Former House of Erwin Schrödinger

At this location in Zurich stands the former house of the Austrian physicist Erwin Schrödinger. Schrödinger was one of the first physicists to explain modern quantum mechanics by means of a thought experiment. His most famous thought experiment, known as Schrödinger's cat, describes a closed box containing a living cat, a vial of poison and a radioactive element. As long as the box remains unopened, the cat is theoretically in a quantum superposition between alive and dead.
