Mathematics Informatics Station (MAINS)

Welcome to the

Experience and understand mathematics and computer science! In 2017, the Heidelberg Laureate Forum Foundation opened the MAINS, right near the Heidelberg central train station. Throughout the year, we offer various activities for all age groups such as interactive exhibitions, portrait gallery, film screenings, Science Notes, lectures and much more. Come and see for yourself how exciting mathematics and computer science can be! The MAINS also offers guided tours of the exhibitions for school classes and groups.


Explaining Artificial Intelligence

The time has finally come: beginning January 29, 2022, the interactive exhibition is coming to MAINS and uses images, videos and experiments to explore the core questions surrounding artificial intelligence: How does it actually work? How can it be used? And what are its limits?
Until then, the website offers an interactive tour of some of the exhibits..

The exhibition was developed and implemented by IMAGINARY and funded by the Carl Zeiss Foundation.


No End in Sight

Current exhibition

Every day we use words like infinite, without end or eternal, but what "infinite" really means remains a mystery. The German exhibition "Kein Ende in Sicht" (No End in Sight) of the Mathematikum Gießen invites you to follow the phenomenon of infinity through many interactive experiments.


Cartoon Exhibition

At the MAINS until January 16

Math and humor, it sounds like hot and cold, like day and night, like plus and minus. But around 100 masterpieces by over 40 artists will be on display: There is another way! In the exhibition "Mathe macht lustig", top cartoonists from Germany, Austria and Switzerland take a humorous look at mathematics. Open Thursday to Sunday and on public holidays.


Film Festival

Mathematics – Computer Science

This year’s Film Festival Mathematics – Computer Science took place from October 30 until November 6. An exciting blend of films showcased diverse facets of mathematics and computer science as well as brought the life and work of extraordinary scientists under the spotlight. An expert was on hand to introduce each film and to field questions after the screening.
