The Code Book – Simon Singh ****

Not in quite the same class as Singh’s definitive Fermat’s Last Theorem, but still a fascinating survey of the history of code making from the earliest days, through thewartime Enigma machines to the present day complexity of 128 bit encryption.
The great thing about the book is probably not the mathematical complexity of modern codes and ciphers but the very human studies of the use and need to transmit secret messages, from the ancient Greeks writing on a messengers bald head, then waiting for the hair to regrow, through the cipher that doomed Mary Queen of Scots to the race to crack the World War II Enigma machines.
One of Simon Singh’s great strengths is being able to get across complex principles in a way that the everyday reader doesn’t find intimidating. This shines through in The Code Book I don’t know if recent editions have the rather cringe-making ‘cipher challenge’ in the back – we can but hope this has disappeared by now – but this shouldn’t put anyone off.
Whatever your mathematical level or inclination, this book is likely to have something to offer.

Why? - Philip Goff *****

It might seem a bit odd to review a popular philosophy book here, but Philip Goff's content overlaps sufficiently with cosmology that it's appropriate, and that content is fascinating, even though chances are you won't agree with Goff all the way. The point of this book is to suggest that there is purpose behind the cosmos. The main evidence for this that Goff uses is the fine tuning of our universe that makes it suitable for life. Most cosmologists agree that this is odd, but many try to explain it using the idea of the multiverse. With some nifty mathematic-less probability (though he does invoke and describe Bayes theorem), Goff demonstrates convincingly that this argument does not hold up. (You can see some detail of how he shows that it's rubbish here .)  We then take a look at a couple of alternative explanations - a deity, or the universe itself embodying a degree of purpose, which comes under the banner of panpsychism. I didn't honestly find the arguments in

Short Cut: Maths - Katie Steckles (Ed.) ****

As a reader, I'm generally something of a sceptic on the subject of highly illustrated books that cover a topic in a series of two page spreads, but I surprised myself by enjoying Short Cut: Maths . It's described online as a paperback, but it's actually a quite handsome hardback. The book is divided into eight sections (numbers, structures, logic, geometry and shape, functions, probability and statistics, modelling and games) each of which contains six or seven spreads in the form of answers to questions. These range from the straightforward 'How high can you count on your fingers?' or 'Why can't you un-square a number?' to the intriguing 'Can a baby manage a crocodile?' and 'How many hairs are there on a bear?' As is often the case with this style of book, there are several contributors whose names are quite hard to find - as well as consulting editor Katie Steckles, we have Sam Hartburn, Alison Kiddle, and Peter Rowlett (plus illustrat

Consciousness - John Parrington ****

Consciousness provides what is the arguably biggest gap we have in our scientific knowledge. Unlike quantum physics or the detail of cell biology, this is a subject we all experience directly in our everyday lives. We know that we appear to be conscious. But what consciousness really means, if it exist at all and how it can be studied scientifically are all issues that science bumps up against repeatedly. John Parrington starts us of with some basic background to the history of consciousness 'science' from Artistotle, through Descartes to the modern distinction between the understanding of mechanisms for how we sense, remember, react to stimulus and so forth and the 'hard problem' of explaining the subjective sense of being us and our feelings. Parrington argues that our human-style consciousness, which he suggests is different from that of other animals, is a consequence of our use of language and our ability to use tools to radically transform our environment, combin
