Smiling while reading about group theory and Rubik’s cube

For the average chemist, mathematics is usually a tool rather than a subject of study in its own right. Yet it is precisely mathematics that allows many complex chemical problems to be solved. After all, who has never been rescued by a Laplace or Fourier transformation? In Schitterende Symmetrieën (Brilliant Symmetries), Roel Andringa-Boxum explains how symmetry underlies fundamental physics and how it helps describe the most elementary as well as the most macroscopic phenomena. The theories and formulae are explained step by step, related to relevant scientific applications. The chemist may be disappointed to find that this book does not place particular emphasis on symmetry in chemistry. Chirality, for instance, receives only a brief mention.

But then Andringa-Boxum is a physics teacher, not a chemistry teacher, and it is plain to see that he has found his calling. I envy his pupils. If he teaches in the same manner in which he has written this little book, it can only be a matter of time before a great number of the young people in his classroom enthusiastically sign up for a science degree.

Ironic footnotes

The amusing and humorous way in which he unravels the secrets of group theory ensures that you grasp even the more challenging material with greater ease. According to the publisher, a knowledge of algebra at secondary school level is sufficient to understand the book. It has been quite a few years now since I studied mathematics at school. And although I still take great pleasure in working through problems, I did find myself having to re-read certain passages here and there in order to fully grasp the theory.

‘This reviewer, writing from Italy, was particularly gratified that Andringa-Boxum sees fit to ban pineapple on pizza’

The book never becomes dull for a moment. The author manages to make even the most abstract mathematics tangible through everyday examples. A particular mathematical operation, for instance, is described by way of putting on and taking off shoes and socks. And thanks to the generous sprinkling of ironic footnotes, I frequently found myself reading on with a broad smile. This reviewer, writing from Italy, was particularly gratified that Andringa-Boxum sees fit to ban pineapple on pizza. Another appealing draw is ‘the secret behind the Rubik’s Cube’. Having read this book, you ought to be able to solve one — without an app or a screwdriver. That remains quite a challenge, I can assure you.

Enthusiastic teacher

How wonderful it would be to read this book alongside Andringa-Boxum’s own lessons on the subject. And how clearly it illustrates, once again, the importance of enthusiastic teachers in conveying knowledge. The ‘Nerd from the North’, as he describes himself on his website, has made it his mission to show people the beauty and importance of science. I would advocate for more books of this kind — though perhaps even more accessible, so that those with a fear of the sciences might also be inspired.
