Star Power - Alain Bécoulet **

This book was a disappointment - more on that in a moment. The aim is to give us the picture of the development of nuclear fusion as a power source leading up to the latest and best incarnation of a fusion reactor, ITER. In principle, fusion offers us the best option to balance out the variability of wind and solar - an on-demand energy supply that is green and doesn't produce the same level of nuclear waste as fission. But the timescales are mind-numbing.

Fusion energy has already been in development for over 60 years. ITER, a project that was first conceived 34 years ago is expected to fully operational by 2035 with experiments continuing for 20 years. This would take it to 67 years from first conception. And ITER isn't even a prototype for a working power station - that's the next stage. In part, Alain Bécoulet does give us a picture of why things have taken so long - because, for example, handling the lively, ultra hot plasma at the heart of a magnetic confinement reactor has proved far trickier than was first anticipated. But even so, given the urgency of getting away from fossil fuels, speed is of the essence, yet Bécoulet hardly mentions the many competitors to the ITER route (the equivalent of only mentioning NASA and omitting SpaceX for example), and doesn't explain why those in the mainstream programme haven't done far more parallel development to get things moving quicker.

The detail on the problems with handling plasma (and how it wasn't anticipated) is the highlight of this book - I haven't seen such detail elsewhere. But unfortunately, Star Power falls down as a readable text. There are three broad issues - the use of language (which may be influenced by the book being translated from the original French), huge tracts of vagueness interspersed with unnecessary technical detail, and lack of an effective structure to carry the narrative through.

A random example of the clunky prose and vagueness (not the worst) would be 'Everything would turn out well in this best of turbulent worlds if efforts to achieve optimal plasma performance were not limited by nature - to wit, by certain fundamental mechanisms at work involving currents, pressures, and magnetic fields. We can approach this vexed field of endeavour by calling to mind a few scenes familiar from high-school science classes.'

In the end, although I wanted to know what this book has to say, I didn't enjoy reading it. I ploughed on regardless, but it wasn't a great experience.

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...
