A travel guide to symmetry | A singular mathematician on tour in Europe

By Anna Behrend

Bright green, shocking pink or loud checks – you can’t easily miss Marcus du Sautoy. Nothing much else about him fits the image of a professor of mathematics either. When he talks about maths he doesn’t quote formulae but, with a cheeky grin, tells amusing anecdotes. What he does have in common with other mathematicians is his passion for his subject – particularly symmetry.

Born in the UK, Marcus du Sautoy’s research focuses on the symmetry of mathematical objects, which can have many thousands of dimensions. But even in his everyday life, or indeed on holiday, the search for symmetry is omnipresent. And what he has discovered so far, he has put together in his book Finding Moonshine

In many ways the book is a travel guide: on the one side, the reader is a time-traveller, journeying through the history of mathematics.  Marcus du Sautoy talks about the ancient Greeks searching for the basic building blocks of symmetry and about modern mathematicians whose research is so specialised that only a handful of people can understand it. Along the way, he continually gives the reader a sense of the beauty of complex mathematical structures and the obsession of mathematicians. On the other, du Sautoy describes his journeys in Europe. Together with his family he investigates places where artists and architects have been inspired by symmetry.

Carved stone balls

Museum of Scotland, Edinburgh, Scotland

Symmetry inspired artists right back in the Stone Age: around 2500 B.C. carvers toyed with the symmetrical properties of stone balls.

Early Stone Age dice

The symmetry of these tetrahedral dice determines the probability with which a certain number occurs.

Alhambra

Alhambra, Granada, Spain

This Moorish fortress is also known as the Palace of Symmetry. Here, you really can find all 17 two-dimensional symmetries in the artistic ornamentation.
