The Wonderful World of Relativity – Andrew M. Steane ***

This book has what is possibly the worst cover of any popular science title I’ve ever seen (even worse than the old Macmillan edition of my own Light Years, which is saying something). It’s muddy and dark – even the yellow lettering is muted. The illustration is a line drawing apparently by a ten-year-old that is just about visible on the black background. This doesn’t bode well, but of course the author isn’t responsible for the cover.
Unfortunately, the text is often equally impenetrable. The subtitle is ‘a precise guide for the general reader’ and the problem here is that there are two words in that sentence that really don’t fit well together. If you are going to be precise with a subject like special relativity, you will need to go into more maths than the general reader is comfortable with. Stephen Hawking was famously told that he would half his readership for every equation included – I reckon there are sufficient equations here to take the readership down to one.
It’s a shame, because there is the kernel of a good book here. I particularly liked the way Andrew Steane used some of the paradoxes of relativity to explore the subject. These are so good (except where he gets over-precise on us and loses most of us) that I could envisage a whole book just based on the paradoxes. Some, of course, are well worn, but I particularly liked the bug and rivet paradox (see my blog post about it here).
What this looks like is a closeted academic’s idea of what the general reader can cope with. You have to admire the author’s braveness – but ultimately it is a futile exercise because no one who isn’t about to embark on a physics degree would get anywhere with this book.
The title makes this book sounds like a Disney ride, but it’s anything but that. In the end it’s not a popular science book at all, it’s a watered down text book. And that isn’t the same thing at all, I’m afraid.

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…
