A Briefer History of Time – Stephen Hawking (with Leonard Mlodinow) ****

When the original Brief History of Time came out in 1988 it caused a sensation. It was the book to have on your shelves (though there was a certain tendency to admit to not having read it). And it was, justifiably, a great popular science book – yes it got hard towards the end, but it was well worth the effort.
The idea of Briefer History is to repeat the success of the original, but to do it in a more painless way. It’s a mixed success.
In part it delivers. It’s a sprightly canter through modern cosmology and the associated science, and it does it largely with flair and in a highly approachable fashion. After telling us the goal of science is a unified theory of everything (rather a doubtful proposition, but we’ll overlook that), we take a rapid trip from Newton through relativity to the expanding universe, the big bang, black holes, wormholes and all the traditional menagerie of the modern cosmologist. Because the book comes 17 years after its predecessor there’s a whole lot of new material to encompass, which is great, though it does mean there’s not quite the opportunity there might have been to go through the fundamentals from the first book but explain them in a more gentle fashion.
So the good news is it’s an effective look at the whole cosmological picture today – quantum gravity, strings and all (though dark matter/dark energy are rather skimmed over), it has the very positive endorsement of coming from a scientific superstar (the man appeared on Star Trek TNG – what can you say?), and it’s glossy enough to impress the most selective coffee table book buyer. And that’s enough to gain it four stars. But…
But there are aspects of the desperate attempt to become reader-friendly that get in the way in practice. It’s just a bit too glossy (even literally – the pages are shiny picture book pages, which are a little hard on the eye after a while). Leonard Mlodinow was presumably thrown in as editor to reign back any tendency Hawking might have to go off on riffs most of the readers couldn’t follow, but he has also homogenised the quite personal approach that was one of the strengths of Hawking’s original book. And, for a simple guide, there’s the classic error Feynman was always railing against of using labels as if they explain something – so we hear about electromagnetic fields, for instance, with no attempt to conquer the (admittedly difficult) problem of explaining what a field is.
Perhaps worst of the negative side are the illustrations – they smack of an out of control art director. The illustration, for instance, for the idea that people thought the world was a sphere because ships on the horizon appear masts first, shows a ship on the horizon… all in view. It’s a flat earth picture.
Incidentally, Hawking & Mlodinow perpetuate the myth that historically “it was common to find people who thought the earth was flat”. In fact, educated people have known it was a sphere continuously since the Ancient Greeks – the myth of medieval flat earth belief was devised in the 19th century as anti-Christian propaganda. Of course most people through history haven’t had any opinion on the matter, they’ve been to busy staying alive.
Other pictures are less easy to understand than a simple diagram would have been because of all the extra unnecessary detail – a good example is a “ping pong balls on a train” illustration where it’s very difficult to see what the point is. One diagram even verges on the offensive, in a demonstration of the increased attraction from a doubly heavy body by showing a man (Hawking as it happens) “attracted” to a pair of Marilyn Monroes.
This isn’t by any means a bad book. We’ve awarded it four stars and put it in our “near best” category because it will reach more people than arguably better books like Simon Singh’s Big Bang – even so, it’s a disappointment partly because of the übergloss, and partly because Hawking’s personality doesn’t come through as well as it does in the original.

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…
