On the 21st of October I gave a talk on "The theory of Grossone and the Continuum Problem" (joint work with Y. Sergeyev) at the 14th French PhilMath (https://fpmw14.sciencesconf.org). It was an exciting opportunity to present to a specialised audience the (little known) theory of grossone, its foundational and practical implications, its consequences on our conception of the infinite.
