The world's most entertaining and useless self-help guide, from the brilliant mind behind the wildly popular webcomic xkcd and the #1 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 bad 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.

Bestselling author and cartoonist Randall Munroe explains how to predict the weather by analyzing the pixels of your Facebook photos. He teaches you how to tell if you're a baby boomer or a 90's kid by measuring the radioactivity of your teeth. He offers tips for taking a selfie with a telescope, crossing a river by boiling it, and getting to your appointments on time by destroying the Moon. And if you want to get rid of the book once you're done with it, he walks you through your options for proper disposal, including dissolving it in the ocean, converting it to a vapor, using tectonic plates to subduct it into the Earth's mantle, or launching it into the Sun.

By exploring the most complicated ways to do simple tasks, Munroe doesn't just make things difficult for himself and his readers. As he did so brilliantly in What If?, Munroe invites us to explore the most absurd reaches of the possible. Full of clever infographics and amusing illustrations, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.

Randall Munroe is the author of the popular webcomic xkcd and the science question-and-answer blog What If. Randall was born in Easton, Pennsylvania and grew up outside Richmond, Virginia. After studying physics at Christopher Newport University, he got a job building robots at NASA Langley Research Center. In 2006, he left NASA to draw comics on the internet full-time, supporting himself through the sale of xkcd t-shirts, prints, posters, and books. He likes candlelight dinners and long walks on the beach. Very long walks. Lots of people say they like long walks on the beach, but then they get out on the beach and after just an hour or two, they say they're getting tired. Bring a tent. He lives in Massachusetts.
