Pocket Einstein: 10 Short Lessons in Artificial Intelligence and Robotics - Peter Bentley ****

Another handsome little hardback in the '10 short lessons' format that manages to pack in a surprising amount of information. AI is a subject where it's easy to get carried away with enthusiasm for the wonders of the subject, so we end up with much marvelling about too little substance - a trait that has dogged the AI profession leading a couple of 'winters' where it over-promised and under-delivered. Thankfully, Peter Bentley largely avoids this trap. Although he is certainly broadly positive about the topic, he does make some of the shortcomings clear.

The book is genuinely interesting and carries the reader along with a light touch that never betrays the author's academic background - it is a heartfelt compliment that this is a book by a professor that feels like it was written by a science writer. We get a good mix of the history with a brief explanation of how the technology works and a broad exploration of applications, both what has already been achieved and what may be possible.

Bentley manages to squeeze in robotics as well as AI, which was interesting as there have been a lot of books on AI of late, but not so many on robots - both what they do well and what they do badly. Here, as elsewhere, Bentley gives us a really good insight into the history and background. On the AI side, there is good mix of the different approaches, and a reasonable suppression of the inclination of some to over-worry about impending AI doom as the things become more intelligent than us and take over the world. As someone else said, it's more artificial unintelligence - brilliant at specific tasks, but lacking the core of what we would largely regard as intelligent ability. 

Inevitably, there are few things that could be done differently. The explanation of neural networks is just a bit too simple to really understand what's going on. And although Bentley doesn't whitewash the field, mentioning, for example, that it could be a long time before we accept autonomous cars, he doesn't entirely address the transparency problem - not understanding how an AI came to a decision, making it difficult to assess whether it made a mistake - or the ease with which these algorithms can be fooled. Also we are told, for example, of how brilliant AIs are now at image recognition, but Bentley doesn't really explore the way they require millions of examples to get it right, where a child can do it with a handful of examples.

There is always a danger with this kind of quick-and-simple introduction book that it feels like the author is talking down to the reader. This doesn't happen at all here - although it could comfortably be read by an interested teenager, it really does feel like a book that is addressed to adults, taking on a complex topic with a comfortable ease. Ideal for a commuting read or a relaxing evening listening to music provided by an AI system.

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...

How to Keep a Plane in the Sky - Alex Davies ****

If there's one big gap in the science writing sphere, it's popular engineering (you can quibble over whether engineering is science, but where else would you put popular engineering?). Alex Davies does the field a real service with this insightful introduction to the world of test engineering. The concept is simple. If we build something and sell it, we need to test it to make sure that it won't fail in a way that's dangerous to the consumer. The most obvious example is airliners, which feature at some length, but this applies to everything from cuddly toys to hair straighteners: someone needs to predict what could go wrong and to put the product through its paces to see if it will survive under any reasonable circumstances. When Davies is telling a story of test engineering in action, the book is a delight. He opens with the way that real bears are used to test if bears can get into coolers and trash cans - and the impressive ways these animals can  circumvent human in...

On the Equality of All Things - Carlo Rovelli ****

There is a wide gulf between the worldviews of physicists and philosophers. Many physicists present a rather sweetly naive, child-like view of the world, where philosophers bring a distinctly more adult, cynical tone. This being the case, it can be a little worrying when a physicist dips a toe into the philosophical mire. Infamously, in The Grand Design , Stephen Hawking and co-author Leonard Mlodinow told us that philosophy was now dead because science could deal with anything it had previously been needed for. Thankfully, Carlo Rovelli is not trying to do away with philosophy, though it has to be said that when he veers into the topic that physicist's naivety can make it feel like the philosophising of an earnest eighteen-year-old. Take the opening paragraph, which tells us 'electrons and minds, stones and laws, judgements and galaxies do not essentially differ in nature from one another. They are notions that illuminate each other'. I almost expected a Pink Floyd soundtr...
