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 AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here. We are then presented with eight paradoxes, each of which gives some insights into aspects of t...

Einstein's Fridge - Paul Sen ****

In Einstein's Fridge (interesting factoid: this is at least the third popular science book to be named after Einstein's not particularly exciting refrigerator), Paul Sen has taken on a scary challenge. As Jim Al-Khalili made clear in his excellent The World According to Physics , our physical understanding of reality rests on three pillars: relativity, quantum theory and thermodynamics. But there is no doubt that the third of these, the topic of Sen's book, is a hard sell. While it's true that these are the three pillars of physics, from the point of view of making interesting popular science, the first two might be considered pillars of gold and platinum, while the third is a pillar of salt. Relativity and quantum theory are very much of the twentieth century. They are exciting and sometimes downright weird and wonderful. Thermodynamics, by contrast, has a very Victorian feel and, well, is uninspiring. Luckily, though, thermodynamics is important enough, lying behind ...
