Snapshot (SF) - Brandon Sanderson ****

Although a science fiction story is just as capable of having all the usual furniture of a novel - character building, human reactions, locations and environment and so on - there is the added depth science fiction gains by being a genre of ideas. Some of the early greats of science fiction - Asimov, for example - managed the ideas and the 'What if?' far more eloquently than they did the traditional elements of fiction writing, presenting us with cardboard characters. Although Snapshot is nowhere near as bad as the old brigade in this respect, there is no doubt that Brandon Sanderson scores significantly more on the 'What if?' aspect. This is very much an idea-driven novella.

It's a dramatic idea at that. What if it were possible to recreate a day in a city with all its inhabitants, going through exactly what happened on the day? It would enable, for instance, police officers to go in and attempt to solve a crime, able to revisit the scene and interact with those involved. But Sanderson piles on the implications by making this not a virtual reality recreation, but a meatware one. By means we'll come back to, the whole physical reality of the city is recreated, then destroyed again at the end of the day. And to make the whole thing more laden with ethical dilemmas, the police officers carry a badge that makes inhabitants of the recreated city aware that they are copies who have less than a day to live.

Although some aspects of the story are a little predictable (Sanderson, in his afterword, actually says that he assumed that readers would guess one major twist), others still manage to surprise. It's a nicely constructed story within that jaw-dropping concept of a physical recreation of the city.

There are, I suppose, two issues to be addressed. One is that, as mentioned above, this is a novella, not a full length novel. I've a lot of time for the novella format, and they work well as ebooks, but I would usually expect it to be accompanied in physical form by a good bunch of short stories. Here it's left to fend for itself, and it's possible that a book that can be read on a shortish train journey is one that feels a little skimpy for the price.

The other issue is one that, again, Sanderson brings up in his postscript. The mechanism here is pure magic (though given a vague science-like wrapper with hints of an alien involvement). It has to be magic when you think about it. It's physically impossible to recreate anything at a quantum level other than making a copy and destroying the original. The practicalities are endlessly impossible (how to capture all the information, how to store it, how to manufacture the objects and people, what happens at the boundaries etc. etc.). So it requires a little more suspension of disbelief than most SF. I was also slightly surprised that Sanderson didn't refer to one of my favourite movies, Inception, when talking about the inspiration for the story - it's hard to read this and to believe that he's never seen Inception.

Overall, though, a truly interesting novella, which, though hardly creating deep characters, at least has some magnificent ideas to play with.

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.

We start with a fun flow chart for working out just how far back in time you are…
