The Blind Spot - Adam Frank, Marcelo Gleiser and Evan Thompson ****

This is a curate's egg - sections are gripping, others rather dull. Overall the writing could be better... but the central message is fascinating and the book gets four stars despite everything because of this.

That central message is that, as the subtitle says, science can't ignore human experience. This is not a cry for 'my truth'. The concept comes from scientists and philosophers of science. Instead it refers to the way that it is very easy to make a handful of mistakes about what we are doing with science, as a result of which most people (including many scientists) totally misunderstand the process and the implications.

At the heart of this is confusing mathematical models with reality. It's all too easy when a mathematical model matches observation well to think of that model and its related concepts as factual. What the authors describe as 'the blind spot' is a combination of a number of such errors. These include what the authors call 'the bifurcation of nature' - splitting between what is based on theory and considered objective and what we actually experience which is seen as second class and subjective. An example they give is the idea espoused by many scientists that colour (as opposed to wavelength of light) is an illusion.

Perhaps the most familiar of the errors is reductionism - considering that if we can break a system down to its most basic elements we can fully understand it from the behaviour of those elements. This entirely misses emergence, complex systems and chaos, not to mention practically any social science. Then there is physicalism (what used to be called materialism, but, as is pointed out the concept of fields in physics, for example, is not material), the reification of mathematical entities and the notion that experience is epiphenomenal. Those last two are where we consider the properties of the universe that can be subjected to mathematics as the only real ones, and where we consider conscious experience to be an unreal construct of computation in the brain and hence worthless scientifically.

This kind of problem in science is related to that uncovered by Sabine Hossenfelder in the (much better written) Lost in Math, but that book is purely about the way that modern physics often builds whole theoretical structures on mathematical models without any great connection to observation and experiment, where more emphasis is given to the 'beauty' of the maths than its relation to reality. And there's also a touch of Kant's concept of the 'Ding an sich' - the unknowable reality of the universe where we can only discover the phenomena it produces. But what's new here is that the blind spot extends to vast swathes of science, where we put far too much emphasis on idealised models that bear only a passing resemblance to reality and take far too little notice of what we actually experience and observe.

To dig a little into my complaint about the writing, by far the best bits were those dealing with time, matter, the cosmos and AI, while the sections on life, Earth science and climate change were particuarly weak. Consciousness was also covered - the content was interesting, but that section was somewhat laboured. I also think the structure of the book could have been better. In essence, it introduces the blind spot and its characteristics (which are all labelled with incomprehensible terminology once we get past the approachable 'blind spot'), then has sections on each of the topics. The trouble with this was that it was quite difficult to keep in mind what something like 'reification of mathematical entities' meant as we went from discipline to discipline. It might have been better to structure the book by the elements of the blind spot and bring in different disciplines to illustrate them instead. There was also rather too much unnecessary history of science, some of which was on slightly dodgy ground, for instance appearing to equate phlogiston (effectively un-oxygen) with caloric (an imagined fluid corresponding to heat).

As mentioned at the beginning, despite some issues, the concept is genuinely important. The authors are not advocating for some fluffy person-centred pseudoscience, but rather for more realism in science that takes in what is happening, rather than just simplified mathematical models and that recognises that experience is an important part of how we should look scientifically at the world.

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...
