From Cosmos to Chaos – Peter Coles ***

There are times when I think there’s a ‘Shoot Ourselves in the Foot’ department at Oxford University Press. It might seem the only explanation for the frequency with which they produce popular science books that are brilliant concepts but terribly executed. In fact, I think the reason is down to their choice of authors. They seem to choose authors on their academic background, rather than their ability to communicate. So what the reader often ends up with is a book that is replete with promise, but that fails to deliver in catastrophic fashion.
This book is perhaps the most dramatic example of this I have ever seen. The subject is fascinating, both in its intellectually engaging nature and its applicability. Yet the contents are a disaster for the popular science reader. Anyone attempting to read it who isn’t at least a student on a maths or physics degree course is doomed to frustration. It simply doesn’t explain enough, and what it does put across makes much too heavy use of maths.
This is hair-tearingly frustrating because the topic is wonderful. In a slim volume of 211 smallish pages, Peter Coles introduces probability theory, the importance of statistics to science and everyday life, the difference between a Bayesian and frequentist approach to statistics and observes how Bayesian statistics could be of great value in getting a better understanding of many areas. And he throws in quite a lot of cosmology, explaining the importance of statistics in the field. Any one of these would make engaging reading in its own right – together it’s a tour-de-force. In content terms this is easily a five star book.
Yet time after time the reader struggles to understand just what is going on. This isn’t helped by an unusually high number of misprints (often missing words rendering a sentence meaningless), but primarily it’s because the language is impenetrable and Coles does not shy away from scattering the page with integral calculus, instantly turning off 90% of the audience. I’ve always felt the famous advice given to Stephen Hawking that each use of an equation halves the audience was exaggerated – and it very much depends how you use those equations – but here they are much too frequent and too complex. Coles also sticks to the representations used in the ‘real’ equations where often these could be simplified by using terms that are more meaningful.
Altogether the resultant effect is huge frustration. For those who can get the point of this book – pretty well any working scientist with a reasonable grasp of maths, for example – it’s highly recommended. And I know scientists are a significant part of the audience for popular science. But a wider audience deserves to access what’s in this book.
I’d like to make a proposition to OUP. How about doing two versions of books like this, the original and one re-written for the general reader by someone who knows how to communicate science outside the scientific community. (I’d even volunteer to write the general reader versions!) Now that really would be something to celebrate. But for the moment there’s more chaos than cosmos in this book.

The Feed (SF) - Nick Clark Windo ****

Ever since The War of the Worlds, the post-apocalyptic disaster novel has been a firm fixture in the Science Fiction universe. What's more, such books are often among the few SF titles that are shown any interest by the literati, probably because many future disaster novels feature very little science. With a few exceptions, though (I'm thinking, for instance, The Chrysalids) they can make for pretty miserable reading unless you enjoy a diet of page after page of literary agonising.

The Feed is a real mixture. Large chunks of it are exactly that - page after page of self-examining misery with an occasional bit of action thrown in. But, there are parts where the writing really comes alive and shows its quality. This happens when we get the references back to pre-disaster, when we discover the Feed, which takes The Circle's premise to a whole new level with a mega-connected society where all human interaction is through directly-wired connections… until the whole thing fails …

Everything You Know About Space Is Wrong - Matt Brown ****

What we have here is a feast of assertions some people make about space that are satisfyingly incorrect, with pithy, entertaining explanations of what the true picture is. Matt Brown admits in his introduction that a lot of these incorrect facts are nitpicking - more on that in a moment - but it doesn't stop them being delightful. I particularly enjoyed the ones about animals in space and about the Moon.

Along the way, we take in space exploration, the Earth's place in space, the Moon, the solar system, the universe and a collection of random oddities, such as the fact that Mozart didn't write Twinkle, Twinkle Little Star. Sometimes the wrongness comes from a frequent misunderstanding. So, for example, Brown corrects the idea that Copernicus was the first to say that the Earth moves around the Sun. Sometimes there's some very careful wording. This is used when Brown challenges the idea that the Russian dog Laika was the first animal in space. What we discover is that, i…

Dark Matter and the Dinosaurs - Lisa Randall ****

I did my PhD in galactic dynamics - which is an awkward subject when people want to know what its relevance to the 'real world' is. So I was excited when Clube and Napier's book The Cosmic Serpent came out, around the same time, because it provided me with a ready-made answer. It argued that the comets which occasionally crash into Earth with disastrous results - such as the extinction of the dinosaurs - are perturbed from their normal orbits by interactions with the large-scale structure of the galaxy.

I was reminded of this idea a few years ago when there was a flurry of media interest in Lisa Randall's "dark matter and the dinosaurs" conjecture. I was sufficiently enthusiastic about it to write an article on the subject for Fortean Times - though my enthusiasm didn't quite extend to purchasing her hardback book at the time. However, now that it's out in paperback I've remedied the situation - and I'm glad I did.

Dark matter is believed to exi…
