Particle Zoo sells this adorable cuddly Higgs Boson for your kid's crib or your cubicle. No way to tell from the photo if it's very massy or just moving very fast in another spatial dimension. Higgs Boson (via Wonderland)
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.
