Ten Great Ideas About Chance - Persi Diaconis and Brian Skyrms ***

There are few topics that fascinate me as much as chance and probability. It's partly the wonder that mathematics can be applied to something so intangible and also because so often the outcomes of probability are counter-intuitive and we can enjoy the 'Huh?' impact of something that works yet feels so far from common sense.

I think I ought to start by saying what this is isn't. It's definitely not an introductory book - the authors assume that the reader 'has taken a first undergraduate course in probability or statistics'. And though there's an appendix that claims to be a probability tutorial for those who haven't got this background, it's not particularly reader-friendly - in theory I knew everything in the appendix, but I still found parts of it near-impossible to read.

As for the main text, if you pass that first criterion, my suspicion is that, like me, you will find parts utterly fascinating and other parts pretty much incomprehensible. The authors swoop between engaging philosophical discussions of the nature of probability and the frequentist v Bayesian debate and descriptions of pretty heavy duty mathematical thinking on specific aspects of probability and its applicability.

Some of the 'ten great ideas' are fairly straightforward, whether we're talking the early work from Cardano or Bayes' theorem (though, again, the way it's presented here is really surprisingly impenetrable, when it could be covered for more accessibly). But others really strain the non-mathematician's brain. And these can come quite early. The second chapter opens 'Our second great idea is that judgements can be measured and that coherent judgements are probabilities.' Although I felt I ought to be able grasp what was going on here, I found that the way it was presented went totally over my head. It's just not very well written.

So, unless you know much of this stuff already, the chances are you will find some parts hard going - but I found it well worthwhile using the old university student approach of 'just let it wash over you and you'll get to a bit where it starts to make sense again'. This, for me, was the way to cope and the parts I could get my head around were really interesting. I just wish there had been someone involved in the project who knew how to communicate to ordinary readers.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here.  We are then presented with eight paradoxes, each of which gives some insights into aspects of t...

Einstein's Fridge - Paul Sen ****

In Einstein's Fridge (interesting factoid: this is at least the third popular science book to be named after Einstein's not particularly exciting refrigerator), Paul Sen has taken on a scary challenge. As Jim Al-Khalili made clear in his excellent The World According to Physics , our physical understanding of reality rests on three pillars: relativity, quantum theory and thermodynamics. But there is no doubt that the third of these, the topic of Sen's book, is a hard sell. While it's true that these are the three pillars of physics, from the point of view of making interesting popular science, the first two might be considered pillars of gold and platinum, while the third is a pillar of salt. Relativity and quantum theory are very much of the twentieth century. They are exciting and sometimes downright weird and wonderful. Thermodynamics, by contrast, has a very Victorian feel and, well, is uninspiring. Luckily, though, thermodynamics is important enough, lying behind ...
