Beam – Jeff Hecht ***

Beam‘s subtitle is ‘the race to make the laser’ and this was a story that was crying out for a good popular scientific history. Not only is there really interesting physics behind the laser, there was a genuine tense race, strong personalities, bizarre problems with security clearances and more to make for a gripping story.
I’ve come rather late to Beam (first published in 2005) because, frankly, the book doesn’t seem to have been very visible – and I’m afraid I can understand why. Although there are all the elements of a great story there, Jeff Hecht is probably not the right person to tell it. On the physics side, while there is a lot of detail of the precise excitation processes required for masers and lasers, there isn’t really enough background on quantum physics to give it context.
As for the story itself, the book suffers from kitchen-sink-itis. Hecht seems to feel it necessary to mention ever single tiny contribution to the research, whether or not it had a direct impact on the key players. And though the story really does get interesting when, for instance, we get onto Gordon Gould’s you’d-laugh-if-you-didn’t-cry security problems that meant he wasn’t able to read his own work, much of the storytelling gets horribly bogged down and repetitive, making it hard to follow the narrative.
The final problem is limiting the book to the race to create the first laser – it would have had a wider interest if Hecht had brought in the development of the solid state lasers we all have littering our homes in CD players and the like.
All in all, there is plenty of good stuff here, and I’m not aware of anyone else who has told the story in such detail, but you have to work quite hard to get to the nuggets.

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...

How to Keep a Plane in the Sky - Alex Davies ****

If there's one big gap in the science writing sphere, it's popular engineering (you can quibble over whether engineering is science, but where else would you put popular engineering?). Alex Davies does the field a real service with this insightful introduction to the world of test engineering. The concept is simple. If we build something and sell it, we need to test it to make sure that it won't fail in a way that's dangerous to the consumer. The most obvious example is airliners, which feature at some length, but this applies to everything from cuddly toys to hair straighteners: someone needs to predict what could go wrong and to put the product through its paces to see if it will survive under any reasonable circumstances. When Davies is telling a story of test engineering in action, the book is a delight. He opens with the way that real bears are used to test if bears can get into coolers and trash cans - and the impressive ways these animals can  circumvent human in...

On the Equality of All Things - Carlo Rovelli ****

There is a wide gulf between the worldviews of physicists and philosophers. Many physicists present a rather sweetly naive, child-like view of the world, where philosophers bring a distinctly more adult, cynical tone. This being the case, it can be a little worrying when a physicist dips a toe into the philosophical mire. Infamously, in The Grand Design , Stephen Hawking and co-author Leonard Mlodinow told us that philosophy was now dead because science could deal with anything it had previously been needed for. Thankfully, Carlo Rovelli is not trying to do away with philosophy, though it has to be said that when he veers into the topic that physicist's naivety can make it feel like the philosophising of an earnest eighteen-year-old. Take the opening paragraph, which tells us 'electrons and minds, stones and laws, judgements and galaxies do not essentially differ in nature from one another. They are notions that illuminate each other'. I almost expected a Pink Floyd soundtr...
