Galloping with Light – Felix Alba-Juez ***

I’m more than a little wary of self-published books, especially ones with subtitles like ‘Einstein, relativity and folklore’, but this looked like a book that would be different from the masses – and it is. It’s not one of the interminable ‘Einstein was wrong’ books, but rather one that tries to really give an in-depth understanding of Einstein’s ideas to the general reader.
Unfortunately, Felix Alba-Juez seemed far too obsessed with the definitions of words to give us useful insights into what is going on. In the first chapter he bangs on and on about nuclear power not being based on E=mc2. It’s certainly true that, contrary to popular belief, the equation isn’t a central part of the effort to make a nuclear bomb. But his repeated assertion that the idea of converting mass to energy is folklore totally misses the point, probably because of his obsessive pursuit of the term inertia, something that in some senses doesn’t exist but is merely a reflection of Newton’s second law. There is conversion between different forms of mass-energy in nuclear reactions, and for convenience we conventionally label some aspects of this as matter and some as energy. It’s not folklore, it’s scientific convention. It’s hard not to think ‘get a life.’
Similarly in the second chapter, Alba-Juez gets all heated about the famous Einstein quote about time passing quicker with a pretty girl than sitting on a stove, suggesting that this throw-away line is generally considered an attempt to explain relativity to the common man. But it’s obviously not that. Come on, the acronym of the supposed journal is JEST. It was always supposed to be a joke – has the author no sense of humour?
And so it goes on. While the philosophical musings about the words used in relativity are mildly interesting to those who already know the area quite well, and there is a lot of good basic science in here, I can’t recommend this as a science book for the general reader. Perhaps because it’s a translation, it is just too turgid and heavy handed. Although a lot of relativity is explained, the approach is often through extremely wordy and impenetrable prose. My undergrad textbook on relativity, which I still have (A. P. French) is often more readable.
The book, with its densely packed text (the layout has too little white space), doesn’t fill the reader with the delight of science but instead is like sitting through a rather dull and decidedly nit-picking science lesson. It’s an interesting idea, but the execution disappoints.

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…
