Murray Gell-Mann, Nobel Prize-winning physicist who named quarks, dies at 89

Murray Gell-Mann, the Nobel-winning physicist who brought order to the universe by helping discover and classify subatomic particles, has died. He was 89.Video: Murray Gell-Mann on ditching what everybody knows Read moreGell-Mann died on Friday at his home in Santa Fe, New Mexico. His death was confirmed by the Santa Fe Institute, where he held the title of distinguished fellow, and the California Institute of Technology, where he taught for decades.

The cause was not disclosed.Gell-Mann transformed physics by devising a method for sorting subatomic particles into simple groups of eight, based on electric charge, spin and other characteristics. He called his method the “eightfold way” after the Buddhist Eightfold Path to enlightenment.Gell-Mann also developed the theory that identified “quarks”, indivisible components of Earth’s matter that make up protons, neutrons and other particles.

Experiments confirmed the existence of quarks, and these objects now form the basis for our physical understanding of the universe, Caltech said in a statement.In a quirk typical of Gell-Mann’s approach to science, he chose the name “quark” for a line from James Joyce’s Finnegans Wake: “Three quarks for Muster Mark.

”“It would be hard to overestimate the degree to which Murray dominated theoretical particle physics during his heyday in the 1950s and 1960s,” said John Preskill, Richard P Feynman professor of theoretical physics at Caltech.“He contributed so many deep ideas that drove the field forward, many of which are just as relevant today.

Born and raised in New York City, Gell-Man received his bachelor’s degree in physics from Yale in 1948 and his PhD from Massachusetts Institute of Technology in 1951.In later years, Gell-Mann became interested in the issues of complexity at the heart of biology, ecology, sociology and computer science.

He co-founded the Santa Fe Institute to study complex systems and authored the 1994 book The Quark and the Jaguar to present his ideas to a general audience.He is survived by his children, Nicholas Gell-Mann and Elizabeth Gell-Mann, and stepson Nicholas Southwick Levis, according to the Caltech statement.
