Extra Sensory – Brian Clegg ****

As a subject, extra sensory perception, ESP, psi or whatever you want to call it hovers on the frivolous edges of science. And yet there certainly is something for science to investigate, whether it is an actual physical phenomena or the oddities of the human mind that make it susceptible to believing in such possibilities. 

The editor of this site, Brian Clegg, has decided to take the scalpel of science to areas of the paranormal where an attempt has been made to make a controlled and scientific assessment, limiting himself to those areas that could have a scientific explanation, as opposed to those that rely on the supernatural. So we are talking about the likes of telepathy, telekinesis, clairvoyance and remote viewing.

I had always got the impression that the first to take a really scientific approach was Rhine in the 1930s – in reality it seems that athough these early investigators employed the trappings of science, a lot of the tools they used, particularly the controls and the maths, were applied rather carelessly. What’s more this lack of precision seems a common theme in much of the subsequent scientific exploration of mental powers.

All the way through, Clegg makes the book very approachable, using an introductory story to get into each chapter, looking at possible scientific explanations and exploring the attempts of academia to get to grips with everything from Uri Geller to bizarre experiments straight out of a David Cronenberg movie with half-ping pong balls taped over the subjects’ eyes. He opens up all the means of deception, whether accidental from misunderstanding statistics to explaining the tricks used by magicians and mentalists to give the appearance of having psi abilities.

Almost inevitably, there isn’t a huge amount of science in it – which is hardly Clegg’s fault, it is just the nature of the subject. Inevitably his attempts to provide possible scientific explanations for the likes of telepathy are a little speculative, but overall this is a refreshing attempt that unusually for this subject treads the tightrope of proper scientific enquiry. It is neither the total denial of the ultra-skeptic who will not even consider any evidence (Clegg quotes Richard Dawkins literally saying ‘I am not interested in evidence’) and the feeble acceptance of any old rubbish made by those who never question whatever they are told by psychics. Good stuff.

Review by Peter Spitz
Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

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...

The Random Universe - Andrew Jaffe *****

This is an absolutely fascinating book for anyone interested in the way that science really works, bearing in mind the difficulties of having to base our models and theories on induction. Andrew Jaffe introduces the difficulties we face when trying to take a scientific view because largely we are dependent on induction: predicting the future from what has previously been observed. He explores what probability is, the two key ways of looking at it (frequentist and Bayesian) and how scientists use (or misuse it) to work out the implications of their experiments for hypotheses. This is then expanded into looking at the nature of scientific models and the philosophy of science before heading out to entropy, quantum randomness and attempting to achieve meaningful cosmology with its potential dearth of evidence.  The topic might sound a little dry, but in fact Jaffe does it with good humour and a very readable style. For example, he uses measuring his daughter's height by making marks on...
