Scarcity - Sendhil Mullainathan and Eldar Shafir ****

There is no scarcity of books about the brain and psychology and emotion. In fact, the shelves are groaning with them. But here's a psychological take on what you might regard as a problem of economics - and that makes it genuinely fascinating. So it's a shame that it doesn't work better as a book - but this is one of those titles that you will want to read despite that.

The authors Sendhil Mullainathan and Eldar Shafir look at the nature of scarcity and, crucially, the effect it has on human performance. You might hear the term and think it's about going hungry - and that is one example of scarcity - but they also look at what happens when money, time and even friends are in short supply. Although they aren't exact analogues, all have related impacts on us as human beings.

By referencing the best available studies (and doing a few of their own), the authors come to some important conclusions. Scarcity isn't all bad. It concentrates the mind - gives us focus. But there is a price to pay for being in that tunnel. It means that other essential aspects of life get ignored. And, most strikingly, what the authors call 'bandwidth' - a combination of cognitive ability and ability to concentrate - is reduced. They call this a 'bandwidth tax'.

So far, so engaging. We aren't just offered the symptoms and diagnosis, but also some attempts to counter this. Pointing out, for instance, that it's better for people to make decisions and learn things when they are going through a good phase than through scarcity. However I have two problems with this as a book. One is that while it's no textbook, it really isn't particularly readable - it takes a really interesting subject and makes it a bit dull. And the other is that there are strong signs that this is really a magazine article, not a book. For page after page the same thing is said in subtly different ways. If I see the word 'bandwidth' again today, I'll scream. The meat of this book could easily fit in 4,000 words.

So, paradoxically, I do urge you to read the book, as the subject is well worth exploring - but I can't promise that you will enjoy the experience.

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 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 ...

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 ...
