Summary

The fourth book in the Science of Discworld series, and this time around dealing with the really big questions, Terry Pratchett’s brilliant new Discworld story Judgement Day is annotated with very big footnotes (the interleaving chapters) by mathematician Ian Stewart and biologist Jack Cohen, to bring you a mind-mangling combination of fiction, cutting-edge science and philosophy.

Marjorie Daw is a librarian, and takes her job – and indeed the truth of words – very seriously. She doesn’t know it, but her world and ours – Roundworld – is in big trouble. On Discworld, a colossal row is brewing…The Wizards of Unseen University feel responsible for Roundworld (as one would for a pet gerbil). After all, they brought it into existence by bungling an experiment in Quantum ThaumoDynamics. But legal action is being brought against them by Omnians, who say that the Wizards’ god-like actions make a mockery of their noble religion.

As the finest legal brains in Discworld (a zombie and a priest) gird their loins to do battle – and when the Great Big Thing in the High Energy Magic Laboratory is switched on – Marjorie Daw finds herself thrown across the multiverse and right in the middle of the whole explosive affair.

As God, the Universe and, frankly, Everything Else is investigated by the trio, you can expect world-bearing elephants, quantum gravity in the Escher-verse, evolutionary design, eternal inflation, dark matter, disbelief systems – and an in-depth study of how to invent a better mousetrap.

Proper science told engagingly and well.<br />

Bang up to date and with plenty of modern parables. Buy it for your friends who had no science education.

More of the strange blend, of fact, and disk world

If you could sum up The Science of Discworld IV in three words, what would they be?

Magic Meets Science

What other book might you compare The Science of Discworld IV to, and why?

More from the ongoing sieres, of disk world science. A parallel to the disk world books, including a lot of actual information on (our) round world science. It gives the diskworld fan an insight into the mind of the writer, and some interesting facts.

Very interesting bit of info, too much to take in one go

Discovering what roundworld is and how it formed

Did you have an emotional reaction to this book? Did it make you laugh or cry?

A very funny piece, chooses its comedy wisely,

Any additional comments?

Very good read, is a little too based in reality with reference to discworld, I expected it to bathe other way round

A classic theology of atheism. Pick what suits

Methodology that is encased in the exact thing it portrays to abhor. Decides all religious leanings are the same and is, as pompous as could be.

Loved the 'make-believe' Discworld bits, but the arrogance of perceived intellect, from the 'factual' interludes was embarrassing.

'can't explain the basics' Dawkins, would be proud.
