What exactly do we mean when we say group theory is the study of symmetry? Group actions make precise what it means for a group to act by symmetries on an object.

Find out how a story starting with the simple notion of counting ends in a revolutionary new way of doing maths that uses computers to harness the power of human collaboration!

We celebrate the run-up to the European Congress of Mathematics (ECM) with Fields Medallist Maryna Viazovska who previously won a prestigious EMS prize at the ECM.

Why do penalty takers not heed the advice of statisticians? We find out with a little game theory.

Make your sweepstake for the Euros fairer and more exciting!

How many ways can you write a number as the sum of smaller numbers?  

In the run up to the European Congress of Mathematics we continue our series of interviews with mathematicians who've won the prestigious Fields Medal. This week we hear from Artur Avila talking about his work on taming chaos.

The age of Big Data poses a risk to our privacy as even anonymised data can sometimes be linked to individuals. Differential privacy provides a way of protecting sensitive information even when some of it is made public.

Artificial intelligence algorithms are often trained on people's personal data. How can we make sure that this data remains private? 

How does artificial intelligence manage to produce reliable outputs? Stochastic gradient descent has the answer!

The advent of artificial intelligence poses new threats to the privacy of our personal data.  We explore the challenges and a way to address them.

In the run up to the European Congress of Mathematics we continue our series of interviews with mathematicians who've won the prestigious Fields Medal. This week we hear from Alessio Figalli talking about the theory of optimal transport.
