Thinking Big - Clive Gamble, John Gowlett and Robin Dunbar ****

When I was young, my main exposure to popular science was through my Dad's collection of Pelican paperbacks, where academics expounded on the likes of animals without backbones or some archeological wonder such as Howard Carter's discovery of Tutankhamen's tomb or Schliemann's adventures uncovering Troy. On the whole I preferred the archaeology titles, as they tended to have more of a story - but when I read Thinking Big, I was plunged back into that world.

The topic helps - we've got a combination of archaeology, palaeontology and psychology here - but there's also something about the feel of the book. The authors are generally rather serious about what they're doing, there's that same small, finicky print and the reader does have to work reasonably hard to get much out of it.

Part of the difficulty is that the thread of the book is quite meandering and the underlying science sometimes feels distinctly vague. At the core is the 'social brain hypothesis' - the idea that the size of the brain (or to be precise, certain aspects of the brain) is correlated to social group sizes and that the story of the evolution of homo sapiens is driven strongly by these social group sizes and their implications.

The reason the science can seem vague is that inevitably there is a lot of hypothesising going on here. Apparently many archeologists don't like the approach taken and prefer to adopt a WYSWTW - What You See is What There Was - mantra. The trouble with this is that it is guaranteed to be wrong, where the approach taken by the authors only might be wrong. the WYSWTW fans simply deny the existence of anything in prehistoric society that doesn't leave concrete remains. But you can't find a fossilised belief, a mummified song or the remains of a conversation - so this leaves their picture of the life of these early hominins and humans that is very sparse and boring.

The alternative approach taken in this book is to accept that there was more going on than will leave remains and to try to make deductions from how developing brains will, for example, be able to deal with more levels of intention (I know that you are aware that she is lying, for example) and will be reflected in different group sizes, with the significant implications these will have for culture. Throw in how factors such as religion, music and language can also impact the effectiveness of social groups and there seems to be a way here to feel crudely back to the social life of our ancestors.

Although it's not written in a hugely approachable style - too academic in approach - and the driving concept suffers from an inevitable degree of vagueness, this feels like an important piece of work and one that anyone with an interest in early human and pre-human society should add to their reading list.

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...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms.  On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines  when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
