Who Knows

The theme of Leiden2022 was “Who Knows”. This reflects the current zeitgeist, in which opportunism and deepfakes gnaw at scientific integrity and truth-finding. “Who Knows” is about who owns knowledge nowadays? Who determines what is true, and who knows what the future will look like?

From Local to International

In 2022, Leiden showed Europe that it is truly a city of science. This was done through local initiatives with international appeal. For example, alongside scientific conferences, 101 neighbourhoods that took part in Leiden2022. The program also offered a different subject every day, such as bats, hiccups, diabetes, and artificial intelligence. Everything and anything had been explored.
