Schrödinger's Cat: The Paradox That Defined Quantum Mechanics
Don't forget to check the recommendations at the end! Schrödinger’s Cat: What Does It Really Mean and Why Does It Still Confuse Physicists? Schrödinger’s cat is not about a cat. It is about a problem. A very precise one: what exactly happens between a quantum system evolving smoothly and a measurement giving a definite result? If we understand this, we understand the limits of quantum theory itself. What Is Schrödinger’s Cat? Imagine a sealed box. Inside, there is a cat, a radioactive atom, a detector, and a mechanism that releases poison if the atom decays. Now, the atom is a quantum system. According to quantum theory, after some time, it exists in a superposition of two states: decayed not decayed If the atom is in a superposition, then the detector is also in a superposition: triggered and not triggered. Which means the poison is both released and not released. Which means the cat is (if we follow the logic strictly) alive and dead at the same time . What...
