By Light Alone (SF) - Adam Roberts ****

I have only relatively recently discovered Adam Roberts, with the likes of Jack Glass and The Thing Itself, but every one of his books I've read has been excellent, so it seemed time to start filling in the gaps.

I went for By Light Alone because of its interesting sounding premise. It's a cracker (as they say). The idea is that science has produced a mechanism where people can get all the energy they need from sunlight, thanks to a bug that turns their hair into super-photosynethic light absorbers. All they need to live is some water and a few essential nutrients. A clever (if technically verging on the impossible) idea, certainly. But where Roberts triumphs is in going into the unexpected implications of the change - the absolute heart of what makes science fiction, and which so few literary types who do SF down, and think it's all about spaceships and ray guns, appreciate.

One implication considered is that for the first time ever it's possible to have a group of people who have literary no money at all. Not just poor but literally penniless. Roberts also examines the possibilities for male/female distinctions, and how a small group of wealthy people might consider those who have the special hair to be a subspecies, and to conspicuously wear their hair short to emphasise they don't need it.

The book is divided into four parts, each seen from a different (but linked) individual's point of view. At the heart of the book is the story of a privileged family whose daughter is taken from them on a skiing holiday. They assume initially it is as a hostage, but the authorities gradually explain that something much darker is behind it.

The one fault I would say that the book has is that the forth segment, which is the longest, seen from the viewpoint of the captured daughter, is the least effective. It's partly because the environment she is in forces a slow, plodding development, with occasional dramatic outbreaks of violence, but also because it just doesn't work quite as well as the other sections. It's good, but the others are brilliant.

If you want to see what good, modern science fiction is like - or are looking for a new author to branch out into, Adam Roberts is an obvious choice. I wouldn't go straight to his latest, The Thing Itself, as it is his most complex book, but either By Light Alone or Jack Glass would make an excellent way in. Recommended.

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...
