Wanted Dead or Alive

What is the difference between interaction and measurement? Erwin Schrödinger has achieved great contributions in quantum mechanics. However, he is best known for his thought experiment known as “Schrödinger’s Cat”, a challenge to the traditional Newtonian view of the universe as deterministic.

Imagine a cat in a sealed box with a device that has a 50% chance of killing the cat. According to quantum mechanics, the cat would be in a superposition state, which means that it would simultaneously exist in both a living and a dead state until the box is opened and the state is observed. The concept of wave-particle duality and the role of the observer in determining the outcome of a quantum event are demonstrated.
