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.

Who Invented the Computer? – Ian Watson

Ian Watson is the author of  The Universal Machine  and featured in a recent  Four Way Interview . Saturday June 23 2012 was the centenary of the birth of Alan Turing, the troubled genius who invented the modern computer. Why though do so few people recognize his name and his great achievements? In 1936 English mathematician Alan Turing, published a paper,  On Computable Numbers, with an application to the Entscheidungsproblem . This became the foundation of computing. In it Turing presented a theoretical machine that could solve any problem that could be described by instructions encoded on a paper tape. A Turing Machine could calculate square roots, whilst another might solve Sudoku puzzles. Turing demonstrated you could construct a single  Universal Machine  that could simulate any Turing Machine. One machine solving any problem for which a program could be written – sound familiar? He’d invented the computer. Then,  computers  were peop...

The Star Book – Peter Grego ****

This attractive landscape format book combines an excellent introduction to the stars and basic astronomy with a set of star maps, plus in depth looks at some of the stars featured, with a  bonus section on the solar system. Amazon says it’s a hardback, but in fact it’s a paperback with a rather ingenious cover – you can’t tell from the photo, but the words ‘The Star Book’ are punched through as a series of holes that show the white paper of the next page beneath. Like many astronomy/space books, the cover lacks shelf appeal because it is mostly black, but at least there is some original thought here. Unlike many books in this format which tend to concentrate on the pictures, there is a good deal of excellent text by Peter Grego, so there was no feeling that you were only getting the star maps and star ‘biographies’, something these days much more suited to an iPad or smartphone app. Instead, the opening 30 or so pages give a very good introduction that would be valuable to ...

Ignorance: How it drives science – Stuart Firestein *****

This is a delightful little book that really gets you thinking. I stress the ‘little’ part not as a negative, but as a good thing. There is nothing worse than fat, bloated popular science books where the author feels they have to get 120,000 words to be taken seriously. This is the sort of book that can be read in a couple of hours – but you will get so much more out of it than one of those tedious doorstops. The premise underlying the book is in once sense extremely simple, yet is fundamental to an understanding of what science is and what scientists do. And it is an understanding that is totally at odds with the typical way science is portrayed both in university lectures and popular science books. As Stuart Firestein points out, what is important is not the facts, but rather the area of ignorance. The interesting part and the fundamental heart of science is not about what we know, but about what we don’t know and where we want to look next. Take this lovely quote: ‘Working ...
