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.
Our neighbour Oscar Randal-Williams tells us about his exciting work at the frontiers of mathematics and the fundamental question he might be just about to answer!
What is group theory and why is it such an exciting area of maths? Two experts explain.
2018 is the centenary of a mathematical result that changed the character of physics.
Symmetry is one of the two guiding principles in understanding probabilities – if different outcomes are equivalent they should have the same probability.
We all instinctively recognise symmetry when we see it, but describing it in words is harder than you might think.
We all know what symmetry is. But why does it play such a central role in modern physics?
