Molecules: A Very Short Introduction - previously sold as Stories of the Invisible: A Guided Tour of Molecules - is not so much an introduction to molecules as an introduction to biochemistry, the molecules of life. This is something Ball states from the outset, and with the boundary between chemistry and biology becoming ever more blurred, it's an understandable approach to take. We are, after all, now using natural molecules in technology as well as synthetic molecules to preserve what we deem 'natural'.
The book starts with the very basics - how atoms are joined together and why we can't 'see' them in the traditional sense, before quickly advancing to biochemistry and the complex molecules so vital to the body. As the author himself says, molecular biology is not difficult in the way that theoretical physics is difficult - the concepts are not unfamiliar, abstract or mathematically hard. The difficulty arises because there is so much going on all at once, and so many levels to the hierarchy.
So while Ball's writing is, for the most part, clear and full of personality, some of the processes he describes are unavoidably complicated and a lot to take in. As a non-specialist, I came away remembering the gist, if not all the detail. One of the reviews (Chemistry in Britain) described Ball's science as 'encyclopaedic'. That's definitely a word that springs to mind.
The choice of topics is good, and if, like me, you're new to the subject, you'll find it mind-boggling to learn just how finely-tuned our bodies are - all the checkpoints, safety mechanisms, back-up plans and careful record-keeping that occurs. Also the illustrations here are genuinely interesting and not just irrelevant ways to break up the text, as has been the case with certain other entries in this series. (Speaking of other entries, I can recommend the author's follow-up,
The Elements: A Very Short Introduction.)
All in all, this is an impressive attempt by Ball to lead the non-specialist reader through a labyrinthine but vital area of science. You may not keep it all in your head, but you'll come away with a better sense of the kind of finely-tuned processes required to keep the big things functioning normally.
