Steven Weinberg Biography and Timeline

Birth

Is born in New York City and later develops an early interest in theoretical physics.

Copenhagen Study

Begins a year of graduate study at the Institute for Theoretical Physics in Copenhagen and starts research in physics.

Role range: 1954-1955

Cornell Degree

Receives his undergraduate degree from Cornell University.

Columbia Research

Begins postdoctoral research at Columbia University after completing his doctorate.

Role range: 1957-1959

Doctorate

Receives his PhD from Princeton University for work applying renormalization theory to strong-interaction effects in weak processes.

Berkeley Research

Moves to Berkeley and conducts research across high-energy physics, weak currents, broken symmetries and scattering theory.

Role range: 1959-1966

Berkeley Faculty

Joins the University of California, Berkeley faculty as an assistant professor.

Berkeley Professorship

Becomes a full professor at the University of California, Berkeley.

A Model of Leptons

Publishes A Model of Leptons, giving a compact electroweak gauge theory with spontaneous symmetry breaking and a scalar field.

Higgs Boson

Uses spontaneous symmetry breaking in A Model of Leptons to construct a unified electroweak theory incorporating a Higgs-type scalar field.

Standard Model

Steven Weinberg and Abdus Salam incorporated the Higgs mechanism into Glashows electroweak theory

Weak Mixing

Relates electromagnetic and weak interactions through a common gauge framework whose parameters include the weak mixing angle.

MIT Appointment

Joins the Massachusetts Institute of Technology faculty and continues research in particle theory.

Role range: 1969-1973

Gravitation and Cosmology

Publishes Gravitation and Cosmology, presenting general relativity and cosmology in a form that becomes influential in graduate physics education.

Harvard Professorship

Becomes Higgins Professor of Physics at Harvard University.

Role range: 1973-1982

Higgs Boson

Sees neutral-current observations strengthen the electroweak theory that he had formulated using spontaneous symmetry breaking.

Neutral Current Confirmation

Sees weak neutral-current observations provide decisive experimental support for the electroweak theory.

Higgs Boson

Shares the Nobel Prize in Physics for the electroweak theory, which incorporates the symmetry-breaking mechanism later tested through Higgs-boson measurements.

Nobel Prize

Shares the Nobel Prize in Physics with Sheldon Glashow and Abdus Salam for contributions to electroweak unification.

University of Texas

Joins the University of Texas at Austin as Jack S. Josey-Welch Foundation Chair in Science and builds a prominent theory group.

Role range: 1982-2021

Cosmological Constant Problem

Weinberg reviews the enormous mismatch between simple quantum-vacuum estimates and the observed small cosmological constant, defining a central theoretical problem for dark energy.

Dreams of a Final Theory

Publishes Dreams of a Final Theory, explaining the search for deeper unification in fundamental physics to a broad audience.

Quantum Theory of Fields

Publishes the first volume of The Quantum Theory of Fields, synthesizing modern quantum field theory for advanced researchers and students.

Vacuum Energy and Cosmic Acceleration

Weinberg examines the cosmological constant and vacuum energy after the discovery of acceleration, emphasizing the unresolved theoretical origin of the observed energy scale.

Cosmology

Publishes Cosmology, presenting the theoretical foundations and observational framework of modern cosmological physics.

Death

Dies in Austin after a career that reshaped particle physics, quantum field theory and modern cosmology.
