"Some bits of mathematics are completely free of equations: just about patterns. I want to tell you about such a bit of maths, with no equations at all."
Watch this talk by Professor Imre Leader (Department of Pure Mathematics and Mathematical Statistics, University of Cambridge) to discover the area of mathematics called Ramsey Theory, and explore visual proofs.
This talk was originally given to an audience of 16-17 year olds.
This is accessible at school level. We should have such talks with our senior math students on a regular basis
