Murray Gell-Mann

American theoretical physicist who devised the quark model, which explained the organization of subatomic particles and became the basis of the Standard Model of particle physics. He also introduced many other concepts in particle physics.

Biography

Born in 1929 in New York City. A child prodigy, he entered Yale University at the age of 15 and received his doctorate from the Massachusetts Institute of Technology in 1951. He worked at Princeton, the University of Chicago, and then became a professor at the California Institute of Technology. He won the 1969 Nobel Prize in Physics for his contributions to the classification of elementary particles and their interactions. He founded the Santa Fe Institute for the study of complex systems.

Key discoveries

Introduction of quarks in 1964 as fundamental constituents of hadrons
which explained the 'particle zoo'
classification of particles via the eightfold way based on the SU(3) group
hypothesis of the absence of free color states (confinement)
contribution to the theory of weak interactions
strangeness and other quantum numbers
also worked on chiral symmetry.

💡 The name 'quark' comes from Joyce's novel 'Finnegans Wake' ('Three quarks for Muster Mark!'). Gell-Mann was also known as a polymath, with interests in linguistics and ornithology.

Quote: "I would like to think that the particle we call the 'quark' is the last step on the path to understanding matter, but who knows what will come next?"
