Fascinating colloquium about the 200 Swiss frank banknote
The new 200 Swiss franc banknote displays the history of our universe from the big-bang over the formation of particles and atoms to our planet. Its backside is showing an event following a collision in a high-energy particle physics collider. The designers of the new Swiss banknote series, Manuela Pfrunder and Adrian Heuberger, together with the scientific advisor Günther Dissertori from ETHZ gave a fascinating PSI-colloquium on the topic on Nov 15, 2019.
