A brief introduction to the strange theory of quantum mechanics and how it appears to afford a special role to observers.

So easy to describe, yet so hard to prove.

Mathematicians are working hard to understand an impenetrable proof of the famous ABC conjecture.

The possibility that there might be many parallel worlds has just become a little more likely.

This problem about an infinite sum has a surprising answer.

This surprising result about 3D shapes tells us something deep about the nature of space.

Euler may not have cracked this problem completely, but it led to a lot of important work, including on what we today know as sudoku.

Can you move a knight on a chessboard so that it visits every square exactly once? Euler was one of the first to analyse this problem systematically, but some questions about it are still open today.

James Maynard, one of the prize winners at the European Congress of Mathematics 2016, is counting primes that don't have 7s in them. But why?

Mathematicians explore how opinions spread through a society.

Sara Zahedi has won a prestigious prize at the European Congress of Maths. Your future medical diagnoses, and even the welfare of sea life, may depend on her work.
