Randall Munroe is a genius. That's not stating the obvious, as much as it seems so, even if you are vaguely familiar with his work. Coming from the creator of the webcomic xkcd' and former NASA roboticist, it is very clear that this is a smart and incredibly scientific mind at work. His comics reflect that, often about complicated topics simplified into stick figures and pop culture references. His genius, though, goes beyond the scientific, into something some might say is even harder. Comedy. Hilariously funny, Munroe writes with all the seriousness of a scholar, and the irreverence of a child at play. His book, What If?, is a culmination of his incomprehensible amounts of knowledge, his endless wit, and his ability to draw stick figures in hats. He had fans of his webcomic submit ridiculous, science and math based questions and he endeavored to answer them as factually and scientifically as possible, which resulted in some of the most laugh out loud funny reading I've had in ages. It is an easy book to pick up and look through, despite the seemingly complicated questions, but I recommend sitting down with it and reading it cover to cover.
The creator of the incredibly popular webcomic xkcd presents his heavily researched answers to his fans' oddest questions, including ?What if I took a swim in a spent-nuclear-fuel pool?? and ?Could you build a jetpack using downward-firing machine guns?? 100,000 first printing.
