Terry Pratchett - Ian Stewart - Jack Cohen - The Science of Discworld III - Darwin's Watch
Roundworld is in trouble again, and this time it looks fatal. Having created it in the first place, the wizards of Unseen University feel vaguely responsible for its safety. They know the creatures who lived there escaped the impending Big Freeze by inventing the space elevator - they even intervened to rid the planet of a plague of elves, who attempted to divert humanity onto a different time track. But now it's all gone wrong again - Victorian England has stagnated and the pace of progress has slowed right down. Unless something drastic is done, there won't be time for anyone to invent spaceflight and the human race will be just another layer in the bedrock. Why, though, did history come adrift? Was it Sir Arthur J Nightingale's dismal book about natural selection? Or was it Mr Charles Darwin, whose bestselling Theology of Species made it impossible to refute the divine design of living creatures? Either way, it's not easy task to change history back, as the wizards discover to their cost. He's got to write a different book. And who stopped him writing it in the first place? What went wrong? In Darwin's Watch, Terry Pratchett, Ian Stewart and Jack Cohen weave together a brand new fast-paced Discworld novelette with cutting-edge scientific commentary. The result is fascinating and highly entertaining. And tells the story of the evolution of evolution as it has never been told before...
Terry Pratchett - Ian Stewart - Jack Cohen - The Science of Discworld
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 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...
Jack Cohen - Ian Stewart - Evolving the Alien
What would life on other planets look like? Forget the little green men, alien life is likely to be completely unrecognisable - we haven't even discovered all the life on our own planet.This visionary book offers some of the most radical but scientifically accurate thinking on the possibility of life on other planets ever conceived. Using broad principles of Earthly biology and expanding on them laterally, Cohen and Stewart examine what could be out there.Redefining our whole concept of what 'life' is, they ask whether aliens could live on the surface of a star, in the vacuum of space or beneath the ice of a frozen moon. And whether life could exist without carbon or DNA - or even without matter at all. They also look at 'celebrity aliens' from books and films - most of which are biologically impossible. Jack Cohen is an 'alien consultant' to many writers, advising what an alien could and couldn't look like. (E.T. go home - you do not pass the test).But this book is as much about the latest discoveries in Earthly biology as well as life on other planets. It's a serious yet entertaining science book, as you'd expect from the bestselling authors of The Science of Discworld.
Terry Pratchett - Ian Stewart - Jack Cohen - The Science of Discworld IV - Judgement Day
A brilliant new Discworld story from Terry Pratchett. 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 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' 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 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.
Terry Pratchett - Ian Stewart - Jack Cohen - The Science Of Discworld II - The Globe
The planet Earth has picked up a parasite life form - elves. They get everywhere. And they like humans to be superstitious, fearful and frightened of thunder. They're after our future and must be stopped... but by who? Enter the wizards of the Unseen University who, in the best-selling Science of Discworld unwittingly created Earth and our own universe. At the time they quite failed to notice humanity. (Well, we've only been around for a million years, so we're easily overlooked...) But now, at last, they've found us. The Globe is a unique book, weaving together a fast-paced Discworld novelette with cutting-edge scientific commentary on the evolution and development of the human mind, culture, language, art, and science. The result - as the wizards grapple with the nature of Good and Evil, and history is rewritten several times over - is a fascinating and brilliantly original view of the world we live in.
