The authors state that the aim of this book is to provide the fundamental background knowledge that we need to cope with the complex scientific and technological world of today. The aim of this book is to provide the information you need to become scientifically literate. The book achieves this aim quite nicely, but I can't say the book is particularly exciting to read, especially if you have a science background. This is perhaps something that should be read by someone who isn't too familiar with the different branches of science or someone who wishes to brush up on what they should have learned at school and might have forgotten. This edition has been updated from the first addition.
