Learn moreA special tenth anniversary edition of the million-copy bestseller What If? from the creator of the wildly popular webcomic xkcd—revised and annotated with answers to important questions you never thought to ask.
Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away?
In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, complemented by his signature xkcd comics. (They often predict the complete annihilation of humankind, or at least a really big explosion.)
In celebration of ten years of unusual insight, Randall Munroe has revised his classic blockbuster to ask what if? times ten. The result is ten times the adventure of scientific inquiry. This special anniversary edition is far more than a book for geeks, What If? explains the laws of science in operation in a way that every intelligent listener will enjoy and feel much smarter for having listened to.
Randall Munroe is the author of the popular webcomic xkcd and the science question-and-answer blog What If? Randall was born in Easton, Pennsylvania, and grew up outside Richmond. After graduating with a degree in physics from Christopher Newport University in Newport News, Virginia, he got a job building robots at NASA’s Langley Research Center. In 2006 he left NASA to draw comics on the Internet full time, supporting himself through the sale of xkcd t-shirts, prints, posters, and books. He likes candlelight dinners and long walks on the beach—very long walks. Lots of people say they like long walks on the beach, but then they get out on the beach, and after just an hour or two, they say they’re getting tired. Bring a tent. He lives in Massachusetts.

Reviews
“What If? maintains a delightfully free-wheeling tone throughout, especially when complicated calculations lead to whimsical results…Despite all the hard facts and gigantic numbers, it never feels like a textbook—and you don’t have to be a rocket scientist to enjoy it.”
“Consistently fascinating and entertaining…Munroe leavens the hard science with whimsical touches…An illuminating handbook of methods of reasoning.”
