Middle World – Mark Haw ****

This is a classic case of judging a book by its cover. I have been putting off reviewing this book for ages, because, frankly it looks very dull and the title, sounding like a compromise between Tolkein and Middle England, is equally uninspiring. I should have followed the old adage, and not been too influenced by the cover, because it’s an excellent read.

In part it’s the subject. Mark Haw starts with Brownian motion and goes on to explore the nanoscale world of (mostly natural) objects too big to be quantum particles, but too small to be everyday macro world – they tend to be constantly in motion, buffeted around by the atoms that are hitting them, always in a random dance.

The two most interesting parts for me were getting some information about Robert Brown, who I’d come across but hadn’t really absorbed any details about, and the remarkable biological machines on this scale that make muscles work, do jobs in cells and much more. The way these make use of the random walk of the ‘middle world’ rather than fighting it is fascinating.

Mark Haw writes in a very approachable fashion – certainly without any of the problems many scientists writing on their topic have. If this book has any faults it’s that it is too short – very rarely a complaint from me, but it’s true here – and that he can try just a bit too hard to be a bit of lad and in touch, meaning that just occasionally we get the sort of sweeping generalization in a biographical/historical statement that’s typical of a cheap TV documentary – but that apart it’s excellent. It might be too late to recommend, but I hope it’s not – go for it, it’s excellent!

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...
