How about Roger Penrose and his obsessional walks? Or a mathematical joke about an errant dog? Or more from agony uncle Josh Bull as he tells us how to best stir your tea?
All three and more feature in our latest short films which you can watch on YouTube. They are also all available on our social media channels (you can find the social media links at the bottom of this page).
Roger's film is below and this link takes you to them all if you have time including Mie Gluckstad (image) on the pros and cons of random walks.
