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.

MAINS closed until further notice

In order to reduce contact and help contain the rate of new infections, the MAINS and the exhibitions will remain closed until further notice. As soon as we can reopen, we will inform you on our website and social media channels. Please note that the opening hours on the website will not be individually adjusted due to the temporary nature of the closure.

We hope to be able to welcome you back to the MAINS soon and wish you all the best until then.

Virtual Film Festival

The 8th Film Festival Mathematics – Computer Science that was planned for November 2020 unfortunately had to be canceled due to the pandemic. In response, the HLFF invited any interested to the Virtual Film Festival, with four screenings from March 14–29, 2021. The films selected threw a spotlight either on the life and work of outstanding scientists or on social discourse surrounding current issues rooted in mathematics and computer science. Special guests and the films’ directors were available for questions following the screenings.


No End in Sight

New exhibition planned for Spring 2021

Every day we use words like infinite, without end or eternal, but what "infinite" really means remains a mystery. Set to visit the MAINS in 2021, 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.

The new exhibition will open as soon as it is safely possible. More information to follow.


Cartoon Exhibition

At the MAINS until August 29

The MAINS and the exhibitions will remain closed until further notice. 

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.


La La Lab digital

Join us on our virtual tour through the exhibition "La La Lab - The Mathematics of Music". 15 informative and entertaining videos in German explore selected stations and offer a clear introduction of the exhibition's topics. Watch them at home or on the go, and you can even try out many stations directly on your browser. All videos can be found on our MAINS YouTube channel.


The exhibition’s opening in the MAINS had to be postponed in response to the pandemic and is currently planned for the fall of 2021. "I AM A.I." takes an imaginative look at artificial intelligence and until the exhibition can be seen live in Heidelberg, the website allows visitors to take an interactive tour of some of the exhibits. The exhibition was developed and implemented by IMAGINARY and funded by the Carl Zeiss Foundation.
