# Brian Greene

**Brian Greene**is a physicist who is considered one of the world's foremost string theorists. As of 2003, he is a professor at Columbia University.

He is the author of , a popularization of superstring and M-theory, and winner of *The Aventis Prizes for Science Books* in 2000. The book talks about and opens an argument on how Calabi-Yau manifolds, as the multi-dimensional (11D, 16D, 26D) *points*, comprise our space-time. *The Elegant Universe* was later made into a PBS television special with Greene as the narrator. His second book, *The Fabric of the Cosmos* is about space, time, and the nature of the universe.

## Important contributions to physics

- Brian Greene is one of the fathers of mirror symmetry relating two different Calabi-Yau manifolds (concretely, relating the conifold to one of its orbifolds)
- He (and David Morrison and Paul Aspinwall) also understood the flop transition, a mild form of topology change
- Together with David Morrison and Andrew Strominger, they showed that topology in string theory can change at the conifold point
- He currently studies stringy cosmology, especially the imprints of trans-Planckian physics on the cosmic microwave background, and brane-gas cosmologies that could explain why the space around us has three large dimensions
