The Kimberley Academy in Montclair, New Jersey hosted a fascinating, one-hour chat between Neil DeGrasse Tyson -- Hayden Planetarium director, TV science host, and all-round good guy -- with Stephen Colbert in a rare, out-of-character appearance.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
