This video from UK-based Open University uses clever animation to describe six of the most famous thought experiments: Zeno’s Achilles & The Tortoise, Barjavel’s Grandfather Paradox, Searle’s Chinese Room, Hilbert’s Grand Hotel, Einstein’s Twin Paradox, and Schrödinger’s Cat. My personal favorites have always been the Chinese Room and the Grandfather Paradox, but I can’t help but think that Schrodinger’s Cat reminds me of the Bonsai Kitten we posted about last week. Multiple states of being.
