What's Eating the Universe - Paul Davies ***

This collection of short pieces on aspects of astronomy and particularly cosmology is not bad, but didn't quite work for me. It didn't help to read the over-inflated sense of the importance of what's in here, referring to the new stuff being 'more disruptive' than anything since we moved from an Earth-centred model of the universe is, frankly, hype.

The 30 bite-size chapterettes range from 'Why is it dark at night?' and 'Where is the Centre of the Universe?' to 'Can the Universe come from Nothing?' and 'Why am I living now?' These mini-essays make the book easy to read, but the haste that is employed to get through what can be quite a meaty topic in a handful of pages means a lot of the joy of storytelling is missing. Many interesting stories in the history of astronomy and cosmology are flagged up without revealing any of the fascinating detail. So, for example, Penzias and Wilson, the discoverers of cosmic microwave background radiation aren't even named, while the infamous pigeon droppings get such a passing mention that doing so doesn't add anything to the story.

Sometimes this condensation of content is so extreme that we loose a considerable amount of accuracy. So, for example, dark matter is stated as if its existence were a known fact, with no consideration of all the problems attached to it, nor a single mention of modified gravity theories. Similarly, quantum spin is described as if it were literally a matter of particles spinning around, apart from the need to do two turns to restore the direction to the same way up. Unfortunately the folksy little openings that Davies gives to many of his mini-chapters are allowed to take up space that could have been put to good use as content.

As I mentioned at the start, this isn't a bad book and may well be of interest to someone who wants a very light touch picture of cosmology, but it could have been so much better with just a little work.

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...
