Publisher's 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 by mathematician Ian Stewart and biologist Jack Cohen, to bring you a mind-mangling combination of fiction, cutting-edge science, and philosophy.

Marjorie Dawe 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 the 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' godlike 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 Dawe 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.

There is nothing wrong with being an Atheist

It is a nice book about belief and what it means for different kinds of people.

very entertaining and thought provoking.

Heard the four chapters of the science of Disc World. All very much worth listening.

Good but dense

The discWorld side story is fun and relevant as usual. The science is at times very dense but also very solid. Tougher to grasp and retain in audio.

Overall very good.

not the same Terry?

while Ian Stewart and Jack Cohen's parts feel brilliant and objective as usual, Terry Pratchett's does not. I've read every discworld book in order of publication over the last 2 months and am confident when I say he feels like his personality is that of a very different person then he did before his Alzheimers, and has perhaps started to resent religion.. he always seemed so understanding before........ I loved the other science of Discworld books enormously, but this one feels strangely aggressive.. it hurts to read his parts because it doesn't even sound like him anymore......

12 hours of lectures and only 1 hour of story

Very disappointed. So little of this is actual Discworld fiction. Wish I had known that. I'd really like my money back.

Not as good as the prior ones.

Science lectures just rehashed prior topics, didn't really give us anything new. It felt like there was less Discworld, too -- even the introduction of a new character felt more like a tease than a story. As much as I love this series, I would recommend just skipping this one.

Terrible and condescending.

Normally I live Sir Terry's stories. I knew Sir Terry's was an atheist, but I always thought he more respect for his readers who did believe. I hate giving this review but the story was insulting and disrespectful to Christians. Stephen Briggs was wonderful as always. The story and the science of Disc World by Ian Stewart and Michael Cohen was condescending and disrespectful. This book is not worth reading or listening to.
