“String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation.”

American physicist, professor, and science festival chairman

Brian Greene is an American physicist and professor of physics and mathematics at Columbia University. He is known for his work on string theory and for co-founding the World Science Festival in 2008. He directs Columbia’s Center for Theoretical Physics and serves as chairman of the festival. Greene also co-discovered mirror symmetry, a relation between two different Calabi-Yau manifolds, and described the flop transition and the conifold transition, showing how topology can change smoothly in string theory.
