The Reality Frame - Brian Clegg *****

I’ve read quite a few of Brian Clegg’s books, but this one’s outstanding. Relativity is a topic that many writers struggle to get across - Clegg does this brilliantly thanks to two tactics I’ve never seen before. First, he makes use of that most fundamental requirement for relativity, the frame of reference. It’s not just the title of the book that suggests frames of reference - this concept forms the backbone of his exploration of relativity. But then he goes totally mad and builds a universe from scratch!

This audacious approach enables us to see, piece by piece, that relativity is about far more than Einstein’s work - fascinating though that is. It’s not that he ignores special and general relativity. There’s even an appendix where he shows how it only takes a maths GCSE to follow the mathematics that make time dilation happen. (I'd like to see more of this kind of thing in popular science books.) But he goes far beyond Einstein's work. For example, in the final chapters he introduces life and creativity to his universe and shows the essential roles that relativity and frames of reference have to play in those cases. 

In bringing in creativity, Clegg gives the book a human focus, and this then builds to a chance to reassess humanity’s place in the universe. The book mentions Bronowski's classic The Ascent of Man, which is a brave parallel to draw, but there are some real parallels in a very different kind of book. I thought I knew the basics of relativity - yet despite never becoming over-technical, The Reality Frame really opened my eyes to a different way of looking at the universe. Clegg quotes my favourite physicist, Richard Feynman on the laws of nature - this is a chance to see those laws in a new light.

Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

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 ...
