"Faster than the Speed of Light" is one of an increasing trend of books mixing hard science with softer autobiographical detail. I presume this is the reason it has been picked up by Arrow Books, Random House's populist brand, alongside the likes of "Charles and Camilla" and Rodney Bewes' autobiography. However, don't let its stable mates fool you. This is a true thoroughbred, and deserves far more attention than it has had to date. The scientific explanations are clearer and better written than the "Brief History of Time". As well as a canter through the history of cosmology, Magueijo, provides us with a fascinating backdrop of both his personal approach to science, and the context of how scientific research is still being carried out. For those of us who will never actually be doing this work, or as the author cuttingly puts it, give up on real science and take up finance, this is as close to the real thing as we're likely to get.
- The Science -
The first half of the book provides an explanation of the building blocks that make up the big bang theory - with no autobiography. We're treated to a quick run round special relativity, where Magueijo uses an analogy of cows travelling close to the speed of light. Despite being fairly annoying, this works very well, and is certainly memorable. We're then given a concise description of general relativity, which I'd rate as good as any that I've read, before moving off into a discussion of the big bang theory and open vs closed universes. This is where he is at his strongest, and I found myself really enjoying his explanations, particularly around the fundamental problems around the big bang. This part of the book finishes with a description of the Inflation hypothesis, which although simplified, is very clear and to the point.
- The Approach -
The second half of the book is the more autobiographical, and explains the varying speed of light (VSL) theory, or theories. As well as the science itself, it also provides a fascinating insight into where Magueijo and his collaborators get their ideas from. VSL is initially presented as the search for an alternative theory to Inflation. As the theories seem to hold water, they are developed into a wider set of hypotheses that basically take on all the big problems in cosmology. There is a more than a touch of megalomania here, which in itself is riveting. Who wakes up in the morning one day and decides to take on general relativity amd quantum gravity before breakfast? Mr Magueijo, it would seem.
- The Context -
Along with the scientific approach comes a fair dose of what could politely be called context, or less politely, office politics. Magueijo is a big personality, or as he himself puts it, "has a big mouth". As the book progresses, he allows himself a fair bit of freedom to use both. Some of his targets include: older scientists, High Table at Cambridge colleges, university administrators, male physicists who stare at women, and technical journals. I laughed like a drain, but wondered if he'll be as rude when he's over 40.
