My contribution is this fantastic presentation by physicist Lisa Randall at the Origins conference in Tallahassee Florida, broadcast last Friday as part of NPR's Science Friday show. Randall is the author of Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions, a popular science book that addresses fundamental questions about the nature of the universe. On this show, Randall explains what an expanding universe is expanding into, the relationship of gravity, magnetism and hidden time-space dimensions, and other mind-benders about the origin of the universe (she also talks a little about the role of women in science).
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.
