Destroyer of Worlds - Frank Close *****

At first glance at the title you might assume that this book is another Oppenheimer biography - and of course he features - but it's far more. Frank Close starts with a large pre-bomb section taking us through the development of nuclear physics. Some aspects of this are familiar, such as Rutherford and the nucleus, others less so - it's great, for example, to have story of discovery of the neutron as it has rarely been covered and was a real scientific race, laden with misunderstanding and last minute experiments. 

There are a lot of names presented here and it would be easy to turn this into a tedious collection of who did what, but Close is skilful enough to make the telling of the story gripping, and brings in some less familiar characters, such as Majorana and Compton to season the familiar names. Close excels at digging out aspects of the history that were a little different from the way the stories are often told, for example casting doubt on the details of Szilard's alleged revelation of chain reactions while crossing the road into Russell Square in London.

The whole book could have been dedicated to the increasing knowledge of the nucleus and its potential for generating energy (Rutherford's famous quote 'Anyone who looks for a source of power in the transformation of atoms is talking moonshine' is also given a novel context), but Close brings in the details of both the initial fission bomb science and a considerable amount on the extension to fusion (H-bombs) both in the US and in Russia.

At one point I did raise an eyebrow - I don't know if it's because Close is an Oxford man to the core, but he does have a moment of architectural madness, first describing a Cambridge college’s courts as quadrangles (many, but not all. technically are, but it’s not what they are called), then apparently referring to the elegant stone entrance of the Cavendish Laboratory as 'a red brick building whose windows could have doubled for offices in a Northern mill town.' Admittedly there is a red brick building further down Free School Lane, but this wouldn't feature in the walk described and it is the engineering labs, not the Cavendish (also the brick building is handsome in its own right).

My only other slight moan is that the name of the book suggests an attempt to hitch onto the publicity arising from the Oppenheimer movie, given its status as an extract from Oppenheimer's famous quote from the Bhagavad Gita 'Now I am become Death, the Destroyer of Worlds' - but Oppenheimer himself only gets a few passing lines - and Close with typical verve adds in the comment of another watcher at the Los Alamos test '"Now we are all the sons of bitches," which more prosaically described what the scientists' achievement would make them.' Minimal reference to Oppenheimer is entirely legitimate for a book that concentrates on the science behind nuclear weapons (and power) rather than the organisational details of the Manhattan Project, which has been covered at length elsewhere - but it does feel a touch misleading.

An excellent combination of nuclear physics primer and history of the developing science of nuclear power and weapons through to the mid-sixties. One of his best yet.

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...
