Murray Gell-Mann

  • Born 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.

 Massachusetts Institute of Tech.

Yale 


Physics

Physics

  • Formulated 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


Physics1

Physics

  • Discovered the sigma model of pions.

  • Kept string theory going throughout the 1970’s.

  • With help of others they discovered, Quantum Chromodynamics.

  • That was in 1984.

The Quark Model

  • Elementary 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 model

The Quark Model

  • Up and Down has lowest masses.

  • Charm, strange, top, and bottom only produced in..

  • High energy collisions.

  • (Involving cosmic rays and particle accelerators.)


The quark model1

The Quark Model

  • Quarks have carious intrinsic properties.

    -Electric charge

    -Color charge

    -Spin

    -Mass


The quark model2

The Quark Model

  • Classified as the Eightfold Way.

  • Gell-Mann and George Zweig proposed it in 1964.

  • It wasn’t until 1977 it was official.

  • Named it after the sound made by ducks.

Murray Gell-Mann

  • Married in 1992, to Marcia Southwick.

  • After she died he married again to J.Margaret Dow.

  • Had 3 children.

  • 1 girl and 2 boys.

  • Boys: Nicholas Webster, (step son) Nicholas Southwick Lewis.

  • Total of 30 awards/honors in lifetime.

  • Knew 13 languages and spoke fluently.
