International Day of Mathematics

«Playing with Math» was the theme of this year’s International Day of Mathematics on March 14th. Several scientific institutions, including the University of Vienna, the Vienna University of Technology, and the Austrian Academy of Sciences, collaborated to explore intriguing mathematical concepts in a playful manner.

Axel Kittenberger and Noemi Naujoks demonstrated how a computer tomograph works and explained the fascinating mathematics behind it. They showcased the Origami Tomograph developed by CSC, which reconstructs a transparent 3D object from light projections. A special highlight was a quiz that encouraged participants to play the role of a tomograph and guess the underlying object from projection data.
