"From brain cells to black holes" -- Cover.

Discover an all-in-one encyclopedia that takes you on an explanatory tour of the world from your own body to outer space. Have you ever wondered how an email gets to someone on the other side of the world in just a few seconds or why it's a bad idea to stand under a tree during a thunderstorm? Discover the answers to all these questions and more with this mind-boggling books of facts. Each page of this mind-blowingly detailed and ambitious encyclopedia will guide you through the natural world and the technology that surrounds you. Giant, page-filling illustrations take objects apart--or take the roofs and walls off buildings--to show you how they work, explaining both basic principles (such as photosynthesis) as well as broader concepts (like how all the living things in a rainforest interact).
