Definition: Stevens' Law is a fundamental principle in quantum mechanics, which states that the energy of a quantum system can be described by its wavefunction. The energy levels are quantized and are determined by the values of the wavefunction at different points in space-time.
In simpler terms, if you have a particle with an energy level represented by a function f(x), where x is some variable representing position or momentum, then the total energy of the system will be given by:
E = ∫
