Deep Simplicity – John Gribbin ***

There’s something infuriating about chaos theory. It’s a tease. It provokes you to excitement with all its promise of explaining all those complex (yet somehow simple)phenomena like weather and the stock exchange… then it fails to deliver because you can’t really do anything with it.

There are already two great popular science books on chaos. James Gleick’s book Chaos not only brought chaos theory to the popular audience in a powerfully gripping way, it almost defined the genre of crossover popular science books – books in a scientific topic that appealed outside the narrow group of science enthusiasts. The follow-up book, The Collapse of Chaos by Jack Cohen and Ian Stewart goes beyond chaos theory to take in complexity, simplicity and the impact on the real world.

So what’s left? John Gribbin, I think, was lured by the siren song of chaos. It just seems so natural that there ought to be more “chaos and X” books – in this case, chaos, simplicity and life – that it’s easy to ignore the fact there really isn’t much more to say.

Even so, it starts well, and it seemed as if Gribbin was going to give us an enjoyable ride through chaos and the real world, but once he gets into mathematical explanations he gets bogged down and frankly doesn’t do himself justice in putting across what is going on to the general audience – in places it’s downright boring.

There are a few insights here, especially on the overlap between chaos, complexity and the formation of life – as many others have pointed out, DNA is much more a recipe than a blueprint, and the wonder of complexity is the way a very simple set of repeated instructions can result in a complex formation. And there’s some interesting bits towards the end about using complexity effects to detect life on remote planets. But the combination of rather poor exposition of the mathematical aspects of the theory and the feeling that there’s not a lot that’s new makes it difficult to get too enthusiastic.

There’s still something very frustrating about a theory that says “this is why things are like this” but then won’t let you predict anything based on the theory. And frustration is what readers may well end up with. Stick with the classics.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life. To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

Humble Pi - Matt Parker ****

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life. I think the book's title is a little weak - 'Humble Pi' doesn't really convey what it's about, but that subtitle 'a comedy of maths errors' is far more informative. With his delightful conversational style, honed in his stand-up maths shows, it feels as if Parker is a friend down the pub, relating the story of some technical disaster driven by maths and computing, or regaling us with a numerical cock-up. These range from the spectacular - wobbling and collapsing bridges, for example - to the small but beautifully formed, such as Excel's rounding errors. Sometimes it's Parker's little asides that are particularly attractive. I loved his rant on why phone numbers aren't numbers at all (would it be meaningful for someone to ask you what half your phone number is?). We discover the trials and tribulations of getting cal...

Quantum 2.0 - Paul Davies ****

Unlike the general theory of relativity or cosmology, quantum physics is an aspect of physics that has had a huge impact on everyday lives, particularly through the deployment of electronics, but also, for example, where superconductivity has led to practical applications. But when Paul Davies is talking about version 2.0, he is specifically describing quantum information, where quantum particles and systems are used in information technology. This obviously includes quantum computers, but Davies also brings in, for example, the potential for quantum AI technology. Quantum computers have been discussed for decades - algorithms had already been written for them as early as the 1990s - but it's only now that they are starting to become usable devices, not at the personal level but in servers. In his usual approachable style, Davies gives us four chapters bringing us up to speed on quantum basics, but then brings in quantum computing. After this we don't get solid quantum informat...
