  1. Murray Gell-Mann By: Veronica Draayers and Brin Gibson

  2. 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

  3. 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)

  4. 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

  5. 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
