Planting Clues: David Gibson ***

The pedants amongst us have to start by raising an eyebrow at the subtitle (supertitle?) 'how plants solve crimes'. Plants do not solve crimes - people solve crimes. What was intended was more 'how plants are used by forensic scientists to help them solve crimes' - but I suppose that's not so snappy.

In theory, this should be a page turner as a book as it combines science with real-life drama. We're told a fair number of true crime stories where plants have been used as vital evidence. But, unfortunately, David Gibson does not have a flair for storytelling and it all comes across as rather flat. It doesn't help that there's such a focus on US law, with only passing references to Europe/UK - and most puzzling of all, on a regular basis a story will start with something like 'In 1997, Merle and Nicky Merlaue (not their real names) bought waterfront property...' Why don't we get their real names? Presumably the court cases are a matter of public record. And if there really is a reason for not using someone's names, why name them at all? It's just irritating.

There is some genuinely interesting material here on the way that everything from diatoms in a drowned person's bone marrow (that was the one I found most fascinating - it shows if someone was alive when immersed) to the DNA of a specific plant has been used to help bring a criminal to justice or to settle a legal case. Gibson gives us some historical context and compares the early attempts with what's now possible - but also emphasises the limits of appropriate expertise. But, after a while, the different plant identifying methods and how they are used to place someone at a scene get a little repetitive.

Almost as if recognising this, the book finishes with two long chapters that aren't really quite the same thing. One is about poisons (where the distinction between plant and non-plant is not really significant), and the other about people importing plants that they shouldn't. Admittedly this one does involve plant-based forensics, but it's harder to get excited about a garden centre having illegal purple loosestrife on sale, compared with plant residue providing evidence that will help solve a murder.

You can't fault Gibson's enthusiasm for the subject - and I suspect would-be botanists will enjoy it, while murder mystery writers will gain some excellent ideas for methods that their CSI teams can use. Unfortunately, though, I never really found the book engaging.

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 ...
