Nuclear Slide Rules (via Dinosaurs and Robots)
As a convenience to those interested in the effects of nuclear weapons, this circular computer was designed to make data easily available on various weapon effects - some as functions of both yield and range and others on yield alone . . . The weapons data incorporated in this computer were taken from the very informative and useful text, The Effects of Nuclear Weapons, edited by Samuel Glasstone for the Armed Forces Special Weapons Project of the Department of Defense.
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.
