Geology is a branch of science that I know very little about. I got this illustrated introduction from the Folio Society (possibly for free). This is the guy who wrote "Trilobites!", one of my favorite book titles. He uses various places around the world to exemplify a particular geological principle and includes a lot of the history of the development of the science. I especially enjoyed his trip into the grand canyon on a burro. There is an awful lot of squeezing and thrusting here, and I occasionally passed out while reading this.
