“What is virtual reality?”, and “How does a search engine work?” – these are some of the questions which are raised in the exhibition “Zeker Weten?!” (“Are you sure?!”) in the Discovery Museum in Kerkrade. For this exhibition, I was interviewed on general questions about science and my research on Virtual Reality, as well as specific questions about how search engines work and why we see what we see on our timelines. These video have become part of an exhibition in the Discovery Museum, starting November 2022.
