Why do mathematicians always want proof and what do they mean by it?

In this year's advent calendar we celebrate our collaboration with the Isaac Newton Institute for Mathematical Sciences.

We love talking to young researchers and laureates at the Heidelberg Laureate Forum, and this year we produced a daily video diary to take everyone behind the scenes of this special digital HLF.

Beware of exponentially small terms!

Explore the maths behind machine learning and deep neural networks with this collection of short introductions and in-depth articles.

Next month sees the 60th birthday of a famous algorithm called Quicksort. We explore its origin, its workings, and some other work of its inventor Tony Hoare.

Can physics shed new light on understanding language? Sanjaye Ramgoolam tells us about his exciting new approach that brings together theoretical physics, mathematics and computer science.

Explore the mathematical study of symmetry with this collection of content, which includes short introductions, in-depth articles, a podcast, and some magic!
