👉 In physics and mathematics, a superposition principle states that at any instant in time, the probability of an event occurring is not determined by the current state of the system, but instead depends on all previous states. This principle is particularly useful for describing phenomena such as quantum mechanics where particles can be described as having wave-like properties. In other words, if a particle has a certain energy E and it has already been observed to have a certain momentum p, then its probability of experiencing that momentum at any
