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.

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that â€˜Galileo discovered the counterintuitive law behind a swinging o...

Ctrl+Alt+Chaos - Joe Tidy ****

Anyone like me with a background in programming is likely to be fascinated (if horrified) by books that present stories of hacking and other destructive work mostly by young males, some of whom have remarkable abilities with code, but use it for unpleasant purposes. I remember reading Clifford Stoll's 1990 book The Cuckoo's Egg about the first ever network worm (the 1988 ARPANet worm, which accidentally did more damage than was intended) - the book is so engraved in my mind I could still remember who the author was decades later. This is very much in the same vein,  but brings the story into the true internet age. Joe Tidy gives us real insights into the often-teen hacking gangs, many with members from the US and UK, who have caused online chaos and real harm. These attacks seem to have mostly started as pranks, but have moved into financial extortion and attempts to destroy others' lives through doxing, swatting (sending false messages to the police resulting in a SWAT te...

Battle of the Big Bang - Niayesh Afshordi and Phil Harper *****

It's popular science Jim, but not as we know it. There have been plenty of popular science books about the big bang and the origins of the universe (including my own Before the Big Bang ) but this is unique. In part this is because it's bang up to date (so to speak), but more so because rather than present the theories in an approachable fashion, the book dives into the (sometimes extremely heated) disputed debates between theoreticians. It's still popular science as there's no maths, but it gives a real insight into the alternative viewpoints and depth of feeling. We begin with a rapid dash through the history of cosmological ideas, passing rapidly through the steady state/big bang debate (though not covering Hoyle's modified steady state that dealt with the 'early universe' issues), then slow down as we get into the various possibilities that would emerge once inflation arrived on the scene (including, of course, the theories that do away with inflation). ...
