Hedge fund billionaire and mathematician Dr. Jim Simons was in attendance on Tuesday for a pre-grand-opening tour of the Simons Center for Geometry and Physics. The center, a 40,000-square-foot building certified with a gold LEED label from the U.S. Green Building Council, was built with a $60 million donation Simons made in 2008, which remains the largest donation to a single SUNY school.
