My guest is Katie Steckles, Mathematician, presenter and communicator. She has written seven books about mathematics, hosts the brilliant Mathemetical Objects podcast where she and her co presenter Peter Rowlatt discuss with their guests, very ordinary objects, and sometimes weird ones, and the mathematics behind and because of that object.

The kind of podcast I would love to have made if i were cleverer and had thought of it. It's a very interesting chat about the arbelos, kalaidocycles, bringing the stories of mathematics to light, the skill of not knowing what you are doing, Euclid's brother, Pythagoras's very existence, Jeff Goldblum, and a global maths communications hub built on a submarine in Katie's long term plans.

Again apologies for the aperiodical nature of these podcasts - pretend it's another era and post gets held up in winter storms. ANyway it's fitting as Katie's website is call Aperiodical.com and describes that lack of pattern in her blogposts.

Things you can look up afterwards - the kaleidocycle, the tetrahedron, Andrew Wyles - the man who solved Fermat's last theorem. Tim Gowers, an expert in combinatorics, Terence Tao, childhood genius who kept getting better, and the late Maryam Mirzakhani. Jurassic Park dragon curve and chaos theory. It's all to do with fractals. And I'm going to do lots more on that.
