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.”

Freeman Dyson Interview

December 27th, 2009 by Lewis Frumkes

Freeman Dyson who has long been a legend at The Institute for Advanced Study at Princeton is a theoretical physicist and mathematician of the first order, a futurist, and a nuclear engineer. British by birth, Dyson studied with Hans Bethe at Cornell before moving to the Institute for Advanced Study.  He is probably best known for demonstrating in 1949 the equivalence of the formulations of quantum electrodynamics that existed at the time— Feynman’s diagrammatic path integral formulation and the operator method developed by Julian Schwinger and Sin-Itiro Tomonaga for which Schwinger, Feynman, and Tomonaga shared the Nobel Prize. Dyson also did seminal work in topology, analysis, number theory, random matrices and other abstruse topics in mathematics.  On first meeting him Dyson can seem a tad eccentric, subversive, perfectionistic and cantankerous. . . but ultimately with his impish little smile he comes across as quite charming. When I asked him of all the scientists with whom he worked whom he thought possessed true genius, he unhesitatingly answered. . . Richard Feynman.
