Decoding the Heavens – Jo Marchant *****

Just occasionally, as a science writer, I come across a subject that makes me think ‘Wow, that’s brilliant, it would make a great book! I must write it.’ About five seconds later I realize that it’s so obviously a good story that someone else will have beaten me to it. And sure enough, there’s the book. In this case I did think it, Jo Marchant has written it, and the result is excellent.
The subject is not, as you might think from the title, astronomy, but the Antikythera (anti-kith-era) Mechanism. Even that name is redolent with excitement – it’s like something Indiana Jones or Lara Croft might search for – and there were certainly some interesting characters involved in its decoding. Even Arthur C. Clarke and Richard Feynman were fascinated by this ancient puzzle. The Mechanism is a device found in 1900 amongst the wreckage of a Greek ship from the first century BC. It’s a complex geared structure, built hundreds of years before anyone knew such gearing was used.
Without giving too much away, the device has proved neither a clock nor an astrolabe (two of the early ideas) but a calculator that predicted the motion of bodies in the solar system and even seems to have acted as a combined calendar and Greek games locator. It was, in essence, an early computer – not a programmable computer, but one specifically designed around astronomical data. Marchant weaves an elegant tale of the gradual uncovering of the Mechanism’s function, drawing in many associated developments, from the use of diving equipment to the use of X-rays in uncovering details of the hidden mechanism.
If I have one slight complaint it’s that Marchant likes starting a chapter with a historical dramatization and this doesn’t always work. For instance, the first couple of pages of chapter 3 begin with a description of a historical ship setting sail. But we’ve already been introduced to the Mechanism, and I wanted to get on with that. Okay, this turns out to be a description of the ship the Mechanism was sunk with , but continuity was shattered. She also has a confusing tendency to switch in and out of the historical present tense mid-paragraph.
That’s a minor moan, though. It’s a wonderful subject and an entrancing book. Recommended.

Phenomena - Camille Juzeau and the Shelf Studio ****

I am always a bit suspicious of books that are highly illustrated or claim to cover 'almost everything' - and in one sense this is clearly hyperbole. But I enjoyed Phenomena far more than I thought I would. The idea is to cover 125 topics with infographics. On the internet these tend to be long pages with lots of numbers and supposedly interesting factoids. Thankfully, here the term is used in a more eclectic fashion. Each topic gets a large (circa A4) page (a few get two) with a couple of paragraphs of text and a chunky graphic. Sometimes these do consist of many small parts - for example 'the limits of the human body' features nine graphs - three on sporting achievements, three on biometrics (e.g. height by date of birth) and three rather random items (GNP per person, agricultural yields of various crops and consumption of coal). Others have a single illustration, such as a map of the sewers of Paris. (Because, why wouldn't you want to see that?) Just those two s...

The Bright Side - Sumit Paul-Choudhury ***

When I first saw The Bright Side (the subtitle doesn't help), I was worried it was a self-help manual, a format that rarely contains good science. In reality, Sumit Paul-Choudhury does not give us a checklist for becoming an optimist or anything similar - and there is a fair amount of science content. But to be honest, I didn't get on very well with this book. What Paul-Choudhury sets out to do is to both identify what optimism is and to assess its place in a world where we are beset with big problems such as climate change (which he goes into in some detail) that some activists position as an existential threat. This is all done in a friendly, approachable fashion. In that sense it's a classic pop-psychology title. For me, Paul-Choudhury certainly has it right about the lack of logic of extreme doom-mongers, such as Extinction Rebellion and teenage climate protestors, and his assessment of the nature of optimism seems very reasonable, if presented at a fairly overview leve...
