Beam – Jeff Hecht ***

Beam‘s subtitle is ‘the race to make the laser’ and this was a story that was crying out for a good popular scientific history. Not only is there really interesting physics behind the laser, there was a genuine tense race, strong personalities, bizarre problems with security clearances and more to make for a gripping story.
I’ve come rather late to Beam (first published in 2005) because, frankly, the book doesn’t seem to have been very visible – and I’m afraid I can understand why. Although there are all the elements of a great story there, Jeff Hecht is probably not the right person to tell it. On the physics side, while there is a lot of detail of the precise excitation processes required for masers and lasers, there isn’t really enough background on quantum physics to give it context.
As for the story itself, the book suffers from kitchen-sink-itis. Hecht seems to feel it necessary to mention ever single tiny contribution to the research, whether or not it had a direct impact on the key players. And though the story really does get interesting when, for instance, we get onto Gordon Gould’s you’d-laugh-if-you-didn’t-cry security problems that meant he wasn’t able to read his own work, much of the storytelling gets horribly bogged down and repetitive, making it hard to follow the narrative.
The final problem is limiting the book to the race to create the first laser – it would have had a wider interest if Hecht had brought in the development of the solid state lasers we all have littering our homes in CD players and the like.
All in all, there is plenty of good stuff here, and I’m not aware of anyone else who has told the story in such detail, but you have to work quite hard to get to the nuggets.

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...
