The Science of Discworld II: The Globe is a 2002 book written by the novelist Terry Pratchett and the popular science writers Ian Stewart and Jack Cohen. It is a sequel to The Science of Discworld, and is followed by The Science of Discworld III: Darwin's Watch.
The book alternates between a typically absurd Discworld story and serious scientific exposition.
Where the first book centred on the origins of the universe, earth and the beginnings of life, the second part follows the modern history of Earth. The central theme in the book is that in order for humans to understand anything it must be encapsulated in a story. In the fictional part of the book this is symbolized by the fictional element 'narrativium'. The science section suggests that, rather than Homo sapiens (Wise Man), we might be better described as Pan narrans (Storytelling Chimpanzee).
