Weighing the Soul – Len Fisher ****

Previously best know for his quirky everyday science book How to Dunk a Doughnut, Len Fisher brings together a disparate but linked set of seven areas where the challenge of beliefs has occurred in science. But this isn’t a “science challenged unfounded human beliefs” like Carl Sagan’s The Demon Haunted World. Instead it’s a case of science’s own beliefs being challenged.
The title of the book refers to the experiment in the early years of the 20th century where a doctor attempted to weigh human beings during death to see if he could see a weight loss corresponding to the departing soul (he did). But Fisher points out this man was no crank – he undertook a carefully performed experiment. It’s just that, like other observations that put scientific beliefs under stress (cold fusion, for instance) there have to be plenty of results, undertaken by different people and labs, before any sensible assessment can be made. In this case, the experiment has never been repeated, so though the doctor may have been wrong about the weight loss (and almost certainly was about the cause), it hasn’t been properly disposed of as an issue.
Fisher has an enjoyable, light style and a wonderful ability to meander into other topics that are brought up by his main theme in a way that doesn’t lose the reader, but makes the whole thing more fun. His subjects aren’t always so contentious. We get Galileo on motion, the delightfully titled “the course of lightning through a corset” on the gradual realization of what lighting was, and more. Most of the main themes are well explored in more depth in other books, but Fisher’s concentration on the challenge of scientific beliefs makes it possible to come to them fresh. The only section that disappoints a little (so it’s a pity that Fisher leaves it to last) is “what is life” that looks at the way living creatures are formed – I’m not sure why, but it doesn’t have the buzz of the other sections.
A couple of small moans – in talking about theories of light he goes straight from Newton and his corpuscles to Young as proposer of the wave theory of light, as if Huygens had never existed, which is very odd. And he repeatedly refers to light as just energy, like heat. This is a bit over simplistic, rather like saying a thrown ball “is” energy, because it imparts energy when it hits you. However these are minor concerns – it’s still a good book.

Stephen Hawking: Genius at Work - Roger Highfield ****

It is easy to suspect that a biographical book from highly-illustrated publisher Dorling Kindersley would be mostly high level fluff, so I was pleasantly surprised at the depth Roger Highfield has worked into this large-format title. Yes, we get some of the ephemera so beloved of such books, such as a whole page dedicated to Hawking's coxing blazer - but there is plenty on Hawking's scientific life and particularly on his many scientific ideas. I've read a couple of biographies of Hawking, but I still came across aspects of his lesser fields here that I didn't remember, as well as the inevitable topics, ranging from Hawking radiation to his attempts to quell the out-of-control nature of the possible string theory universes. We also get plenty of coverage of what could be classified as Hawking the celebrity, whether it be a photograph with the Obamas in the White House, his appearances on Star Trek TNG and The Big Bang Theory or representations of him in the Simpsons.

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

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
