In episode #6 we welcome Professor Martin Buhmann (Giessen) of the "Approximation, sampling and compression in data science" programme to speak about the Giessen-based Mathematikum centre. As co-Director of this central German mathematical science centre he is perfectly placed to discuss public engagement with mathematics, how a more "physical" approach can help capture the imagination of the young and old alike, and how to make learning fun.> https://www.mathematikum.de/index.phpHosted by: Dan Aspel (INI Communications Manager)
