Tales of Militant Chemistry - Alice Lovejoy ***

I felt a touch misled by the subtitle of this book - it refers to 'the film factory'. While technically accurate, I think most people think of 'the film factory' as a term for Hollywood, where in fact what's meant here are the two photochemical giants of the era, Kodak and AGFA. Admittedly, Hollywood gets plenty of mentions, but the movie studios' use of materials from these companies is totally dwarfed by their wider use.

At the heart of the book is the chemistry necessary to make film - first based on the highly flammable cellulose nitrate and then so-called safety film (apparently no more flammable than cardboard) cellulose acetate. Parts of the companies responsible for producing these products were pressed into wartime service to make darker products, in the First World War contributing to poison gas production and in the Second World War, in the case of Kodak, centrifuging to enrich uranium. The presentation always feels as if this was not just darker, but verging on evil, even though many would argue that in wartime it's perfectly normal for companies to be required to support the war effort.

I didn't particularly enjoy this book, not because of the subject per se, but rather a warning I was issued many years ago by a literary agent: always ask, is this a book or is it a magazine article. For me, this would have made an excellent long magazine article, but to turn it into a book, Alice Lovejoy has had to put in far more information than is necessary to tell the story. This level of detail is fine if you want to use the book as an academic reference, and to be fair it is published by a university press. But I was sold the book as popular science, and it really isn't.

There's plenty of interest here, both about the development of film technology and the chemistry behind it, and on the ways Kodak and AGFA contributed to wars - but it wasn't an engaging read.

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 ...
