IDTIMWYTIM: Schrodinger's Cat
Austrian physicist Erwin Schrödinger published his famous thought experiment. He wanted to point out a problem in the interpretation of a new physical theory, quantum mechanics. In his scenario, there is a cat placed in a box together with a radioactive material, poison, and a Geiger counter. According to quantum mechanics, the cat can be alive and dead at the same time.
