Slow Rise - Robert Penn ****

There are two provisos here - first, this is primarily not a science book, but has enough science scattered through it to be worth covering. And second, I'm giving this book four stars because I enjoyed reading it despite its irritating flaws. It's a bit like a film I watched the other day in which an American actor did one of the worst Scottish accents I've ever heard. I still managed to enjoy the film, but I had to work at ignoring it.

In Slow Rise, Robert Penn provides a memoir of his attempt to produce a year's worth of bread for his family using traditional wheat varieties he has grown and converted into flour himself. This may sound a bit like one of those amusing self-challenge books that Tony Hawks does so well, and there certainly is an element of humour in Penn's self-deprecating comments when things go wrong. But here this is also combined with some really interesting material on the biology and nature of wheat and the technical details of the bread-making process.

Along the way, Penn visits various growers of ancient wheats (and factory-scale harvesters), talks with flour and bread fanatics and samples a whole range of exotic bread types before settling on his own wholemeal sourdough, made from a combination of emmer wheat, one of the main standards a couple of millennia ago, and a Welsh wheat variant that would have been popular in medieval times.

As well as finding a lot to like in Penn's storytelling and the occasional, cosmetic advert style 'now the science bit' (my label, not his), I was convinced by his argument that modern white bread is far more likely to be responsible for some of today's digestive problems than gluten, and that going for quality bread made with good wholemeal flour is well worth spending extra on. However, I can't entirely ignore the two main irritations.

The first is that Penn very much portrays a 'back to nature', caring for the environment ethos, taken sometimes to ridiculous extremes when, for example, he ploughs a field with a horse-drawn hand plough. Yet he's even worse than Brian Cox at jetting off all over the world to have a cameo appearance in the wheat fields of middle America or to search out an ancient grain in Turkey. I find a degree of hypocrisy in speaking up for thinking more of the environment (which is of genuine importance) while flying across the world. The other issue I have is Penn repeatedly refers to organic flour as if being organic makes any difference to the quality, rather than being a marketing tool to charge more. Where he makes a good case for the benefits of good quality wholemeal and lack of additives, he makes no case for organic (which is hard to do for a system so embedded with woo and lacking evidence of benefits), but simply assumes it's better.

Despite the genuine irritants (a bit like those additives in many loaves) this remains a book I'm glad I read and can happily recommend.

  1. The several praising revs of this book don't mention its serious drawbacks. Although much based on historical claims and interpretations, it cites no sources for them: no fns, no biblio--just 'selected readings'. Despite introducing technical terms, it lacks an index, which could be made in minutes by word search. The publisher, Particular Books, seems not particular. Editing: e.g., having until then read of bread entirely in terms of the history of wheat, on p. 80 we have bold claims about its importance from medieval to early modern times, only to be told 18 pp. later that in that pd (& up to the late 19th C) it was mainly rye and barley.

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...

In Seach of Sea Dragons - Matthew Myerscough ****

It's common advice to would-be authors of narrative non-fiction to open with something dramatic - Matthew Myerscough certainly does this with the story of his being trapped under an avalanche on Snowdon (while his girlfriend, also carried away remains on top of the snow unhurt). It certainly is dramatic, but seemed entirely disconnected from the reason I got the book, which was to read about fossil collecting.  Luckily, though, in the second chapter we get into a more conventional 'how I got interested in fossils as a boy'. Having recently reviewed Patrick Moore's autobiography and noting that astronomy was one of the few sciences where amateurs can still make a contribution, it came to mind that palaeontology is another - Myerscough is a civil engineer by trade, but just as amateur astronomers can find new details in the skies, so amateur fossil hunters have been searching for these relics for centuries. When I give talks in junior schools, the two topics that guarant...

Robot-Proof - Vivienne Ming ****

As Vivienne Ming makes apparent, there seem largely to be two views of AI's pros and cons, both of which are almost certainly wrong. It's either doom-saying 'It'll destroy life as we know it' or Pollyanna-ish 'It'll do all the boring work and we can all be wonderfully creative and live lives of leisure.' Instead, Ming gives us a clear analysis of the likely trajectory for the workplace, particularly for the IT industry. She describes three 'equally flawed, intellectually lazy strategies' to deal with the impact of AI. The first is substitution and deprofessionalisation, using AI to allow cheaper 'AI-augmented technicians' to replace more expensive professionals, producing more low wage jobs and fewer mid-range. This does save money but leaves a company at risk of being easily outcompeted. The second is what Ming describes as the '"A-Player" Hunger Games', the approach favoured by Silicon Valley. This sees the growing rif...
