Serendipity - Telmo Pievani (trans. Michael Gerard Kenyon) ***

There is no doubt that serendipity is a delightful word - and equally no doubt that its meaning of making accidental positive discoveries is an apt one for science. It's quite fun to hear about unexpected finds, whether it's the famous ones like penicillin or perhaps less well known discoveries from PTFE to saccharin (neither of which are considered here).

It is, however, a rather delicate concept - not suited to a heavy duty approach, which is arguably what Telmo Pievani gives it in this slim (but surprisingly long feeling) book. A non-fiction writer is always faced with the temptation to give far more detail on a topic that interests them than necessarily engages their readers. Here, Pievani goes to town on the origins of the word 'serendipity'. It is, indeed vaguely interesting that it came from an old tale about the 'Three Princes of Serendip', but the level of detail we're given on the ancient Persian set of stories this originates from verges on the excruciating - about 20 pages dedicated to little more than etymology, and getting on for 50 pages of meandering before we touch much science.

We do get some scientific discoveries to justify the subtitle of 'the unexpected in science' - but even here it's arguable whether some of the discoveries, such as pulsars really could be considered serendipity. It's true that they were not looking for pulsars (how could they, when no one knew they existed), but they were looking - Bell's discovery was not an accident in the conventional sense of the word. When we do hit on true serendipity, the storytelling is sparse, often getting through it in a page or so before getting back to meandering.

I'm sure this book will appeal to some readers, but I found it verging on the pompous and rarely interesting.

The Art of Uncertainty - David Spiegelhalter *****

There's something odd about this chunky book on probability - the title doesn't mention the P word at all. This is because David Spiegelhalter (Professor Sir David to give him his full title) has what some mathematicians would consider a controversial viewpoint. As he puts it 'all probabilities are judgements expressing personal uncertainty.' He strongly (and convincingly) argues that while the mathematical approach to probability is about concrete, factual values, outside of the 'natural' probabilities behind quantum effects, almost all real world probability is a subjective experience, better described by more subjective terms like uncertainty, chance and luck. A classic way to distinguish between those taking the frequentist approach to probability and the Bayesian approach is their attitude to what the probability is of a fair coin coming up heads or tails after the coin has been tossed but before we have looked at it. The frequentist would say it's def

Everything is Predictable - Tom Chivers *****

There's a stereotype of computer users: Mac users are creative and cool, while PC users are businesslike and unimaginative. Less well-known is that the world of statistics has an equivalent division. Bayesians are the Mac users of the stats world, where frequentists are the PC people. This book sets out to show why Bayesians are not just cool, but also mostly right. Tom Chivers does an excellent job of giving us some historical background, then dives into two key aspects of the use of statistics. These are in science, where the standard approach is frequentist and Bayes only creeps into a few specific applications, such as the accuracy of medical tests, and in decision theory where Bayes is dominant. If this all sounds very dry and unexciting, it's quite the reverse. I admit, I love probability and statistics, and I am something of a closet Bayesian*), but Chivers' light and entertaining style means that what could have been the mathematical equivalent of debating angels on

Math for English Majors - Ben Orlin *****

Ben Orlin makes the interesting observation that the majority of people give up on understanding maths at some point, from fractions or algebra all the way through to tensors. At that stage they either give up entirely or operate the maths mechanically without understanding what they are doing. In this light-hearted take, Orlin does a great job of taking on mathematical processes a step at a time, in part making parallels with the structure of language. Many popular maths books shy away from the actual mathematical representations, going instead for verbal approximations. Orlin doesn't do this, but makes use of those linguistic similes and different ways of looking at the processes involved to help understanding. He also includes self-admittedly awful (but entertaining) drawings and stories from his experience as a long-time maths teacher. To make those parallels, Orlin refers to numbers as nouns, operations as verbs (though he points out that there are some flaws in this simile) a
