One of the great physicists of our times Murray Gell-Mann has died at 89. He introduced the quark model for hadrons, ‘Strangeness’ in the decay of certain particles, arrived at SU(3) symmetry, ‘Eightfold Way’ classification scheme of hadrons that led to the discovery of the Omega minus particle and a whole host of other contributions. He entered Yale College at the age of 15; That just about says it all. Fascinating to listen to and is often entertainingly blunt and honest. Highly recommended to check out vidoes of him on Youtube:
