Beware Invisible Cows – Andy Martin ***

This is a remarkable book, taking a very original approach to popular science that has the potential to be great – and an equal potential to be dire. It’s what I’d define as the first Impressionist popular science book (with the possible exception of the disastrous Everything and More by David Foster Wallace).
Just as the Impressionists in the art world moved away from a literal and accurate reflection of what was seen, instead trying to portray the impact of the visual on the senses, Andy Martin’s meandering book is much more about how the science he discovers along the way in his attempt to search for ‘the source of the universe’ impacts him, than about the science itself.
The result has mixed value. Martin visits locations like the Keck Observatory on Mauna Kea in Hawaii and the LIGO gravitational wave observatory in Washington state – and there gives us a sub-Bill Bryson guided tour and interaction with some of the scientists he meets, and this can be quite interesting. It just hadn’t occurred to me that at 14,000 feet, working on the Keck Observatory means dealing with altitude problems (though most of the scientists work from remote stations without the need to undergo the rigours of high altitude). But at other times, Martin rambles on about things that really are of no interest.
Occasionally he seems not to get the point. This is most obvious when he refers to the reflection in a mirror. He goes on (and on) and about left and right being reversed. ‘This is the inescapable law of left-right reversal, built into the very process of reflection,’ he says. Well, no, it isn’t. Just a moment’s thought would show that there is nothing about reflection that inherently requires a left-right reversal (as opposed to top-bottom, for example). What in fact happens in a mirror is back-front reversal. It turns things inside out like a rubber mould. It’s just our interpretation of what is front and back, left and right, that makes us interpret the image the way we do.
There’s also some pretty ropy stuff about quantum entanglement, where we get the impression that his physicist brother is attempting to build an instantaneous communicator, only after the failure of which does he realize it’s not possible. Sadly this has been common knowledge in the field for a long time – the whole story feels like a myth. (For a more effective investigation of entanglement, see my book The God Effect.)
Overall, I found Beware Invisible Cows frustrating and often verging on the unreadable. The problem with interpreting the science through Andy Martin’s life is you have to be interested in Andy Martin – and I’m not. From my own viewpoint, I couldn’t give the book more than a two star rating, but I’ve actually rated it three as I believe that some people will enjoy the florid writing style and the endless deviations into personal history.
It’s a novel, and interesting attempt – but it’s not for me.

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...
