On the weekend of September 19–21, there was a festive atmosphere on Frankfurt’s Opernplatz: the Polytechnic Society Foundation celebrated its 20th anniversary—and MathCityMap was there!

It was a special honor for us to be part of these celebrations. The foundation recognized the potential of MathCityMap early on and provided us with active support, especially in the early days. We were therefore all the more delighted to be there with our team.

At our booth, we were able to introduce MathCityMap to numerous visitors – from people who happened to be passing by to math enthusiasts to representatives of other projects. Many were interested and enthusiastic about the idea of learning math outdoors.

Away from our booth, the anniversary celebration also offered a diverse and exciting program: numerous initiatives and projects presented themselves and ensured a varied weekend full of exchange, discoveries, and inspiration.

We would like to thank the Polytechnic Society Foundation for the invitation and support. It was a pleasure to be part of this special celebration!

On Friday, June 13, 2025, Frankfurt’s Riedberg Campus once again became a hotspot for science: the Night of Science opened its doors from 5 p.m. until late into the night – and our MathCityMap team was right in the middle of it all with an interactive stand.

Our outdoor location offered the best conditions for our special hands-on offer: the “Night of Science 25” trail. Equipped with measuring materials, a clipboard and the MathCityMap app, many curious guests embarked on a mathematical discovery tour of the campus. The aim was to solve up to 12 tasks – and to look at everyday places such as stairs, benches or building facades through a mathematical lens.

We were delighted with the consistently positive feedback we received – both from those interested in mathematics and from guests who would not describe themselves as fans of maths.

We would like to thank all visitors for the exciting conversations, the interest and the great interaction. Special thanks also go to the Night of Science organization team for making this unique event possible.

See you next year – we are already looking forward to the Night of Science 2026!
