Einstein and Relativity – Paul Strathearn ***

This is part of author Paul Strathern’s ‘Big Idea’ series, with each book in the series aiming to provide a condensed, readable introduction to a particular scientist’s life and work. The format is the same each time, so we also have, for instance, ‘Darwin and Evolution’, ‘Curie and radioactivity’ and ‘Newton and Gravity’.
This offering on Einstein really is very short – at under 90 pages, it can be read in about 90 minutes. Still, Strathern manages to get in a good overview of the major episodes of Einstein’s life, encompassing his political activities and his ultimately unsuccessful work towards the end of his career on unification, and we get some insights into Einstein as a person.
Clearly, given the length of the book, you will need to go elsewhere to get a full account of relativity. But, again, the book does well to fit in what it does into such a small amount of space. We get brief but useful explanations of the special and general theories, Einstein’s thinking whilst coming up with each, and the context within which the breakthroughs were made. And via discussions of the Michelson-Morley experiment, the differences between Galilean relativity and Einstein’s relativity, and the action at a distance problem in Newton’s theory of gravitation, the truly revolutionary nature of Einstein’s theories comes through.
The book is easy to read throughout and would be particularly good for those new to popular science, and as something to look at before going on to, say, Walter Isaacson’s detailed Einstein: his life and universe. All in all, this is a useful summary of the man and his ideas, which definitely has a place in the popular science genre.

The Great Silence – Milan Cirkovic ****

The great 20th century physicist Enrico Fermi didn’t say a lot about extraterrestrial life, but his one utterance on the subject has gone down in legend. He said ‘Where is everybody?’ Given the enormous size and age of the universe, and the basic Copernican principle that there’s nothing special about planet Earth, space should be teeming with aliens. Yet we see no evidence of them. That, in a nutshell, is Fermi’s paradox.

Not everyone agrees that Fermi’s paradox is a paradox. To some people, it’s far from obvious that ‘space should be teeming with aliens’, while UFO believers would scoff at the suggestion that ‘we see no evidence of them’. Even people who accept that both statements are true – including  a lot of professional scientists – don’t always lose sleep over Fermi’s paradox. That’s something that makes Milan Cirkovic see red, because he takes it very seriously indeed. In his own words, ‘it is the most complex multidisciplinary problem in contemporary science’.

He points out th…

The Order of Time - Carlo Rovelli ***

There's good news and bad news. The good news is that The Order of Time does what A Brief History of Timeseemed to promise but didn't cover: it attempts to explore what time itself is. The bad news is that Carlo Rovelli does this in such a flowery and hand-waving fashion that, though the reader may get a brief feeling that they understand what he's writing about, any understanding rapidly disappears like the scent of a passing flower (the style is catching).

It doesn't help either that the book is in translation so some scientific terms are mangled, or that Rovelli has a habit of self-contradiction. Time and again (pun intended) he tells us time doesn't exist, then makes use of it. For example, at one point within a page of telling us of time's absence Rovelli writes of events that have duration and a 'when' - both meaningless terms without time. At one point he speaks of a world without time, elsewhere he says 'Time and space are real phenomena.'…

The Happy Brain - Dean Burnett ****

This book was sitting on my desk for some time, and every time I saw it, I read the title as 'The Happy Brian'. The pleasure this gave me was one aspect of the science of happiness that Dean Burnett does not cover in this engaging book.

Burnett's writing style is breezy and sometimes (particularly in footnotes) verging on the whimsical. His approach works best in the parts of the narrative where he is interviewing everyone from Charlotte Church to a stand-up comedian and various professors on aspects of happiness. We get to see the relevance of home and familiarity, other people, love (and sex), humour and more, always tying the observations back to the brain.

In a way, Burnett sets himself up to fail, pointing out fairly early on that everything is far too complex in the brain to really pin down the causes of something as diffuse as happiness. He starts off with the idea of cheekily trying to get time on an MRI scanner to study what his own brain does when he's happy, b…
