Readers of xkcd—Randall Munroe’s webcomic about math, language, love, and other nerdy things—asked, and Munroe answered, with illustration—and real science. Whether you’re curious about what would happen if you took a swim in a spent nuclear pool, or want to know if you could build a jetpack using downward-facing machine guns, or wonder what would happen if someone’s DNA vanished, there’s only one book that will give you serious (and entertaining!) scientific answers to absurd hypothetical questions.
