‘What If?: Serious Scientific Answers to Absurd Hypothetical Questions’ by Randall Munroe of xkcd

What If? Book by xkcd

What If?: Serious Scientific Answers to Absurd Hypothetical Questions (see previously) is a new book by Randall Munroe (creator of xkcd) that compiles the best answers from his blog of hypothetical science questions, What if? It is now available for purchase on Amazon.

As I’ve sifted through the letters submitted to What If every week, I’ve occasionally set aside particularly neat questions that I wanted to spend a little more time on. This book features my answers to those questions, along with revised and updated versions of some of my favorite articles from the site. (I’m also including my personal list of the weirdest questions people have submitted.)
