Eureka! The Birth of Science – Andrew Gregory *****

“Oh, no, not the ancient Greeks? Yawn, yawn, what a bore.” If this is your natural reaction to a book on the ancient Greek origins of science, hold on there. It’s easy enough to think of the Greeks as a bit of a bore because they tended to be long winded and philosophising (and they foisted geometry on us, for goodness sake) – but the fact is that their work, mostly wrong though it may be, is the foundation of all of science.

What’s more, Andrew Gregory makes the whole business interesting, without resorting to any fancy literary tricks – it’s a straightforward historical tour of the Greek prehistory of science that is simply bursting with insight. If you’ve ever wondered why it was such a big deal that Galileo and others should suggest that the Earth wasn’t at the centre of things, here is part of the explanation. It’s not just a matter of selfish assumption, but the entire Aristotelian physics depended on it. Without the Earth at the centre of things, his equivalent of gravity simply wouldn’t work.

Because so much of the actual detail is wrong, it’s also easy to dismiss the ancient Greeks’ input to science – but, as Gregory emphasizes, it was a huge leap to move from the assumption that the cause of natural events and objects was mythological and down to the intervention of gods, to a rule-based cosmos where it was possible to deduce a logical explanation for events. He contrasts, for instance, the Babylonians and Egyptians, who achieved great technological feats, and were quite capable of recording and predicting natural events, but who resolutely put the explanation of why down to supernatural intervention, and who consistently resorted to inconsistent myth to explain how the cause was working.

Some would argue that Gregory has been a little premature – that the ancient Greeks weren’t so much the earliest part of the history of science, but the prehistory of science. To make this distinction, what the Greeks did is often called natural philosophy, based on observation and argument, as opposed to science, based on observation, experiment and the development and refinement of theory from those observations and experiments. So it’s worth taking a look at least three other books that ascribe the birth of science to later midwifes:

Medieval friar Roger Bacon in my Roger Bacon: The First Scientist
Leonardo da Vinci in Michael White’s Leonardo, and
Galileo in John Gribbin’s Science: A History

but even they would agree with Gregory how significant the ancient Greeks foundations are, and the great thing is to get a very effective grounding in these Greek ideas in a single, compact and enjoyable book. Nice one.

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...
