The Science of Discworld
by Terry Pratchett, Ian Stewart, and Jack Cohen

Alternating chapters of fantasy and advanced science. The science chapters are very educational and up-to-date as of 1999. The fantasy chapters are amusing. Overall it presents a picture of life in an inhospitable universe.

It has quite a few good lines on a variety of subjects. For example, when a process such as life stops, itís no longer there:

ďWhen you stop beating an egg, there isnít some pseudo-material essence-of-eggbeater that passes on to something else. You just arenít turning the handle anymore.Ē p. 179.
The book looks as life from the perspective of wizards who live in a universe built on a much larger scale and operating under the laws of magic. Our universe is in a glass ball about one foot wide, which they are observing periodically in their Unseen University.

Year Read: 2001
