Having read a large number of personal statements from physics applicants to Dundee this year, it is clear that, much as it was for me, particle physics and the quest for the fundamental understanding of how the Universe works is something that really gets physics students fired up. For me this was undoubtedly true, and I suspect that my knowledge of the particle zoo was probably rather better as a teenager than it is now. The quest for the Higgs Boson has undoubtedly captured the public imagination over the past few years, and I very much hope it is helping to inspire the next generation of physics students.
But I have small confession – these days it all leaves me a bit cold (although oddly, I think neutrino oscillations are pretty cool). I am clearly a bad physicist, as isn’t this stuff supposed to inspire me too? As it happens I seek that inspiration, still, in the form of popular science books (and blogs), as the technical detail of the search for the Higgs and other particle physics is a long way from my comfort zone, but even though Ian Sample’s and Sean Carroll’s books about the search for the Higgs sit upon my bookshelf, every time I pull them down I find an excuse to read something else. But when I was given Jon Butterworth’s ‘Smashing Physics‘ for Father’s Day I figured that it was time to bite the bullet and get stuck in.
I think one of the key things that Smashing Physics has going for it is that is a personalised tale – full of asides – and the fact that author has a direct connection with the Higgs search (through the ATLAS experiment) makes everything very much more immediate. It also has mini-treatise on the need and justification for basic scientific research, and reads a little like a manifesto for particle physics at times. In this sense it is very much a reflection of the very positive message than the particle physics community has been able to present in recent years, and the effects of this are being felt, for example, in the new Scottish school Physics curriculum. I’m not completely sold by this argument [particle physics must be funded at all costs] – one counterpoint is that it’s really expensive to do these experiments and one could do lots of other interesting physics with the money. While politicians might prefer to see work funded that is more applied, that has, in the language of our times, more impact, my own view is that there is an high intrinsic value in doing basic research, but of course there is plenty of other fundamental research that one could do, other than look for Higgs Bosons, in areas such as condensed matter physics, photonics, quantum optics etc. I get the sense the particle physics community forgets this from time to time. I enjoyed these asides however as they give a really good overview of how science works, why it is important and the benefits it can bring both intellectually and at tangents to what you are actually doing.
The book itself is a compelling read, covers the ground in a straightforward way and has useful glossary sections to cover the background info you need to understand the more technical parts. It does, in my mind, make a reasonable assumption that you have some technical knowledge of the subject. As an example, as far as I can see, despite significant discussion of things like the electroweak symmetry breaking, there is no definition of what the weak force actually is – certainly not from the index entries. There are various other bits of technical jargon that seem to pop up from time to time with no real explanation, so I suspect an interested person having no physics knowledge at all might struggle at times, but perhaps an interested teenager who has read some other popular books in this area could get something from it. I have no huge issue with this technical level as I find it hard to trudge through books which start at the basics, and read like every other popular science book on ‘modern’ physics areas. Diving in at the deep(ish) end can be rewarding.
So I’d certainly recommend the book, and it might even make me get down some of these other Higgs search texts I’ve been shying away from. Smashing.
