Genome – Matt Ridley *****

The output of the human genome project is a heavy duty subject – just understanding what’s involved in the process is not easy; interpreting the results operates at a wholedifferent level. As for writing about the human genome in an accessible and enjoyable way – this is a particularly drastic challenge.

Ridley not only succeeds but does so in a rather cute fashion. This is ‘an autobiography of a species in 23 chapters’. The number 23 is no random selection – it corresponds to the number of chromosome pairs we have, and Ridley picks out a gene to feature from each chromosome pair in each chapter.

This approach enables his book to be far reaching, looking at our relationship to other owners of the gene, from bacteria to great apes, spanning from the earliest forms of life to the genes that could be responsible for intelligence and language.

Evolutionary theory, biology’s great triumph, is put across very effectively alongside good background material on genetics, and of the many books around the human genome, this has to be one of the best.

Particularly attractive is Ridley’s style – effortlessly informative, yet light enough to almost always be enjoyable. If there’s anything to criticize it is an over use of something to the effect of “to go through all of this would bore you to tears, but I just want to show you this little bit because…” – but that is a very minor moan.

This reviewer has a physics background and expects biology-based popular science to often be an necessary chore rather than a pleasure – this is a definite exception!

It’s interesting to read it alongside Andrew Brown’s In the Beginning was the Worm.

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

The Language of Mathematics - Raúl Rojas ***

One of the biggest developments in the history of maths was moving from describing relationships and functions with words to using symbols. This interesting little book traces the origins of a whole range of symbols from those familiar to all, to the more obscure squiggles used in logic and elsewhere. On the whole Raúl Rojas does a good job of filling in some historical detail, if in what is generally a fairly dry fashion. We get to trace what was often a bumpy path as different symbols were employed (particularly, for example, for division and multiplication, where several still remain in use), but usually, gradually, standards were adopted. This feels better as a reference, to dip into if you want to find out about a specific symbol, rather than an interesting end to end read. Rojas tells us the sections are designed to be read in any order, which means that there is some overlap of text - it feels more like a collection of short essays or blog posts that he couldn't be bothered ...
