Randall Munroe's new book "How To" is the world's most interesting and useless self-help guide, from the brilliant mind behind the wildly popular webcomic "xkcd" and the New York Times bestsellers "What If?" and "Thing Explainer." For any task you might want to do, there’s a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It’s full of highly impractical advice for everything from landing a plane to digging a hole. By exploring the most complicated ways to do simple tasks, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.
