The Quantum Age – Brian Clegg *****


Updated to include paperback
There are a lot of popular science books about quantum physics, and to be honest it seemed likely this was going to be a ‘me too’, more of the same, kind of book, whichmade it a pleasant surprise.
It’s not that Brian Clegg doesn’t explain the basics of quantum theory – he does this very well – but what set this book apart for me was the way that it focussed on the applications of quantum physics – the things that have changed our lives (and made my work in computer science possible) and that Clegg labels as the ‘Quantum Age’ much as we had the Stone Age or the Steam Age.
Electronics provides the most obvious of these applications, but we also visit the quantum world of the very cold where superconductivity and superfluids come into existence – and even explore the relevance of quantum physics to biology. This is all done in a very readable, storytelling fashion. This was particularly strong when bringing in key characters, like the remarkable Heike Kamerlingh Onnes (you’d have to be good with a name like that) responsible for early discoveries in the world of super cold, and the riveting story of the development of the laser which features everything from serendipity to the weird fallout of the US fear of communists in the 1950s that meant a leading scientist was not allowed to read his own notes as he didn’t have clearance to do so.
If there’s a fault, I could have done with rather more on some of the  topics, but overall the combination of the quantum physics and the applications makes the whole subject much more approachable than simply taking on the science. As one of my favourite authors, John Gribbin, says on the back ‘Brian Clegg does a superb job of explaining complicated scientific concepts in an easily understood language. The Quantum Age is his best book yet, because the concepts he explains are central to our everyday lives in the 21st century even though most people think they are incomprehensible and abstruse.’

Review by Peet Morris
Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

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…
