In the interests of science, the presenter from the BBC's "How We Shook the World" hits a droplet of nitro with a hammer, over and over again, in slow motion. I am enscienced!
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.
