From the creator of the wildly popular xkcd.com, hilarious and informative answers to important questions you probably never thought to ask.

Fans of Randall Munroe ask him a lot of strange questions: How fast can you hit a speed bump, driving, and live? When (if ever) did the sun go down on the British Empire? When will Facebook contain more profiles of dead people than living? How many humans would a T Rex rampaging through New York need to eat a day? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations and consults nuclear reactor operators. His responses are masterpieces of clarity and hilarity, complemented by comics. (They often predict the complete annihilation of humankind, or at least a really big explosion.)

In celebration of 10 years of unusual insight, Randall Munroe has revised his classic blockbuster to ask what if? x 10. Featuring brand-new 2-colour annotations and illustrations, this special anniversary edition will leave you feeling much smarter, whether you have a Nobel Prize or not.
