Levy, a writer and journalist specializing in history and science, uses 100 analogies to illustrate scientific concepts and principles in a way that general readers can understand. They relate to physics, chemistry, biology, astronomy, earth science, the human body, and technology, and illustrate concepts such as how large a nucleus would be in an atom using the idea of a bee in a cathedral, the history of the earth described as one day, and DNA and RNA as a zipper. Each idea is presented with illustrations in a two-page spread. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
