The Quantum Moment - Robert P. Crease and Alfred Scharff Goldhaber ***

This is a book that is trying to be two very different things at the same time, which I suppose, given the subject, is apt. But that doesn't necessarily make it a good idea. On the one hand we find a really quite in-depth exploration of the development of quantum theory. There are some genuinely valuable insights and explanations, with significantly more use of equations than is common in popular science book, but rarely in a way that is scary. On the other hand, it churns out all the hackneyed attempts to base art on science that inevitably are either amateurish or cringemaking - plus presenting some of the more outrageous history of science ideas that emerged from the 1960s when everything had to break the mould and be provocative, however far fetched their ideas seemed.

I can imagine this was done to try to broaden the audience of the book. I can just see the marketing people thinking 'Popular science readers will love it, and so will arty types, so we'll sell lots more copies.' In practice, I think the reverse will happen, because a fair number of popular science enthusiasts will be put off by the wishy-washy science-as-metaphor stuff, while the arts types will find the hard core popular science tedious.

 I'm not quite sure how in touch the academic authors are with the real world either. At one point we are told that Planck's equation E=hν is 'one of the few equations recognizable by the public.' Really? They've clearly been on campus for too long and need to get out more.

There is so much good material in the science parts that it's a real shame that the reader has to plough through pages of the hand waving to get to it. We are told at one point, with enthusiasm and no sense of criticism, about the work of Valerie Laws, who in 2002 spray painted words onto sheep, enabling the flock to spell out randomly(ish) generated phrases. Apparently a spokesperson for Northern Arts, which funded this venture, said the result was 'an exciting fusion of poetry and quantum physics.' And the artist commented 'I decided to explore randomness and some of the principles of quantum mechanics, through poetry, using the medium of sheep.' You couldn't parody this as a worse example of old-fashioned flaky linking of science and art. It's a ready-made Monty Python sketch. This had nothing to do with quantum physics.

There is plenty of great material in here if you want to expand a basic popular science understanding of quantum physics with a bit more depth, but you will have to wade through a lot of unnecessary material to get to it. Mostly the content seems spot on, though I was slightly concerned about a certain flexibility in the history of science presented when we hear, for instance, that returning from the 1911 Solvay conference 'British scientist Ernest Rutherford brought word back to England, where he shared his excitement with an entranced young Danish visitor, Niels Bohr.' Apart from Rutherford being a New Zealander, Bohr didn't meet Rutherford until the end of 1911 and I've never seen any suggestion that Rutherford was the first to bring the early quantum theory to Bohr's attention. So, approach with caution - but if you are tolerant (possibly more tolerant than me), you might enjoy it.

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…

Jim Baggott - Four Way Interview

Jim Baggott is a freelance science writer. He trained as a scientist, completing a doctorate in physical chemistry at Oxford in the early 80s, before embarking on post-doctoral research studies at Oxford and at Stanford University in California. He gave up a tenured lectureship at the University of Reading after five years in order to gain experience in the commercial world. He worked for Shell International Petroleum for 11 years before leaving to establish his own business consultancy and training practice. He writes about science, science history and philosophy in what spare time he can find. His books include Atomic: The First War of Physics and the Secret History of the Atom Bomb (2009), Higgs: The Invention and Discovery of the ‘God Particle’ (2012), Mass: The Quest to Understand Matter from Greek Atoms to Quantum Fields (2017), and, most recently, Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe (2018).

Quantum Space: Jim Baggott *****

There's no doubt that Jim Baggott is one of the best popular science writers currently active. He specialises in taking really difficult topics and giving a more in-depth look at them than most of his peers. The majority of the time he achieves with a fluid writing style that remains easily readable, though inevitably there are some aspects that are difficult for the readers to get their heads around - and this is certainly true of his latest title Quantum Space, which takes on loop quantum gravity.

As Baggott points out, you could easily think that string theory was the only game in town when it comes to the ultimate challenge in physics, finding a way to unify the currently incompatible general theory of relativity and quantum theory. Between them, these two behemoths of twentieth century physics underlie the vast bulk of physics very well - but they simply can't be put together. String theory (and its big brother M-theory, which as Baggott points out, is not actually a the…
