I am interested in the great mysteries of the universe, though I certainly am no physicist or Astronomer Royal. The last time I seriously had to deal with physics was for my A level exams 15 years ago, which I miraculously scraped by with a C. Years later, I find myself greatly interested in the wonders of space, time and matter and am trying to make up for the 'lost years' (including those in secondary school when I hardly knew what I was doing). A User's Guide to the Universe does the job of reintroducing me to science perfectly. This is a wonderful, engaging, humourous, well-explained account of the earth and everything that makes up or surrounds us. It is not aimed at mathematicians or physicists and there are no equations in sight (Hallelujah!) Well, apart from e=mc2 which the authors get out the way in the first couple of pages. All the basic concepts of atoms, quantum theory, black holes, etc are explained thoroughly, with everyday analogies but without the mathematical jargon. If you're just an ordinary person who'd like to know a little bit more about how things work, but fear incomprehensible explanations and formidable equations, you will greatly enjoy this book. It's the thriller of science books which had me up until 2 am this morning because it's so engrossing. I am forever grateful to the authors for writing a science book in language accessible to an ordinary person!
