The Big Necessity – Rose George ****

Strictly, this book shouldn’t be here at all as there’s not a lot of science in it – but taking the original, wider definition of scientia, I certainly feel that I gained a fair amount of knowledge from Rose George’s excellent book, on a subject that certainly needs more exposure than it usually gets – the essential job of dealing with human waste.

Of course there is a lot of science in the subject, but George’s book concentrates on the practical – it’s more about the engineering and sociology than the pure science. She’s at her best when describing excursions down the sewers with the men who work there, or venturing into water treatment plants.

At the heart of the book is the horrendous statistic that 2.6 billion people don’t have sanitation – not even a trench latrine – terrible because there’s no point giving access to clean water if someone can’t get away from their faeces. Equally fascinating to western eyes was the amazing story of the Japanese ‘high function’ toilet with seated seat and wash and dry features.

If I have a complaint it’s that there was a bit too much on China and Africa, and that George over-emphasizes the solids. She spends ages on the flush toilet, but hardly mentions urinals – perhaps because she hasn’t been exposed to them in all their wondrous variety. This combination of little problems means surprisingly (given she apparently wrote the book there) she doesn’t mention France, with it’s slowly dying penchant for stand-up/squat toilets, and its lack of concern about screening urinals from view. We read a lot about the lack of cubicle doors in China, but nothing about a European nation that thinks nothing of sticking a urinal unshielded on the outside of a beach building.

Even so, it’s an excellent read with surprises at every turn – or should that be in every U-bend?

Beyond Belief - Helen Pearson *****

Apparently it comes as a surprise to many that medicine was not particularly scientific until the end of the twentieth century (to be honest, it's no surprise to me - we had a GP who used homeopathy in the 90s). Instead it was based on anecdotal guidance - the kind of thing that appeared to work. Evidence-based medicine has since improved the field, trying where possible to base decisions on evidence, ideally based on randomised controlled trials. The first part of Helen Pearson's book covers this well - though I think it's by far the least interesting part of what we discover. Instead what's truly fascinating is the rest of it, looking at a wide range of other fields where evidence was rarely properly used and that are only now starting to dip a toe in the water. These include social policy, policing, conservation, business and education. The main part of the book gives us examples of how bad these areas have been in terms of basing decisions on what's always been ...

In Seach of Sea Dragons - Matthew Myerscough ****

It's common advice to would-be authors of narrative non-fiction to open with something dramatic - Matthew Myerscough certainly does this with the story of his being trapped under an avalanche on Snowdon (while his girlfriend, also carried away remains on top of the snow unhurt). It certainly is dramatic, but seemed entirely disconnected from the reason I got the book, which was to read about fossil collecting. Luckily, though, in the second chapter we get into a more conventional 'how I got interested in fossils as a boy'. Having recently reviewed Patrick Moore's autobiography and noting that astronomy was one of the few sciences where amateurs can still make a contribution, it came to mind that palaeontology is another - Myerscough is a civil engineer by trade, but just as amateur astronomers can find new details in the skies, so amateur fossil hunters have been searching for these relics for centuries. When I give talks in junior schools, the two topics that guarant...

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...
