Erwin Schrödinger's Thought Experiment
Austrian physicist Erwin Schrödinger is most famous for his thought experiment involving a cat. He imagined placing a cat in a box with a device that had a 50% chance of releasing poison after an hour. Schrödinger highlighted the paradox where, until the box is opened, the cat exists in a superposition of being both alive and dead simultaneously.
