## dynamical system

The division of plant cells is governed by their shape – just one example of how maths may reveal the fundamental laws underlying biology.

If you thought that billiards was a harmless game to play in the pub, think again. It's a breeding ground for chaos!

Here's an easy game that leads you straight to an unsolved question in maths.

Why doing maths is like being Lewis Carroll's Red Queen and how to keep going beyond the formidable age of 84.

Artur Avila tells us about taming chaos.

Artur Avila is being honoured for "formidable technical power, the ingenuity and tenacity of a master problem-solver, and an unerring sense for deep and

significant questions."

It's one of the most beautiful sights in nature: fireflies illuminating the night with their synchronised flashing. Mathematicians have just solved a 40 year-old problem behind this striking phenomenon.

The paths of billiard balls on a table can be long and complicated. To understand them mathematicians use a beautiful trick, turning tables into surfaces.
