We can't visualise it, but we can still think about it! And there are clever ways of glimpsing what it might look like.

This article explores this most beautiful of numbers. Find out its definition, why its value can only ever be approximated, what it has to do with waves, and why it contains the history of the Universe. 

We celebrate pi day with a look at the number itself as well as some of its fellow numbers we particularly like.

This article describes how you can describe the entire universe of Riemann tori (surfaces that look like dooughnuts) in one go.

A Riemann torus is a surface that looks like a doughnut. This articles explored how you might tell Riemann tori apart.

How many different surfaces are there? The question seems impossible to answer, but mathematicians have a way of dealing with the multitude. Follow us on a journey into the world of moduli spaces.
