The Secret Lives of Molecules - Kathryn Harkup ****

A number of years ago, the Royal Society of Chemistry began a podcast series called Chemistry in its Element. After completing the 118 episodes for the elements, they branched out into the much richer field of compounds. Kathryn Harkup did not contribute to the series, but this book feels like the next step from those podcasts - bite-sized, enjoyable pieces, in this case looking into each of 52 key molecules. (Even if you've heard the podcasts, the content here is entirely different.) 

Harkup builds into each article a significant story that may be tangential, but makes the subject come alive. So, for example, when talking about sodium chloride - salt - she majors on the significance of salt to humans and Ghandi's protest against the restrictive salt laws in India in the 1930s. As you go through the book you will meet other familiar, big name compounds, such as water, carbon dioxide and sulfuric acid (oddly, this, and sulfur are written as sulphur, despite sulfur now being the standard spelling both according to international chemistry bodies and the RSC). But there are also molecules that are rather more obscure by name if not by function, from lithium iron phosphate to cyanidin and geosmin (evocatively described in the article's subtitle as the smell of rain).

This is a handsome book that would clearly work well as a gift - and it is ideal for dipping into on the commute, though probably not one to read end-to-end in a sitting. It is aimed at an adult audience, but I felt occasionally that Harkup's tone drifted towards writing for younger readers. Take, for example, the final paragraph of the sodium chloride article: 'His actions, and those of his followers, did not end the salt tax, but it was the start of change. The world was now watching what went on in India. And it was clear that the British could not rule there without the consent of the Indian people.' This wording feels pitched at the level of a GCSE textbook, rather than for a more sophisticated reader.

Secret Lives certainly isn't a textbook, though. Harkup does some excellent storytelling and this makes the book an excellent addition to the surprisingly short list of good chemistry popular science titles - for some reason chemistry is definitely the Cinderella science in this regard. Although I was familiar with most of the compounds we met, in every article I learned something new. Harkup has a gift for taking a story in an unexpected direction. So, for example, in the geosmin article, she gets in the Gods of Olympus, the smells of wet earth, bacterial action, the insects called springtails and the human sense of smell. It's a book that's entertaining and informative in equal measures.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life.  To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

The War on Science - Lawrence Krauss (Ed.) ****

At first glance this might appear to be yet another book on how to deal with climate change deniers and the like, such as How to Talk to a Science Denier.   It is, however, a much more significant book because it addresses the way that universities, government and pressure groups have attempted to undermine the scientific process. Conceptually I would give it five stars, but it's quite heavy going because it's a collection of around 18 essays by different academics, with many going over the same ground, so there is a lot of repetition. Even so, it's an important book. There are a few well-known names here - editor Lawrence Krauss, Richard Dawkins and Steven Pinker - but also a range of scientists (with a few philosophers) explaining how science is being damaged in academia by unscientific ideas. Many of the issues apply to other disciplines as well, but this is specifically about the impact on science, and particularly important there because of the damage it has been doing...

The Multiverse - Brian Clegg ****

‘When One Universe Isn’t Enough’, it says on the undeniably eye-catching cover of this book. But why should anyone feel short-changed by the universe we happen to live in? The most obvious answer is if they’re fans or creators of science fiction, who may be distinctly unimpressed by the un-SF-like reality we’re lumbered with. As Brian Clegg points out early in the book, even now  – almost 70 years after the invention of the space rocket – only a tiny fraction of astronauts have ever travelled more than 300 miles from the Earth’s surface. If we’re looking for all those ‘strange new worlds’ that Star Trek promised us, we’re not going to find them that way. What we need is a portal to a parallel universe – or, preferably, a whole collection of them. Since this is a non-fiction book, I hope I’m not spoiling any surprises by saying that we never actually get to this point, or anywhere near it. Like so many other science-fictional ideas that are claimed to have parallels in modern physic...
