Bright Earth: the invention of colour

Bright Earth: the invention of colour – Philip Ball ***

It might seem that colour is too much of a physical property to be invented – but this is very much a subject open to debate, as the concept of colour – as opposed to the wavelength or energy of light – is certainly to a degree subjective. However Philip Ball’s chunky volume is not concerned purely with colour in an abstract sense but very specifically with the colour used by artists throughout the ages.

There is some fascinating stuff in here. For example, that until the 19th century ‘pink’ was not a colour at all, but was a type of paint in the same sense a lake (crimson lake etc.) was a type of paint. You could have green pink! But most of the pinks died out, leaving us with rose pink which is, of course, pink. How did little girls manage in pre-Victorian times without pink?

It is also sobering to the non-artist to realize just how much care has to be taken in the selection of pigments – and the nasty surprises that awaited artists who were too quick to try some new colour without being sure of its properties.

As always with Ball, this is a very detailed, scrupulously researched book. As if often the case with Ball’s work, the only problem is it tends to be just a bit too detailed, leading to sections that can be a trifle dull. It is indicative of the nature of popular science that when he is talking purely about pigments it’s quite easy to lose concentration, while he holds the reader much better when he is talking about particular artists.

This is without doubt a classic work on the subject (it is a re-issue: the book has been around since 2001), bound to be of interest to anyone who wants to explore the borderline between science and art, but I can’t give it any higher rating because it hasn’t quite got that page-turning zip of the best popular science.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader. We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard. This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The Infinity Machine - Sebastian Mallaby ****

It's very quickly clear that Sebastian Mallaby is a huge Demis Hassabis fan - writing about the only child prodigy and teen genius ever who was also a nice, rounded personality. After a few chapters, though, things settle down (I'm reminded of Douglas Adams' description of the Hitchhiker's Guide to the Galaxy ) and we get a good, solid trip through the journey that gave us DeepMind, their AlphaGo and AlphaFold programs, the sudden explosion of competition on the AI front and thoughts on artificial general intelligence. Although Mallaby does occasionally still go into fan mode - reading this you would think that AlphaFold had successfully perfectly predicted the structure of every protein, where it is usually not sufficiently accurate for its results to have direct practical application - we get a real feel for the way this relatively unusual company was swiftly and successfully developed away from Silicon Valley. It's readable and gives an important understanding of...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms. On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
