The Quantum Universe: everything that can happen does happen – Brian Cox & Jeff Forshaw ****

Brian Cox has picked up a lot of fans (and a few parodies) for his light and fluffy ‘here’s me standing on top of a mountain looking at the stars’ TV science shows – no doubt a fair number of them will rush out and buy his latest collaboration with Jeff Forshaw. They will be disappointed. So, I suspect, will a number of My Little Pony fans, as with its rainbow cover and glittery lettering it only needs a pink pony tail bookmark to complete the look.
The reason The Quantum Universe will disappoint is not because it is a bad book. It’s brilliant. But it is to Cox’s TV show what the Texas Chainsaw Massacre is to Toy Story. It’s a different beast altogether.
As they did with their E=mc2 book, but even more so here, Cox and Forshaw take no prisoners and are prepared to delve deep into really hard-to-grasp aspects of quantum physics. This is the kind of gritty popular science writing that makes A Brief History of Time look like easy-peasy bedtime reading – so it really isn’t going to be for everyone, but for those who can keep going through a lot of hard mental work the rewards are great too.
More than anything, I wish this book had been available when I started my undergraduate course in physics. It would have been a superb primer to get the mind into the right way of thinking to deal with quantum physics. Using Feynman’s least action/sum over paths with ‘clocks’ representing phase, the authors take us into the basics of quantum physics, effectively deriving Heisenberg’s uncertainty principle from basic logic – wonderful.
They go on to describe electron orbitals, the mechanics of electronic devices, quantum electrodynamics, virtual particles in a vacuum and more with the same mix of heavy technical arguments, a little maths (though nowhere near as much as a physics textbook) and a lot of Feynman-style diagrams and logic.
The reason I think I would have benefited so much is that this book explains much more than an (certainly my) undergraduate course does. Not explaining why quantum physics does what it does – no one can do that. But explaining the powerful logic behind the science, laying the groundwork for the undergraduate to then be able to do the fancy maths and fling Hamiltonians around and such. It is very powerful in this respect and I would urge anyone about to start a physics degree (or in the early stages of one) to read it. I would also recommend it for someone who is just really interested in physics and is prepared to put a lot of work into reading it, probably revisiting some pages several times to get what Cox and Forshaw have in mind – because they don’t ease up very often.
What I can’t do, though, is recommend this as general popular science. It isn’t the kind of excellent introduction that gives you an understanding of what’s going on in quantum theory, a view of the mysteries and a broad understanding of what the topic is about. This book is just too hard core. I’d suggest that 90% plus of popular science readers shouldn’t touch it with the proverbial barge pole. If that sounds condescending, it isn’t meant to be. Good popular science can and does have a lot more content and thought provoking meat than a typical Brian Cox TV show – but this book goes so much further still than that, inevitably limiting its audience.

How to Drive a Nuclear Reactor - Colin Tucker ****

How To Drive A Nuclear Reactor does exactly what it says on the tin. The book is a general overview of nuclear reactors. From the basic principles that make them work through to what buttons to press in what order (and of course how and why they can go wrong).Nuclear power could be a good step on the path to a greener energy future, but there is a lot of understandable fear. This book can give some idea of what an incredible feat of both science and engineering one of these machines is and, hopefully, make anyone reading it feel far more comfortable about them.The book presents information about everything, almost down to the literal nuts and bolts, giving you a near complete understanding of how a nuclear works. From putting in the fuel to getting out the power and down from the control panel to the construction material. Everything you could ever want to know is here. By the end you'll likely feel ready to walk into a control room and get started (do not try doing this, nuclear …

Being Mortal - Atul Gawande ****

I heard recently that the local geriatric ward puts a photograph of the patient in his or her prime by each bed. The aim is to help staff to treat their patients as individuals, but it makes me uneasy. Do these people only matter because of what they were, not what they are? Because once they stood proud and handsome in their uniform, or looked lovely on their wedding day?

Professor Atul Gawande has the problem surgically excised and laid out for inspection in one of his unflinching but compassionate case studies:

‘What bothered Shelley was how little curiosity the staff members seemed to have about what Lou cared about in his life and what he had been forced to forfeit... They might have called the service they provided assisted living, but no-one seemed to think it was their job to actually assist him with living – to figure out how to sustain the connection and joys that most mattered to him.’

Gawande is an eminent surgeon. As a young resident he displayed little overt emotion when hi…

Twenty Worlds - Niall Deacon *****

This is a truly entertaining and informative book, but the reason I’m giving it the full five stars has as much to do with the refreshing novelty of the author’s style as anything else. There’s novelty in the subject-matter too – the wide variety of recently discovered exoplanets orbiting other stars – but even so this is the third book on the topic that I’ve read. The first two were a lot less fun to read, and (without naming and shaming the authors) it’s worth a brief diversion to explain why.The first author was a university professor with a vast knowledge of the subject, who seemed determined to convey the entirety of that knowledge without stopping to think whether it was interesting or necessary for a general audience. The second author – another academic – took a different but equally tedious approach, with a plodding chronological account that focused as much on the dull routine of the scientists involved as on their work.Niall Deacon doesn’t make either of those mistakes. He’…
