The Fly Trap - Fredrik Sjöberg *****

I have to beg the popular science reader's indulgence a little with this title as there's not a huge amount of science in it - but it is the most delightful book I've read so far this year. What science there is sits very firmly in Rutherford's category of 'stamp collecting', but there are still interesting insights into the drive behind natural history and the urge to catalogue. 

Fredrik Sjöberg refers to the 'stamp collecting' aspect as buttonology, a term he takes from Strindberg, one of many literary references. Generally speaking, I hate popular science books where the author has the illusion that he is writing 'literature' and churns out a choppy mess of allusions and metaphor. But that's not at all what is happening here. Unlike those authors with pretensions of artiness, here there is nothing pretentious.

Let's get the science bit in first. Sjöberg is an entomologist; specifically he spends his days collecting and classifying hoverflies. I so wish he allowed himself to tell us a bit more about the creatures themselves. There are plenty of passing references to various Latin names and habitats and more - but like most people, I suspect, I had just thought of hoverflies as those rather poor small copies of wasps that hover about in a most un-wasplike manner. I hadn't realised there were species that imitated everything from bumblebees to hornets - and some were almost indistinguishable from the real thing without an expert eye. I genuinely wanted to read more on hoverflies and their lives.

What Sjöberg does do, though, is to give a kind of defence of the stamp collecting aspect of natural history (while gently poking fun at the collecting urge), showing how it goes beyond simple ticks of the box to the link between different species and habitat, or changes in the environment. However there is much more to the book than the science, as is made clear by the opening where we meet a youthful Sjöberg in a job as a props person in a theatre, left in charge of the live sheep required for a particular play.

In his many idle hours - because apart from simply thinking while waiting around for flies, Sjöberg seems to spend a fair amount of his time doing anything other than working - rather like an author in that respect - Sjöberg has the chance to consider literary parallels to his situation, and to fill in details on his other passion, the life and work of the Swedish entomologist René Malaise. Apparently Malaise is a byword in the business for defining the definitive large, tent-like fly trap, but Sjöberg takes up nearly half of the book on Malaise's adventures in Kamchatka, his theories on Atlantis, his life in general and his art collection. The artworks (and Sjöberg's attempt to buy one) finish the book, for me rather weakly as it's the least interesting part of the story.

Seen as a whole, the book has two main recurrent themes, collecting and islands, because Sjöberg does all his collecting, year after year, on one small Swedish island, where he has by now identified 202 hoverfly species. And for me, this is where is writing is best, evoking excellent wild country memoirs like Neil Ansell's Deer Island. But throughout the book Sjöberg maintains interest in a way it's hard to imagine the thoughts of a Swedish hoverfly collector doing. I was sad when I got to the end - fairly quickly, both because I wanted to keep reading and because the book is shorter than it looks, as the text is unusually widely spaced. In part, the accolade for keeping my interest has to go to the translator Thomas Teal, but it's Sjöberg's light but penetrating observations, gentle humour and butterfly mind (see what I did there?) that keep the reader enthralled.

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…
