Schrödinger's cat

                  Schrodinger's cat is a thought experiment, sometimes it is  described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. It is a scenario where the cat is both dead and alive  at the same time ,
in quantum mechanics this state is known as superposition.





The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation. In this interpretation, every event is a branch point. The cat is both alive and dead—regardless of whether the box is opened—but the "alive" and "dead" cats are in different branches of the universe that are equally real but cannot interact with each other.
