What If? Serious Scientific Answers to Absurd Hypothetical Questions

This book is awesome. Randall Munroe does a really good job with explaining science to everyone (everyone who knows xkcd already knows this).

The topics are short but informative. You always get way more information than you thought, and with its on point humor it's just fun to read.

I really learned some new stuff, and even though most of the topics are really crazy, I already could shine with some knowledge or facts around my friends.

I really can recommend this to everyone. Fun!
