Seven Brief Lessons in Physics - Carlo Rovelli ***

This strikes me as the kind of book that would really impress an arts graduate who thought it was giving deep insights into science in an elegant fashion, but for me it was a triumph of style over substance - far too little content to do justice to the subject. It is, in effect, seven articles strung together as a mini-book that can be read comfortably in an hour, but is priced like a full-length work.
Don't get me wrong, Carlo Rovelli knows his stuff when it comes to physics and gives us postcard sketches of a number of key areas, mostly in the hot fields like cosmology and quantum gravity (though interestingly focussing on the generally rather less popular loop quantum gravity). However he's not so good on his history of science, and can, as scientists often do when writing for the general public, over-simplify.
The last of the articles is different from the rest - rather than take in a specific field (quantum physics, say) as the earlier articles do, it looks at how people and science interact. In some ways this is the freshest and most interesting part of the content... it's just hard to see why it's a 'lesson in physics.'
This book came across to me like a taster menu from a fancy restaurant. It will certainly hit the mental tastebuds, and contains a number of delights - but it is insubstantial and leaves you wanting far more. I can see the title doing very well as a gift book. It looks pretty and is handsomely bound, but there are plenty of better options out there if a reader really wants to be introduced to the wonders of modern physics.

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…
