The workshop will take place on Monday, **January 23, 2023, at 16:00** at the Technical University of Munich on the Garching research campus. The venue is Hösaal 3 in the Mathematics-Informatics Building, Boltzmannstraße 3. Bernd Sturmfels, Director at the Max Planck Institute for Mathematics in the Sciences in Leipzig, and Johannes Henn, Director at the Max Planck Institute for Physics in Munich, are organizing the workshop in collaboration with the SFB/Transregio 109, Discretization in Geometry and Dynamics.

Registration is not necessary if you wish to attend. The event is aimed at scientists with a bachelor's degree and higher from all relevant disciplines.

## Abstract

There are strong indications from physics at both infinitesimal and cosmic distances that our current understanding of the laws of nature is only approximate, and must be replaced by deeper principles. Novel geometric objects, in the setting of amplituhedra and Feynman integrals, hint at new mathematical structures. Combinatorics and algebraic geometry have been connected to particle physics and cosmology in an entirely unexpected way. This seminar is an invitation to join the discussion.
