The Puzzler’s Dilemma – Derrick Niederman ****

For me, the best popular science books are those that get you actively involved and thinking about what’s being looked at, rather than merely allowing you to take in the information passively. Whether it’s through exercises to get stuck into, little experiments to try out for yourself, or puzzles which challenge you to think things through – it just makes a book more enjoyable and memorable, and allows you to get more from it.

I really enjoyed this book from Derrick Niederman, then – it’s jam packed full of puzzles and logic problems which really get you thinking, and which get across well the themes covered. The puzzles slot in around what the book fundamentally is – a collection of short reflections on all kinds of aspects of puzzles and puzzle solving. We look at, for instance, how puzzles can be categorised, strategies for solving puzzles, and what puzzles can reveal about the mind and human reasoning.

One thing I found fascinating was the way we often unnecessarily complicate problems by failing to see the simple solutions to them. Asked, for example, to work out the area of a triangle with sides of 6, 8, and 14 inches, many of us would at first massively overestimate the amount of calculations and thinking we’re going to need to do to solve the problem. Whereas, in fact, the answer is simple and no difficult calculations are required. 6 and 8 equal 14, so what we essentially have is the two smaller sides lying flat on top of the longest side – the area is 0.

I found it incredibly difficult to put this book down – I either wanted to keep reading to find out the solutions to the puzzles, or was totally immersed in one of the many interesting stories the author tells about particular puzzles and their history. Add to this the author’s sense of humour, and this is one the most fun little books I have read in a long time.

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 ...
