The World Science Festical is an event that seems to bring scientists from different fields with highly interesting or intriguing thoughts and ordinary humans together once a year. I don't really know much more about it than the Wikipedia article says. But after wathing several of the panel recordings on YouTube I feel like sharing some of the (to me) most interesting topics.
This is just a small selecltion from similar videos that are way worth watching. The videos on their YouTube channel are sorted into playlists by topic category.
