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.)
Look, I answer questions for a living, too, and Randall is really, really good at this. He finds weird little scientific ways to answer the questions, but it’s his extrapolations that kill me. I laughed a lot reading this book. Even better: I learned stuff reading this book. And you will too.
