Murray Gell-MannOrigin: United States of America By: Josie Boltjes-Johnson
Murray Gell-MannBorn September 15th, 1929 in New York City.Got his B.Sc. At Yale University in 1949.In 1952, got his Ph.D. Ph.D. was from Massachusetts Institute of Technology.Yale Massachusetts Institute of Tech.
PhysicsFormulated the quark model of hadronic resonances.Identified the SU(3) flavor symmetry of light quarks.Created current algebra in 1960.Responsible for see-saw theory of neutrino masses. Quark model
PhysicsDiscovered the sigma model of pions.Kept string theory going throughout the 1970s.With help of others they discovered, Quantum Chromodynamics.That was in 1984.
The Quark ModelElementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons. There are six types of quarks -up -down -charm -strange -top - bottom
The Quark ModelUp and Down has lowest masses.Charm, strange, top, and bottom only produced in..High energy collisions.(Involving cosmic rays and particle accelerators.)
The Quark ModelQuarks have carious intrinsic properties. -Electric charge -Color charge -Spin
The Quark ModelClassified as the Eightfold Way.Gell-Mann and George Zweig proposed it in 1964.It wasnt until 1977 it was official.Named it after the sound made by ducks.
Murray Gell-MannMarried in 1992, to Marcia Southwick.After she died he married again to J.Margaret Dow.Had 3 children.1 girl and 2 boys.
