Mage Merlin's Unsolved Mathematical Mysteries - Satyan Linus Devadoss & Matthew Harvey **

The authors of Mage Merlin's Unsolved Mathematical Mysteries don't seem to quite know who it was written for. The title and the general theming around Arthurian legend pitches it at an audience of children, maybe even young teenagers. However, the content is anything but aimed at that audience.

The book is a collection of unsolved maths problems very loosely fitted to the idea of it being a collection of questions asked of the great wizard Merlin. From such a description, or a flick through the pages, you might think that this is some kind of puzzle book for you to solve, but this isn't the case. Rather, it's a collection of relatively mundane (if esoteric) questions which despite the efforts of hundreds of years of professional mathematics we still haven't solved. With sixteen mysteries in all there is a wide selection of different kinds of problems.

For example the first question is: 'Can you cover a 201x201 meter square using six 100x100 meter squares (without cutting anything up)?' The answer to this and all of the other 'mysteries' the book poses is, 'We don't know.' It might be possible but nobody has managed to figure out a mathematical proof for it. Knowing that this is the case from the start as the book rather take the fun out of reading a new mystery.

In reading this book, it feels like it has no real audience.The Arthurian dressing feels completely perfunctory as anyone that it appeals to would almost certainly have no interest in the underlying mathematics. Additionally if you are somebody to whom such mathematical problems are of great interest the information is generally sparse and it's buried under what is essentially an annoying and unnecessary framing device.

It is worth noting that the images which make up much of the book are well designed and are used effectively to communicate what can be relatively complex puzzles to get your head around.

Overall the book looks great but feels designed for a much younger audience than its content. Whilst it offers simple to understand explanations of a number of well known unsolved mathematics problems, those looking for that kind of thing would likely do much better elsewhere.

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
