Researchers' Night at the Czech Technical University in Děčín is traditionally associated with the Open Doors Day. For visitors, we have prepared physical experiments, lectures, insight into the world of AI, virtual reality or 3D printing in a newly equipped laboratory. Dopravka in Děčín made available a unique car simulator, which was of great interest. Thank you to all the participants, which were almost 500 this year! We would like to thank the Ústí Region and councilor Jindřa Zalabáková for the financial support, who came to see all the exhibits and try them out for herself.
