Thinkonomics - Robert Johnson **

Although Thinkonomics is borderline as popular science, it claims to cover logic and critical thinking, aspects of mathematics and the scientific method respectively, so I thought I’d give it a go.

This is, without doubt, an unusual little book. In fact I’d go so far as to say I’ve never read anything like it. It’s like sitting in a pub, listening to a highly opinionated person hold out on his favourite topics of the day, from politics and sport to animal rights.

Despite the promise of insights into critical thinking and logic, what we get instead is opinions stated as if they were facts. Some of them may indeed be true, but the weakness in terms of presenting arguments in an allegedly scientific fashion is that there is very rarely data provided or any other evidence given to back up the statements.

This means that sometimes we get what feel like political stereotypes (the Conservative party is intent on selling off the National Health Service, for example) and sometimes there are evidence-free remarks that feel totally off the cuff. So, for example, when talking about physics, we are told that ‘however small you get, something else logically must make up that "thing". Atoms contain electrons, which orbit a nucleus, which is made of protons and neutrons, which are made of quarks... etc... this must go on forever, as far as we understand;’. It’s certainly news to me that electrons and quarks aren’t fundamental particles - we certainly don't understand that this goes on forever, nor is there any argument given as to why this 'must go on for ever.'

All this is supported by a writing style that feels distinctly old fogey, though as the author refers to a living grandparent, I assume he is a relatively young fogey. That isn’t helped by quite a few writing errors, the most egregious of which is probably the use of the mangled phrase ‘the proof is in the pudding.’ No it isn’t. ‘Proof’ here means ‘test’; the proof is in the eating - we test the pudding by eating it - not in the pudding.

Thinkonomics is not all bad by any means, though it certainly doesn't bear any resemblance to titles such as Freakonomics that it appears to be attempting to emulate. A book like this provides useful challenges to personal viewpoints. in some cases, the reader will probably agree with the presented opinions - for example, I thought Robert Johnson’s comments on the ludicrous nature of many Olympic sports were spot on - which gives the reader a mental pat on the back. In other cases, the opinions will run counter to the reader’s own - giving some opportunity for reflection, though due to the lack of factual backup to the arguments, there will probably be very few who are converted in their viewpoint.

Interesting, then, but I really don’t think it does what it says on the tin.

David Spiegelhalter Five Way interview

Professor Sir David Spiegelhalter FRS OBE is Emeritus Professor of Statistics in the Centre for Mathematical Sciences at the University of Cambridge. He was previously Chair of the Winton Centre for Risk and Evidence Communication and has presented the BBC4 documentaries Tails you Win: the Science of Chance, the award-winning Climate Change by Numbers. His bestselling book, The Art of Statistics , was published in March 2019. He was knighted in 2014 for services to medical statistics, was President of the Royal Statistical Society (2017-2018), and became a Non-Executive Director of the UK Statistics Authority in 2020. His latest book is The Art of Uncertainty . Why probability? because I have been fascinated by the idea of probability, and what it might be, for over 50 years. Why is the ‘P’ word missing from the title? That's a good question.  Partly so as not to make it sound like a technical book, but also because I did not want to give the impression that it was yet another book

Vector - Robyn Arianrhod ****

This is a remarkable book for the right audience (more on that in a moment), but one that's hard to classify. It's part history of science/maths, part popular maths and even has a smidgen of textbook about it, as it has more full-on mathematical content that a typical title for the general public usually has. What Robyn Arianrhod does in painstaking detail is to record the development of the concept of vectors, vector calculus and their big cousin tensors. These are mathematical tools that would become crucial for physics, not to mention more recently, for example, in the more exotic aspects of computing. Let's get the audience thing out of the way. Early on in the book we get a sentence beginning ‘You likely first learned integral calculus by…’ The assumption is very much that the reader already knows the basics of maths at least to A-level (level to start an undergraduate degree in a 'hard' science or maths) and has no problem with practical use of calculus. Altho

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
