Randall Munroe is the author of the #1 New York Times bestsellers What If? and Thing Explainer, the science question-and-answer blog What If, and the popular webcomic xkcd. A former NASA roboticist, he left the agency in 2006 to draw comics on the internet full-time. His new book, How To: Absurd Scientific Advice for Common Real-World Problems (available in September) is billed as "the world's most entertaining and useless self-help guide."
