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.

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 ...

Introducing Artificial Intelligence – Henry Brighton & Howard Selina ****

It is almost impossible to rate these relentlessly hip books – they are pure marmite*. The huge Introducing … series (a vast range of books covering everything from Quantum Theory to Islam), previously known as … for Beginners , puts across the message in a style that owes as much to Terry Gilliam and pop art as it does to popular science. Pretty well every page features large graphics with speech bubbles that are supposed to emphasise the point. Funnily, Introducing Artificial Intelligence is both a good and bad example of the series. Let’s get the bad bits out of the way first. The illustrators of these books are very variable, and I didn’t particularly like the pictures here. They did add something – the illustrations in these books always have a lot of information content, rather than being window dressing – but they seemed more detached from the text and rather lacking in the oomph the best versions have. The other real problem is that...

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, ...
