Smarter: the new science of building brain power – Dan Hurley ****

The knee-jerk reaction on seeing this book was ‘it’s going to be rubbish’, as it is widely publicised that most commercial ‘brain training’ products have no more value than any activity that keeps the mind active, from reading a book to chatting to a next-door neighbour. And while an active mind is valuable in keeping alert in old age, it gives no advantages in terms of ‘brain power’ whether you  consider that as IQ or something a bit more subtle.
In fact, I needn’t have worried, because Dan Hurley is aware of this, and is approaching a very specific aspect of training, using an intense methodology, which has shown some interesting results in proper scientific testing.
Along the way, he decides to see if he can enhance his own brain, so takes a MENSA test, then engages in as many brain enhancing activities as he can before being re-tested – from physical exercise to a nicotine patch – which have been shown to have some benefit in mental acuity. Perhaps the most interesting bit of the book is where he assesses all the different possibilities, dismissing some (eating the right thing, apart from drinking coffee, for instance) and taking others on board, all based on our best current science.
Another favourite is the final section, where we see played out a significant battle between academics, some sticking to the traditional argument that all training does is train you to be better at that particular test, some open to a wide range of possibilities. It’s interesting, apart from anything else, to show just how different theories are sometimes handled in the academic community.
The only part of the book I felt didn’t quite work was a longish section on Down’s syndrome, not because it wasn’t important or interesting, but because it didn’t quite fit with everything else, centred around Hurley’s personal test, and the result was that overall the book’s structure seemed a little haphazard.
As long as you don’t object too much to the author’s slightly patronising magazine writer’s style, that makes him feel the urge to put in a number of unnecessary personal descriptions (take for instance ‘Tall, blond and good-looking: in another words, a typical Swiss’), this should prove a fascinating read on a truly interesting topic.

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...
