A Wealth of Numbers – Benjamin Wardhaugh ***

I’m probably the last person who should be reviewing this book because quite a bit of  it is about mathematical puzzles, and I’m hopeless with these. I enjoy them as long as I can get the answer off the top of my head within 30 seconds – then I feel smug. But otherwise  I get bored, and I’m certainly not going to do anything that involves writing out a series of equations.
That’s perhaps a bit picky, though. Because the book has a much wider brief than mathematical puzzles and diversions – it provides us with many excerpts from maths books aimed at the general reader over the last five hundred years. As such it’s a box of curiosities. Reading it is a bit like going around one of those really old fashioned, fusty local museums. A lot of the stuff you see you think ‘Why are they bothering to display this?’ But then you will come across a little gem like a mummified mermaid and it is all, briefly, worthwhile.
So it is, for example, quaintly interesting to see extracts from Robert Recorde’s famous sixteenth century mathematical textbooks, giving us instructions in how to add two numbers together, or to dally with the mathematical problems set in The Girls’ Own Book(even if I had to read the answer to one several times to understand what it was getting at). But there was a lot that wasn’t particularly thrilling.
I may be biassed but I think I got more from some of the science writing that somehow  creeps in (who couldn’t enjoy A Mother Explains Comets from 1823 or the incomparable Richard Feynman on The Character of Physical Law) but I can see for the enthusiast for the history of popular maths writing this is a must-have book. I just suspect that this is a relatively limited market. For the rest of us, it would liven up a wet weekend in Margate, but would be trumped by most other entertainment.

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…
