Atoms Under the Floorboards - Chris Woodford ****

I am very fond of the 'take something everyday and use it to explore science' genre - I did exactly that with my book The Universe Inside You, and I'm delighted to say that in Atoms Under the Floorboards - the surprising science hidden in your home, Chris Woodford takes the same kind of approach, yet come up with a totally different and highly engaging book.

The introduction was a little worrying, as it tries a bit too hard to be friendly in a way that feels at times like a kid's book ('surprising scientific explanations behind all kinds of everyday things, from gurgling drains and squeaky floorboards to rubbery custard and shiny shoes') and at others like the over-enthusiastic introduction to the Hitch Hiker's Guide to the Galaxy. Like that remarkable tome, it settles down after a bit, although the text throughout has a kind of breathless enthusiasm that feels like it ought to be read aloud by the actor in the Cillit Bang commercial. (If you aren't familiar with the oeuvre, try this example.)

Mostly the result is phenomenal. I love the way that Woodford thinks about things we don't normally consider, like why houses don't fall down, and goes off on a riff that compares the forces from the weight of an apple (conveniently about 1 newton), through the bite of an alligator to the Space Shuttle blast-off. He manages to make very ordinary, basic stuff like simple machines (levers, wedges, wheels and the like) and turns them into things that we look at differently and understand in more depth while still genuinely enjoying what's being covered.

The only part I'd say where things get a bit sticky are the sections where he's covering material science, which frankly got just the teeniest bit dull, although even here, thinking about, for instance, the nature of glue was quite an eye-opener. If I'm going to be picky - and you have to, really, in the communication of science - the mega-breezy approach does lead to one or two pretty well incorrect statements. Einstein came up with a baffling new theory called relativity - no he didn't (that was Galileo). Or Rutherford split the atom in his gold foil experiment - no he didn't.

Even so, there is plenty to enjoy and plenty of 'I didn't know that' moments, whether you are reading about the science of slipping or the mechanism of an LED lamp. We end up with the topic of clothing, from how different materials keep you warm and/or dry (though again materials science is the least interesting aspect of the content), why jeans wear out at the knees (contrasted with a pulley), and the science of shoes, which is fine, but just stops - I'd have liked a bit of a wind-down at the end.

One final plus point - in the 'Further Reading' in the back, rather than showing off, as some authors do, by listing eminent but unreadable tomes, Woodford lists some excellent suggestions, including several that have received five stars here.

Altogether a fun, light hearted science book that you could give to a teenager, or the sort of person who doesn't really read popular science but would like to find out a bit more about the scientific world around them - and I think they'll have a good time.

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 …

The Bastard Legion (SF) - Gavin Smith *****

Science fiction has a long tradition of 'military in space' themes - and usually these books are uninspiring at best and verging on fascist at worst. From a serious SF viewpoint, it seemed that Joe Haldeman's magnificent The Forever War made the likes of Starship Troopers a mocked thing of the past, but sadly Hollywood seems to have rebooted the concept and we now see a lot of military SF on the shelves.

The bad news is that The Bastard Legion could not be classified as anything else - but the good news is that, just as Buffy the Vampire Slayer subverted the vampire genre, The Bastard Legion has so many twists on a straightforward 'marines in space' title that it does a brilliant job of subversion too.

The basic scenario is instantly different. Miska is heading up a mercenary legion, except they're all hardened criminals on a stolen prison ship, taking part because she has stolen the ship and fitted them all with explosive collars. Oh, and helping her train her &…

Euler's Pioneering Equation - Robin Wilson ***

The concept of a 'beautiful equation' is a mystery to many, but it seems to combine a piece of mathematics that expresses something sophisticated in relatively few terms and something that looks satisfying. The equation that has proved standout amongst mathematicians, as by far the most beautiful (and is only placed second to Maxwell's equation amongst physicists) is Euler's remarkable eiπ+1 = 0. What seems remarkable to me about this is that it just seems bizarre that this combination of things produces such a neat result. (Incidentally, as far as I can see, the only reason for the 'pioneering' in the title was to enable the fancy graphic on the cover of the book.)

Getting popular maths books right is incredibly difficult. When I started reading this book, I really thought that Robin Wilson had cracked it. After an introduction, he gives us a chapter on each of the elements of the equation (except the plus and equals signs), from the more basic aspects like 1 a…
