Have you ever tried to learn more about some incredible thing, only to be frustrated by incomprehensible jargon? Randall Munroe is here to help. In he uses line drawings and only the thousand (or, rather, “ten hundred”) most common words to provide simple explanations for some of the most interesting stuff there is, including: How do these things work? Where do they come from? What would life be like without them? And what would happen if we opened them up, heated them up, cooled them down, pointed them in a different direction, or pressed this button? In Munroe gives us the answers to these questions and so many more. Funny, interesting, and always understandable, this book is for anyone—age 5 to 105—who has ever wondered how things work, and why.
