The Ashtray - Errol Morris *****

Wow. When someone suggested I read a book called The Ashtray, written by a documentary film-maker, it didn't strike me that it would be a book that gave deep insights into the history and philosophy of science - while also being a remarkable reading experience. In fact, I almost didn't bother with it, but I'm glad that I did.

The titular ashtray was thrown at the author when he was a grad student - thrown by one of the two best known names in the philosophy of science, Thomas Kuhn, he of The Structure of Scientific Revolutions and the concept of paradigm shifts. Kuhn didn't like the young Errol Morris daring to challenge his ideas and reacted with what some would regard as a less than philosophical reply by hurling a heavy glass ashtray at him.

Part of the reason that reading The Ashtray is a remarkable experience is because it's a book that feels in some ways like watching a documentary. I have to confess I've never seen any of Morris's work, but he uses visual imagery both to make his point and to be playful. I don't usually like semi-coffee table format books, but this was a delight to read. Even the copious marginal notes (more stylish than footnotes) have a little edge as the inline reference numbers are elegantly shaded red. (Also one of the margin notes quotes me, so what's not to like?)

My position on Kuhn's work is primarily ignorance. As a science writer, my interest in history of science is to give context and narrative structure to explaining aspects of science - and I tend not to think of philosophy of science much at all, except to make the point that science isn't about finding 'the truth', but is about our best theories given the current data. I've never read Kuhn's book, and all I had assumed it covered was the idea of having sudden shifts of scientific viewpoint - effectively the philosophy of science equivalent of catastrophism (as opposed to gradualism) in geology. What I hadn't realised was that Kuhn's ideas are thoroughly embedded in post-modernist woo.

I ought to emphasise that my only exposure to Kuhn is via The Ashtray, and Morris clearly detests Kuhn's ideas - but assuming Morris is telling it straight, it's hard to understand why Kuhn is even mentioned anymore, unless, like me, most people who do so aren't aware that he wasn't just talking about sudden shifts in scientific viewpoints, but that a) he thought this meant the world itself was changed, because there is no reality, only the words we use to describe it, b) progress in science is a meaningless concept and c) we can't really say anything about, say Newton, because when he used words, he didn't mean the same thing as we do by those words. His 'gravity' is not our 'gravity'. (I may be a little adrift in the subtle detail in that whirlwind summary, but that seems to be the message.)

I'd honestly thought that history and philosophy of science had pretty much abandoned  post-modernism after the Sokal hoax and the realisation that it seemed far more about its advocates pretensions than having anything useful to say about science, so it was a revelation to me that Kuhn was a full-blown advocate of this approach.

Bearing in mind Morris is dealing with an approach to philosophy where it's almost impossible to discern meaning and unless words like 'hermeneutics' and 'exegesis' are part of your everyday vocabulary it's easy to get lost, his explanations are almost all easy to follow. There were a couple of pages near the middle where my eyes did start to glaze over, but Morris was soon back to form.

In the end, this is still a very odd book. It's an anti-love letter to Kuhn, a powerful introduction to one aspect of history and philosophy of science and a dramatic dismantling of a horror that has loomed over science and scientists like a Frankenstein's monster since the 60s. I loved it.

Beyond Weird - Philip Ball *****

It would be easy to think 'Surely we don't need another book on quantum physics.' There are loads of them. Anyone should be happy with The Quantum Age on applications and the basics, Cracking Quantum Physics for an illustrated introduction or In Search of Schrödinger's Cat for classic history of science coverage. Don't be fooled, though - because in Beyond Weird, Philip Ball has done something rare in my experience until Quantum Sense and Nonsense came along. It makes an attempt not to describe quantum physics, but to explain why it is the way it is.

Historically this has rarely happened. It's true that physicists have come up with various interpretations of quantum physics, but these are designed as technical mechanisms to bridge the gap between theory and the world as we see it, rather than explanations that would make sense to the ordinary reader.

Ball does not ignore the interpretations, though he clearly isn't happy with any of them. He seems to come clo…

The AI Delusion - Gary Smith *****

This is a very important little book ('little' isn't derogatory - it's just quite short and in a small format) - it gets to the heart of the problem with applying artificial intelligence techniques to large amounts of data and thinking that somehow this will result in wisdom.

Gary Smith as an economics professor who teaches statistics, understands numbers and, despite being a self-confessed computer addict, is well aware of the limitations of computer algorithms and big data. What he makes clear here is that we forget at our peril that computers do not understand the data that they process, and as a result are very susceptible to GIGO - garbage in, garbage out. Yet we are increasingly dependent on computer-made decisions coming out of black box algorithms which mine vast quantities of data to find correlations and use these to make predictions. What's wrong with this? We don't know how the algorithms are making their predictions - and the algorithms don't kn…

Five Photons - James Geach ****

It is generally acknowledged that Stephen Hawking's A Brief History of Time is one of the most common books to be bought but not read beyond the first few pages. If you are the kind of popular science reader who found Hawking hard going, you can stop now - Five Photons is not for you. If, on the other hand, you found A Brief History of Time a piece of cake and wished you could get into more depth without resorting to heavy mathematics or a tedious textbook style, Five Photons could be just up your street.

Astrophysicist James Geach starts of fairly gently with a chapter on the nature of light that mostly sets aside quantum physics, leading up to the observation that light is our vehicle for for stripping back the history of the universe to its earliest times (or, at least, the point where the universe became transparent). From here on, the five photons of the title take us on different journeys, from the oldest surviving light of the cosmic microwave background radiation to that fr…
