Fully revised and updated with two new chapters.
When a thaumic experiment goes adrift, the wizards of Unseen University find that they've accidentally created a new universe. Within it is a planet that they name Roundworld, an extraordinary place where neither magic nor common sense seems to stand a chance against logic.
The universe, of course, is our own. And Roundworld is Earth. As the wizards watch their accidental creation grow, we follow the story of our universe from the primal singularity of the Big Bang to the evolution of life on Earth and beyond.
This original Terry Pratchett story, interwoven with chapters from science writers Jack Cohen and Ian Stewart, offers a wonderful wizards-eye view of our universe. Once you've seen the world from a Discworld perspective, it will never seem the same again . . .
