Mathematics of Life – Ian Stewart ****

Although there are a fair number of maths books by popular science writers, like our editor’s A Brief History of Infinity, or one-off books by mathematicians there are very few popular maths writers with a sizeable output. Leader of that very small pack is the highly productive Ian Stewart, mild mannered maths professor by day, popular maths writer by night.
The premise of this book is almost one of conquest. Mathematics has had a central role in most of science throughout the ages. Galileo made it clear that maths was at the heart of science. But mostly biology has avoided it. There’s no doubt which aspect of science Rutherford most had in his sights when he came up with his famous put-down ‘All science is either physics or stamp collecting.’ The fact is that for most of its life, biology has been about collecting and classifying, with very little real science involved. But of course things have changed an awful lot now – and that includes the increasing use of mathematical techniques in the science.
Oddly, Stewart is by far at his best in his introductory chapters (and parts of other chapters) where he does a whistle stop tour of the history of biology and introduces us to all the basics of the science. This might be a bit simplistic for a real biologist, but for those among us who only have a vague memory of biology from school science it is fascinating and pitched just right. And, of course, there is plenty of biology, like the human genome project, that wasn’t around when most of us were at school. Again, Stewart incisively dissects the genome project and the reason why this hasn’t transformed medicine as was promised very effectively.
What works less well is the mathematical parts. In some of his books Stewart excels at making maths interesting to the layperson, but here it is not so good. There are aspects of mathematics here, like knot theory, that only mathematicians could get excited about. And despite Stewart’s assertion that biology has entered a new era with maths at its heart, the mathematics often seemed peripheral to the science.
This is a book that’s well worth reading, particularly for the introduction to biology, but also for some of the interesting ways that maths has been used in the field (for example in deducing the ‘wiring’ required to produce the different gaits of animals) – but it would have been even better if a non-mathematician had weeded out some of the less interesting bits.

Roger Highfield - Stephen Hawking: genius at work interview

Roger Highfield OBE is the Science Director of the Science Museum Group. Roger has visiting professorships at the Department of Chemistry, UCL, and at the Dunn School, University of Oxford, is a Fellow of the Academy of Medical Sciences, and a member of the Medical Research Council and Longitude Committee. He has written or co-authored ten popular science books, including two bestsellers. His latest title is Stephen Hawking: genius at work . Why science? There are three answers to this question, depending on context: Apollo; Prime Minister Margaret Thatcher, along with the world’s worst nuclear accident at Chernobyl; and, finally, Nullius in verba . Growing up I enjoyed the sciencey side of TV programmes like Thunderbirds and The Avengers but became completely besotted when, in short trousers, I gazed up at the moon knowing that two astronauts had paid it a visit. As the Apollo programme unfolded, I became utterly obsessed. Today, more than half a century later, the moon landings are

Space Oddities - Harry Cliff *****

In this delightfully readable book, Harry Cliff takes us into the anomalies that are starting to make areas of physics seems to be nearing a paradigm shift, just as occurred in the past with relativity and quantum theory. We start with, we are introduced to some past anomalies linked to changes in viewpoint, such as the precession of Mercury (explained by general relativity, though originally blamed on an undiscovered planet near the Sun), and then move on to a few examples of apparent discoveries being wrong: the BICEP2 evidence for inflation (where the result was caused by dust, not the polarisation being studied),  the disappearance of an interesting blip in LHC results, and an apparent mistake in the manipulation of numbers that resulted in alleged discovery of dark matter particles. These are used to explain how statistics plays a part, and the significance of sigmas . We go on to explore a range of anomalies in particle physics and cosmology that may indicate either a breakdown i

Splinters of Infinity - Mark Wolverton ****

Many of us who read popular science regularly will be aware of the 'great debate' between American astronomers Harlow Shapley and Heber Curtis in 1920 over whether the universe was a single galaxy or many. Less familiar is the clash in the 1930s between American Nobel Prize winners Robert Millikan and Arthur Compton over the nature of cosmic rays. This not a book about the nature of cosmic rays as we now understand them, but rather explores this confrontation between heavyweight scientists. Millikan was the first in the fray, and often wrongly named in the press as discoverer of cosmic rays. He believed that this high energy radiation from above was made up of photons that ionised atoms in the atmosphere. One of the reasons he was determined that they should be photons was that this fitted with his thesis that the universe was in a constant state of creation: these photons, he thought, were produced in the birth of new atoms. This view seems to have been primarily driven by re
