The Trouble with Physics – Lee Smolin *****

This is the second book I have read recently which seeks to deconstruct string theory, and put in to question its validity as a scientific theory. (The other one is the more mathematical and technical Not Even Wrong by Peter Woit.) Smolin describes string theory in a very deft and readable fashion, but the real strength of the book is Smolin’s reflections on the flaws in the reasoning behind string theory, and how the way that the physics community works has helped to elevate string theory to the point where it is seen as a panacea to all of the big issues that remain for physicists to try to answer.

Smolin successfully argues the point that we need to reassess our understanding of space and time if we are ever to come up with a ‘theory of everything’, which string theory purports to be. As the author points out, if physicists are to do this then we need to encourage ‘seers’ (Smolin’s term), like Einstein, Bohr, Heisenberg, etc. who have the brilliance of thought to be able to understand the Universe at its most fundamental level and will not be caught up in the flow of current trends in physics which most physicists find themselves being swept along with. One of the reasons that Smolin wrote this book was to encourage his fellow physicists to start to think outside the limiting constraints of string theory, and the stranglehold it has on the physics community, effectively stifling any ideas or theories that are counter to it. The author illustrates very effectively how string theory has made physics go round in circles since the early 1980s, making no real progress at all.

It is a superb and absorbing read, it may be a little heavy going in places if you’re coming to string theory with no knowledge at all of what is about. There are several other books that describe string theory for the layman in a more accessible fashion. It could also be more comprehensively illustrated, but nonetheless this is a book I would highly recommend. An extremely readable and highly thought provoking work.

Rockets and Rayguns - Andrew May ****

The Cold War period saw dramatic developments in science and technology, coinciding with the flourishing of the science fiction genre. In Rockets and Rayguns, Andrew May draws on the parallels between reality and fiction, each influencing the other.

Inevitably a major Cold War theme was the threat of nuclear war, and May opens with the bomb. It's fascinating that fiction got there first - nuclear weapons were featured in science fiction when many physicists were still doubting the practicality of using nuclear energy. Of course, it's a lot easier to simply take a concept and dream up a weapon than it is to make it for real - for example, H. G. Wells' prophetic nuclear bombs from his 1914 The World Set Free were nothing like the real thing. And some science fiction devices concepts - notably ray guns and force fields - came to very little in reality. However this doesn't prevent the parallels being of interest.

May gives us a mix of the science - describing how nuclear we…

Galileo Galilei, the Tuscan Artist – Pietro Greco ****

Near the beginning of John Milton’s epic poem Paradise Lost, he refers to a ‘Tuscan artist’ viewing the Moon through an optic glass. He’s talking about Galileo – one of history’s greatest scientists, but not the most obvious person to slap an ‘artist’ label on. Yet Galileo lived at a time – the Renaissance – when it was fashionable to dabble impartially in both the arts and sciences. Look up ‘Renaissance man’ on Wikipedia and you’ll see Galileo’s picture right there underneath Leonardo da Vinci’s. It’s a less well-known side to his life, but it crops up again and again – interspersed among his many scientific achievements – in this excellent new biography by Pietro Greco.

If you’re looking for interesting trivia, you’ll find plenty in this book. Galileo’s father was a musician with scientific leanings, who carried out some of the first experiments on musical acoustics – which Galileo may have assisted with. As a young professor of mathematics, Galileo delivered a couple of lectures on …

Meet Your Bacteria - Nicola Temple and Catherine Whitlock ***

There have been a good number of books on our microbiome - the bacteria and other tiny organisms living in our body - from The Wild Life of Our Bodies throughI, Superorganism to I Contain Multitudes. Each of these is a traditional popular science book format, and all, to some degree, suffer from the same problem - in part, they have a tendency to present collections of facts, little more than bullet points of information strung together, rather than providing an effective narrative. As Meet Your Bacteria is in a significantly different format, there was a chance to imbue the subject with more dynamism and interest.'

When I first looked at the book, I assumed from its shape and cover that it would be in the style of highly illustrated, two-page spreads with large illustrations and the text little more than captions. In reality, Nicola Temple and Catherine Whitlock manage to subvert that format - it is, indeed, presented as a series of separate two-page spreads, but there is far more…
