Murray Gell-Mann

By: Veronica Draayers and Brin Gibson

personal story
Personal Story
  • Born September 15, 1929 in lower Manhattan
  • Child prodigy
  • Entered Yale at the age of 15 as a member of Jonathan Edwards college
  • American physicist and linguist
  • Received Noble Prize in physics in 1969
  • He is currently the Robert Andrews Milikan Professor of Theoretical Physics Emeritus at Caltech
idea of the atom
Idea of the atom
  • He developed the quark diagram
  • He found that all of the particles in the nuclei, such as the protons and the neutrons are made up of quarks
  • Protons and neutrons are called hadrons
  • Protons are made up of three quarks
  • Quarks are the fundamental building blocks of protons and neutrons

Quark Model (way to classify hadrons in their valence quarks)

experiments area of study
Experiments / Area of Study
  • Quantum Mechanics
  • By the 1960’s nearly 100 different particles had been discovered in the nucleus of the atom.
  • Gell-Mann classified them using their electrical charge and “strangeness” in octets or “the eightfold way”.
  • noticed that there was an empty spot and estimated the charge and “strangeness” number to develop quarks.
  • Proton smashing
major scientific contribution
Major Scientific Contribution
  • He helped come up with the accepted theory of quantum chromodynamics (fundamental force describing the interactions between quarks and gluons)
  • He is also known for the see-saw theory of neutrino masses (helps describe the masses of neutrinos relative to quarks)
  • He helped keep the idea of string theory alive when the concept was unpopular
