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.

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. degree in Physics in 1957, studying under Sam Treiman.
After completing his Ph.D., Weinberg worked as a professor at Columbia University (1957-1959) and University of California, 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.[1] It was also during this time that he developed the approach to quantum field theory that is described in the first chapters of his book The Quantum Theory of Fields [2] 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 electromagnetism and of nuclear weak forces (such as those involved in beta-decay and kaon-decay) [3]. This model is now known as the electroweak unification theory. An important feature of this model is the prediction of the existence of another interaction mechanism between leptons, known as neutral current and mediated by the Z boson. The experimental discovery of this Z boson was one verification of the electroweak unification. The paper by Weinberg in which he presented this theory is one of the highest cited theoretical work ever in high energy physics as of 2006[4].
After his 1967 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 the years after 1967, the full Standard Model of elementary particle theory was developed through the work of many contributors. In it, the weak and electromagnetic interactions already unified by the work of Weinberg, Abdus Salam and Sheldon Glashow, are further unified with the strong interactions, in one overarching theory. One of its fundamental aspects was the prediction of the existence of the Higgs boson. In 1973 Weinberg proposed a modification of the Standard Model which did not contain that model's fundamental Higgs boson.
Weinberg became Higgins Professor of Physics at Harvard University in 1973.
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[5]. This approach allowed the development of effective theory of quantum gravity[6], low energy QCD, heavy quark effective field theory and other developments, and it is a topic of considerable interest in current research.
In 1979, after the experimental discovery of the neutral currents -- i.e. the discovery of the inferred existence of the Z boson --, Steven Weinberg was awarded the Nobel Prize in Physics together with Abdus Salam and Sheldon Glashow for developing their theory of electroweak unification.
In 1982 Weinberg 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.
There is current (2008) interest in Weinberg's 1976 proposal of the existence of new strong interactions[7] -- a proposal dubbed "Technicolor" by Leonard Susskind -- because of its chance of being observed in the LHC as an explanation of the hierarchy problem.
Steven Weinberg's influence and importance is confirmed by the fact that he is frequently among the top scientists with highest research impact indices, such as the h-index and the creativity index.[8][9][10][11][12][13][14][15]
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 is not 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:
His views on religion were expressed in a speech from 1999 in Washington, D.C.:
He attended and was a speaker at the Beyond Belief symposium on November 2006.
He is married to Louise Weinberg and has one daughter, Elizabeth.
The honors and awards that Prof Weinberg received include
A Designer Universe?, critically discussing the possibility of the intelligent design of the universe, is based on a talk given in April 1999 at the Conference on Cosmic Design of the American Association for the Advancement of Science in Washington, D.C.
