"This is a hilarious yet edifying talk on Sex given by Prof. Sapolsky to his Bio l50/250 Human Behavioral Biology class at Stanford in Spring 2002" -- regular readers of this blog will remember Sapolsky as the incredibly fascinating, funny and engaging scientist whose Stanford lectures on stress are some of the most interesting biology presentations I've ever heard.
He's absolutely scintillating on the subject of primate sexuality: funny, informative, and filled with aha moments that'll have you rethinking your relationship to your naughty parts.
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.
