Cracking the Particle Code of the Universe

Cracking the Particle Code of the Universe – John Moffat ****

I’ll be honest, when I saw this book I thought ‘Oh no, not another book about the hunt for the Higgs boson,’ and so put off reading it for a long while, but it fact it is far from another me-too book. If you want a good, straightforward book about the what the Higgs is and the basics of the hunt, you should head straight for Higgs by Jim Baggott, but Cracking the Particle Code is quite a different beast.

Two things make this book stand out. One is the author’s personal involvement in the field over a long period, and the other is that he is brave enough not to take the simplistic stance that we’ve found the Higgs and it’s all over, but rather to point out that things are a lot more complicated than the press releases from CERN would suggest, and that there is certainly no sense in which we can say that the standard model is complete and particle physics is signed off. In fact, as Moffat shows, it is entirely possible to generate masses using quantum field theory without the complication of a Higgs boson. He may be a minority voice – but there is certainly a lot that’s interesting about this alternative view.

The book isn’t dominated by Moffat’s own theory as he takes us through the hunt for the Higgs and the implications of the discoveries made at CERN – but equally, lacking the usual need to bolster a career that means once a theory gains enough followers it becomes gospel until there’s a major shift (Fred Hoyle likened such physicists to a flock of geese), Moffat is able to give us a uniquely balanced viewpoint.

It isn’t the easiest read – although in some ways he gives one of the best explanations of symmetry breaking (something that rarely makes sense in popular attempts to explain it as it is dependent on a mathematical world rather than anything observed), his science does crack along at a pace that requires a fair amount of application of a piece of advice I received early on while an undergraduate studying physics when my supervisor said that the only way to cope is not to panic when you don’t understand – let it flow over you, and gradually it will make sense.

If you are happy to take that approach, then I can’t recommend this book too highly. If you want an easy, hand-held read, though, look elsewhere.

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...
