Experiencing the Impossible: Gustav Kuhn ***

I have to admit I find magic acts rather tedious entertainment - but I do enjoy trying to work out how the trick was done and then (ideally) finding out how it really was undertaken - so I was fascinated by the idea of a book that claims to cover 'the science of magic'. (By magic, I should stress, I don't mean the fantasy sorcery version, but the very down-to-earth engineered version used in magic shows.) This handsome book proved to be a distinct curate's egg: there were sections I pretty much skip read as they were somewhat dull, but other parts that really captured my attention.

The reason that some sections don't work so well was the classic academic writer's problem of not realising the importance of narrative and storytelling (which you'd think a practising magician like Gustav Kuhn would realise). The book comes alive when we are told about specific tricks or people or situations, but sometimes it becomes a collection of facts, a lecture on, say, a particular psychological trait, and then it can lose the reader's attention.

It's not that the psychology parts aren't interesting - and inevitably, apart from engineering, most of the 'science of magic' is about psychology and how the brain works (and doesn't) - but they need to be presented with much more context and more tying back to the magic that they are supposed to be illustrating. Similarly, it's not that the science is too heavy - if anything, we don't get enough of it. So, for example, Kuhn introduces a theory of Bayesian misdirection which I absolutely loved as a concept, but wasn't able to read much about.

If you read the book to get the lowdown on how all the famous tricks work, you will be disappointed. Kuhn does explain a few very basic tricks, but mostly brandishes the magician's traditional veil of secrecy. This is a real shame and is another reason the book doesn't work as well as it could. You don't explain science by saying 'the researchers did an experiment, but I'm not going to tell you how it worked, just what it looked like' - but that's exactly what happens here. A great example is Kuhn's use of a Derren Brown illusion, where someone was given the choice of any toy in the huge toy store Hamleys, and Brown apparently predicted what the choice would be. Kuhn tells us that Brown 'explained' the trick by telling us it was due to repeated suggestions - but that this explanation doesn't hold up. We're then told 'Brown is one of my favourite magicians and I have no intention of revealing how his trick is done...' - but that's exactly what's required to make the book work. There's too much tease with no reveal.

One other thing that I was surprised wasn't covered, perhaps because of the author's obvious love for magic, is its rapid decline as a popular adult entertainment. A couple of decades ago, magic shows were primetime TV fixtures. Now, magic tends to be much more niche. It may be that as we are so used to amazing CGI, we don't really care about illusion. Or something else. It would have been interesting to have seen a professional analysis of this.

I don't want to give the impression that this book is devoid of interesting content. I repeatedly came on sections which really grabbed my attention, primarily those built around actual magical tricks. But it could have been so much better.

Superior - Angela Saini *****

It was always going to be difficult to follow Angela Saini's hugely popular Inferior, but with Superior she has pulled it off, not just in the content but by upping the quality of the writing to a whole new level. Where Inferior looked at the misuse of science in supporting sexism (and the existence of sexism in science), Superior examines the way that racism has been given a totally unfounded pseudo-scientific basis in the past - and how, remarkably, despite absolute evidence to the contrary, this still turns up today.

At the heart of the book is the scientific fact that 'race' simply does not exist biologically - it is nothing more than an outdated social label. As Saini points out, there are far larger genetic variations within a so-called race than there are between individuals supposedly of different races. She shows how, pre-genetics, racial prejudice was given a pseudo-scientific veneer by dreaming up fictitious physical differences over and above the tiny distinct…

Where are the chemistry popular science books?

by Brian Clegg
There has never been more emphasis on the importance of public engagement. We need both to encourage a deeper interest in science and to counter anti-scientific views that seem to go hand-in-hand with some types of politics. Getting the public interested in science both helps recruit new scientists of the future and spreads an understanding of why an area of scientific research deserves funding. Yet it is possible that chemistry lags behind the other sciences in outreach. As a science writer, and editor of this website, I believe that chemistry is under-represented in popular science. I'd like to establish if this is the case, if so why it is happening - and what can be done to change things. 

An easy straw poll is provided by the topic tags on the site. At the time of writing, there are 22 books under 'chemistry' as opposed to 97 maths, 126 biology and 182 physics. The distribution is inevitably influenced by editorial bias - but as the editor, I can confirm …

The Art of Statistics - David Spiegelhalter *****

Statistics have a huge impact on us - we are bombarded with them in the news, they are essential to medical trials, fundamental science, some court cases and far more. Yet statistics is also a subject than many struggle to deal with (especially when the coupled subject of probability rears its head). Most of us just aren't equipped to understand what we're being told, or to question it when the statistics are dodgy. What David Spiegelhalter does here is provide a very thorough introductory grounding in statistics without making use of mathematical formulae*. And it's remarkable.

What will probably surprise some who have some training in statistics, particularly if (like mine) it's on the old side, is that probability doesn't come into the book until page 205. Spiegelhalter argues that as probability is the hardest aspect for us to get an intuitive feel for, this makes a lot of sense - and I think he's right. That doesn't mean that he doesn't cover all …
