Fermilab Colloquium Today
James D. Bjorken
Former Fermilab Associate Director for Physics, James D. Bjorken, will present today's colloquium entitled, "The Classification of Universes," at 4:00 p.m. in One West. Bjorken, who was at Fermilab during the 1980's, spent most of his career at SLAC, where he is now Professor Emeritus. He had a major impact on our current understanding of particle physics. Ten years before the November Revolution of 1974, the first experimental evidence for the charm quark, Bjorken and Glashow had suggested its existence and named it "charm". In the 1990's Bjorken was a cospokesman for the Tevatron experiment T864. Since (virtual) retirement, he has become involved in cosmology, and will present some of his ideas about the Universe at today's talk.
