In a Flight of Starlings - Giorgio Parisi ***

This is very much an attempt to emulate Carlo Rovelli's success with short books containing seven or eight essays, beginning with Seven Brief Lessons in Physics. In this case, Italian Nobel Prize winning physicist Giorgio Parisi gives us a set of eight unconnected essays, some solidly scientific, such as the opening one on how his team studied starling murmurations, others more philosophical or memoir-like, such as his account of ‘physics in Rome around fifty years ago’. 

I personally couldn’t see a lot of interest in the less scientific essays, but the detail of his work on starlings was very interesting - I had read about various computer models of murmurations but had no idea how actual flocks were studied, and Parisi gives us a good account of the methods used. Some of the other essays with a strong science content are a lot less engaging, though, because Parisi (or his translator) really doesn’t know how to describe topics like the particle physics of the 1970s in a way that is accessible to a general reader, merrily throwing in comments like ‘All that was left was to study the Yang-Mills theories in order to understand the sign of the beta function: a negative would be an unexpected result with profound consequences for physics,’ with no unpacking of the terminology.

I didn’t really understand the preface which attempts to justify the book's existence. It says that events such as Covid and climate change mean ordinary people have to trust science and understand how scientists work, so I’m going to tell you about my work. There’s a logical disconnect here: his work may well be genuinely interesting, but it is not going to convince a single sceptic to accept vaccines or the need to take action on climate change.

Either as a result of too literal a translation, or the original being written more like a (bad) academic paper, there are some horribly clumsy sentences. Take the opening of the first chapter: ‘The question of interaction is a crucial one in many areas, including for the purposes of understanding certain psychological, social and economic phenomena. The work described in this essay focuses on how each member of a flock of birds is able to communicate in order to move in a coherent way, producing a single entity that is at once collective and multiform.’ It could be the abstract of a paper. Was there no editor involved? I’ve seen better writing in high school essays.

Overall, then, not an addition to the list of excellent short science books that really get a topic across to the general reader. It is possible to write such books that really hit the spot. Take, for example, Jim Al-Khalili's The World According to Physics or John Gribbin's Six Impossible Things. But this one certainly doesn't.

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

The Genetic Book of the Dead: Richard Dawkins ****

When someone came up with the title for this book they were probably thinking deep cultural echoes - I suspect I'm not the only Robert Rankin fan in whom it raised a smile instead, thinking of The Suburban Book of the Dead . That aside, this is a glossy and engaging book showing how physical makeup (phenotype), behaviour and more tell us about the past, with the messenger being (inevitably, this being Richard Dawkins) the genes. Worthy of comment straight away are the illustrations - this is one of the best illustrated science books I've ever come across. Generally illustrations are either an afterthought, or the book is heavily illustrated and the text is really just an accompaniment to the pictures. Here the full colour images tie in directly to the text. They are not asides, but are 'read' with the text by placing them strategically so the picture is directly with the text that refers to it. Many are photographs, though some are effective paintings by Jana Lenzová. T

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
