"How to Invent Everything is such a cool book. It's essential reading for anyone who needs to duplicate an industrial civilization quickly." --Randall Munroe, xkcd creator and New York Times-bestselling author of What If?

The only book you need if you're going back in time

What would you do if a time machine hurled you thousands of years into the past. . . and then broke? How would you survive? Could you improve on humanity's original timeline? And how hard would it be to domesticate a giant wombat?

With this book as your guide, you'll survive--and thrive--in any period in Earth's history. Bestselling author and time-travel enthusiast Ryan North shows you how to invent all the modern conveniences we take for granted--from first principles. This illustrated manual contains all the science, engineering, art, philosophy, facts, and figures required for even the most clueless time traveler to build a civilization from the ground up. Deeply researched, irreverent, and significantly more fun than being eaten by a saber-toothed tiger, How to Invent Everything will make you smarter, more competent, and completely prepared to become the most important and influential person ever. You're about to make history. . . better.
