sciencely transforms the Bahnhof der Wissenschaften, Unter den Linden in Berlin-Mitte into a space of discovery. You can playfully explore the exhibition of the Humboldt-University in the subway station: Discover with sciencely special motives of the exhibition and their meaning. If a subject interests you, it contacts you and you can chat with it - during your visit to the station, but also on the road and everywhere. Via image recognition or through your interactive swipe gesture selection following the Tinder mechanics, an exciting, funny or even emotional chat with a motive of your choice begins. Your chat will develop depending on your choice of answers and statements. At the end of your dialogue, you can create a photo of the motive and file it with other objects in your personal collection. Motives of the exhibition, architectural details, monuments and even subway signs will come to life during your discovery in Berlin-Mitte. The exhibition of the Humboldt-University at the Bahnhof der Wissenschaften is dedicated to the Anthropocene. As never before, humans are intervening in the Earth system. Scientists explore the consequences for nature and humans. The illustrations by Nele Brönner in the back track windows on the platform visualize the research on the interactions between humans and nature. The hidden images and word clouds address different environments of the Anthropocene: the atmosphere, sea and ice, life in the city, forest and field. In the spirit of Open Humboldt, we invite you to: discover our geological age, dive into the (en)worlds of the Anthropocene and explore scientific connections with us. sciencely accompanies you on your expedition.
