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 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 Infinity Machine - Sebastian Mallaby ****

It's very quickly clear that Sebastian Mallaby is a huge Demis Hassabis fan - writing about the only child prodigy and teen genius ever who was also a nice, rounded personality. After a few chapters, though, things settle down (I'm reminded of Douglas Adams' description of the Hitchhiker's Guide to the Galaxy ) and we get a good, solid trip through the journey that gave us DeepMind, their AlphaGo and AlphaFold programs, the sudden explosion of competition on the AI front and thoughts on artificial general intelligence. Although Mallaby does occasionally still go into fan mode - reading this you would think that AlphaFold had successfully perfectly predicted the structure of every protein, where it is usually not sufficiently accurate for its results to have direct practical application - we get a real feel for the way this relatively unusual company was swiftly and successfully developed away from Silicon Valley. It's readable and gives an important understanding of...

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...
