Number Freak – Derrick Niederman ***

Things didn’t start well with me with this self-confessed ‘mathematical compendium from 1 to 200′. On the front it has a quote from Carol Vorderman. ‘This book is a complete joy. It made me smile. A lot.’ Is it really a recommendation that a book made Carol Vorderman smile? This started me off in a nervous disposition.
When it comes down to it, this is one of those books that takes a theme and batters it to death. ‘I’ll list every number between 1 and 200 and write something interesting about it,’ thought the author. (Except he couldn’t find anything at all to say about 183.) Oh, good – a bit like counting sheep. Inevitably this format leads to a forced style, but to be fair, Derrick Niederman does manage to dig up some quite interesting material (occasionally it feels like wading through one of the worse episodes of QI) about the numbers in question. At these points it can be entertaining. But all too often I found myself thinking ‘not another…[insert mathematical structure of your choice].’ It all gets a bit samey.
This is not helped by a rather limited ability on the part of the author to explain mathematical matters lucidly. Several times I found myself having to read a paragraph two or three times to try to understand what Niederman was trying to get across. Even straightforward English sometimes presents a challenge. Take this comment about the Olympic rings. ‘Although the colours of the rings – blue, black, yellow, green, and red – do not correspond to [the five regions of the world] in a one-to-one sense, each of these five colours is represented in every national flag in the world.’ Really? Where is the yellow and black in the Union Flag or the Star Spangled Banner? It just doesn’t make sense. What he probably meant is that every national flag contains at least one of these colours, but it’s not what he said, and someone writing about maths should understand the need for precision.
I’d also have been a lot happier if the book gave some explanations for some of the apparently arbitrary labels of mathematics. For instance, we are told 6 is the first perfect number (it’s the sum of the numbers that divide into it, 1, 2 and 3). I knew that. But what I didn’t know, and would like to know, is so what? What does this signify? What does it do or provide us with as a piece of information? How can we use it? It’s just left dangling.
All in all, highly curate’s-egg-like as a reading experience. It’s very rare I don’t get all the way through a book, but I confess I couldn’t be bothered to finish this one.

Artificial Intelligence - Melanie Mitchell *****

As Melanie Mitchell makes plain, humans have limitations in their visual abilities, typified by optical illusions, but artificial intelligence (AI) struggles at a much deeper level with recognising what's going on in images. Similarly in some ways, the visual appearance of this book misleads. It's worryingly fat and bears the ascetic light blue cover of the Pelican series, which since my childhood have been markers of books that were worthy but have rarely been readable. This, however, is an excellent book, giving a clear picture of how many AI systems go about their business and the huge problems designers of such systems face.

Not only does Mitchell explain the main approaches clearly, her account is readable and engaging. I read a lot of popular science books, and it's rare that I keep wanting to go back to one when I'm not scheduled to be reading it - this is one of those rare examples.

We discover how AI researchers have achieved the apparently remarkable abiliti…

The Art of Statistics - David Spiegelhalter *****

Statistics have a huge impact on us - we are bombarded with them in the news, they are essential to medical trials, fundamental science, some court cases and far more. Yet statistics is also a subject than many struggle to deal with (especially when the coupled subject of probability rears its head). Most of us just aren't equipped to understand what we're being told, or to question it when the statistics are dodgy. What David Spiegelhalter does here is provide a very thorough introductory grounding in statistics without making use of mathematical formulae*. And it's remarkable.

What will probably surprise some who have some training in statistics, particularly if (like mine) it's on the old side, is that probability doesn't come into the book until page 205. Spiegelhalter argues that as probability is the hardest aspect for us to get an intuitive feel for, this makes a lot of sense - and I think he's right. That doesn't mean that he doesn't cover all …

Colin Stuart - Four Way Interview

Colin Stuart is an astronomy journalist, author and science communicator. He has written fourteen science books to date, which have been translated into nineteen languages, including 13 Journeys Through Space and Time: Christmas Lectures From the Royal Institution and The Universe in Bite-sized Chunks both published by Michael O’Mara Books. He also has written for the Guardian, the European Space Agency and New Scientist and has spoken on Sky News, BBC News and Radio 5 Live. He is a fellow of the Royal Astronomical Society and even has an asteroid named after him. His latest title is Rebel Star: our quest to solve the great mysteries of the Sun.

Why science? 

For me the stories that you can tell with modern science rival the most imaginative leaps in fiction. The secret, invisible kingdoms of bacteria and sub-atomic particles. The logic defying realms of black holes and Big Bangs. That excites me more than Hogwarts or Mordor. The universe is an amazing place and we’ve only just scratche…
