Tangled Christmas Lights and Other Knotted Problems - Dr Graham Reeve
29th November 2025
Do you know the difference between a reef knot and a granny knot? And how can you tell a taut-line hitch from a sheet bend? In this session, we'll explore how you can use ordinary high-school algebra to learn about knots. Which then has all sorts of real-life applications from sailing and putting up a tent, to detangling strands of DNA or indeed those pesky Christmas lights. (Don't worry, no knowledge of actually tying knots is assumed!).
