Brian Greene has worked on mirror symmetry and the flop transition, and he deals with Calabi-Yau manifolds, relating the conifold to one of its orbifolds.
If
you aren't sure what any of that means, that makes two of us.
Actually, given the fact that my spell check program doesn't know
many of those words, I suspect that makes billions and billions of us
that don't know what that means!Okay, let's get down to things we DO get: Brian Greene, born on this day in 1963, is a theoretical physicist and string theorist. He is also a professor at Columbia University, an author of books for the general public, chairman of the World Science Festival, and occasional TV personality on The Big Bang Theory and PBS specials.
String
theory is a possible explanation for why there is gravity, along with
other deep questions of physics and cosmology. String theorists hope their theory can join the theories of Relativity and of Quantum Mechanics, the physics of the very large and the physics of the very small. Basically, it is a
Theory of Everything.
(I
think!)
Actually,
several sources explain that string theory is a theory of quantum gravity, which is the field of physics that is trying to describe
the force of gravity according to the principles of quantum
mechanics.

is a super-short explanation of string theory...and here is today's birthday honoree, Brian Greene himself, talking about string theory.
