👉 Emmetropy is a concept in quantum mechanics that describes the probability of finding a particle at a specific position or energy state within a system. It was introduced by physicist John T. Emmett in 1978. The concept of emmetropy is based on the idea that the total energy (E) of a system can be expressed as a sum of its kinetic energy (K) and potential energy (V), which are related by the equation: \[ E = K + V \
