Beyond the Hoax – Alan Sokal ****

I ought to say straight away that this is only a borderline popular science book as the heavy use of footnotes and massive bibliography for each chapter suggests. It’s half way between a collection of light scientific papers and a book for the general reader. The other proviso up front is about those four stars. In practice this is an average score. It really is five star for some of the content, but three star for presentation and other parts of the content.
The ‘hoax’ in question is a famous one in physics and an infamous one in the soft sciences. In 1995, physicist Alan Sokal had a paper published in the well-established journal Social Text called ‘Transgressing the boundaries: Towards a transformative hermeneutics of quantum gravity.’ It was a parody. The idea was to demonstrate how writers in the humanities and social sciences were taking concepts from physics and using tons of woffle to totally distort the science and to pretend they in some way they demonstrated that there were no objective truths of nature, but merely subjective interpretations, based on the culture of the scientists.
This kind of approach is easy enough to mock (‘If you don’t believe in the objectivity of physics, please do walk out of my 22nd floor office window and try to be subjective about gravity!’), but the genius of Sokal’s parody is that he demonstrated that calculated rubbish would be accepted by this community because they hadn’t the faintest idea what they are talking about. As Sokal points out later in this book, this isn’t just a case of putting down a few ivory tower academics spouting nonsense (thought that is quite appealing). It’s also about defending science when it’s under attack using cultural arguments, whether nationalistic, gender-based or on religious grounds.
The book starts with Sokal’s original paper, in an annotated form so you can appreciate the full genius of the parody. This is quite hard to read – the annotation sometimes runs longer than the original, and as there are also quite a lot of footnotes in the original you often end up reading an annotation to a footnote to a comment. But it’s worth struggling through to understand where it all comes from.
We then get a series of chapters that were mostly articles on different aspects of the hoax and what it brought out, whether it was the immediate reaction of those attacked by the hoax or the dangers underlying this idiocy. There is a lot of powerful material here, not only in getting a picture of how detached from reality some academics have become, but also in understanding just what science is, what it does and what it’s for. Because of this I would highly recommend this book is read by anyone writing about science, the history of science or the philosophy of science. The insights are very useful, from a picture of how to treat the likes of Popper and Kuhn to a feel for the fundamental nature of the scientific method. In this sense, it is genuinely one of the most important books on science I have read.
But I do need to balance this view with the negatives. It is decidedly hard to read – certainly not conventional popular science. In part this is because you have to plough through quite a lot of the garbage pumped out by some of these arty academics, which bears a startling resemblance to the pseudoscience used by quacks to support their ‘holistic energy therapy’ or whatever. Interestingly, Sokal makes the comparison, but is a little disappointed to find that the postmodernist academics don’t support pseudoscience as much as he expected. But it is also hard to read because of the way the book is structured.
At the start, Sokal says ‘I have a visceral distaste for books that have been confected by pasting together a collection of loosely connected, previously published essays.’ He argues this book isn’t such a tome. But it is, it really is. The contents have only been very loosely edited – there is a lot of word-for-word repetition between chapters and the whole doesn’t flow particularly well. Making matters worse, all the chapters are heavy with footnotes. I don’t mind the references, but a lot is text that in a proper book would be part of the main flow of the text, so you have to keep flipping about while reading it. Very frustrating, and frankly lazy to leave it like this.
The other evidence in favour of the ‘loose pasting together’ argument is that the book ends with a couple of chapters that are hardly connected to the rest at all, but rather a sub-Dawkinsesque attack on religion. These chapters lack the intellectual rigour of the rest, being full of attempts to apply science to areas where science really doesn’t work very well. Some of the statements here are self-contradictory and the chapters feel like a chance for Sokal to let off some steam, rather than apply scientific thought appropriately.
Definitely a curate’s egg, but the tasty parts are very tasty indeed.

Cosmology for the Curious - Delia Perlov and Alex Vilenkin ***

In the recently published The Little Book of Black Holes we saw what I thought was pretty much impossible - a good, next level, general audience science title, spanning the gap between a typical popular science book and an introductory textbook, but very much in the style of popular science. Cosmology for the Curious does something similar, but coming from the other direction. This is an introductory textbook, intended for first year physics students, with familiar textbook features like questions to answer at the end of each chapter. Yet by incorporating some history and context, plus taking a more relaxed style in the writing, it's certainly more approachable than a typical textbook.

The first main section, The Big Bang and the Observable Universe not only covers basic big bang cosmology but fills in the basics of special and general relativity, Hubble's law, dark matter, dark energy and more. We then move onto the more speculative (this is cosmology, after all) aspects, brin…

Astrophysics for People in a Hurry – Neil deGrasse Tyson *****

When I reviewed James Binney’s Astrophysics: A Very Short Introduction earlier this year, I observed that the very word ‘astrophysics’ in a book’s title is liable to deter many readers from buying it. As a former astrophysicist myself, I’ve never really understood why it’s considered such a scary word, but that’s the way it is. So I was pleasantly surprised to learn, from Wikipedia, that this new book by Neil deGrasse Tyson ‘topped The New York Times non-fiction bestseller list for four weeks in the middle of 2017’.

Like James Binney, Tyson is a professional astrophysicist with a string of research papers to his name – but he’s also one of America’s top science popularisers, and that’s the hat he’s wearing in this book. While Binney addresses an already-physics-literate audience, Tyson sets his sights on a much wider readership. It’s actually very brave – and honest – of him to give physics such prominent billing; the book could easily have been given a more reader-friendly title such …

Once upon and Algorithm - Martin Erwig ***

I've been itching to start reading this book for some time, as the premise was so intriguing - to inform the reader about computer science and algorithms using stories as analogies to understand the process.

This is exactly what Martin Erwig does, starting (as the cover suggests) with Hansel and Gretel, and then bringing in Sherlock Holmes (and particularly The Hound of the Baskervilles), Indiana Jones, the song 'Over the Rainbow' (more on that in a moment), Groundhog Day, Back to the Future and Harry Potter.

The idea is to show how some aspect of the story - in the case of Hansel and Gretel, laying a trail of stones/breadcrumbs, then attempting to follow them home - can be seen as a kind of algorithm or computation and gradually adding in computing standards, such as searching, queues and lists, loops, recursion and more.

This really would have been a brilliant book if Erwig had got himself a co-author who knew how to write for the public, but sadly the style is mostly heavy…
