Mega Tech - Ed. Daniel Franklin ***

It's almost impossible to review a book like this without quoting Niels Bohr, who (amongst others) said 'Prediction is very difficult, especially about the future,' so I'm not going to try. 

 In principle, futurology is the most hilarious part of science writing, as it is so entertaining when unworldly academics get their predictions wonderfully wrong. (Dresses made from paper will be the norm by 2000, Dr Toffler? Really?) Yet strangely, in practice, futurology tends not to be very amusing because the books are almost always unbelievably dull to read.

 To an extent, Mega Tech gets over this by having lots of short pieces by different authors. I am often critical of the 'piecemeal appraisal' approach to a topic, because the essays rarely integrate well, but at least here it means there are nuggets of gold amongst the mediocre - notably, for example, Ann Winblad's ideas on computing based on her early experience with Bill Gates and Ryan Avent's take on the socioeconomic impact of technological development and innovation. I was also fascinated by the essay on military technology, which captured me at the start with the remarkable statistic that the current record for a sniper using a rifle is a British soldier who, in Afghanistan in 2009, shot two Taliban machine-gunners from a distance of 2,475 metres. That's further than my walk to the post office.

 Even so, some of the suggestions here already seem wide of the mark. A couple of frontrunners mentioned are virtual reality and voice interaction with technology. Both are promising, yet the authors fail to recognise that it's almost always the case that such technologies end up in a very different form to the early versions. They really need to learn the lesson I got from attending the Windows 95 launch over 20 years ago. Microsoft confidently told us in 1995 that the internet would remain a university and military domain, while the commercial future was with the commercial networks of the likes of AOL, Compuserve and Microsoft's newly launched MSN. That went well.

 Looking at the two examples I mention, virtual reality will definitely catch on, but I suspect that it will come in two forms. The book simply carries forward current headsets, but those may well only ever have a significant presence in gaming and the short-term use spaces like cinemas, not, as Mega Tech suggests, replacing our general screen use. Look at 3D TV. As I write, manufacturer after manufacturer is pulling out of 3D television production. Very few people wanted it. We're happy to wear 3D glasses to watch a 2 hour movie in the cinema, but not for our mainstream screen use. Apart from anything else, when watching the TV, we talk to others, interact with phones, eat and drink... we don't want something clamped on our face while doing this. Virtual reality in this environment is only likely to become the norm when we can do it without strapping something on.

 As for voice interaction, it's brilliant, but Mega Tech doesn't do enough to reflect its limitations. I wouldn't be without my Amazon Echo - but the book claims voice input will soon replace old-fashioned keyboards and mice/trackpads. This is only true for a subset of uses. Firstly, voice struggles outside the commonplace. I spent a hilarious ten minutes trying to get the Echo to play Schoenberg's Verklärte Nacht. I failed. Voice won't cope with this for a long time. And secondly, while many of us might be happy to dictate a tweet, have you ever tried to edit text by voice? Imagine it: 'The word "the", hang on... erm... sixteen, no, seventeen lines down on the current page, the second occurrence on the line, should actually be "thee" with a second "e" at the end of the word' is never going to seem convenient when compared with a click on the mouse and a single keypress.

 Overall, this was one of the better futurology books I've read. There were large chunks that needed skim reading to avoid them becoming tedious, but there were some really captivating points too. Indubitably most of it was wrong - but, as the introduction points out, that doesn't stop it being worthwhile speculating... as long as no one takes this as a true picture of the future.

We Are Eating the Earth - Michael Grunwald *****

If I'm honest, I assumed this would be another 'oh dear, we're horrible people who are terrible to the environment', worthily dull title - so I was surprised to be gripped from early on. The subject of the first chunk of the book is one man, Tim Searchinger's fight to take on the bizarrely unscientific assumption that held sway that making ethanol from corn, or burning wood chips instead of coal, was good for the environment. The problem with this fallacy, which seemed to have taken in the US governments, the EU, the UK and more was the assumption that (apart from carbon emitted in production) using these 'grown' fuels was carbon neutral, because the carbon came out of the air. The trouble is, this totally ignores that using land to grow fuel means either displacing land used to grow food, or displacing land that had trees, grass or other growing stuff on it. The outcome is that when we use 'E10' petrol (with 10% ethanol), or electricity produced by ...

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). ...

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 ‘Galileo discovered the counterintuitive law behind a swinging o...
