It has long been known that information can spread in much the same way that diseases do. The same mathematical models are used to study how a new idea and a new virus infect a population. For more information come to the Wittgenstein Lecture from June 15 to 19 2026!

I'm late on this but I've just read that Krister Segerberg passed early February: www.uu.se/en/departmen... He's been an inspiration way back during my MA, and I'm still amazed at how kind, constructive (and in retrospect so patient!) he was when I had the privilege to meet him some years later.
