The Festival
The International Science Festival – Geist Heidelberg is aimed at the general public and brings greats of national and international research to Heidelberg every year.
Our mission
The DAI Heidelberg’s Science Festival brings groundbreaking and current scientific findings out of the laboratories and into the hands of interested citizens. It stands for scientific enlightenment and education, diversity of research and a democratically engaged society and is the European answer to the New York World Science Festival.
Our topics
Every autumn, renowned scientists, Nobel laureates, world-famous authors and talented early-career researchers engage with an audience of interested members of the public and experts to discuss the pressing issues of our time, including topics such as evolutionary research, cosmology, biology, medicine, psychology, neurology and digitalisation, as well as the interrelationships between science and society.
Our guests
With a top-notch lineup, the festival has attracted thousands of interested people from Germany and abroad to Heidelberg each year for more than a decade to share amazing and groundbreaking scientific discoveries.
Our guests in recent years have included, amongst others, Nobel Laureates Sir Richard Roberts, Reinhard Genzel, Sir Paul Nurse and Didier Queloz, as well as the Dalai Lama, Marina Gedeck, Lawrence Maxwell Krauss, Lisa Randall, Eric Kandel, Noam Chomsky, Dame Jocelyn Bell Burnell, Vinton Cerf, Richard Dawkins and many more!
