Relativity for the Questioning Mind – Daniel Styler ****

On first inspection my paperback copy of this book had the look of a self-published title, with the small text on the back cover going right to the edge of the page and the front cover looking a little amateurish. The book is, however, published by Johns Hopkins University Press – and, luckily, once you get inside, there are no problems with the layout and no doubts about the quality.
Relativity for the Questioning Mind is a little different from most popular science titles. It is ostensibly a workbook, with the idea being that the reader gets to grips with (mainly special) relativity through problem-solving rather than passive reading alone. Each short chapter sets a variety of problems to get you thinking, having first briefly introduced the relevant ideas and concepts, with hints and answers at the back of the book. Here is one of the simpler problems, in the chapter on time dilation, to give an idea of what these problems are like (the additional information and equations you need to solve the problems are always covered beforehand):
“I trim my moustache every six weeks. If I were in a rocket ship flying past you at [four-fifths the speed of light], then how much time, in your frame, would elapse between my moustache trimmings?”
The problems get trickier as the book goes on, and whilst they’re generally fun, many end up being quite a bit more difficult than you might expect, having been told at the beginning of the book that you will be gently introduced to relativity theory – although the author believes that the mathematics in the book is all elementary, some of it will still appear fairly forbidding to non-specialists. I do still like the approach, though – Styler is absolutely right in emphasizing that exercises like these can be of great use if you want to deepen your understanding of a subject area, and the author’s philosophy – work things through for yourself and don’t take anyone’s word for it – is a good one.
If you didn’t want to work through all of the exercises, there is still plenty to get from the book. The introductions to such things as time dilation, length contraction, the relativity of simultaneity, and the equivalence principle are useful in their own right, and there are interesting detours throughout the book on, among other things, the nature of science and its limitations.
There is one other aspect that I liked a lot – incorporated into the text are regular question and answer dialogues, in which Styler imagines confused readers interjecting with requests for clarifications or objections to what’s being discussed. Styler poses and answers the questions he believes most people have when coming across ideas in relativity theory for the first time, questions which he feels are not answered in most other places, and the conversational, and often humorous, tone of these sections makes them entertaining to read.
Overall, then – informative, challenging, and fun at the same time. Perhaps not the ideal introduction to relativity, but this would complement well books on the subject that take a more standard approach.

The God Game (SF) - Danny Tobey *****

Wow. I'm not sure I've ever read a book that was quite such an adrenaline rush - certainly it has been a long time since I've read a science fiction title which has kept me wanting to get back to it and read more so fiercely. 

In some ways, what we have here is a cyber-SF equivalent of Stephen King's It. A bunch of misfit American high school students face a remarkably powerful evil adversary - though in this case, at the beginning, their foe appears to be able to transform their worlds for the better.

Rather than a supernatural evil, the students take on a rogue AI computer game that thinks it is a god - and has the powers to back its belief. Playing the game is a mix of a virtual reality adventure like Pokemon Go and a real world treasure hunt. Players can get rewards for carrying out tasks - delivering a parcel, for example, which can be used to buy favours, abilities in the game and real objects. But once you are in the game, it doesn't want to let you go and is …

Peter Wothers - Four Way Interview

Dr Peter Wothers is a Teaching Fellow in the Department of Chemistry, University of Cambridge, and a Fellow and Director of Studies in Chemistry at St Catharine's College. He is heavily involved in promoting chemistry to young students and members of the public, and, in 2010, created the popular Cambridge Chemistry Challenge competition for students in the UK. Peter is known nationally and internationally for his demonstration lectures and presented the Royal Institution Christmas Lectures, titled The Modern Alchemist, in 2012. In 2014, he was awarded an M.B.E. for Services to Chemistry in the Queen's Birthday Honours.. His new book is Antimony, Gold and Jupiter's Wolf.

Why chemistry?

I’ve been pretty much obsessed with chemistry from about the age of 8.  I built up quite a substantial home laboratory with all sorts of things that are (quite rightly) banned now (such as white phosphorus) and also used to go to second-hand bookshops to find chemistry texts.  Eventually I boug…

Where are the chemistry popular science books?

by Brian Clegg
There has never been more emphasis on the importance of public engagement. We need both to encourage a deeper interest in science and to counter anti-scientific views that seem to go hand-in-hand with some types of politics. Getting the public interested in science both helps recruit new scientists of the future and spreads an understanding of why an area of scientific research deserves funding. Yet it is possible that chemistry lags behind the other sciences in outreach. As a science writer, and editor of this website, I believe that chemistry is under-represented in popular science. I'd like to establish if this is the case, if so why it is happening - and what can be done to change things. 

An easy straw poll is provided by the topic tags on the site. At the time of writing, there are 22 books under 'chemistry' as opposed to 97 maths, 126 biology and 182 physics. The distribution is inevitably influenced by editorial bias - but as the editor, I can confirm …
