This is just a fun book to read if you have any interest in science and the world around us.Bryson claims he got the idea for this book while flying over an ocean and thinking, "I should know know more about the world and what makes it tick" or something to that end. However he got the idea, the result is a solid book. Short History breaks down into the scientific history of the Universe, the Earth, and Humans. Almost every page teaches you something fascinating and there is an underlying message about how the truth, when new, will be fought vigorously almost without fail.The whole thing is written in a witty style that keeps you turning the pages.
