Brian Greene

American theoretical physicist and string theorist. 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.

Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
