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.

I, Mammal - Liam Drew *****

It's rare that a straightforward biology book (with a fair amount of palaeontology thrown in) really grabs my attention, but this one did. Liam Drew really piles in the surprising facts (often surprising to him too) and draws us a wonderful picture of the various aspects of mammals that make them different from other animals. 

More on this in a moment, but I ought to mention the introduction, as you have to get past it to get to the rest, and it might put you off. I'm not sure why many books have an introduction - they often just get in the way of the writing, and this one seemed to go on for ever. So bear with it before you get to the good stuff, starting with the strange puzzle of why some mammals have external testes.

It seems bizarre to have such an important thing for passing on the genes so precariously posed - and it's not that they have to be, as it's not the case with all mammals. Drew mixes his own attempts to think through this intriguing issue with the histor…

Foolproof - Brian Hayes *****

The last time I enjoyed a popular maths book as much as this one was reading Martin Gardner’s Mathematical Puzzles and Diversions as a teenager. The trouble with a lot of ‘fun’ maths books is that they cover material that mathematicians consider fascinating, such as pairs of primes that are only two apart, which fail to raise much excitement in normal human beings. 

Here, all the articles have something a little more to them. So, even though Brian Hayes may be dealing with something fairly abstruse-sounding like the ratio of the volume of an n-dimensional hypersphere to the smallest hypercube that contains it, the article always has an interesting edge - in this case that although the ‘volume’ of the hypersphere grows up to the fifth dimension it gets smaller and smaller thereafter, becoming an almost undetectable part of the hypercube.

If that doesn’t grab you, many articles in this collection aren’t as abstruse, covering everything from random walks to a strange betting game. What'…

A Galaxy of Her Own - Libby Jackson ****

This is an interesting book, even if it probably tries to be too many things to too many people. I wondered from the cover design whether it was a children's book, but the publisher's website (and the back of the book) resolutely refuse to categorise it as such. The back copy doesn't help by saying that it will 'inspire trailblazers and pioneers of all ages.' As I belong to the set 'all ages' I thought I'd give it a go.

Inside are featured the 'stories of fifty inspirational women who have been fundamental to the story of humans in space.' So, in some ways, A Galaxy of Her Own presents the other side of the coin to Angela Saini's excellent Inferior. But, inevitably, given the format, it can hardly provide the same level of discourse.

Despite that 'all ages' comment and the lack of children's book labelling we get a bit of a hint when we get to a bookplate page in the form of a Galaxy Pioneers security pass (with the rather worrying…
