The Probabilities Of The Wavefunction Viewed Through Systemic Functional Linguistics

Penrose (2004: 511-2):

There is something that should be emphasised here. One could imagine that a little spot on the screen comes about from time to time, when the local intensity of the wave reaches some critical value or, rather, that there is some probability of a little spot appearing on the screen, this probability increases as the intensity of the wave increases. Nice try! But as I have formulated the two-slit experiment (in its idealised form) above, this simply will not work. For if it were just a matter of individual probabilities at individual places, we should expect that sometimes two spots would appear on the screen, at widely separated locations where the intensity is appreciable, with just the one wavefunction describing the emission of a single particle at the source.

From the perspective of Systemic Functional Linguistic Theory, the wave grades the probable locations of a particle — not the probable particles of a location.
