                    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... 
                  In 
                    Darwin's Watch Victorian England has stagnated and 
                    the pace of progress would embarrass a limping snail. Unless 
                    something drastic is done, there won't be time for anyone 
                    to invent spaceflight and the human race will be turned into 
                    ice-pops.  
                  Why, 
                    though, did history come adrift? Was it Sir Arthur Nightingale's 
                    dismal book about natural selection? Or was it the devastating 
                    response by an obscure country vicar called Charles Darwin, 
                    whose best-selling Theology of Species made it impossible 
                    to refute the divine design of living creatures? Either way, 
                    it's no easy task to change history, as the wizards discover 
                    to their cost. Can the God of Evolution come to humanity's 
                    aid and ensure Darwin writes a very different book? And who 
                    stopped him writing it in the first place? 
                  Yes, 
                    the follow up to The 
                    Globe 
                    is just as wild and wacky as we've come to expect from this 
                    series. From time-travel to philosophical dilemmas, quantum 
                    physics to the 'cause and effect' effect, Terry Pratchett, 
                    Ian Stewart and Jack Cohen turn the latest scientific research 
                    into an easy-to-understand journey through the development 
                    of the planet Earth and the human race. 
                  This 
                    book tracks the history of geology and DNA, explaining the 
                    concepts of black holes and infinity and refuting some of 
                    the top theories of current scientific thinking (from James 
                    Barbour's timeless probability mist to the mathematical resolution 
                    of Zeno's Arrow paradox via Hamiltonian mechanics). 
                  And 
                    that's one of the impressive things about this release - it 
                    brings science down to a level (without been patronising) 
                    that everyone can understand. 
                  Another 
                    fantastic addition to the Science of Discworld series.
