For people who have always wondered: What if? Now, all (or at least a few) of your questions have been answered! What if everyone in the world jumped at the same moment? How many hand-held laser would it take to destroy the moon? If you only have one soul-mate, what is the probability you two would meet? Bizarre and oddly satisfying read by the author of web comic xkcd. Great gift for a math major! — Leah Moore
Compiling some of the best answers from online as well as an assortment of fresh, print-only material, What If? has a lot to teach, hidden under its whimsical writing and simple - yet surprisingly helpful - illustrations.— Andrew Bugenis
From the creator of the wildly popular webcomic xkcd comes this hilarious and informative book of answers to important questions you probably never thought to ask.
Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?
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 signature xkcd comics. They often predict the complete annihilation of humankind, or at least a really big explosion.
The book features new and never-before-answered questions, along with updated and expanded versions of the most popular answers from the xkcd website. What If? will be required reading for xkcd fans and anyone who loves to ponder the hypothetical.
