Everything You Know About Space Is Wrong - Matt Brown ****

What we have here is a feast of assertions some people make about space that are satisfyingly incorrect, with pithy, entertaining explanations of what the true picture is. Matt Brown admits in his introduction that a lot of these incorrect facts are nitpicking - more on that in a moment - but it doesn't stop them being delightful. I particularly enjoyed the ones about animals in space and about the Moon.

Along the way, we take in space exploration, the Earth's place in space, the Moon, the solar system, the universe and a collection of random oddities, such as the fact that Mozart didn't write Twinkle, Twinkle Little Star. Sometimes the wrongness comes from a frequent misunderstanding. So, for example, Brown corrects the idea that Copernicus was the first to say that the Earth moves around the Sun. Sometimes there's some very careful wording. This is used when Brown challenges the idea that the Russian dog Laika was the first animal in space. What we discover is that, instead, Laika was the first animal in orbit, but plenty of other animals had made brief ventures into space and back beforehand. (Some even survived.)

Just occasionally, the wording goes from ambiguous to downright misleading. So, another 'fact' that's challenged is that light from the Sun takes eight minutes to reach the Earth. There was one potential challenge, in that it's actually a little over eight minutes. But Brown uses the fact that photons can take many thousands of years to get to the surface of the Sun before taking eight minutes (and a bit) to get here. And if the statement had been 'Light takes eight minutes to get from the depths of the Sun to the Earth', he would have a point. But it didn't.

Since nitpicking is the order of the day, I'd also point out that we don't know that the universe is finite, and Baa Baa Black Sheep is a variation on the theme of Twinkle Twinkle Little Star, not, as the book says, the same tune, as it has two notes that aren't in the original and several timing differences. But one of the joys of reading a book like this is looking out for things to disagree with. And it certainly is great fun to read - and a fairly quick read too. (A good thing in my book. Far took many popular science books are over-long.) Easily managed on a mid-length train journey.

The content is lightly written and produces fascinating factoids throughout, though, for some reason, the second half of the content wasn't quite as interesting as the first. And, of course, as with Brown's earlier book Everything You Know About Science Is Wrong, I bridle somewhat at the title. I know a reasonable amount about space, and most of it isn't wrong. But I suppose titling a book 'Things That Some People Think About Space (Not All the Same People) That Is Wrong' would be rather clumsy.

Lots of fun for both younger and adult readers with an interest in space or science in general.

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…
