How to Save the World with Salad Dressing – Thomas Byrne & Tom Cassidy ***

I first read this book as a manuscript to provide a puff for the cover. As my comment says ‘Brilliant! I couldn’t stop reading,’ it might seem hard to reconcile with three stars. In a sense both are true.
The book uses a frankly lame storyline to link a series of science-based problems where you have the opportunity to think through a problem (supposedly faced by the hero in the storyline) and then check with the answer, learning some science painlessly along the way. It starts with a brief science guide (well, mechanics really), then plunges you into the problems, where you take on Erik van Basten ‘the world’s foremost evil genius’ and ‘creator of the world’s most powerful criminal empire.’ Ho hum. The trouble with this kind of fictional approach is it’s fairly cheesy for children – if the book’s for adults, which I think it is, then it doesn’t work for me.
What is good, though, is the series of problems. These were the reason ‘I couldn’t stop reading’ – it’s very tempting, having worked through one, to go onto the next and the next. To give an example of the sort of problem (and the ‘humour’), at one point our hero is standing on a set of very sensitive scales and expels a ‘methane fart’ – we are asked to work out what happens to Ethan’s mass, his weight and the scale reading.
We then have to flip to the back to read the answer. I found this highly tedious with a total of 26 problems to deal with. Given you have to read the answer before moving on, it would have been so much easier if each answer followed the appropriate problem. Generally speaking the science is pretty good. The specific problem I mention they get wrong, but I pointed this out before publication and they have put in an explanatory note, though sadly the explanation doesn’t actually fix the error – but all the rest is fine.
There still might seem to be a bit of a variance between that ‘Brilliant!’ and my assessment. That is because what I actually said was Building a book around ingenious science challenges for the reader to solve is brilliant. I couldn’t stop reading – after each problem I had to move onto the next. Best of all it made me really think about basic physical principles, but never felt like a dull science lecture. All of which I still hold to be true. But sadly, the way the book delivers an excellent concept could be done better.

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…
