A Short History of Nearly Everything is Bill Bryson's quest to find out everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us.
His challenge is to take subjects that normally bore the pants off most of us, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. It's not so much about what we know, as about how we know what we know. How do we know what is in the centre of the Earth, or what a black hole is, or where the continents were 600 million years ago? How did anyone ever figure these things out?
On his travels through time and space, Bill Bryson takes us with him on the ultimate eye-opening journey, and reveals the world in a way most of us have never seen it before.
Twoflower was a tourist, the first ever seen on the Discworld. Tourist, Rincewind decided, meant idiot.
Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place which might sound and smell very much like our own, but which looks completely different. It plays by different rules. Certainly it refuses to succumb to the quaint notion that universes are ruled by pure logic and the harmony of numbers.
But just because the Disc is different doesn't mean that some things don't stay the same. Its very existence is about to be threatened by a strange new blight: the arrival of the first tourist, upon whose survival rests the peace and prosperity of the land. But if the person charged with maintaining that survival in the face of robbers, mercenaries and, well, Death is a spectacularly inept wizard, a little logic might turn out to be a very good idea...
