Collider – Paul Halpern ****

The Large Hadron Collider at CERN is set to give us deep insights into the nature of matter and the origins of the universe. It could provide evidence of extra dimensions, and give us an idea of whether string theorists are on the right track. This is fascinating stuff, and it is what Paul Halpern aims to explain in Collider, after first giving us a history of high energy physics and particle accelerators.
I wasn’t very optimistic about the book at first. It jumps straight into the Higgs mechanism and spontaneous symmetry breaking without explaining these concepts in much detail for the layperson. I was a little worried the book was going to turn out to be over-technical, and only fully understandable to those with a physics degree. Luckily, this wasn’t the case at all, and when the book gets on to talking about the LHC in detail, and how it works and what it will be looking for, the concepts are fleshed out clearly and simply. In fact, Halpern has a knack of explaining tricky ideas well for the general reader in the minimum of words. Where something isn’t entirely clear, the book still leaves the reader with a fairly good grasp of what’s being discussed.
Overall, the science of the LHC is covered quite well, and there’s an entertaining section on ‘Citizens Against the Large Hadron Collider’, a group concerned about world destroying scenarios at CERN, in which Halpern explains why there’s nothing to worry about. The most readable parts of the book, however, are in the middle, where it covers earlier high energy research and the people involved.
The best chapter is on the first particle accelerators, and contains a significant amount of biographical information about Ernest Rutherford, Ernest Walton, John Cockcroft, Ernest Lawrence, and Rolf Wideroe, someone I knew little about beforehand. Wideroe was a Norwegian engineer whose research provided a lot of the impetus for Rutherford’s team at the Canvendish Laboratory in Cambridge to build the linear accelerator they used to split the nucleus of lithium. He also inspired Lawrence to build the first cyclotron, a circular accelerator. Another highlight, which again shows the book is rather better on history and surrounding issues, is the account of what happened to the Superconducting Super Collider, intended for Texas but eventually never completed. The section contains a number of lessons to be borne in mind when future, similar projects are planned.
There’s one small point. The book costs £19.00 in the shops, which I think is a bit much; £15.00 would be more appropriate. Overall, though, this is an interesting book, great for anyone wanting to know what could happen at the LHC over the coming years and the context in which the project has been developed. This is definitely a solid four star book, and I got a lot from it.

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...
