Julian Schwinger
Julian Seymour Schwinger (; 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. Schwinger was a physics professor at several universities. Schwinger is recognized as an important physicist, responsible for much of modern quantum field theory, including a variational approach, and the equations of motion for quantum fields. He developed the first electroweak model, and the first example of confinement in 1+1 dimensions. He is responsible for the theory of multiple neutrinos, Schwinger terms, and the theory of the spin-3/2 field. Biography Early life and career Julian Seymour Schwinger was born in New York City, to Ashkenazi Jewish parents, Belle (née Rosenfeld) and Benjamin Schwinger, a garment manufacturer, who had emigrated from Poland to the Unite ...

New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States.

Charles M
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age. In some Slavic languages, the name ''Drago (given name), Drago'' (and variants: ''Drago ...

Margaret G
Margaret is a feminine given name, which means "pearl". It is of Latin origin, via Ancient Greek and ultimately from Old Iranian. It has been an English name since the 11th century, and remained popular throughout the Middle Ages. It became less popular between the 16th and 18th century, but became more common again after this period, becoming the second-most popular female name in the United States in 1903. Since this time, it has become less common, but was still the ninth-most common name for women of all ages in the United States as of the 1990 census.

Sam Edwards (physicist)
Sir Samuel Frederick Edwards (1 February 1928 – 7 May 2015) was a Welsh physicist. The Sam Edwards Medal and Prize is named in his honour. Early life and studies Edwards was born on 1 February 1928 in Swansea, Wales, the son of Richard and Mary Jane Edwards. He was educated at the Bishop Gore School, Swansea, and Gonville and Caius College, Cambridge, the University of Manchester, and at Harvard University, in the United States. He wrote his thesis under Julian Schwinger on the structure of the electron, and subsequently developed the functional integral form of field theory. Academic research Edwards's work in condensed matter physics started in 1958 with a paper which showed that statistical properties of disordered systems (glasses, gels etc.) could be described by the Feynman diagram and path integral methods invented in quantum field theory. During the following 35 years Edwards worked in the theoretical study of complex materials, such as polymers, gels, colloids a ...
