Antimatter – Frank Close ****

I like this little book. Regular readers of my reviews will know that ‘little’ isn’t an insult – there’s nothing worse than a bloated, over-inflated popular science book. This one delivers the goods on the subject without resorting to endless padding. The subject in question is antimatter, which Frank Close covers with just enough context – particular the US Air Force’s interest in antimatter weapons, and Dan Brown’s awful antimatter-based thriller Angels and Demons – to keep the reader interested.

It’s a bit of a Brief History of Time kind of book. Before Dr Close gets all excited and waits for the royalties to come crashing in, I don’t really mean that I expect it to have the same kind of popularity of ABHoT, but rather it has the same tendency to plunge into just a bit too much depth and not necessarily to explain the science in a way that comes across well to the uninitiated. Having said that, there is some good writing here explaining why antimatter is so important and how the Big Bang could have result in mostly matter.

Even if you know a bit about antimatter, there are some surprises. And what’s lovely is the way the book really thinks about the practicalities of antimatter. You can’t store antiatoms, for instance, because they aren’t charged, so you can’t keep them in an electromagnetic container away from matter. But you can’t have billions of positrons or antiprotons in the same place either, because they repel each other. I wasn’t clear why you can’t use an anti-plasma – I wish that had been covered.

The presentation is just a touch dry – this is very obviously a book written by an academic who is trying hard to be populist but not quite making it – which is why it only gets four stars rather than five. And I don’t think he does any favours by suggesting that many people seriously think the Tunguska fireball was antimatter. But it’s a really interesting book that stretches the brain and that is packed with glowing little antimatter nuggets.

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 ...
