Stanford University Professor and Nobel Laureate in physics Douglas Osheroff will present “How Advances in Science Are Made” at the Physics and Astronomy Colloquium 4 p.m. Thursday, Feb. 25, in Mendocino Hall, Room 1015.

Osheroff’s research efforts are centered on studies of quantum fluids, solids and gasses at ultra-low temperatures. He received the Nobel Prize for Physics in 1996.

He will also speak at 2 p.m. Thursday, in Sequoia Hall, Room 316 on Nobel prize-winning physicist Richard Feynman who helped develop the atomic bomb and was a member of the government commission investigating the Challenger space shuttle disaster. At the time of his death in 1988, Feynman was one of the most recognized scientists in the world, and in 2005, the U.S. Post Office issued a stamp honoring him.

Both events are free and open to the public.
