A Brain for Numbers: Andreas Nieder ***

In dramas it's not usual for someone dumping a partner to say 'It's not you, it's me,' - and that's how I felt about this book. I'm sure some readers would find it really interesting, but it didn't work for me.

I think the main problem is that that I'm interested in maths, but not so much in how human and animal brains handle numbers. So I found the opening and closing chapters, which deal with the nature of numbers (specifically zero in that closing chapter) I enjoyed, but the vast majority of the book explores the design of experiments to try to understand how animals perceive numbers (or don't), what we can learn from them, and how animals' and our brains react to numbers.

As soon as I see a map of the brain, I'm afraid I turn off - there's an element of Richard Feynman's famous complaint about biology students wasting their time learning the names of all the bits in a cat's nervous system. However, if you are interested in how the brain responds to numbers (we're talking specifically whole counting numbers here), then I've no doubt the book would prove more interesting.

I don't think it helped that there's some quite heavyweight language used, which my eyes tend to bounce off. After a while I struggle to keep going when this is the case. I've just opened the book at random and the first sentence I came across was 'This study showed stable neural representations of sequential numerosities [sic] across visual and auditory modalities.'

For the right audience - I suspect biology students wanting to explore this area further - this is undoubtedly a great book. But it didn't do it for me.

The Infinite Book – John D. Barrow ****

Authors are often asked to review books on a topic they’ve written on themselves. The reasoning is sensible – they ought to know something about the subject – but there’s always that uneasy suspicion that there’s going to be a bit of bias creeping in. So I think it’s only fair to admit up front that I have written a book on infinity (of which more later). Infinity is a wonderful subject, because it’s intimately mind-bending (if the combination sounds paradoxical, that’s what infinity is all about) and gives you the chance to pull in all sorts of different concepts and assocations along the way, something Barrow does with great gusto. There’s a surprisingly large amount of coverage here for God, and for the universe, and the book jumps around from Aristotle to Hilbert’s Infinite Hotel (explained at great length), from the paradoxes of infinite sets to the paradoxes of time travel. Overall it’s an enjoyable journey that gives plenty of opportunity to be amazed and surprised. The...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

The Random Universe - Andrew Jaffe *****

This is an absolutely fascinating book for anyone interested in the way that science really works, bearing in mind the difficulties of having to base our models and theories on induction. Andrew Jaffe introduces the difficulties we face when trying to take a scientific view because largely we are dependent on induction: predicting the future from what has previously been observed. He explores what probability is, the two key ways of looking at it (frequentist and Bayesian) and how scientists use (or misuse it) to work out the implications of their experiments for hypotheses. This is then expanded into looking at the nature of scientific models and the philosophy of science before heading out to entropy, quantum randomness and attempting to achieve meaningful cosmology with its potential dearth of evidence. The topic might sound a little dry, but in fact Jaffe does it with good humour and a very readable style. For example, he uses measuring his daughter's height by making marks on...
