Einstein's Masterwork: 1915 and the General Theory of Relativity - John Gribbin ****

Of the various anniversaries turning up in 2015, none is as significant to science as the development of Einstein's general theory of relativity. As the C. P. Snow quote on the back of this compact and highly readable book suggests 'If Einstein had not created the general theory (in 1915) no one else would have done so... perhaps not for generations.' The acclaimed British science writer John Gribbin is the ideal person to guide us through this key period of Einstein's life - after all he was co-author with Michael White of the less tightly focussed Einstein: a life in science.

 Because this a relatively small book (physically) it sits somewhere between a full scale scientific biography and a short introductory guide. It's quick to read, compact and highly accessible. Gribbin makes a good tutor, providing an experience that is not unlike being lectured to by a slightly pernickety but insightful and friendly professor.  (Pernickety, for instance in his careful insistence that it should always be the 'special theory of relativity', not the useful shorthand 'special relativity' (and likewise for the general theory), because it is the theory that is special/general, not the relativity.)

 If I am honest I wasn't looking forward to yet another set of biographical information on Einstein. Not long ago, a reader sent me an email commenting that he had enjoyed one of my books, but he was a bit fed up reading yet another potted biography of the great man. There seems an obligation to do it, yet when you've read a few popular science books about relativity (or gravity, or light, or quantum theory) it does seem that, like Douglas Adams' bowl of petunias, the natural response to reading about Einstein's life should be 'Oh, no, not again.' But somehow, as if by magic, Gribbin manages to make the same old personal history interesting, with real insights that show the links between the man's life and work.

 If anything, the biographical sections are a little more successful than those that concentrate on the physics. Gribbin knows his stuff (forwards, backwards and upside down), but the book's approach is just a bit too summary to give the best insight in the special theory and particularly the general theory of relativity. For instance, he gives the usual rubber sheet/trampoline with a weight analogy for matter producing a warp that bends a straight line path, but doesn't explain why this warp should cause a stationary object to start falling. The compactness means he doesn't show the actual equations of the general theory, which in compact form are beautiful and aren't difficult to be guided around, if not comprehended in detail. And he perpetuates the myth (as, I confess, I often have) that John Wheeler coined the term 'black hole.'

 This isn't, then, a book for someone who wants to get their brains entangled around the nitty gritty of Einstein's theories of relativity, but it is an excellent way to get a feel for Einstein the man, and a simple, easy to grasp overview of relativity theory - an ideal marker for this centenary year.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life.  To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

The Infinite Alphabet - Cesar Hidalgo ****

Although taking a very new approach, this book by a physicist working in economics made me nostalgic for the business books of the 1980s. More on why in a moment, but Cesar Hidalgo sets out to explain how it is knowledge - how it is developed, how it is managed and forgotten - that makes the difference between success and failure. When I worked for a corporate in the 1980s I was very taken with Tom Peters' business books such of In Search of Excellence (with Robert Waterman), which described what made it possible for some companies to thrive and become huge while others failed. (It's interesting to look back to see a balance amongst the companies Peters thought were excellent, with successes such as Walmart and Intel, and failures such as Wang and Kodak.) In a similar way, Hidalgo uses case studies of successes and failures for both businesses and countries in making effective use of knowledge to drive economic success. When I read a Tom Peters book I was inspired and fired up...

The War on Science - Lawrence Krauss (Ed.) ****

At first glance this might appear to be yet another book on how to deal with climate change deniers and the like, such as How to Talk to a Science Denier.   It is, however, a much more significant book because it addresses the way that universities, government and pressure groups have attempted to undermine the scientific process. Conceptually I would give it five stars, but it's quite heavy going because it's a collection of around 18 essays by different academics, with many going over the same ground, so there is a lot of repetition. Even so, it's an important book. There are a few well-known names here - editor Lawrence Krauss, Richard Dawkins and Steven Pinker - but also a range of scientists (with a few philosophers) explaining how science is being damaged in academia by unscientific ideas. Many of the issues apply to other disciplines as well, but this is specifically about the impact on science, and particularly important there because of the damage it has been doing...
