The Perfect Shape: Spiral Stories - Øyvind Hammer

At first sight, a book with 53 chapters all about spirals from a mathematical viewpoint sounds up there with watching paint dry in the entertainment stakes. However, there is no need for those who don't find Euclid an entertaining holiday read to turn away - because Øyvind Hammer uses the concept of a spiral as a jumping off point to cover everything from architecture to biology, from tiling to toilet paper. That word 'stories' in the title is really important. Unlike some academics, Hammer really understands the importance of narrative in getting science across.

The mathematical aspect is always lurking in the background, and Hammer is not afraid to bring in equations regularly, but to be honest, you can read the book and still enjoy it while ignoring all the maths and entirely failing to remember the difference between a logarithmic, hyperbolic or Archimedes spiral, let alone a lituus (which my spellchecker thinks should be a litmus). 

What makes the book a genuinely enjoyable read is the way that Hammer meanders around so many bits of contextual background, whether we are being stunned by the impossible looking Malwiya minaret in Samarra, Iraq (a conical helix) or marvelling at the fossilised handiwork of the 'daemon beavers of Nebraska', looking for all the world like a 3 metre high stone drill bit. The clear colour illustrations really help, as does Hammer's tongue-in-cheek, chatty style.

I'll be honest, there are one or two chapters that feel a little samey - it's almost inevitable with 53 of them, varying from a couple of pages to quite lengthy sections (on mollusc shells, for instance). It's the sort of book where you shouldn't feel guilty about skipping a page or two if it isn't really your thing, as something new and wonderful will be along soon. I also found the lack of flow between the chapters made the book feel fragmented. But on the other hand it also made it good for dipping into.

I always think a good measure of the 'wow factor' of a book is whether you can resist reading out a bit (or showing a picture) to someone nearby. I certainly couldn't. This isn't a book for absolute everyone - if maths and the natural world really turn you off, it won't work for you. But otherwise, Hammer has achieved the seemingly impossible, in making spirals (and helixes) a fun topic. It's even relatively cheap for a good hardback (a rarity from an academic publisher).

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...
