KOSMOS
Violinist and climate composer Tim Kliphuis draws his inspiration from five top Dutch scientists in paleo-oceanography, biology, physics, philosophy and astronomy. That fascination grew not only into a series of podcasts, but also into his brand new work Kosmos. The performance is accompanied by stories by Erik van Sebille, professor of Oceanography and Climate Science at Utrecht University. Van Sebille examines ocean plastic and the role of scientists in society. Relevant and compelling!
