"WebFeb 4, 2024 · Normality just means that the probability density of finding a particle in an eigenstate ψ n immediately after you’ve prepared it in the same state, somewhere in the universe, is 100%: ∫ − ∞ ∞ ψ m ( x) ∗ ψ n ( x) d x = 1 m = n. Orthogonality states that, for a given state Ψ, which can be represented as the linear combination. " - Box normalization quantum mechanics
