A Chorus of Big Bangs - Adam Susskind ***

This is an oddity, which is trying to do something that scientists usually avoid at all costs: making us think about what we take on faith when we consider cosmology. If the 'F' word is a problem for you, I wouldn't bother to read any further, but Adam Susskind is certainly right to point out it is not just the religious part of the world population who rely on faith - to take the atheist standpoint that most scientists espouse also requires faith in the adequacy of sometimes tenuous theories when dealing with a science as hands-off as cosmology.

Susskind does a good job of identifying a range of cosmological theories that have been repeatedly patched up when holes have been found, to the extent that some now feel quite flaky. Many of the theories Susskind identifies are indeed currently problematic, but easily replaced by a better future scientific theory - for example dark matter, dark energy and inflation. Others are more fundamental and we genuinely don't have a particular good approach, for example for how the universe came into existence (unless we follow Fred Hoyle's lead with the steady state theory and find a mechanism for an eternal universe) or the remarkable fine tuning of the universe, for which the only scientific 'explanation' I've seen to date is the multiverse theory, which Philip Goff's Why? demonstrates so impressively is a misuse of probability.

A Chorus of Big Bangs is not without issues. It's self-published and it feels like it. The book is very thin with just 83 pages, and Susskind admits he has no science background, basing a lot of what he includes on TV science documentaries, which can be distinctly trivial in their approach. It's clear he is coming at this from a religious standpoint, though, to his credit, he does not explicitly bring this in - he merely points to the big holes that remain in cosmology. I think it might have had a better audience without that subtitle.

If I'm honest, I expected to find this book totally lacking in value, but it was surprisingly useful to have the various potential problems highlighted, using quotes from well-known scientists along the way to emphasise this.

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...
