Prior to the main lecture by Martin Hairer, recipient of the Fields Medal in 2014 and based at the EPF Lausanne, there will be a talk by IMAGINARY (Andreas Matt) on “interactive mathematics”. During this talk, attendees of the Gauß Lecture are encouraged to bring their tablets, laptops, or mobile phones. The presentation will be designed to actively engage the audience, featuring a wide array of interactive programs from IMAGINARY. This means attendees can experiment and play along with the content presented right from their own devices.
