Schrodinger´s Cat

Erwin Schrodinger was an Austrian physicist who created the thought experiment known as Schrodinger's Cat. A cat is (hypothetically) put into a soundproof box with a small amount of radioactive material and a Geiger counter (that detects radioactive material). As the amount of material is very small, there is only a 50% chance that it will be detected. If it is detected, a hammer will smash a poison inside the box and the cat will die. Because it is impossible to know if the cat is alive or dead without opening the box, it is both (dead and alive). Although this outcome does not make much sense for a cat, it helps explain the concept of quantum superposition according to the Copenhagen Interpretation, which states that a system exists in all possible configurations until it is observed and must 'collapse' into only one.
