The Future of Agriculture - Sarah Bearchell ****

Popular science topics are fairly evenly divided between those that are of pure intellectual interest, such as astronomy or relativity, and those with a direct impact on our lives - such as climate change or quantum physics. There's often a danger with the 'direct impact' that they can be a little worthy and try too hard to be deeply meaningful. For some reason this often seems to be the case with anything food related. But thankfully agriculture is a topic that is both rarely examined and has the potential for plenty of interesting science (and history thereof).

Inevitably climate change does come into the mix, both in terms of its impact on our ability to grow crops and in the greenhouse gas emissions from cow burps, fertiliser and more. To make things more complex, with a growing world population and some parts of the world chronically short of food, we need ways to grow more without impacting the climate in a negative fashion.

It's purely coincidental that I'm reviewing this book soon after covering We Are Eating the Earth, as they have, to some degree, very different approaches to similar problem areas. Both, I think, would agree on the dubious nature of biofuels (though it's not something Bearchell addresses directly), but where Michael Grunwald in We Are Eating reluctantly admits to the environmental benefits of properly managed intensive farming, Sarah Bearchall is much more likely to be supportive of concepts like regenerative agriculture.

However, Bearchell also gives us a range of useful mechanisms to think about changing the way we interact with food and farming whether it be eating bugs, reducing waste, precision plants or automated animal rearing. This is the kind of book where you don't want lengthy expositions and Bearchell packs a lot into a slim volume.

I found the viewpoint here more challenging than I did Grunwald's - while I'm convinced of the threat of climate change, I think there is no point in preaching an ideal picture. We need pragmatic solutions that work with what people will actually do and that make best use of science like genetic modification. While not coming out as explicitly anti-GM, Bearchell can feel wary about this, and occasionally, comes across as an idealist. But being challenged in your views is not a bad thing, and it's an excellent book to read alongside Grunwald's.

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...
