The Last Days of Smallpox - Mark Pallen ****

It's very rare that I find a medical popular science book unputdownable (in fact it's my least favourite sub-genre of popular science) - but it's an adjective I'd apply to Mark Pallen's The Last Days of Smallpox. This horrible disease was eradicated worldwide in 1977 - and a story of its background, including the last natural outbreaks in the UK, makes up the opening section of this book, but the main focus is an exploration of the last ever outbreak in the UK in Birmingham in 1978 - one year after the disease was eradicated.

Pallen takes us through in immaculate detail the escape of smallpox from a lab at Birmingham University, the sad cases of Janet Parker, a photographer who worked in the same building and died of smallpox, and Henry Bedson, the microbiologist in charge of the lab who committed suicide as a result of the stress of the outbreak. Pallen covers the possible ways that Parker could have become infected and gives a blow-by-blow account of the court case when the Health and Safety Executive took the University to court over the outbreak.

All of this could have been rather dull, despite the gruesome topic. However, Pallen has a gift for dramatisation and the account, often in the present tense, gives a sense of urgency and reality to the narrative, in a way that I've rarely seen in a science book. A few years ago I was taken on a tour of Porton Down to record a radio programme and remember the stomach churning frisson of looking through glass at people handling deadly diseases. I was taken straight back to that corridor and the feeling of tension I felt there by Pallen's excellent descriptive writing.

The book is self-published, but has been proof read and copy edited well. It only really shows in the print size, which is smaller than I would have liked. A publisher might have tightened up a few parts, notably the account of the court case, which perhaps went into a little too much detail, but if you like legal stories (which I do), it was no problem.

The combination of the account of the defeat of the deadly virus that inspired the process of vaccination with the particular and very human happenings at Birmingham in 1978 makes this book a real winner.

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...
