The Fabric of the Cosmos – Brian Greene *****

Subtitled “space, time and the texture of reality”, this could be seen as yet another book trying to do all of science – but it’s more finely tuned than that – and a much better read than most of the “tell you everything” books. In fact, what Brian Greene tries to do, and largely succeeds in, is explaining the two great underlying theories of science, both developed in the twentieth century – relativity and quantum theory – then extending beyond them to the nature of time and the composition and origins of the universe.
The first section of the book concentrates on relativity (mostly special, but quickly filling in general) and quantum theory. From there we pick up a description of what time is, whether “time’s arrow” is a realistic context, and how time slots into the quantum arena. The third section is more cosmologically oriented, spending a fair amount of space on the big bang and quantum fluctuations. Then we get onto the current preferred theories of matter – string theory and its extension to bring in “branes”. Although string theory has a lot of supporters it is pure hypothesis and very likely to disappear in the future – watch out, though for some more experimentally based gems like the remarkable and often ignored Casimir force. Finally there’s a summary “what’s it all about” section, including a delightful chapter on teleporters and time machines.
Taken individually, the subjects covered in each of the first four sections could be (and are) enough material to make a good book in their own right. There’s enough here, though to get a grip on what’s involved, and the interested reader should then go on to read a book with more detail on the individual section topics. The great thing about the way Greene has written this book is that it’s never overwhelming, yet there’s an opportunity to see how it all fits together (at least as much as it does all fit together in current theory – while those underlying aspects of relativity and quantum theory are solid, it all gets more speculative as you get further in). Although it’s quite a long book – over 500 pages with the notes and index – it doesn’t feel all that long, which is a great mercy. All too often others who have attempted books on this scale have produced tomes that are more effective as doorstops than as readable popular science.
There are some minor disappointments. Greene is a great popular science writer who pitches it just right, but occasionally his popularism is a little forced, for example in his use of characters from TV shows like the Simpsons and the X Files to illustrate his example. (The use, for example, of a duel between Itchy and Scratchy in his relatively section is a bit cringe making.) The book is beautifully illustrated, but occasionally these graphics get in the way of the facts. It’s a bit like when someone first gets hold of 3D graphics in a spreadsheet, and suddenly everything is 3D – some of the points would have been much clearer with a boring old two dimensional line diagram, rather than fancy 3D shading that gets in the way of the information the diagram is supposed to put across.
Even so, this is a strong entry from Greene, and certainly one of the best popular science books of 2004.

The AI Delusion - Gary Smith *****

This is a very important little book ('little' isn't derogatory - it's just quite short and in a small format) - it gets to the heart of the problem with applying artificial intelligence techniques to large amounts of data and thinking that somehow this will result in wisdom.

Gary Smith as an economics professor who teaches statistics, understands numbers and, despite being a self-confessed computer addict, is well aware of the limitations of computer algorithms and big data. What he makes clear here is that we forget at our peril that computers do not understand the data that they process, and as a result are very susceptible to GIGO - garbage in, garbage out. Yet we are increasingly dependent on computer-made decisions coming out of black box algorithms which mine vast quantities of data to find correlations and use these to make predictions. What's wrong with this? We don't know how the algorithms are making their predictions - and the algorithms don't kn…

Infinity in the Palm of your Hand - Marcus Chown *****

A new Marcus Chown book is always a treat - and this is like a box of chocolates: a collection of bite-sized delights as Chown presents us with 50 science facts that are strange and wonderful.

The title is a quote from William Blake's Auguries of Innocence: 'To see a World in a Grain of Sand, / And a Heaven in a Wild Flower, / Hold Infinity in the palm of your hand, / And Eternity in an hour.' It would seem particularly appropriate if this book were read on a mobile phone (so it would be literally in the palm), which could well be true for ebook users, as the short essays make excellent reading for a commute, or at bedtime. I found them distinctly moreish - making it difficult to put the book down as I read just one more. And perhaps another. Oh, and that next one looks really interesting...

Each of the 50 pieces has a title and a short introductory heading, which mostly give a feel for the topic. The very first of these, however, briefly baffled me: 'You are a third mus…

How to Invent Everything - Ryan North ****

Occasionally you read a book and think 'I wish I'd thought of that.' This was my immediate reaction to Ryan North's How to Invent Everything. The central conceit manages to be both funny and inspiring as a framework for writing an 'everything you ever wanted to know about everything (and particularly science)' book.

What How to Invent Everything claims to be is a manual for users of a time machine (from some point in the future). Specifically it's a manual for dealing with the situation of the time machine going wrong and stranding the user in the past. At first it appears that it's going to tell you how to fix the broken time machine - but then admits this is impossible. Since you're stuck in the past, you might as well make the best of your surroundings, so the aim of the rest of the book is to give you the knowledge you need to build your own civilisation from scratch.
