The Age of Scurvy – Stephen R. Bown ****

We all know that scurvy was an unpleasant affliction, that particularly hit sailors in the 16th to 18th centuries, but it’s hard to be prepared for the sheer horror of this blight of the seas as presented graphically in Stephen Bown’s often gripping history of the disease and its cure.
Not only does Bown gives a vivid picture of the horrible nature of the disease itself, from rotting gums to the joints in old broken bones re-opening, but perhaps the biggest shock is the inhuman approach the authorities of the time took to seamen. We hear of Admiral Anson’s voyage in the 1740s where the crew of over 2,000 men on a flotilla of six ships was reduced to more like 200 on their return, largely by the impact of scurvy. In itself this was horrible, but at the time Anson set sail there were a shortage of able seamen – the solution? Just drag the elderly invalids from the Chelsea Hospital (for retired injured servicemen) and throw them on board. The practice at the time was to carry up to half as many men again as were required, on the assumption that a sizeable percentage would die en route.
These ships, Bown tells us, were riddled with disease. The food started off bad, and ended up inedible – the best tasting thing in the ship’s hold after a few months at sea were the rats. And though it was recognized what a cost scurvy presented to the navy (after all, if enough men died, the fleet might lose a valuable warship), the attempts at curing it were initially pitiful.
Bown leads us through some of the biggest scurvy disasters, the early attempts at curing it and the painful realization of what was required to prevent it. Along the way we meet characters like James Cook, and his unrivalled scurvy-free voyages, and see how Britain’s final realization of how to get scurvy under control influenced the aquatic defeat of Napoleon.
One of the most interesting reflections is the way that individuals realized that the fresh fruit and vegetables, and citrus juices, were helping, but the majority of “experts” didn’t notice, happier to go for odd (and non-functioning) cures like sea water, mostly because they were cheap and practical. There was even an early clinical trial in the 1700s, but the outcome was ignored. (To be fair, like many early attempts at science, it wasn’t a very good trial – see John Waller’s Leaps in the Dark for details of the flaws in early scientific experiments like this.) Time and time again it seems to us it should have been obvious to everyone what to do – but no, off they went again on some other peculiar and useless attempt.
Mostly Bown’s book is very readable, and brings the atmosphere of the time on ship alive in a way that can almost be cut with a knife. The only fault is a tendency to repeat the symptoms more than is needed – and a first few chapters before he settles into storytelling where he tells us once or twice what he’s then about to tell us again – but that’s bearable. In the end it’s the people and the story of the final realization of what’s happening, of a tiny outbreak of science in what had been a matter of habit and guesswork, that leads to Bown’s subtitle “How a Surgeon, a Mariner and a Gentleman helped Britain win the Battle of Trafalgar” – and when he’s showing us those people in action, Bown does a great job.

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...
