The Future of Seeing - Daniel Sodickson ****

At first glance a book about imaging technology sounds like one of those promotional titles that technology companies make about themselves that no one will ever read - but with a light, approachable touch, Daniel Sodickson takes us from the imaging mechanisms of nature, through the early technology to the present and the potential future - featuring both benefits and risks - with aplomb.

It wouldn't have struck me to include eyes in a history of imaging, but Sodickson successfully does so, going back even further to the first biological cells developing. As he asks in his opening '"OK, wait just a second!" I hear you cry. "What does imaging have to do with the first cells?"' - this chatty approach pulls the reader in very effectively. (You'll have to read the book to get the answer.) We then get on to the first augmentation of nature, using lenses to modify the flow of light. 

As always there's the potential for a non-historian to distort history of science, but on the whole Sodickson avoids the familiar traps, though I slightly question the idea of Robert Hooke being called 'England's Leonardo' by anyone serious, and was a bit disappointed with the way a chapter that finishes with introducing photography and moving pictures with Niépce and Daguerre without mentioning Fox Talbot or Muybridge.

The advantage of seeing things differently from the imager's viewpoint is we can then move on straight to X-rays and computerised tomography (in a chapter bluntly labelled 'slicing without cutting'). At this point, Sodickson takes a step back into the nature of an image - and what they are in the modern sense. He pulls together the current position with a dip into the democratisation of imaging due to ubiquitous technology and the impact of AI before plunging into future possibilities - from the use of non-optical imaging, to how AI will go much further not just in creating images but in understanding image content, covering positives, for instance in medical use, but also negatives in terms of privacy. There's no doubt that imaging's impact on the everyday will continue to develop and expand. As Sodickson says in his epilogue 'The story of imaging, meanwhile, is not just a story of experts and their tools. It is a broader human story.'

My only real complaint about the book is the chapter 'The community of imagers' which has photos (not surprisingly) of a page-full of people working in the field with a series of (metaphorical) snapshots of who they are and what they cover. It's common for scientists writing popular science to overdo acknowledgements of other scientists, and there's always a danger of it becoming a slightly tedious list of accomplishments. There are a few interesting points in here, but I'm not sure it improves the book.

Overall, an interesting take on a topic that is rarely thought of by the rest of us as a field in its own right, and hence is refreshing to experience in Sodickson's capable hands.

Beyond Belief - Helen Pearson *****

Apparently it comes as a surprise to many that medicine was not particularly scientific until the end of the twentieth century (to be honest, it's no surprise to me - we had a GP who used homeopathy in the 90s). Instead it was based on anecdotal guidance - the kind of thing that appeared to work. Evidence-based medicine has since improved the field, trying where possible to base decisions on evidence, ideally based on randomised controlled trials. The first part of Helen Pearson's book covers this well - though I think it's by far the least interesting part of what we discover. Instead what's truly fascinating is the rest of it, looking at a wide range of other fields where evidence was rarely properly used and that are only now starting to dip a toe in the water. These include social policy, policing, conservation, business and education. The main part of the book gives us examples of how bad these areas have been in terms of basing decisions on what's always been ...

The Infinite Book – John D. Barrow ****

Authors are often asked to review books on a topic they’ve written on themselves. The reasoning is sensible – they ought to know something about the subject – but there’s always that uneasy suspicion that there’s going to be a bit of bias creeping in. So I think it’s only fair to admit up front that I have written a book on infinity (of which more later). Infinity is a wonderful subject, because it’s intimately mind-bending (if the combination sounds paradoxical, that’s what infinity is all about) and gives you the chance to pull in all sorts of different concepts and assocations along the way, something Barrow does with great gusto. There’s a surprisingly large amount of coverage here for God, and for the universe, and the book jumps around from Aristotle to Hilbert’s Infinite Hotel (explained at great length), from the paradoxes of infinite sets to the paradoxes of time travel. Overall it’s an enjoyable journey that gives plenty of opportunity to be amazed and surprised. The...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...
