How Machines Work

The judges said: “This book isn’t just dry pages about what engineering is. It’s a very exciting story about a sloth that has to get somewhere and in order to get to where he’s going; he has to build levers, he has to build bridges. Each of the pages is about how he designs a solution to a problem - just what an engineer must do.”
