Void (SF) - Veronica Roth ****

This is a single longish short story in Amazon's Far Reaches collection - and proved pleasantly engaging. I hadn't come across Veronica Roth before (apparently she wrote the Divergent series) but she has a light, readable style in this rather classic setting of 'working class folk on the spaceship'.

This is the home of Elton John's Rocket Man, which was very common in 1950s SF films and lasted through to Star Trek, when the writers were still essentially modelling their crews on nautical vessels, with their inevitably working class characters to do the dirty jobs. In Void, we meet Ace, one of the team who does onboard maintenance on a craft that shuttles between Earth and Proxima Centauri. She and her colleagues deal with everyday problems like malfunctioning toilets. You would probably think that by the time we can build near-light speed ships, we could also make a robot that could mend a toilet - and real life experience of space travel so far is that there is no real role for these figures, but it's a fun return to a classic concept.

Central to the plot, which is a sort of murder mystery, is the reality that because it's a near-light speed ship, the crew are travelling into the future compared to Earth, thanks to time dilation. I think Roth gets the physics a bit wrong - we're told that someone moves ahead decades in a single return trip to Proxima (rather oddly, Roth uses the shortening Centauri, which could apply to all sorts of bodies) - given a round trip is 9 light years, I can't see how the dilation can be more than 9 years - but it's a picky detail.

Like most attempts to do a murder mystery in a short story, there's not enough room to give all the twists and red herrings that really make such a tale, but Roth does a good job of exploring the life of a worker on such a ship, and the way that time dilation can mess around with their worldview. Fun.

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 ...
