobel prize for these contributions.

In physics, the Schwinger model, named after Julian Schwinger, is the model describing 2D Euclidean quantum electrodynamics with a Dirac fermion.

A more conceptual argument was provided by Julian Schwinger in 1950.

This argument is due to Julian Schwinger.

Glashow received a Bachelor of Arts degree from Cornell University in 1954 and a Ph. D. degree in physics from Harvard University in 1959 under Nobel-laureate physicist Julian Schwinger.

Daniel Kleitman, who was also a doctoral student of Julian Schwinger, is his brother-in-law, through Joan's other sister.

In particle physics, it occurs in a formula by Julian Schwinger, giving an exact result for the pair production rate of a Dirac electron in a uniform electric field.

Julian Schwinger published a useful paper in 1949 that reduced the necessary calculations to Bessel functions, for which there were tables.

The first Capitan was (' Tan ) Julian Flores.

Dashwood wrote sensitively and evocatively about the Cook Islands in magazines and books (' South Seas Paradise ') under the pseudonym Julian Hillas.

Year 33 ( XXXIII ) was a common year starting on Thursday ( link will display the full calendar ) of the Julian calendar.

The estimated year of the Crucifixion is AD 33, by two different groups, and originally as AD 34 by Isaac Newton via the differences between the Biblical and Julian calendars and the crescent of the moon.

Year 33 BC was either a common year starting on Saturday, Sunday or Monday or a leap year starting on Sunday ( link will display the full calendar ) of the Julian calendar ( the sources differ, see leap year error for further information ) and a leap year starting on Saturday of the Proleptic Julian calendar.

In 1931, for example, Julian held the non-stop non-refueling aviation endurance record with a flight of 84 hours and 33 minutes.

( Gregorian ), which is the same day as one of those supported by other twentieth commentators, Friday April 3, AD 33 ( Julian ).

Petitions asking for a jail term for Norristown attorney Julian W. Barnard will be presented to the Montgomery County Court Friday, it was disclosed Tuesday by Horace A. Davenport, counsel for the widow of the man killed last Nov. 1 by Barnard's hit-run car.

Both the BIH scale and A. 1 was defined by an epoch at the beginning of 1958: it was set to read Julian Date 2436204. 5 ( 1 January 1958 00: 00: 00 ) at the corresponding UT2 instant.

Perisapora was captured and destroyed by Emperor Julian in 363, but speedily rebuilt.

Their most famous battle against Rome took place in Argentoratum ( Strasbourg ), in 357, where they were defeated by Julian, later Emperor of Rome, and their king Chnodomarius was taken prisoner to Rome.

As the Battle of the Frigidus, which terminated this campaign, was fought at the passes of the Julian Alps, Alaric probably learned the weakness of Italy's natural defences on its northeastern frontier at the head of the Adriatic.

It was at Anah that the emperor Julian met the first opposition on his disastrous expedition against Persia ( 363 ), when he got possession of the place and transported the people ; and there that Ziyad and Shureih with the advanced guard of Ali's army were refused passage across the Euphrates ( 36 / 657 ) to join Ali in Mesopotamia ( Tabari i. 3261 ).

Like many ancient historians, Ammianus had a strong political and religious agenda to pursue, however, and he contrasted Constantius II with Julian to the former's constant disadvantage ; like all ancient writers he was skilled in rhetoric, and this shows in his work.

Julian of Eclanum was bishop of the town during the 5th century.

Most recently, Mike Piazza, then of the New York Mets, was hit in the head by a pitch from Julian Tavarez of the St. Louis Cardinals on September 10, 2005.

Pompey's plan was to allow Caesar's infantry to advance, have his cavalry attack and push back the numerically inferior Julian horses, and then attack Caesar's infantry from behind.

According to the Julian calendar however, the date was either 29 June ( according to Le Verrier's chronological reconstruction ) or possibly 7 June ( according to Drumann / Groebe ).

Due to the change from the Julian calendar to the Gregorian calendar, Bealltainn in Scotland was commonly celebrated on 15 May while in Ireland " Old Beltane " or " Old May " began about the night of 11 May.

The 2011 winner was The Sense of an Ending by Julian Barnes.

The term clade was introduced in 1958 by Julian Huxley after having been coined by Lucien Cuénot in 1940, cladistic by Cain and Harrison in 1960, and cladist ( for an adherent of Hennig's school ) by Mayr in 1965.

The week cycle was not even interrupted when 10, 11, 12, or 13 dates were skipped when the Julian calendar was replaced by the Gregorian calendar by various countries.

In 1934, then enrolled as a graduate student at King's College London, he wrote his Ph. D. thesis on Trade and War in the Eastern Seas, 1803-1810, which was awarded the Julian Corbett Prize in Naval History for 1935.

The term was coined in 1958 by the biologist Julian Huxley.

A few days later, Julian was married to Helena, the last surviving sister of Constantius.

However, on account of the immediate Sassanid threat, Constantius was unable to directly respond to his cousin ’ s usurpation other than by sending missives by which he tried to convince Julian to resign the title of Augustus and be satisfied with that of Caesar.

However, by the time he reached Mopsuestia in Cilicia, it was clear that he was fatally ill and would not survive to face Julian.

Apparently, realising his death was near, Constantius had himself baptised by Euzoius, the Semi-Arian bishop of Antioch, and then declared that Julian was his rightful successor.
