Cosmology for the Curious - Delia Perlov and Alex Vilenkin ***

In the recently published The Little Book of Black Holes we saw what I thought was pretty much impossible - a good, next level, general audience science title, spanning the gap between a typical popular science book and an introductory textbook, but very much in the style of popular science. Cosmology for the Curious does something similar, but coming from the other direction. This is an introductory textbook, intended for first year physics students, with familiar textbook features like questions to answer at the end of each chapter. Yet by incorporating some history and context, plus taking a more relaxed style in the writing, it's certainly more approachable than a typical textbook.

The first main section, The Big Bang and the Observable Universe not only covers basic big bang cosmology but fills in the basics of special and general relativity, Hubble's law, dark matter, dark energy and more. We then move onto the more speculative (this is cosmology, after all) aspects, bringing in inflation (surely more doubted than ever before at the moment), string theory, whether the universe had a beginning and whether it's possible to create a universe from nothing. There's even a subsection labelled 'A proof of God?' where, not surprisingly, that 'universe from nothing' idea is used to counter what is hardly a rigorous 'proof' in the first place.

Being a textbook lite, although there are a fair number of equations, there is relatively little manipulation of them - certainly not enough to lose a dedicated reader with a good grasp of high school maths. The ideal market for this book is either someone who has read popular science titles on the big bang and wants to get more depth, or a student about to start on a physics course at university who wants to make it more comfortable to ease into the course. 

Delia Perlov and Alex Vilenkin should be congratulated on making a big step towards accessibility in a book like this. (Incidentally, don't go for the Kindle version - it's ludicrously expensive, and this is the kind of book where you benefit from having the physical version.)

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. Ha

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
