Unknown Quantity – John Derbyshire ***

There is something rather fascinating about the little quotes you see on a the cover of a book. Sometimes they are intriguing, sometimes banal. In this case of this particular book, I had to wonder if someone writing for New Scientist, who commented “even algebraphobes will struggle to fault” was reading the same book. To be fair, “struggle to fault” is such a suspiciously ugly phrase that it’s hard not to suspect that there was more to that sentence in the original form than meets the eye. Whatever – as it stands it is very misleading.
To be fair, John Derbyshire does intertwine the mathematical bits of this history of algebra with a bit of context, telling us about the people involved, and those bits work rather well, but the fact remains there is no way you can describe this as a popular maths book. The suspicions are immediately raised by the way the book is divided up into numbered sections. There’s nothing like seeing §3.2 to bring all the joy of reading a textbook flooding back. What joy? Well, no, there isn’t any, is there? Before long, however much he Derbyshire dresses this up by telling us that Cardano (say) was “‘a piece of work’ as we might say now”, nine readers out of ten will be either struggling or bored rigid. This simply isn’t the way to get maths across to a popular audience. Maybe he should read a touch of Hawking to get the idea that you can be quite erudite without leaving your reader totally baffled.
In principle I hope I could have understood the maths – in practice, I didn’t want to. I have only ever given up three books part way through. One of these was a novel that everyone tells me is a classic and wonderful, but I found childish and boring (Catch 22), so maybe it’s me. On the other hand it could be the book.
If you are a mathematician and are interested in algebra, this is a great book to get some historical context, something sadly lacking from much university teaching. If you’re not – I really wouldn’t bother. For a much more approachable history of algebra (with group theory and symmetry thrown in) see The Equation that Couldn’t be Solved.

Mathematics with Love – Mary Stopes-Roe *****

Admittedly it’s early days (this review is written in January), but this, for me, is the surprise hit of the year so far! I approached this book with trepidation, but found it absolutely delightful. It is described on the cover as the “courtship correspondence of Barnes Wallis, inventor of the bouncing bomb”, and contains a series of letters between Wallis and his cousin and eventual wife Molly Bloxham, along with some useful annotation by their daughter, Mary. The courtship itself is not without difficulties, as Wallis was 18 years older than the 17-year-old Molly at the start of the correspondence, and her father, not surprisingly, wasn’t too pleased about the interest of such an elderly suitor, but that isn’t the only reason the letters are interesting – it’s also because of maths, and Wallis’s position in the UK as the engineering hero of the Second World War. (Incidentally, it seemed very strange to see letters addressed to “Barnes” – I had always assumed Barnes Wallis was a ...

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...

On Time - Jim Al-Khalili *****

By a small margin Jim Al-Khalili's The World According to Physics is my favourite of his books, both because the 'three pillars' concept at its heart works so well - but also because it's short. On Time is somewhat heavier, but thankfully not a wrist-buster. It might seem at first sight odd that a book on a subset of physics is considerably longer than one covering the whole thing, but time is one of those subjects that inevitably involves considerable complexities and needs depth. As Al-Khalili establishes, it's hard to think of any other scientific concept where our perception of it - what he refers to as manifest time or psychological time - is so different from the view from physics. Some physicists go so far as to suggest that time doesn't exist at all. In the book, Al-Khalili sets out (to my mind quite successfully) both to explain why they think this is the case, but also why it's not the best interpretation of time. I'd certainly note that I...
