Ten Questions Science Can’t Answer (Yet) – Michael Hanlon *****

At first glance, a book of questions that science can’t answer is a pretty dull read. Questions alone aren’t enough – we need answers as well. Yet Michael Hanlon makes this topic a voyage of discovery into the unknown. Once you get started, it’s hard to put it down.
Each of the first eight topics (yes, I know there are ten – I’ll come back to this) is a surprising and engaging excursion into a subject that you may not have thought about before, but you certainly will be thinking about once you’ve read the book. It starts with the exploration of whether or not animals are conscious. Next up is the whole matter of time – a strange phenomenon, once you start to think about it. Then after a section on aging and whether we can live forever comes one of the big surprises – a fascinating discussion entitled “what are we going to do with the stupid.” Hanlon points out that where in past centuries we used to happily mock the disabled, or those of different race, now it’s only politically correct to mock those who are at the low end of normal intelligence. That, he argues, is the reason reality TV shows are so popular. And with the job market constantly changing, with less and less “brute force” and more “brain” jobs, there is a real issue of how to give everyone the best chances – a really thought provoking section.
From there he goes on to dark matter and dark energy, life in the universe, whether we remain the same person when every cell in our body changes, and the widespread nature of obesity and fatness, which proves under his scrutiny much less straightforward than you might think.
The only let down is the last two chapters. The ninth is entitled “can we really be sure the paranormal is bunkum”, which sounded very promising, but Hanlon changes from a rather laid back style to downright aggressive here, and it’s both a little unpleasant and confusing. The confusion arises out of a mixed message – in one breath he’s saying “everything paranormal (including organized religion) is rubbish” and in another “though it’s mostly rubbish, there are elements that could be worth investigating.” The unpleasantness comes from the vigour with which he puts down the supernatural. Despite statistics to the contrary, Hanlon suggests that most rational people consider all supernatural concerns (including religious beliefs) to be “gibberish”. Clearly this is historically untrue, and arguably is also untrue of the present day world. He even contradicts himself, saying later in the piece that a 1979 survey found that the majority of American professors surveyed were prepared to accept that ESP was a possibility worth studying.
He makes matters worse in his attack on “intercessory prayer.” Now I have to confess I don’t believe in that praying over someone results in a supernatural intervention to make them better, but I still have problems with his remark “It never seems to be the case, puzzlingly, that the volunteers are asked to pray for a worsening of the patients’ condition…” Setting aside whether or not intercession for harming might work, if you translate this question into a medical equivalent, it’s a bit like asking why conventional medical trials don’t attempt to give intentional overdoses to see how badly the patients are hurt. It just doesn’t quite make sense.
The tenth chapter, which is a brief exploration of how we can be sure anything is real hasn’t got the same problems, it’s just a touch flimsy. Despite my concerns about chapter nine, though, I still have no doubts in awarding this book five stars – it’s well worth it for those first eight, thought provoking and fascinating chapters.

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
