What If? 10th Anniversary Edition: Serious Scientific Answers to Absurd Hypothetical Questions Munroe Randall (2024)

Celebrating ten years of the million-selling pop science classic, this special edition presents hilarious and informative answers to absurd hypothetical questions from Randall Munroe, creator of xkcd.com. How fast can you hit a speed bump and survive, when might the sun have set on the British Empire, and how many people would a rampaging T. Rex need to eat each day? To find answers, Munroe runs computer simulations, studies declassified military research, solves differential equations and consults nuclear reactor operators. His clear and funny explanations are accompanied by comics, which often predict the complete annihilation of humankind or at least a very large explosion. This anniversary edition includes revised content, new two-colour annotations and illustrations.
