The Disappearing Spoon – Sam Kean *****

Winning the honour of being the first five star book of 2011, Sam Kean’s The Disappearing Spoon is an entertaining romp through the chemical elements. Rather than take the kind of rigid, structured walk through the periodic table that might seem the natural approach, Kean lumps together rather random collections of elements, linked only by the wonderful rambling tales of their discovery, use and general oddity.

In case you were wondering, the ‘disappearing spoon’ refers to gallium, which has a melting point of around 30 degrees Celsius. Despite being a metal with a fair resemblance to aluminium, it will melt in your hands (unlike certain sweets). So make a spoon out of gallium, give it to someone to stir their tea, then sit back and chortle as they wonder where the spoon went. Ah, how we laughed.

This book is entirely entertaining – it’s a real page turner, and there’s very little not to like about the combination of a string of QI like fascinating facts with a whole slew of engaging stories. Of course we get Mendeleev (and a couple of his counterparts), but mostly its about the elements themselves.

If I have to quibble, Kean is not at his best explaining atomic orbits and bonding – I thought that could have been done better – and sometimes the casual phrasing seems a trifle overdone. So for instance we read ‘… had sponsored porcelain research but had succeeded in producing only C-minus knockoffs.’ This feels a bit forced to me. Similarly we hear that Henry Moseley was ‘a pill, stiff and stuffy.’ I’ve no idea what being ‘a pill’ means (unless he was small, white and swallowable), and this sort of one-line characterisation seems more appropriate to 1066 and All That than it is to a modern popular science book. However, such lapses are relatively uncommon. (I ought to also mention that he claims calling a person who does calculations ‘a computer’ was a neologism in the Manhattan Project – if he’d bothered to check, the term has been used since the 17th century.)

Overall this was a book that was a delight to read, taking a very predictable subject and approaching it in an entertaining, original and informative way. If you want to read a serious history of the periodic table and the possible alternatives take a look at Eric Scerri’s The Periodic Table, but if you want to be entertained and find out lots of history and fascinating facts around the elements themselves, this is the one for you. Recommended. (See also Hugh Aldersey-Williams’ Periodic Tales.)

The Antigravity Enigma - Andrew May ****

Antigravity - the ability to overcome the pull of gravity - has been a fantasy for thousands of years and subject to more scientific (if impractical) fictional representation since H. G. Wells came up with cavorite in The First Men in the Moon . But is it plausible scientifically? Andrew May does a good job of pulling together three ways of looking at our love affair with antigravity (and the related concept of cancelling inertia) - in science fiction, in physics and in pseudoscience and crankery. As May points out, science fiction is an important starting point as the concept was deployed there well before we had a good enough understanding of gravity to make any sensible scientific stabs at the idea (even though, for instance, Michael Faraday did unsuccessfully experiment with a possible interaction between gravity and electromagnetism). We then get onto the science itself, noting the potential impact on any ideas of antigravity that come from the move from a Newtonian view of a...

The World as We Know It - Peter Dear ***

History professor Peter Dear gives us a detailed and reasoned coverage of the development of science as a concept from its origins as natural philosophy, covering the years from the eighteenth to the twentieth century. inclusive If that sounds a little dry, frankly, it is. But if you don't mind a very academic approach, it is certainly interesting. Obviously a major theme running through is the move from largely gentleman natural philosophers (with both implications of that word 'gentleman') to professional academic scientists. What started with clubs for relatively well off men with an interest, when universities did not stray far beyond what was included in mathematics (astronomy, for instance), would become a very different beast. The main scientific subjects that Dear covers are physics and biology - we get, for instance, a lot on the gradual move away from a purely mechanical views of physics - the reason Newton's 'action at a distance' gravity caused such ...

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...
