Poster: Beach Spectres, we want to make the largest aperiodic tiling ever! What's an aperiodic tiling? It's when you cover a flat surface with copies of a shape like the one above, without any repeating patterns. The Spectre monotile was only discovered in 2023, and mathematicians are really excited about it! What are you doing? We're going to use large “cookie cutter” tools in the shape of the Spectre to cover the beach with the aperiodic tiling. You can help: come to the beach and we'll show you what to do. Where and when? Whitley Bay beach, 7th June 2026. Come and join in, just watch, or talk to some very enthusiastic mathematicians! beachspectres.com
I'm enormously happy to finally be able to announce the date of the #BeachSpectres project: 7th June, 2026. #WhitleyBay beach, UK.
If you can make it to the beach and join in with the tiling effort, I'll be very happy to see you and glad of the help!
Lots […]

Below is an excerpt from the late, great Vicky Neale’s book ‘Closing the Gap’.
Two sides of the pencil 😍 show numbers that are 2 mod 3. Prime numbers are shown in red.
Does anyone know where we can buy this pencil? 🙏

Those of you who teach the topic of circular motion in A level Further Maths Mechanics, do you use the term 'centripetal force'? It doesn't seem to be mentioned in the specifications I've looked at, though it is in A level Physics specifications. #ALevelMaths
