1937–2007 · Quantum field theory, particle physics
American theoretical physicist, one of the founding fathers of modern quantum field theory. His work on false vacuum decay and instantons became a cornerstone for understanding quantum processes in the early universe. A brilliant lecturer and mentor, he shaped generations of physicists with his legendary course at Harvard.
Biography
He graduated from Caltech and received his PhD from Harvard, where he spent his entire career as a professor. Among his students were future Nobel laureates. His lectures were renowned for their depth and wit.
Key discoveries
False vacuum theory — the possibility of spontaneous tunneling from a metastable state to the true vacuum. Instantons — non-perturbative solutions of field equations
describing quantum transitions. Coleman-Mandula theorem on symmetries in quantum field theory.
💡 Coleman was known for his wit and profound lectures; his quantum field theory course at Harvard was attended by future Nobel laureates.
"He held that a lack of complete confusion about quantum mechanics indicates a lack of understanding."
