The academic year 2022 – 2023 provided a new start for the nearly 8,000 students and 500 lecturers at the Faculty of Science after the covid pandemic. Having been forced to work from home, to follow online classes (with the exception of laboratory work) and to interact with other students via social media, has demonstrated once more the importance of being on campus all together. We also learned that alternatives are possible, and that we are lucky to have very motivated teams of lecturers and students.
