Brian Greene Quotes
Even when I wasn't doing much 'science for the public' stuff, I found that four or five hours of intense work in physics was all my brain could take on a given day.
Greene, Brian. Interview by Todd VanDerWerff. The A.V. Club, 2 Nov. 2011.
Brian Randolph Greene is an American theoretical physicist, mathematician, and string theorist. Greene was a physics professor at Cornell University from 1990-1995, and 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.
