These talks will be self-contained presentations of mathematical concepts and theorems. They are intended to be accessible to all mathematics
students.  Coffee, tea and drinks will be provided.

The beauty of soapfilm and soapbubble surfaces holds a fascination for mathematicians and non-mathematicians alike. In this talk, we will highlight some of the geometric features of these surfaces. In particular, we will explain why even complicated soapbubble clusters exhibit very simple structures. Connections to shortest network problems will be outlined.
