The Graphene Revolution - Brian Clegg ****

Graphene's one of those words that gets bandied around a lot without getting more than some vague feeling of what it's all about. In the end, it's just a material, and everyone knows that books about materials don't make for very exciting reading. But the advantage Brian Clegg has here is that graphene is not just a wonder material (which it certainly is) but it also has a brilliant story attached to it.

The two Russian discoverers of graphene (sort of - more on that in a moment), working at Manchester University are, to say the least, characters. This is particularly the case with Andre Geim, who first came to fame (or infamy) when he successfully levitated live frogs using a very powerful magnet. Geim and his co-discoverer Konstantin Novoselov had the idea that you should be able to spend some time on what they called 'Friday Night Projects' (spare time activities to look at something completely different) and they succeeded remarkably with graphene.

Clegg gives us the story of the Russian duo's discovery: they used discarded bits of sticky tape that had been used to clean blocks of carbon. Graphene had already been named, as a way to describe the atom-thin layers that make up a sheet of graphite, but it was thought it wouldn't be possible to produce stable sheets of graphene, which ought to collapse under its internal forces. Geim and Novoselov set out to prove different.

Their story is hard to read without smiling, but the book isn't all about the dynamic duo. (Is it unfair to think of Novoselov as the Robin of graphene to Geim's Batman?) There's a lot on the structure of graphene, including why it's incredibly strong and pretty much the best conductor without resorting to superconductors, and also how it could be practically used. Sometimes it can seem there's a bit too much of this, as if Clegg can't resist telling us one more possibility, but we soon move onto something else.

Sometimes even those potential ways of using graphene seem to have a touch of Geim magic about them. Take, for instance, the graphene coating on a bottle that allows water to pass through but not alcohol - so anything alcoholic left in the bottle gets stronger and stronger of its own accord. This is a wonderful material, with a great story, and Clegg tells it well.

Review by Jo Reed
Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

Beyond Weird - Philip Ball *****

It would be easy to think 'Surely we don't need another book on quantum physics.' There are loads of them. Anyone should be happy with The Quantum Age on applications and the basics, Cracking Quantum Physics for an illustrated introduction or In Search of Schrödinger's Cat for classic history of science coverage. Don't be fooled, though - because in Beyond Weird, Philip Ball has done something rare in my experience until Quantum Sense and Nonsense came along. It makes an attempt not to describe quantum physics, but to explain why it is the way it is.

Historically this has rarely happened. It's true that physicists have come up with various interpretations of quantum physics, but these are designed as technical mechanisms to bridge the gap between theory and the world as we see it, rather than explanations that would make sense to the ordinary reader.

Ball does not ignore the interpretations, though he clearly isn't happy with any of them. He seems to come clo…

The AI Delusion - Gary Smith *****

This is a very important little book ('little' isn't derogatory - it's just quite short and in a small format) - it gets to the heart of the problem with applying artificial intelligence techniques to large amounts of data and thinking that somehow this will result in wisdom.

Gary Smith as an economics professor who teaches statistics, understands numbers and, despite being a self-confessed computer addict, is well aware of the limitations of computer algorithms and big data. What he makes clear here is that we forget at our peril that computers do not understand the data that they process, and as a result are very susceptible to GIGO - garbage in, garbage out. Yet we are increasingly dependent on computer-made decisions coming out of black box algorithms which mine vast quantities of data to find correlations and use these to make predictions. What's wrong with this? We don't know how the algorithms are making their predictions - and the algorithms don't kn…

Five Photons - James Geach ****

It is generally acknowledged that Stephen Hawking's A Brief History of Time is one of the most common books to be bought but not read beyond the first few pages. If you are the kind of popular science reader who found Hawking hard going, you can stop now - Five Photons is not for you. If, on the other hand, you found A Brief History of Time a piece of cake and wished you could get into more depth without resorting to heavy mathematics or a tedious textbook style, Five Photons could be just up your street.

Astrophysicist James Geach starts of fairly gently with a chapter on the nature of light that mostly sets aside quantum physics, leading up to the observation that light is our vehicle for for stripping back the history of the universe to its earliest times (or, at least, the point where the universe became transparent). From here on, the five photons of the title take us on different journeys, from the oldest surviving light of the cosmic microwave background radiation to that fr…
