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 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. 

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 powering your house by destroying the fabric of space-time. 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 listeners. As he did so brilliantly in What If?, Munroe invites us to explore the most absurd reaches of the possible. How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.
“The creator of the popular, extremely excellent and not a little nerdy webcomic ‘xkcd’ cleverly illustrates a guide of complicated solutions to simple tasks, thinking up Rube Goldbergian solutions to tasks as common as digging a hole.” USA Today

“[How To] tackles problems from the mundane—such as how to move to a new house—to those that may trouble a mad scientist building her first lava moat. The solutions are often hilariously, and purposefully, absurd. Embedded in these solutions, however, is solid scientific, engineering, and experimental understanding . . . [for] anyone who appreciates science-based, but Rube Goldberg–esque, solutions to life’s problems.” Science Magazine

“How To is a pure delight, a salty-sweet mixture of hard science and bonkers whimsy.” BoingBoing

“A brilliant provocation of a book: clamber in for a wild ride.”Nature

“A witty, educational examination of ‘unusual approaches to common tasks’ . . . generously laced with dry humor . . . Munroe’s comic stick-figure art is an added bonus. . . .  Apart from generating laughter, the book also manages to achieve his serious objective: to get his audience thinking.” Publishers Weekly, starred review

“An enjoyable treat for fans of logic puzzles, brain hacking, kaizen, mad science, and other forms of mental stimulation.” Kirkus Reviews

“Munroe (creator of the webcomic xkcd; What If?; Thing Explainer) creates another fun series of questions and answers that explore forces, properties, and natural phenomena through pop-culture scenarios . . . With illustrated formulas that humorously explain the science behind Munroe’s conjectures, this book is sure to entertain and educate thinkers from high school on up.” Library Journal

How To is a gleefully nerdy hypothetical instruction book for armchair scientists of all ages.” Booklist
