Four uniquely entertaining non-fiction books from the perspective of the scholars of Discworld - essential for all Terry Pratchett fans. As a result of a failed experiment, the wizards of the Unseen University suddenly possess a miniature universe: the earthly round world. Under the guidance of the wise wizards, we follow the history of our universe from the Big Bang to the Internet and beyond. In "The Science of Discworld," Terry Pratchett and the scientists Ian Stewart and Jack Cohen not only tell new stories from the flattest planet in the known universe but also present us with the latest insights from modern physics, astronomy, and biology in an equally exciting and humorous way. With these volumes, we gain a better understanding of our world - and perhaps of ourselves as well.
