In order to debunk the theories regarding the interpretation of the behavior of atoms  in quantum mechanics, renowned scientist Erwin Schrödinger proposed a thought experiment – popularly known as The Schrödinger’s Cat Experiment – which went on to make waves in the world of science. The experiment involved the placing of a cat in a steel box, along with a vial of poison, a Geiger counter, hammer and a radioactive substance. When the radioactive substance decays, the Geiger counter detects it and the vial of poison breaks by the action of the hammer. But given the random nature of radioactive decay, it is implausible for scientists to predict the certainty of it decaying. Therefore, the cat’s life largely depends on whether the radioactive substance decays or not.  Simply put, according to Schrödinger, the cat’s state is unknown to the observer –that is the cat is considered to be both dead and alive at the same time until the box is opened by the observer. It ascertains the fact that the atom exists in a state of superposition, which is both decayed and non-decayed at the same time.  Schrödinger famously used this cat analogy to best describe the nature of wave particles in quantum mechanics.
