[PAR] [TLE] Brian Greene [SEP] Brian Randolph Greene (born February 9, 1963) is an American theoretical physicist, mathematician, and string theorist.  He has been a professor at Columbia University since 1996 and chairman of the World Science Festival since co-founding it in 2008.  Greene has worked on mirror symmetry, relating two different Calabi–Yau manifolds (concretely, relating the conifold to one of its orbifolds).  He also described the flop transition, a mild form of topology change, showing that topology in string theory can change at the conifold point. [PAR] [TLE] Calabi-Yau (play) [SEP] Calabi-Yau is a 2001 play written by playwright Susanna Speier with songs and music by Stefan Weisman, based on physicist Brian Greene's national bestseller "The Elegant Universe".
