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.

Luna: Moon Rising (SF) - Ian McDonald ****

I'm not the natural audience for this book. Game of Thrones l eaves me cold - and it's hard not to feel the influence of GoT (and a whole lot of Dune )   underneath a veneer of science fiction and the trappings of a South American drug cartel in the cod-medieval family power battles and chivalric details. There are even dragons (of a sort). I'd be really sad if the future did involve this sort of throwback feudalism. However, remarkably, despite this I found Luna: Moon Rising kept me engaged. The fact is that Ian McDonald can put together a good plot with intricate machinations, which is enough to carry the reader through what can be a bewildering collection of characters. The two page scene-setter saying who did what to whom at the start was useful, but I could have done with family trees for the main family as I was constantly forgetting who was who - especially easy as McDonald endows many families with characters with the same first initial (e.g. Ariel and Al...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

E=mc2: A biography of the world’s most famous equation – David Bodanis *****

David Bodanis is a storyteller, and he fulfils this role with flair in E=mc2. The premise of the book is simple – Einstein himself has been biographed (biographised?) to death, but no one has picked out this most famous of equations, dusted it down and told us what it means, where it comes from and what it has delivered. Allegedly, Bodanis was inspired to write the book after hearing see an interview with actress Cameron Diaz in which she commented that she’d really like to know what that famous collection of letters was all about. Although the book had been around for a while already when this review was written (September 2005), it seemed a very apt moment to cover it, as the equation is, as I write, exactly 100 years old. So when better to have a biography? Bodanis starts off by telling us about the individual elements of the equation. What the different letters mean, where the equal sign comes from and so on. This is entertaining, though he seems to tire of the approach on...
