Infinite Life: Jules Howard ****

There's been something of a trend for 'big picture' books that trace a feature of life, the universe or whatever from billions of years ago to the present day, arguably started by Henry Gee's excellent A (Very) Short History of Life on Earth. The new book by Jules Howard follows this trend in tracing eggs back to their earliest origins and following them step by step through to (biologically) recent times.

I was a bit wary about this one. It felt in danger of being a lengthy catalogue of eggs that would only appeal to the ovoid equivalent of a trainspotter. But I had very much enjoyed Howard's Wonderdog and found it hard to believe he wouldn't have found a way to make the story of the egg much more interesting - which on the whole he has. The slight reservation here is that there are an awful lot of species described and many variants of the egg concept. But Howard's excellent storytelling skills allow him to get away with this by giving us a series of scenarios from different eras... and also because the egg is a quite remarkable thing.

We get water-based eggs, soft shelled and hard shelled eggs on land, live birth followups to the egg and a lot of material on the quite remarkable organ that is the placenta. There are fish, amphibians, dinosaurs, insects, mammals, birds and more, all busily engaged in egg production, egg care and general eggy wonder. Sometimes it's the small details that fascinate - for example, the dark machinations of the newly hatched cuckoo in kicking its rivals out of the nest.

The one thing I was a bit surprised by was a lack of consideration of the eggs of non-egg laying mammals like us. There was lots about foetuses and the placenta - and the remarkable progress of newborn marsupials to the pouch. But hardly a mention of mammalian (and within mammals, human) eggs themselves. This seemed a strange omission. If I'm going to be picky, I would also suggest that Howard sticks to biology - early on he describes the Sun in the early years of the Earth as 'just part of a constellation' - given that a constellation is just a pattern of stars in the night sky imagined by human beings, it's hard to see how the Sun could ever have been that.

If I'm going to be really picky, I'd also query the title? Why 'infinite'? There's nothing infinity related here. Overall, though, a thoroughly enjoyable exploration of eggs through the history of life. And, of course, we now know the answer to that age old question. The egg definitely came before the chicken.

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 ...
