Public Lecture “Kanonen auf Spatzen: Eine große Reise durch die Mathematik für ein kleines Problem aus der Geometrie”
Sometimes simple questions require intricate mathematical solutions: We are excited to announce the public lecture by Prof. Dr. Günter M. Ziegler (Freie Universität Berlin), "Kanonen auf Spatzen: Eine große Reise durch die Mathematik für ein kleines Problem aus der Geometrie".
For his talk, Prof. Dr. Günter M. Ziegler will take his audience on a journey through mathematics to answer a seemingly simple geometry question, posed by R. Nandakumar on a blog post in September 2006: "Can every polygon be partitioned into a prescribed number of convex pieces, each with the same area and the same perimeter?"
The talk will take place on Friday July 10, 2026 at 5 pm in the new audiMAX lecture hall (INF 289), and is targeted especially to high school students and mathematics enthusiasts. The lecture will be in German.
All interested are welcome to attend, as the talk is free of charge, with no registration required. For further information, please visit the event’s website.
This event is organized by the Research Station Geometry + Dynamics, a research centre within the Institute for Mathematics (IMa) at Heidelberg University. The station brings together researchers working at the interface of geometry, topology, group theory, and dynamical systems. Alongside its research activities, it is committed to education and public engagement through outreach initiatives that make mathematics accessible to a wider audience.
