Mathematik ist in Musik - Mathematics is in Music

UNESCO has declared the 14th of March to be the International Day of Mathematics (IDM). The topic in 2020 is “Mathematics Is Everywhere”. #idm314. The International Mathematical Union is putting together a collective video for this event. Clips from all over the world will illustrate the various places where math can be found. The final video, made up from the best submissions received, will be presented at the IDM launch event at the UNESCO headquarters in Paris, at the African launch in the Next Einstein Forum 2020 and shared online. The video here is our contribution to this video competition. It was produced by uni-bonn.tv (https://www.youtube.com/user/UniBonnTV). Many thanks to the director of photography, Gunar Peters, to Thoralf Räsch in his role as Ludwig van Beethoven, to Leona Schlöder and Peter Rosinsky for providing materials for the video, to the Hip Hop group of the University of Bonn headed by Staicy Stadtler for the performance and to Mauricio Cancilieri who played the piano.
