Symmetry may be very familiar and intuitive to us, but how can we talk about symmetry mathematically? We know that triangles and spheres both possess kinds of symmetry, but how are they related? The mathematics of symmetry can be described by "Group Theory".

# Symmetry at the Heart of Physics

It takes a fair few years of a university degree to begin to realise that symmetry is perhaps the most fundamental concept in modern physics. It's no accident that one of the leading candidates for new physics is called "Supersymmetry".
