Spatial Computing (Essential Knowledge) - Shashi Shekhar and Pamela Vold ***

A part of the increasingly interesting MIT Press Essential Knowledge series, the topic of this book may at first glance be puzzling - but it's about something many of us use every day - information technology that makes use of spatial information, such as the GPS sat nav system.

One oddity of this series is that it is very inconsistent in the level the books are pitched at. Some are way too technical for the general reader. This one, though, is a straightforward descriptive text with very limited technical detail. There's nothing here that is likely to baffle someone from outside the field and lots of information on where the various technologies have come from (including John Snow's famous map-based identification of the source of a Victorian London cholera outbreak), the basics of how they work and where they are likely to go from here.

If you actually have a need to know this stuff, it's an ideal primer. My only real concern about the book is that I'm not sure I did need to know - it felt a bit too much like doing homework. In their preface, the authors say 'How could a technology used by billions of people around the world not have an accessible guide to describe it to a broad audience?' I think, for me, the answer is 'Because it's not very interesting.' I love using this stuff, but I didn't find reading about it particularly inspiring.

That's not to say that the book won't be useful, whether you've been set an assignment on remote sensing, positioning systems or geographic information systems or you work in a field that makes use of such technology - but as a daily user of GPS, I've already got the basics and I really didn't need to detail.

For those with an interest in the field but limited knowledge, though, it's an excellent, pocket-sized introduction.

Luna: Moon Rising (SF) - Ian McDonald ****

I'm not the natural audience for this book. Game of Thrones l eaves me cold - and it's hard not to feel the influence of GoT (and a whole lot of Dune )   underneath a veneer of science fiction and the trappings of a South American drug cartel in the cod-medieval family power battles and chivalric details. There are even dragons (of a sort). I'd be really sad if the future did involve this sort of throwback feudalism. However, remarkably, despite this I found Luna: Moon Rising kept me engaged. The fact is that Ian McDonald can put together a good plot with intricate machinations, which is enough to carry the reader through what can be a bewildering collection of characters. The two page scene-setter saying who did what to whom at the start was useful, but I could have done with family trees for the main family as I was constantly forgetting who was who - especially easy as McDonald endows many families with characters with the same first initial (e.g. Ariel and Al...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

The AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here.  We are then presented with eight paradoxes, each of which gives some insights into aspects of t...
