Mage Merlin's Unsolved Mathematical Mysteries - Satyan Linus Devadoss & Matthew Harvey **

The authors of Mage Merlin's Unsolved Mathematical Mysteries don't seem to quite know who it was written for. The title and the general theming around Arthurian legend pitches it at an audience of children, maybe even young teenagers. However, the content is anything but aimed at that audience.

The book is a collection of unsolved maths problems very loosely fitted to the idea of it being a collection of questions asked of the great wizard Merlin. From such a description, or a flick through the pages, you might think that this is some kind of puzzle book for you to solve, but this isn't the case. Rather, it's a collection of relatively mundane (if esoteric) questions which despite the efforts of hundreds of years of professional mathematics we still haven't solved. With sixteen mysteries in all there is a wide selection of different kinds of problems.

For example the first question is: 'Can you cover a 201x201 meter square using six 100x100 meter squares (without cutting anything up)?' The answer to this and all of the other 'mysteries' the book poses is, 'We don't know.' It might be possible but nobody has managed to figure out a mathematical proof for it. Knowing that this is the case from the start as the book rather take the fun out of reading a new mystery.

In reading this book, it feels like it has no real audience.The Arthurian dressing feels completely perfunctory as anyone that it appeals to would almost certainly have no interest in the underlying mathematics. Additionally if you are somebody to whom such mathematical problems are of great interest the information is generally sparse and it's buried under what is essentially an annoying and unnecessary framing device.

It is worth noting that the images which make up much of the book are well designed and are used effectively to communicate what can be relatively complex puzzles to get your head around.

Overall the book looks great but feels designed for a much younger audience than its content. Whilst it offers simple to understand explanations of a number of well known unsolved mathematics problems, those looking for that kind of thing would likely do much better elsewhere.

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 New Lunar Society - David Mindell *****

David Mindell's take on learning lessons for the present from the eighteenth century Lunar Society could easily have been a dull academic tome, but instead it was a delight to read. Mindell splits the book into a series of short essay-like chapters which includes details of the characters involved in and impact of the Lunar Society, which effectively kick-started the Industrial Revolution, interwoven with an analysis of the decline of industry in modern twentieth and twenty-first century America, plus the potential for taking a Lunar Society approach to revitalise industry for the future. We see how a group of men (they were all men back then) based in the English Midlands (though with a strong Scottish contingent) brought together science, engineering and artisan skills in a way that made the Industrial Revolution and its (eventual) impact on improving the lot of the masses possible. Interlaced with this, Mindell shows us how 'industrial' has become something of a dirty wo...
