Dinosaurs Rediscovered - Michael Benton ****

When I give talks about science in junior schools, there is one magic word that I only have to mention to get children's attention: dinosaurs. They have a fascination that may dim a little with age, but still stays with us, whether it's their dramatic side (as brought out in the Jurassic Park films) or the fascination of finding out more about a set of animals that once dominated the Earth.

Mention of Jurassic Park tends to produce grinding of teeth amongst professionals in the field - leaving aside the impossibility of the premise (thanks to the half-life of DNA, amongst other things), our understanding of what dinosaurs looked like, how they moved and lived - and far more - has transformed immensely in last 30 or so years - and yet the representations we see on the screen often hark back to an earlier vision.

Michael Benton eases us in with a chatty introduction about how science works and how we now think we know far more about the dinosaurs than was possible even ten years ago, revealing aspects such as skin pigmentation, feathers, what their biting capability was like and far more through fascinating new techniques and discoveries.

This is literally a weighty tome - at nearly 1kg I found it quite hard to hold to read for any sustained period. For me, the mix of content sometimes lacked a sense of structure and flow - we go from sort of dinosaur top trumps inserts with illustrations, specifications and a 'little-known fact' about each species, to background on their period, stories of discoveries and answers to perky little questions such as 'Were the dinosaurs warm blooded?' (short answer 'Yes and no') and 'Are birds really dinosaurs?' (short answer 'Yes'). Then we'll plunge into something quite detailed, such as bone histology, the study of the internal microscopic structure of bones.

Overall the book is often charming, verging occasionally on the whimsical (particularly in photograph captions: of a portrait of Thomas Henry Huxley, for example, we read 'did he perhaps know how smart he was'). I found it difficult to read through from end to end, finding it worked better as something to dip into on train journeys... but well worth it for a journey that was both informative and personal.

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...
