Steven Weinberg Totally Explained

Everything about Steven Weinberg totally explained

Steven Weinberg (born May 3, 1933) is an American physicist, and Nobel laureate in Physics for his contributions with Abdus Salam and Sheldon Glashow to the unification of the weak force and electromagnetic interaction between elementary particles.

Biography

Steven Weinberg was born in 1933 in New York City, the son of Jewish parents Frederick and Eva Weinberg. He graduated from Bronx High School of Science in 1950 and received his bachelor's degree from Cornell University in 1954, living at the Cornell branch of the Telluride Association. He left Cornell and went to the Niels Bohr Institute in Copenhagen where he started his graduate studies and research. After one year, Weinberg returned to Princeton University where he earned his Ph.D. in Physics in 1957, studying under Sam Treiman.

Academic career

After completing his Ph.D., Weinberg worked as a professor at Columbia University (1957-1959) and UC-Berkeley (1959-1966) and did research in a variety of topics of particle physics, such as the high energy behavior of quantum field theory, symmetry breaking, pion scattering, infrared photons and quantum gravity. It was also during this time that he developed the approach to quantum field theory that's described in the first chapters of his book The Quantum Theory of Fields and started to write his textbook Gravitation and Cosmology. Both textbooks, perhaps especially the second, are among the most influential texts in the scientific community in their subjects.
   In 1966, Weinberg left Berkeley and accepted a lecturer position at Harvard. In 1967 he was visiting professor at MIT. It was in that year at MIT that Weinberg proposed his model of unification of nuclear weak forces and electromagnetism. An important feature of this model is the prediction of the existence of another interaction, besides electromagnetic, between leptons, known as neutral current. This proposal is now known as the Standard Model of elementary particle physics and is the highest cited theoretical work ever in high energy physics as of 2007. The Standard Model is the best description of Nature at scales from about a few GeV to about 200 GeV.
   After the seminal work on the unification of weak and electromagnetic interactions, Steven Weinberg continued his work in many aspects of particle physics, quantum field theory, gravity, supersymmetry, superstrings and cosmology. In 1973, he proposed the theory of Strong Interations without the so called Higgs boson (as was earlier thought) and explicitly conjectured the confinement of quarks and gluons. It is of special importance that in 1979 he pioneered the modern view on the renormalization aspect of quantum field theory that considers all quantum field theories as effective field theories and changed completely the viewpoint of previous work (including his own) that a sensible quantum field theory must be renormalizable. This approach allowed the development of effective theory of quantum gravity, low energy QCD, heavy quark effective field theory and other developments, and it's a topic of considerable interest in current research. Of a more speculative nature, it's also of present interest his idea on the existence of new strong interactions -- a proposal dubbed "Technicolor" by Leonard Susskind -- because of its chance of being observed in the LHC as an explanation of the hierarchy problem.
   After the discovery of the neutral currents -- for example the discovery of the inferred existence of the Z boson --, Steven Weinberg was awarded the Nobel Prize in Physics in 1979.
   Weinberg became Higgins Professor of Physics at Harvard University in 1973, a position he held until 1982 when he moved to the University of Texas at Austin as the Jack S. Josey-Welch Foundation Regents Chair in Science and founded the Theory Group of the Physics Department.
   His influence and importance in science can be somewhat gauged by the fact that Prof Weinberg is often among the top scientists with highest research impact indices, such as the h-index and the creativity index.

Other intellectual legacy

Besides his scientific research, Steven Weinberg has been a prominent public spokesman for science, testifying before Congress in support of the Superconducting Super Collider, writing articles for the New York Review of Books, and giving various lectures on the larger meaning of science. His books on science written for the public combine the typical scientific popularization with what is traditionally considered history and philosophy of science and atheism.
   Weinberg was a major participant in what is known as the Science Wars, standing with Paul R. Gross, Norman Levitt, Alan Sokal, Lewis Wolpert, and Richard Dawkins, on the side arguing for the hard realism of science and scientific knowledge and against the constructionism proposed by such social scientists as Stanley Aronowitz, Barry Barnes, David Bloor, David Edge, Harry Collins, Steve Fuller, and Bruno Latour.
   Weinberg is also known for his support of Israel. While this isn't extraordinary in itself, he, like many American Jews, supports Israel from a liberal point of view. He wrote an essay titled "Zionism and Its Cultural Adversaries" to explain his views on the issue.
   Weinberg has canceled trips to universities in the United Kingdom because of British boycotts directed towards Israel. He has explained:
� "Given the history of the attacks on Israel and the oppressiveness and aggressiveness of other countries in the Middle East and elsewhere, boycotting Israel indicated a moral blindness for which it's hard to find any explanation other than antisemitism.

His views on religion were expressed in a speech from 1999 in Washington, D.C.: � "Religion is an insult to human dignity. With or without it you'd have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion."

He attended and was a speaker at the symposium on November 2006.

Personal

He is married to Louise Weinberg and has one daughter, Elizabeth.
