Wave-Particle Duality Through Systemic Functional Linguistics [8]

Edelman (1992: 215):

Quantum theory is the most generally applicable of all theories. In dealing with enormous energies and very small particles, this theory has revealed behaviour that confounds ordinary expectations. For example, one particle cannot be identified as distinguishable from another. Particles show duality of behaviour: Under one set of circumstances they are best described as waves, in others as particles. Indeed, as Max Born first suggested, the fundamental wave function ψ in the Schrödinger wave equation, when taken as an absolute value and squared, is a measure of the probability of finding a particle in a given position of space — anywhere!

As previously explained, from the perspective of Systemic Functional Linguistics, wave-particle duality is the duality of potential and instance.  Probability measures potential (wave), statistical frequency measures instances of that potential (particles).
