The Creativity Code - Marcus du Sautoy *****

At first glance this might just be another 'What AI is good at and not so good at' title. And in a way, it is. But, wow, what a brilliant book! Marcus du Sautoy takes us on a tour of what artificial intelligence has achieved (and possibly can in the future achieve) in a range of fields from his own of mathematics, through game playing, music, art and more.

After a little discussion of what creativity is, we start off with the now very familiar story of DeepMind's AlphaGo and its astonishing ability to take on the hugely challenging game of Go. Even though I've read about this many times before, du Sautoy, as a Go player and mathematician, gives a real feel for why this was such a triumph - and so shocking. Not surprisingly he is also wonderful on what mathematicians actually do, how computers have helped them to date and how they have the potential to do far more in the future. After all, mathematics is by far the closest science to game playing, as it has strict rules established beforehand, where with most other sciences we really don't know what the rules are and have to try to work them out as we go along.

My only slight moan about the mathematical aspect of the content is that there are so many references to the mathematical discipline of symmetry and group theory that it would have been nice to have had an a little backgrounder on these to put what is being talked about into context. Having said that, though, given the inevitably slightly scary aspect of AI potentially taking over some of the roles of mathematicians, du Sautoy gives us an excellently balanced and fair assessment of how some mathematical AI projects really do very little to advance the field, while others really do eat into the mathematician's work.

Perhaps my favourite chapters of all were those on music. There is, of course, a distinctly algorithmic feel to composition theory, and du Sautoy really makes his exploration of this delightful. I'm familiar with a lot of Bach's work, but not The Musical Offering - which du Sautoy argues well was a particularly algorithmic feat. Apparently, Bach was asked if he could improvise a fugue from a very tricky 'tune' dreamed up as a challenge by Frederick the Great - not only did Bach manage a three part version on the spot, he went on to compose 11 variants using all sorts of remarkable modifications. A particular bonus was being able to summon up The Musical Offering on Spotify (itself an algorithmic marvel on a good day) and listen to it as I read the book.

I wasn't quite as taken with the sections on art. With modern art it's arguable that it's pretty much impossible to define what good art is (du Sautoy points out how difficult it is to fake a Jackson Pollack if you know technically what to look for... but I still find his paintings a visual mess that I wouldn't hang in the toilet, so I don't really care that it's hard to reproduce). With such an arbitrary borderline between creativity and randomness, it's hard to worry too much about what an AI can do - it all seems to be a matter of fashion anyway. These chapters were still interesting, just less significant for me. My interest revived, though, when he got onto approaches to writing, even if there was nothing there that seemed likely to displace human work any time soon.

All in all, a great crossover title between computing, mathematics and creativity, presented with du Sautoy's usual charm and clarity. Excellent.

The Meteorite Hunters - Joshua Howgego *****

This is an extremely engaging read on a subject that everyone is aware of, but few of us know much detail about. Usually, if I'm honest, geology tends to be one of the least entertaining scientific subjects but here (I suppose, given that geo- refers to the Earth it ought to be astrology... but that might be a touch misleading). Here, though, there is plenty of opportunity to capture our interest. The first part of the book takes us both to see meteorites and to hear stories of meteorite hunters, whose exploits vary from erudite science trips to something more like an Indiana Jones outing. Joshua Howgego takes us back to the earliest observations and discoveries of meteorites and the initial doubt that they could have extraterrestrial sources, through to explorations of deserts and the Antarctic - both locations where it tends to be easier to find them. I, certainly, had no idea about the use of camera networks to track incoming meteors, which not only try to estimate where they wi...

Phenomena - Camille Juzeau and the Shelf Studio ****

I am always a bit suspicious of books that are highly illustrated or claim to cover 'almost everything' - and in one sense this is clearly hyperbole. But I enjoyed Phenomena far more than I thought I would. The idea is to cover 125 topics with infographics. On the internet these tend to be long pages with lots of numbers and supposedly interesting factoids. Thankfully, here the term is used in a more eclectic fashion. Each topic gets a large (circa A4) page (a few get two) with a couple of paragraphs of text and a chunky graphic. Sometimes these do consist of many small parts - for example 'the limits of the human body' features nine graphs - three on sporting achievements, three on biometrics (e.g. height by date of birth) and three rather random items (GNP per person, agricultural yields of various crops and consumption of coal). Others have a single illustration, such as a map of the sewers of Paris. (Because, why wouldn't you want to see that?) Just those two s...

Against the Odds - John Gribbin and Mary Gribbin ****

The number of women working in STEM subjects has expanded dramatically, but as John and Mary Gribbin make clear, in the history of science this is a very recent occurrence. Here, they bring us the stories of 12 women, from Eunice Newton Foote, born in 1819, to Vera Rubin, born in 1928 - effectively covering nearly 200 years in that Rubin died as recently as 2016. There are some names that will already be familiar from popular science histories (and deservedly so). You will find, for instance, Dorothy Hodgkin and Rosalind Franklin represented. But there are plenty like Foote that few will have come across, including Inge Lehmann, Chien-Sung Wu and Lucy Slater. While arguably Foote is there primarily to demonstrate the difficulties she faced (her discovery of an aspect of greenhouse gas behaviour was independently bettered within weeks), the rest have all made significant discoveries or developments against the odds and often missed out the recognition the deserved. The most prominent ob...
