Bad Choices - Ali Almossawi ***

At the heart of this little book is a really good concept trying to get out - for me it's what you might call a successful failure. What it's trying to do is great, and being creative about doing so is also great - but creativity goes hand in hand with frequent failure, and I'm afraid there are just too many problems here for me to love this book the way I should.

Let's get the negatives out of the way so we can focus on what's good. It's a very short but expensive book - the 144 small pages have a lot of illustration that conveys very little information. What's left is a text that I comfortably read on an hour-long train ride, yet it's being sold at near £15. The illustrations are genuinely almost all doing nothing at all except adding padding. And though Ali Almossawi's writing style is friendly and laid back, it tends to the condescending. Worst of all, the book doesn't do what it says on the tin.

The subtitle is 'how algorithms can help you think smarter and live happier', implying that this book is going to show you how to make use of algorithms to improve your life. It won't. Almost all the examples it uses (in the form of little stories that try far too hard to be quirky) are totally useless in reality. About the only practically useful one is about sorting books on a shelf (though there is better guidance on that elsewhere - see below). And yet. There is something in this book.

What it really does, if you allow it, is to open up the secrets of what's going on inside a computer - specifically in some of the algorithms used to sort and search, to do lookups with hash tables, to have linked lists that enable you to add items to the middle of an ordered set with a minimum of effort and more. There is definitely a beauty, almost a poetry to this stuff, and Almossawi is usually very good at describing it.

So, it's really not going to do what the cover claims. It won't help you with practical, every day choices and problem solving. If you want a book on practical uses of algorithms in real life, look instead at Algorithms to Live By. And those stories, I'm afraid, for me mostly got in the way rather than made the material more approachable. (Almossawi imagines the reader, when asked 'What's a binary search?' thinking 'Ah, freedom, William Wallace, Eppy Toam*, shirts on a rack.' No, we really won't do that.) But for all that there's a lovely little book on a key aspect of how computers do their jobs lurking in here. I just wish there was more content, and it wasn't so obscured by fluff.

* Yes, his characters really do have names like this.

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...
