What If?: Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe
Munroe, a NASA roboticist in his past career, is the creator of the webcomic xkcd which has a blog portion called What If. In the What If blog Munroe answers strange questions with real science broken down into layman’s terms and illustrated with stick figures. For this book he collected some of his favorite, most popular, and some new questions and answers. If you have any interest in physics, math, basically anything to do with science, and you have an odd sense of humor (like me apparently), you should probably give this one a chance. I especially enjoyed his explanation of human genetics using D&D character stats and the way he explained not only the destructive end of the Richter scale, but it’s gentler side as well.
If you were that kid that always asked why? and how? this is the book that will finally give you the answers to the hard questions – like how many people would need to shoot laser pointers at the moon to make it change color and what would happen if you swam in a spent-nuclear-fuel pool? Trust me, you want to know.
