A Grand and Bold Thing – Ann Finkbeiner *****

Over the summer I tend to cut back on reading popular science so I can come back to the reviewing refreshed – and what a refreshing book to come back with. Ann Finkbeiner’s account of the making of the Sloan Digital Sky Survey was wonderful – without doubt the best popular science book I’ve read so far in 2010.
It tells the story of the establishment of a scientific project – the mapping of a whole large section of sky in detail, providing digital information that would allow for pretty pictures like Google Sky, but more of interest to the scientists involved would enable comparison of galaxies, quasars, stars and more across a swathe of sky using digital data that including vast amounts of spectrographic analysis, images using different coloured filters and more. In effect, with the results of the survey – freely available to anyone – it’s possible for astronomers to work statistically, to make the sort of comparisons that ‘real’ scientists can do with repeated experiments, but has not been possible for astronomy before. As well as providing information that was expected, the Sloan was soon also making revelations that were never dreamed of when the survey was conceived. An astronomer could spend her entire career mining knowledge from the Sloan data without ever going near a telescope. Purists may wince at this – but in terms of our knowledge of the universe it is amazing.
However, as Finkbeiner shows us with excellent portraits of the people and processes involved, this huge success of a scientific project was no easy ride. There were difficult personalities and technical disasters. Mirrors cracked, one of the two telescopes proved totally unsuitable for the job (luckily they found a replacement in an existing telescope that wasn’t doing much as it was in a city and practically useless). To the outside observer who has any experience of project management is, frankly amateurism when it comes to getting the project together. There were lots of technical experts who knew exactly what they wanted – but no one making sure things happened at the right place in the right order to succeed.
It’s a dramatic story of a project that could easily have been cancelled, of remarkable feats of technology and ingenuity – and of the drive that makes people want to observe the universe. Finkbeiner really puts us in the heart of it. We live the experience with those astronomers and technicians. It’s a beautifully crafted book from an author who really knows how to tell a story.
Just three small gripes. Finkbeiner tends to switch between the past and present tense too often, sometimes mid-paragraph, and this can read a little oddly. The last couple of chapters seem a little rushed. They’ve done what they set out to do, now we’ll wrap it up – it feels slightly anti-climactic. And there are no pictures – none at all. I know what a pain it is to get illustrations together (and the poor author usually has to pay for them), but it seemed strange in a book so focussed on people and on producing images of the sky that we didn’t have photos of those people, the telescope or any of the output of the survey.
But these are minor niggles indeed. This is a brilliant book that captures the reality of getting a scientific project together. It’s hugely readable and highly recommended.

The Quantum Menagerie - James Stone ***

This is a well-structured introduction to the mathematical basics of quantum mechanics, highly recommended for the right readers. Stone wisely, in terms of introducing the physics, avoids a purely chronological approach, instead aiming to fit together a picture in the way that makes it easiest for readers to get their heads around, building mathematically through the book. Stone does a good, solid job of this. In the book's preface, he tells us 'Books on quantum mechanics come in two basic formats: popular science books and textbooks. By contrast, this book represents a middle way between these formats, combining the informal approach of popular science books with the mathematical rigour of introductory textbooks... The material in this book should be accessible to anyone with an understanding of basic calculus.' The approach and the resultant impact on its audience is interesting. Providing something in-between popular science and a textbook is an interesting concept, but

Fundamentals - Frank Wilczek ****

In keeping with the trend of having seven this or ten that (Carlo Rovelli has a lot to answer for), physicist Frank Wilzek sets out to give us 'ten keys to reality'. As Wilczek explains in his introduction, the aim is to explore two themes: abundance and seeing things differently, with a childlike curiosity and lack of preconceptions. The author also points out that he aims to offer an alternative to religious fundamentalism. As he notes, many of his scientific heroes were devout Christians, and he 'aims to transcend specific dogmas, whether religious or anti-religious'. In essence there are two things going on in this book. On the one hand, each of the ten main sections covers a fairly straightforward aspect of physics and cosmology, though not from the viewpoint of a physical theory so much as context such as space, time, natural laws and so on - in this, it will be familiar ground to anyone who has read a popular science physics primer. But the aspect that lifts Wilc

A Song for Molly - Jeremy Bernstein ***

This is quite probably the strangest popular science/maths book I have ever read. There have been a good few attempts to combine science writing with fiction, as A Song for Molly does. It's a great idea, but from the results I have seen so far, extremely difficult to do well. What Jeremy Bernstein does is different from anything I've seen before, and in some aspects works very well. Let's start with what I love about this book. Every now and then I have lunch with the varied collection of individuals who once made up the Lancaster University Christmas University Challenge team. We're a very different bunch, and the group includes brilliant raconteurs. The lunches are a delight, in part because of the way the conversation ranges far and wide. There is a similar joy in Bernstein's range of interests as his book skips from the ideas of Wittgenstein to the attempts to decipher Linear A/B, from Cantor's ideas on infinity to game theory. It really feels like sitting
