Venus - William Sheehan and Sanjay Shridhar Limaye ***

After reading this impressively illustrated book, you will know a lot about the planet Venus - almost too much. In terms of the volume of content and colour illustrations it's hard to fault, I just felt like I was being given too much information without enough contextual narrative. This is always a balance with popular science: for me this was more like reading a very long Wikipedia entry than an effective book.

Having said that, unless you are already deeply immersed in Venus and its history, there is no doubt that you will learn plenty along the way. William Sheehan and Sanjay Shridhar Limaye start us of with pre-science. We discover how early civilisations regarded Venus (whether as one item or separate morning and evening stars) and the range of myths attached to the planet. The authors then bring in telescopes and, to a degree, the disappointment that gets a better look at Venus did not reveal more, thanks to the planet's permanent, thick cloud cover.

The remainder of the book brings in spectral analyses of the Venusian clouds, what has been discovered using radar and spacecraft, the detailed composition of the clouds, what we know of the surface, how speculation about life on Venus has changed and the different ways that Venus has been observed. And, of course, there are large amounts of material on transits of Venus which, apart from their romantic association with fiction always strike me as deeply boring, considering how much effort went into measuring them. They were important in their day, but still... There's certainly plenty of information and data on a planet that we still know relatively little about.

It's not that there is no narrative. There are a good number of interesting little snippets amongst what a friend calls the 'trainspotting' aspect of science (Rutherford's stamp collecting). For example, we hear how Percival Lowell, fresh from his notorious maps of canals on the surface of Mars, also 'found' linear structures on Venus, only to be mocked by fellow astronomers. But the storytelling is overwhelmed by the detail, describing, for instance, far too frequently the details of the telescopes being used by one individual or another.

This would be a great book if you were reading up on Venus to write an article about it, and will certainly interest dedicated amateur astronomers, but it's a shame it won't appeal to a wider audience.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader. We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard. This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The Infinity Machine - Sebastian Mallaby ****

It's very quickly clear that Sebastian Mallaby is a huge Demis Hassabis fan - writing about the only child prodigy and teen genius ever who was also a nice, rounded personality. After a few chapters, though, things settle down (I'm reminded of Douglas Adams' description of the Hitchhiker's Guide to the Galaxy ) and we get a good, solid trip through the journey that gave us DeepMind, their AlphaGo and AlphaFold programs, the sudden explosion of competition on the AI front and thoughts on artificial general intelligence. Although Mallaby does occasionally still go into fan mode - reading this you would think that AlphaFold had successfully perfectly predicted the structure of every protein, where it is usually not sufficiently accurate for its results to have direct practical application - we get a real feel for the way this relatively unusual company was swiftly and successfully developed away from Silicon Valley. It's readable and gives an important understanding of...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms. On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
