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
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
though, did history come adrift? Was it Sir Arthur Nightingale's

to refute the divine design of living creatures? Either way,

the follow up to The
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.
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).
that's one of the impressive things about this release - it
brings science down to a level (without been patronising)
that everyone can understand.
fantastic addition to the Science of Discworld series.
