“Why is the sky blue?”, “What is a black hole?”, 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.
