The Reality Frame - Brian Clegg *****

I’ve read quite a few of Brian Clegg’s books, but this one’s outstanding. Relativity is a topic that many writers struggle to get across - Clegg does this brilliantly thanks to two tactics I’ve never seen before. First, he makes use of that most fundamental requirement for relativity, the frame of reference. It’s not just the title of the book that suggests frames of reference - this concept forms the backbone of his exploration of relativity. But then he goes totally mad and builds a universe from scratch!

This audacious approach enables us to see, piece by piece, that relativity is about far more than Einstein’s work - fascinating though that is. It’s not that he ignores special and general relativity. There’s even an appendix where he shows how it only takes a maths GCSE to follow the mathematics that make time dilation happen. (I'd like to see more of this kind of thing in popular science books.) But he goes far beyond Einstein's work. For example, in the final chapters he introduces life and creativity to his universe and shows the essential roles that relativity and frames of reference have to play in those cases. 

In bringing in creativity, Clegg gives the book a human focus, and this then builds to a chance to reassess humanity’s place in the universe. The book mentions Bronowski's classic The Ascent of Man, which is a brave parallel to draw, but there are some real parallels in a very different kind of book. I thought I knew the basics of relativity - yet despite never becoming over-technical, The Reality Frame really opened my eyes to a different way of looking at the universe. Clegg quotes my favourite physicist, Richard Feynman on the laws of nature - this is a chance to see those laws in a new light.

Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

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…
