Who Knows?

The theme of Leiden2022 is “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 will show Europe that it is truly a city of science. This is done through local initiatives with international appeal. For example, alongside scientific conferences, 101 neighbourhoods will take part in Leiden2022. The program will also offer a different subject every day, such as bats, hiccups, diabetes, and artificial intelligence. Everything and anything could be explored.

EuroScience Open Forum

In 2022, Leiden will host the 10th edition of the EuroScience Open Forum (ESOF). ESOF is Europe's largest multidisciplinary scientific conference. The conference aims to deliver stimulating content and lively debate around the latest advancements and discoveries in sciences, humanities and social sciences. ESOF brings everyone from leading scientists, early career researchers, business people, policy makers, science and technology communicator to the general public together to find oout more about how science is helping us advance today.
