Quantum – Manjit Kumar ***

The first thing that strikes you about this book it’s big. It’s a chunky tome. It looks suspiciously like the sort of book that assumes you’ve written a ‘big’ book if you have written a long one, and sadly the contents don’t do anything to counter this opinion. It goes on too long, it’s often dull and I couldn’t really find any new ground being covered here – it has all been done before, better and more readably.
For example, the early chapters on Planck and Einstein feel very samey with all the other material I’ve read on them (though it’s particularly plodding here). The trouble is, you feel you have to put all this stuff in, but there’s no doubt that it’s going over old ground with a will. Things do live up a little when we get onto Bohr, who has relatively little biographical information written about him. However, even here things aren’t all sweetness and light. The problem with this section is the author’s poor structuring. We keep diving back and forth in time. Part way through Bohr we jump back to JJ Thomson’s mini biography, before we can really get any progress we then jump out again for Rutherford’s biography, part way through which (nest jumps!) we pop out for Roentgen’s biography and so on.
Later on, when we get onto the massed brigade of young quantum turks, there are just too many being thrown at us, the biographies get very dull and samey. It’s not so much unputdownable at this point as unpickupable.
All the way through it’s a touch too technical for the general reader. There are unnecessary formulae and units are rarely explained. The science is often it bit too close to what I remember from first year physics lectures at university.
All in all, this would make a good textbook to give some context to those studying quantum physics, but it’s a poor attempt at a popular science book on the topic. Take a look at Marcus Chown’s Quantum Theory Cannot Hurt You for a much better general introduction.

The AI Delusion - Gary Smith *****

This is a very important little book ('little' isn't derogatory - it's just quite short and in a small format) - it gets to the heart of the problem with applying artificial intelligence techniques to large amounts of data and thinking that somehow this will result in wisdom.

Gary Smith as an economics professor who teaches statistics, understands numbers and, despite being a self-confessed computer addict, is well aware of the limitations of computer algorithms and big data. What he makes clear here is that we forget at our peril that computers do not understand the data that they process, and as a result are very susceptible to GIGO - garbage in, garbage out. Yet we are increasingly dependent on computer-made decisions coming out of black box algorithms which mine vast quantities of data to find correlations and use these to make predictions. What's wrong with this? We don't know how the algorithms are making their predictions - and the algorithms don't kn…

Five Photons - James Geach ****

It is generally acknowledged that Stephen Hawking's A Brief History of Time is one of the most common books to be bought but not read beyond the first few pages. If you are the kind of popular science reader who found Hawking hard going, you can stop now - Five Photons is not for you. If, on the other hand, you found A Brief History of Time a piece of cake and wished you could get into more depth without resorting to heavy mathematics or a tedious textbook style, Five Photons could be just up your street.

Astrophysicist James Geach starts of fairly gently with a chapter on the nature of light that mostly sets aside quantum physics, leading up to the observation that light is our vehicle for for stripping back the history of the universe to its earliest times (or, at least, the point where the universe became transparent). From here on, the five photons of the title take us on different journeys, from the oldest surviving light of the cosmic microwave background radiation to that fr…

Mercury - William Sheehan ****

Driving to work one morning several years ago, I spotted a tiny white dot close to the rising sun. ‘That’s Venus,’ I said to myself. Almost immediately I saw another, much brighter dot a few degrees away. ‘No, that’s Venus – the first one must be, um ... Mercury.’ Even with a lifelong interest in astronomy, I always manage to forget Mercury.

With eight planets in the Solar System, one of them has to be the least interesting – and Mercury got the short straw. That’s a relative statement, though, and a diligent author could still dig up enough fascinating facts about that tiny dot by the Sun to fill a short book. William Sheehan has done a brilliant job of doing just that.

One of the reasons Mercury is so easy to forget is that it’s almost impossible to get a good view of it from Earth. Even after the invention of the telescope, which turned planets like Mars and Jupiter into explorable worlds, Mercury remained a mystery – and the subject of some pretty wild speculations. In 1686, for exa…
