Host: Chris Mooney

It's the beginning of a new year here at Point of Inquiry, and we've got a pretty good guest to kick it off.

He needs no introduction. He's Brian Greene—celebrity physicist, bestselling author, television star and all around science communication maestro.

Officially: Greene is co-founder and director of Columbia University's Institute for Strings, Cosmology, and Astroparticle Physics, author of the bestselling books The Elegant Universe and The Fabric of the Cosmos, and co-founder of the World Science Festival.

We caught up with Greene to discuss the recently aired four part NOVA special based on The Fabric of the Cosmos, as well as, well, sciency things in general.
