Statistics: a very short introduction – David J. Hand ****

These little pocket guides are inevitably quite variable in quality. Some just pack in the facts but aren’t at all readable – they’re fine as a quick introduction for students, but they get short shrift as popular science. On the whole, though, David J. Hand’s introduction to statistics succeeds in being very readable. I think he rather over-reached himself with his stated aim of proving that statistics is ‘the most exciting of disciplines’ – but he does make it clear why statisticians find it exciting, and what a powerful and ubiquitous field it is. Very few of the sciences, soft or hard, could manage without probability and statistics.
The first half of the book, where he lays the ground, is probably the best. Once he gets into probability, with its potential to be mind-boggling fun, he rather gets bogged down, in part because he introduces rather more technicalities, and gives us less real world examples, than he should. Things get rather worse when we get onto estimation, inference and modelling, with a slightly uncomfortable parallel line describing the Bayesian approach and the classical approach.
Despite this, if you are prepared to travel a little lightly through the second half, the book is the best simple introduction to statistics I’ve come across. it doesn’t tell you how to use the various techniques and tools it mentions, but at least gives a good picture of some of the toolkit available and how the choices involved are made. With my Operational Research background, I would have liked to see the book expanding into a few OR techniques, but that’s a minor consideration. Overall, a good addition to the series.

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…
