## topology

PhD student June Park talks to us about geometry and number theory.

In a previous article we found a Möbius strip in Bach's music. This time it's a doughnut shape.

Discover (and listen to) the Möbius strip that's hidden within one of Bach's famous canons.

This year's Nobel Prize for Physics brings together the physics of materials with one of our favourite areas of maths – *topology*. In this final article in a series, we asked Fiona Burnell to explain the maths behind the work, and how it may help lead to quicker and smaller electronics, and even the elusive quantum computer.

Find out how some black holes are bigger on the inside than they are on the outside.

How "forced experimentation" can lead to economic benefits.

A Klein bottle can't hold any liquid because it doesn't have an inside. How do you construct this strange thing and why would you want to?
