A lecture by Professor of Mathematics Sylvie Benzoni-Gavage.

Members’ priority until 5th July


Ulysse Lacoste’s Rulpidon is both a sober and fascinating shape that can roll surprisingly smoothly and has an intriguing number of “holes”. This can inspire various thoughts in a mathematician’s mind, including the crazy idea of designing colourful maps of it subject to certain constraints. The Rulpidon made me embark on an enthralling journey dotted with drawings and other manual work. Come along with no prior knowledge required and join me as we walk paths that may challenge your intuition. Meanwhile, you will get a glimpse of what it feels to be a mathematician confronted by a novel problem, as innocent looking as it might be, and how creativity and perseverance come into play.
