Meteorite - Tim Gregory ****

There have been many books on astronomy, ranging from exploring individual aspects of the solar system, such as the Sun or Mars, through to studies of the most distant depths of the universe, but there has been relatively little on the only astronomical objects that we're able to touch (other than the Earth itself) - meteorites.

In Meteorite, Tim Gregory fills in many details of the nature of these rocks from outer space, from how they formed in the first place to the range of types and origins that are possible. Most come from the debris of the forming solar system left in the asteroid belt, but some were smashed off the Moon or Mars by an incoming impactor.

Although the main focus is the meteorites themselves (if there's any doubt, we are talking about the solid remains that fall to Earth when a meteor - a shooting star - in part survives the journey through the atmosphere), Gregory also fills us in on the contribution that meteorites have made to the Earth, whether it be bringing in minerals or causing significant events such as the extermination of the dinosaurs. We also get to meet some of the special cases - the relatively rare meteorites that have been seen falling to Earth and the surprising role that meteorites have played in helping us determine the age of the Earth and the solar system.

I have two regrets here. One is that there are no illustrations at all in the book. I would love to have seen colour plates of the dramatic sounding structures within the different types of meteorite. And the other regret is that, like it or not, once you get a meteorite down to Earth, we're dealing with a cousin of geology, and it's very difficult for geology not to become a touch dull. There are only so many types of meteorite and of crystalline structure and chemical and isotopic makeup that the ordinary reader can get through before feeling a little sleepy.

In Gregory's favour, however, his sheer enthusiasm for the subject carries the reader forward even when it feels like we are getting a bit bogged down in that geological mire of terminology and categorisation. I would recommend this book for anyone interested in astronomy but who (like me) probably hasn't given meteorites much attention in the past. They are remarkable things.

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

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

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
