Steven Weinberg

Steven Weinberg (May 3, 1933 – July 23, 2021) was an American theoretical physicist whose work on the unification of the electromagnetic and weak nuclear forces formed a cornerstone of the Standard Model of particle physics. Weinberg shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Abdus Salam for their independent contributions to the electroweak theory, which predicted the existence of the W and Z bosons later confirmed experimentally. A professor at Harvard and later the Josey Regental Chair in Science at the University of Texas at Austin from 1982 onward, he advanced quantum field theory through seminal textbooks and research on cosmology, including effective field theories and grand unified theories. Weinberg also authored popular works such as The First Three Minutes (1977), explaining Big Bang nucleosynthesis, and expressed staunch materialist views, arguing that a complete scientific understanding of the universe renders supernatural explanations superfluous.

Steven Weinberg was born on May 3, 1933, in New York City to Frederick Weinberg, a court stenographer, and Eva Weinberg, a homemaker, both Jewish immigrants from Europe. As their only child, Weinberg developed an early interest in science around age 16 after receiving a chemistry set from a cousin, which sparked his curiosity in experimentation.
