Sheldon Lee Glashow Net Worth

Sheldon Lee Glashow was born on December 05, 1932 in New York City, New York, United States, United States, is Physicist. Sheldon Lee Glashow is an American theoretical physicist who received a share of the 1979 Nobel Prize for Physics for his contribution to developing the electroweak theory, which explains the unity of electromagnetism and the weak force. Along with his high profile academic career as the Metcalf Professor of Mathematics and Physics at Boston University, he is also a member of the Board of Sponsors for the ‘Bulletin of the Atomic Scientists.’ The son of Jewish immigrants from Russia, he was born in New York City and raised in a middle-class home. Both of his parents, who themselves had been unable to get a good education, were adamant that their children should receive university education. He was bright and scientifically inclined from a young age and attended the Bronx High School of Science where he became friends with future scientists Gary Feinberg and Steven Weinberg. There was no doubt in his mind that one day he would grow up to be a scientist. After receiving a Bachelor of Arts degree from Cornell University and a Ph.D. degree in physics from Harvard University, he ventured into an academic career and spent several years in the Harvard physics department in diverse posts. It was in the 1960s that he began his work on electroweak unification models, which ultimately won him the Nobel Prize.

Sheldon Lee Glashow was born in New York City, to Jewish immigrants from Russia, Bella (née Rubin) and Lewis Gluchovsky, a plumber. He graduated from Bronx High School of Science in 1950. Glashow was in the same graduating class as Steven Weinberg, whose own research, independent of Glashow's, would result in Glashow, Weinberg, and Abdus Salam sharing the 1979 Nobel Prize in Physics (see below). 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. Afterwards, Glashow became a NSF fellow at NORDITA and joined the University of California, Berkeley where he was an associate professor from 1962 to 1966. He joined the Harvard physics department as a professor in 1966, and was named Eugene Higgins Professor of Physics in 1979; he became emeritus in 2000. Glashow has been a visiting scientist at CERN, and professor at Aix-Marseille University, MIT, Brookhaven Laboratory, Texas A&M, the University of Houston, and Boston University.


In 1961, Glashow extended electroweak unification Models due to Schwinger by including a short range neutral current, the Z0. The resulting symmetry structure that Glashow proposed, SU(2) × U(1), forms the basis of the accepted theory of the electroweak interactions. For this discovery, Glashow along with Steven Weinberg and Abdus Salam, was awarded the 1979 Nobel Prize in Physics.


In collaboration with James Bjorken, Glashow was the first to predict a fourth quark, the charm quark, in 1964. This was at a time when 4 leptons had been discovered but only 3 quarks proposed. The development of their work in 1970, the GIM mechanism showed that the two quark pairs: (d.s), (u,c), would largely cancel out flavor changing neutral currents, which had been observed experimentally at far lower levels than theoretically predicted on the basis of 3 quarks only. The prediction of the charm quark also removed a technical disaster for any quantum field theory with unequal numbers of quarks and leptons — an Anomaly — where classical field theory symmetries fail to carry over into the quantum theory.


In 1973, Glashow and Howard Georgi proposed the first grand unified theory. They discovered how to fit the gauge forces in the standard model into an SU(5) group, and the quarks and leptons into two simple representations. Their theory qualitatively predicted the general pattern of coupling constant running, with plausible assumptions, it gave rough mass ratio values between third generation leptons and quarks, and it was the first indication that the law of Baryon number is inexact, that the proton is unstable. This work was the foundation for all Future unifying work.


Glashow shared the 1977 J. Robert Oppenheimer Memorial Prize with Feza Gürsey.


In 2003 he was one of 22 Nobel Laureates who signed the Humanist Manifesto.
