Murray Gell-Mann is the Robert Andrews Millikan Professor of Theoretical Physics Emeritus at Caltech and widely regarded as one of the smartest men on the planet. Suffice that he speaks 15 languages, graduated from Yale University at the age of 18 and in 1969 won the Nobel Prize in physics for his work on elementary particles. Essentially he formulated the quark model of hadronic resonances, and identified the SU(3) flavor symmetry of the light quarks, extending isospin to include strangeness, which he also discovered. He also collaborated with Richard Feynman to discover the V-A theory of chiral neutrinos. Join us as we discuss basic concepts of cosmology, GUT theory, and Murray’s book “The Jaguar and The Quark.”
