Anaximander and the Nature of Science - Carlo Rovelli ****

In my experience, working scientists often get history of science wrong - in this case, as it's arguably more history of philosophy, I can't say whether or not Carlo Rovelli is straying far from what's known to make his point, but what he has to say about the Greek philosopher Anaximander from the 6th century BC is fascinating.

All I really knew about Anaximander was that he had proposed an early cosmology, with a cylindrically shaped Earth and the light of the Sun and stars produced by fire contained in rings that had holes in to let the light out. This was interesting, but not necessarily hugely inspiring. By contrast, what Rovelli proposes is that Anaximander came up with a number of steps forward that were effectively foundational for the scientific method.

At first this seemed like hyperbole from someone championing a particular favourite, but by the end of the book I was convinced. What Rovelli attributes to Anaximander are the idea of a non-flat Earth floating in space - surrounded by the heavens, rather than a flat Earth with the heavens above; building on Thales' example as the first known explanation for physical processes without divine intervention; introducing the concept of natural law; and challenging his master's ideas rather than simply building on them.

The next step Rovelli takes is to try to understand why 6th century BC Greece was pretty well the only such starting point. He emphasises, for instance, that despite their impressive mathematics, astronomical observation and technological developments, Chinese philosophers and scientists never came up with the insight of a non-flat Earth floating in space, only switching to this viewpoint when they received information from missionaries in the seventeenth century. He suggests that it was the combination of having the first fully phonetic simple alphabet, the lack of dominant royalty and the independence of the city states that enabled this revolution in thinking in Miletus where Anaximander was based.

The rest of the book (about half of it) concentrates on what science is, the dangers of cultural relativism and understanding the world without gods. I found this a lot less interesting, partly because I'd seen most of it before, and partly because it is more a matter of paddling in the murky waters of philosophy of science rather than the more interesting (to me) origins of the history of science. 

For the first half alone, though, this is a book well worth having. Rovelli has improved hugely since his early super-waffly titles - if you have an interest in where science came from, this is arguably his best so far.

Rakhat-Bi Abdyssagin Five Way Interview

Rakhat-Bi Abdyssagin (born in 1999) is a distinguished composer, concert pianist, music theorist and researcher. Three of his piano CDs have been released in Germany. He started his undergraduate degree at the age of 13 in Kazakhstan, and having completed three musical doctorates in prominent Italian music institutions at the age of 20, he has mastered advanced composition techniques. In 2024 he completed a PhD in music at the University of St Andrews / Royal Conservatoire of Scotland (researching timbre-texture co-ordinate in avant- garde music), and was awarded The Silver Medal of The Worshipful Company of Musicians, London. He has held visiting affiliations at the Universities of Oxford, Cambridge and UCL, and has been lecturing and giving talks internationally since the age of 13. His latest book is Quantum Mechanics and Avant Garde Music . What links quantum physics and avant-garde music? The entire book is devoted to this question. To put it briefly, there are many different link...

Should we question science?

I was surprised recently by something Simon Singh put on X about Sabine Hossenfelder. I have huge admiration for Simon, but I also have a lot of respect for Sabine. She has written two excellent books and has been helpful to me with a number of physics queries - she also had a really interesting blog, and has now become particularly successful with her science videos. This is where I'm afraid she lost me as audience, as I find video a very unsatisfactory medium to take in information - but I know it has mass appeal. This meant I was concerned by Simon's tweet (or whatever we are supposed to call posts on X) saying 'The Problem With Sabine Hossenfelder: if you are a fan of SH... then this is worth watching.' He was referencing a video from 'Professor Dave Explains' - I'm not familiar with Professor Dave (aka Dave Farina, who apparently isn't a professor, which is perhaps a bit unfortunate for someone calling out fakes), but his videos are popular and he...

Everything is Predictable - Tom Chivers *****

There's a stereotype of computer users: Mac users are creative and cool, while PC users are businesslike and unimaginative. Less well-known is that the world of statistics has an equivalent division. Bayesians are the Mac users of the stats world, where frequentists are the PC people. This book sets out to show why Bayesians are not just cool, but also mostly right. Tom Chivers does an excellent job of giving us some historical background, then dives into two key aspects of the use of statistics. These are in science, where the standard approach is frequentist and Bayes only creeps into a few specific applications, such as the accuracy of medical tests, and in decision theory where Bayes is dominant. If this all sounds very dry and unexciting, it's quite the reverse. I admit, I love probability and statistics, and I am something of a closet Bayesian*), but Chivers' light and entertaining style means that what could have been the mathematical equivalent of debating angels on...
