Reaching out to the local and regional communities establishes a strong base and is geared toward getting people excited about the sciences. Exhibitions and film festivals are organized to capture the interest of the public in and around Heidelberg. Experiencing and understanding mathematics and computer science is the motto of the Mathematics Informatics Station (MAINS), which opened in 2017. Various activities for all ages are organized throughout the year: interactive and photo exhibitions, film screenings, lectures and much more. MAINS is a project of the Heidelberg Laureate Forum Foundation, which strives to show how exciting mathematics and computer science can be and how important their role is in today’s world. Additionally, each year an exhibition with a mathematical or computer scientific core runs parallel to the HLF as part of the accompanying program.
