How to

How to: Absurd Scientific Advice for Common Real-World Problems
by Randall Munroe
Riverhead Books, 2019. 307 pages. Nonfiction

There's more than one way to solve every problem. There's a right way, a wrong way, and a way that is so tremendously wrong that no one would ever attempt it. This book is guide to that third approach to many of life's basic tasks. The creator of the popular website xkcd.com and former NASA roboticist Randall Munroe provides outlandishly absurd solutions (grounded in real-life science and technology) to everyday obstacles; learn how to build a lava moat around your house (your HOA may not approve), how to cross a river by boiling it, and how to get to your appointments on time by destroying the Moon.

Like Munroe's previous book "What If?", "How to" invites readers to explore the furthest reaches of what is physically possible. The math can sometimes get a bit dense, but Munroe does a good job keeping the tone conversational and accessible for the nonexpert; for example, consider this quote:

Without shielding, spacecraft break up in the atmosphere. When large spacecraft enter the atmosphere without a heat shield, between 10 percent and 40 percent of their mass usually makes it to the surface, and the rest melts or evaporates. This is why heat shields are so popular.

Clever infographics and illustrations help the reader visualize the preposterous ideas that Munroe suggests, showcasing the science and technology that underlie our everyday routines; bear in mind that you'll miss out on these if you choose the audiobook over physical or eBook formats. Perfect for those familiar with the physical sciences and for those familiar with life on Earth (or Mars).
