Science books are not meant to be this interesting. I found it hard to put down, and read it in a little over a week. By tackling science chronologically, the author presents scientific discoveries like a 'whodunnit' - making the subject intrinsically interesting. Compare this with the way science is taught in schools - to use the 'whodunnit' analogy, pupils are taught that 'x' murdered victim #1, 'y' murdered victim #2 etc. The latter approach strips the subject of a major part of its interest. There are some great little revelations, such as how the ultra-tedious Principle of Conservation of Energy was (so to speak) 'discovered' (it involves arteries, veins & leeches), and the significance of the structure of the atom (e.g. the chair you are sitting on is mostly made of nothing - reflecting the massive gap between the electrons & nucleus. I never thought of it like that. Wow!) The author even makes quantum mechanics simple to understand. Wow! (There I go again). This is only the second ever Amazon review I have written. Why did I bother? Because the book enthuses me.
