Smoke and Mirrors - Gemma Milne ***

It's a bit of a strange one, this. The subtitle is 'how hype obscures the future and how to see past it'. Hype is a real problem in science communication, and I was really looking forward to an exploration of the nature of science communication hype, where it comes from, why it happens and how to correctly interpret it. Gemma Milne starts promisingly by explaining the origins of that familiar term 'smoke and mirrors'... but then it's as if you've bought a whole different book - because Smoke and Mirrors is not primarily about hype.

Don't get me wrong, hype does come into it as a linking theme, but what we really have here is a set of well thought out polemics on issues in the science and technology field, with the main thrust being on what the issues are and what might be done about them, but with a sideline in how hype can give the wrong focus and result in us addressing the wrong problems. So, for example, the first chapter is about 'finding the true meaning of value in the world of farming'. We get a lot on making farming greener and more ethical, making it more appropriate for those whom the food system currently fails, but the hype part is really just about overemphasis on things like artificial meat and how they are interesting but won't solve the problem. In 33 pages, only a couple in total are about the hype aspect.

It's not that these discussions aren't interesting. They are all topics we ought to be thinking about and Milne explores the topics well, giving a rounded picture - so, for example, in that 'feed the world' chapter, she is supportive of a sensible approach to GM rather than EU-style knee jerk opposition - but hype gets a relatively small look-in in most cases.

As one obvious example, one of the worst types of purveyor of hype are university press offices, and I had expected to get an in-depth look at these and what they do, but they aren't really mentioned, not even getting an entry in the index. Similarly, a lot of hype comes from newspaper headlines and even science magazines have a tendency to put ridiculously hyped headlines on the covers. Again, we do get a passing mention of the tabloid newspapers' obsession with cancer cures and causes, for example, but it's not the key focus of the relevant chapter.

The topics covered apart from food production are curing cancer, the future of batteries, fusion energy, space travel, quantum computing, computer-brain interfaces, AI and astrobiology. All topics worth our attention, but the way they are dealt with is more something I'd want from a magazine article on the specific subject, individually. What there is on hype wasn't enough to usefully tie them together as a book. A good piece of writing, then, but not what I was hoping for.

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
