Terry Pratchett - The Science of Discworld IV: Judgement Day: Its Wizards Vs Priets in a Battle for the Future of Roundworld

Order in Court!
On Discworld an almighty row is brewing

The Omnians want control of Roundworld its very existence makes a mockery of their religion. The wizards of Unseen University, however, are extremely reluctant to part with it. After all, they created it!

Enter Roundworld librarian, Marjorie Daw (accidentally, through L-space). Perhaps, with her Jimmy Choos and her enquiring and logical mind, she can help? Especially as shes the sort of librarian who thinks that the Bible should be filed under Science Fiction and Fantasy.

Lord Vetinari presides over the tribunal. People on both sides are getting extremely angry. There are some very big questions being asked and someones got some explaining to do

The fourth in the Science of Discworld series, JUDGEMENT DAY sees Terry Pratchett, Professor Ian Stewart and Doctor Jack Cohen create a mind-mangling mix of fiction, cutting-edge science and philosophy in an attempt to answer the REALLY big questions this time taking on God, the Universe and, frankly, Everything Else.

Proceed with caution, you may never look at your universe(s) in the same way again.

Sir Terry Pratchett is the acclaimed creator of the global bestselling Discworld series; the first Discworld book, The Colour of Magic, was published in 1983. In all, he is the author of fifty bestselling books. His novels have been widely adapted for stage and screen, and he is the winner of multiple prizes, including the Carnegie Medal, as well as being awarded a knighthood for services to literature. Worldwide sales of his books now stand at 75 million.

Professor Ian Stewart is the author of many popular science books and appears frequently on radio and television. He is an Emeritus Professor of Mathematics at the University of Warwick. He was awarded the Michael Faraday Medal for furthering the public understanding of science, and in 2001 became a Fellow of the Royal Society.

Dr Jack Cohen is an internationally renowned reproductive biologist. He has retired to a small thatched cottage in Dorset. He writes, ponders, and plays with microscopes in a rather grand garden shed. He also throws boomerangs, but doesnt catch them as often as he used to. In addition, he still enjoyes lecturing and continues to have a passion for the public understanding of science.

CONTENTS

There is a sensible way to make a world.

It should be flat, so that no one falls off accidentally unless they get too near the edge, in which case its their own fault.

It should be circular, so that it can revolve sedately to create the slow progression of the seasons.

It should have strong supports, so that it doesnt fall down.

The supports should rest on firm foundations.

To avoid an infinite regression, the foundations should do what foundations are supposed to do, and stay up of their own accord.

It should have a sun, to provide light. This sun should be small and not too hot, to save energy, and it should revolve around the disc to separate day from night.

The world should be populated by people, since there is no point in making it if no one is going to live there.
