What If? - Randall Munroe

From the creator of the wildly popular kcd.

What If answers important questions you probably never thought to ask.

Millions visit xkcd.com each week to read Randall Munroe’s iconic webcomic. Fans ask him a lot of strange questions.

• How fast can you hit a speed bump, driving, and live?
• What would happen if someone’s DNA vanished?
• How many humans would a T Rex rampaging through
  New York need to eat a day?

In pursuit of answers, he runs computer simulations, digs through declassified military research memos, consults with nuclear-reactor operators, times scenes from Star Wars with a stopwatch, calls his mother, and Googles some very freaky-looking animals. This book features the most popular questions from the blog, but many (51 per cent!) are new.

When Randall Munroe is your guide, science gets really weird really fast. Near-light-speed baseball pitches can level entire city blocks. A mole of moles can suffocate the planet in a blanket of meat. Yoda can use the Force to recharge his electric-model Smart Car. Munroe’s hilarious and compelling answers explain everything from the odds of meeting your soulmate to the many ways you could die while building a periodic table out of the actual elements.

Welcome to the strange world of What If.
