Brian Greene holds two professorships at Columbia University, in physics and in mathematics, and directs its Center for Theoretical Physics. His research sits in string theory: he co-discovered mirror symmetry between Calabi-Yau manifolds and described the flop and conifold transitions, results which showed that the shape of space itself can change smoothly. He was born in New York in 1963.
He is far better known, however, as the man who made that material readable. The Elegant Universe, The Fabric of the Cosmos, The Hidden Reality and Until the End of Time were all New York Times bestsellers, and two of them became award winning television series. Greene co-founded the World Science Festival in 2008 and still chairs it.
What sets him apart from other popularisers is that he does not simplify by omission. He builds an analogy, tests it, admits where it breaks, and then hands you the better one. It is teaching rather than showmanship.
