Timeswitch (SF) - John Gribbin *****

This is one of the best science fiction books I've read in ages - it could have been written for me, combining as it does hard science, an element of historical fiction and some mind-boggling twists. It even nearly achieves something that had seemed impossible.

John Gribbin is one of the UK's top writers of popular science books, but he proves here that he can put his hand to fiction writing with masterful ease. In Timeswitch, a device is discovered under Stonehenge that provides a wormhole style portal into the past. But it can only achieve jumps in units of 300 years, and the further back you go, the less time you have in the place you visit before you are dragged back to the present. The book's present is an alternative world, where scientific discoveries were made much earlier than in our reality (Galileo comes up with special relativity, for instance), as a result of which we were hit by global warming much earlier and the present is almost uninhabitable. The scientists working on the portal try to use it to change the past and save the environment with fascinating consequences.

There were so many things I liked here. It was well written and kept me pushing on to discover more. The way Gribbin handles the possibility that changing the past might result in different futures and hence different versions of the time travellers is brilliant - reminiscent of the multi-layered delights of one of my favourite films, Inception (this would make a great movie or TV series). The historical periods are well conceived and I was impressed with way the author plays with the different people in the past to construct a new history of science.

That's where the 'nearly achieves something that had seemed impossible' comes in. I have always thought that it should be possible to write a good piece of fiction that also gets across some real science in an effective way. This is by far the best book I've ever seen for doing this - with the only problem that the terminology used is not the ones we use, and the historical context, so important in popular science, is here all fictional.

However, this doesn't stop the book being a superb piece of science fiction (with historical fiction touches). And even when you think you can see what's coming, there's a clever twist that changes things entirely. If I have any complaint it's only that I suspect in a real alternative history like this far fewer of the familiar names would crop up in science, because modern physics has got so mathematical that most of great physicists in history simply couldn't handle it. I'm thinking particularly of Cavendish, who is given an important place in developing advanced physics, but as far as I'm aware had no mathematical ability. It's a minor niggle that wouldn't bother anyone who wasn't a popular science or history of science nerd.

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
