Number Freak – Derrick Niederman ***

Things didn’t start well with me with this self-confessed ‘mathematical compendium from 1 to 200′. On the front it has a quote from Carol Vorderman. ‘This book is a complete joy. It made me smile. A lot.’ Is it really a recommendation that a book made Carol Vorderman smile? This started me off in a nervous disposition.
When it comes down to it, this is one of those books that takes a theme and batters it to death. ‘I’ll list every number between 1 and 200 and write something interesting about it,’ thought the author. (Except he couldn’t find anything at all to say about 183.) Oh, good – a bit like counting sheep. Inevitably this format leads to a forced style, but to be fair, Derrick Niederman does manage to dig up some quite interesting material (occasionally it feels like wading through one of the worse episodes of QI) about the numbers in question. At these points it can be entertaining. But all too often I found myself thinking ‘not another…[insert mathematical structure of your choice].’ It all gets a bit samey.
This is not helped by a rather limited ability on the part of the author to explain mathematical matters lucidly. Several times I found myself having to read a paragraph two or three times to try to understand what Niederman was trying to get across. Even straightforward English sometimes presents a challenge. Take this comment about the Olympic rings. ‘Although the colours of the rings – blue, black, yellow, green, and red – do not correspond to [the five regions of the world] in a one-to-one sense, each of these five colours is represented in every national flag in the world.’ Really? Where is the yellow and black in the Union Flag or the Star Spangled Banner? It just doesn’t make sense. What he probably meant is that every national flag contains at least one of these colours, but it’s not what he said, and someone writing about maths should understand the need for precision.
I’d also have been a lot happier if the book gave some explanations for some of the apparently arbitrary labels of mathematics. For instance, we are told 6 is the first perfect number (it’s the sum of the numbers that divide into it, 1, 2 and 3). I knew that. But what I didn’t know, and would like to know, is so what? What does this signify? What does it do or provide us with as a piece of information? How can we use it? It’s just left dangling.
All in all, highly curate’s-egg-like as a reading experience. It’s very rare I don’t get all the way through a book, but I confess I couldn’t be bothered to finish this one.

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…

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…
