Surfing the Quantum World - Frank Levin ***

In Surfing the Quantum World, physicist Frank Levin attempts to take a third way in communicating the marvels of quantum physics. It's not popular science. It's not a textbook. It's something in between. But is there a market for such a book?

To make this a crossover title, Levin starts with a fairly brisk trot through the history of our understanding of light and the development of quantum mechanics. You can get an idea for the briskness in that there's only one development mentioned (Alhazen's work) between Lucretius (in the last century BC) and Kepler at the end of the sixteenth century. It's rather a dark ages approach to the history of science, when they still thought there was such a thing as the dark ages. Similarly, for example, Newton gets an old-fashioned uncritical mention - and his work on light, mostly done in the in 1670s, is only referenced in terms of his 1704 publication of Opticks.

The result overall of the history bit is something that is rather more a collection of facts than an enjoyable narrative. We then get on to the serious physics, and here what we have is effectively a textbook with the workings cut out. So, for instance, Levin gives us far more detail on, say bra/ket notation than we need, and then uses it to explain various quantum mechanical developments, but doesn't give enough detail to understand what's really going on. Similarly he plunges into operators and eigenvalues and much more than is essential for the student physicist, but it's hard to see what they do for someone who just wants to be better informed and 'surf the quantum world', other than confuse the reader.

Levin covers most of the basics, from Schödinger's equation and tunnelling to entanglement and that infamous cat. However, there is a lot missing if we really want to 'surf the quantum world.' In the historical development of quantum physics, there's hardly anything about matrix mechanics, for example, and quantum electrodynamics (QED) doesn't get mentioned at all - neither is there anything really about the applications of quantum physics, which seems odd, given the book's title.

Overall, I'm afraid, the approach of developing a third way didn't work for me. If I want background and context, good popular science is by far the best way to deliver it. If I want to get into the nitty gritty and play around with kets, say, give me a proper introductory textbook - what's the point of having that level of detail without showing how to use it? Sadly, for me, the middle way fell between two stools without covering either requirement particularly well.

Ancestral Night (SF) - Elizabeth Bear *****

Only a couple of weeks ago, reviewing a 1960s SF book, I bemoaned the fact that science fiction novels of ideas are less common now. Although it is correctly labelled a space opera, Ancestral Night delivers ideas with aplomb.

Let's deal with the space opera aspect first. Elizabeth Bear provides some excellent adventure scenes in space, and we've the usual mix of huge spaceships and interesting aliens. Main character Haimey Dz is an engineer on a ship that salvages wrecks - but, as we gradually discover - she also has a forgotten past. A major feature of the storyline (one that seems to link to the medieval idea of the lost wisdom of the past) is ancient technology from a long-dead race with capabilities, notably manipulating spacetime mentally (Bear has yet to point out that the travel technologies used here could manipulate time as well as space), which fit well with Arthur C. Clarke's magic definition.

I particularly liked the (surely intentional) nods to the much-misse…

The Creativity Code - Marcus du Sautoy *****

At first glance this might just be another 'What AI is good at and not so good at' title. And in a way, it is. But, wow, what a brilliant book! Marcus du Sautoy takes us on a tour of what artificial intelligence has achieved (and possibly can in the future achieve) in a range of fields from his own of mathematics, through game playing, music, art and more.

After a little discussion of what creativity is, we start off with the now very familiar story of DeepMind's AlphaGo and its astonishing ability to take on the hugely challenging game of Go. Even though I've read about this many times before, du Sautoy, as a Go player and mathematician, gives a real feel for why this was such a triumph - and so shocking. Not surprisingly he is also wonderful on what mathematicians actually do, how computers have helped them to date and how they have the potential to do far more in the future. After all, mathematics is by far the closest science to game playing, as it has strict rule…

The Demon in the Machine - Paul Davies *****

Physicists have a habit of dabbling in biology and, perhaps surprisingly, biologists tend to be quite tolerant of it. (I find it hard to believe the reverse would be true if biologists tried to do physics.) Perhaps one reason for that tolerance is Schrödinger’s lecture series and book What is Life?, which had a huge impact on molecular biology and with a reference to which, not surprisingly, Paul Davies begins his fascinating book. 

At the heart of the The Demon in the Machine (we'll come back to that demon in a moment) is the relationship between life and information. In essence, Davies points out that if we try to reduce life to its simple physical components it is like trying to work with a computer that has no software. The equivalent of software here is information, not just in the best publicised aspect of the information stored in the DNA, but on a far broader scale, operating in networks across the organism.
This information and its processing gives life its emergent compl…
