The Science of Discworld II
"In The Science of Discworld, the wizards of Unseen University unwittingly created Earth (aka Roundworld) and our universe. At the time, they were so concerned with the rules of this new universe that they overlooked its inhabitants completely. Now, they have finally noticed humanity. And humanity has company: Elves, who want very much to take over human society. In this second installment in the Science of Discworld miniseries, Terry Pratchett and acclaimed science writers Jack Cohen and Ian Stewart weave the history of the human mind, culture, language, art and science into a story in which the wizards compete with the elves for control of Roundworld and grapple with the nature of Good and Evil. All the while, the authors explore history as it is rewritten over and over, presenting a fascinating and brilliantly original view of the world we live in"--
