Standard interpretations of quantum mechanics typically begin by drawing a parallel between patterns produced through classical waves and the discrete scattering patterns observed in quantum experiments.

This parallel leads to a basic premise that underpins various attempts to make sense of quantum phenomena: The idea that an explanatory model of quantum theory can be created out of some type of model where all particles have a dual existence, as both particle and wave.

Whether it is 'wave-function collapse', pilot waves, or the apparently different 'multiverse' - the background agenda appears to be the same: Explain how the non-local aspects of interference can be coupled with the discrete and localised nature of particle interactions, and you can explain quantum mechanics.

Everyone is familiar with the argument: The essential point is illustrated in the classic double-slit experiment where we see discrete particles that by common-sense could only pass through one aperture or the other, scatter one-by-one into patterns that are identical to patterns produced by waves by passing through both apertures simultaneously.

The mathematical formalism of quantum theory, however, is not helpful. It does not literally describe waves that operate as classical waves that propagate in space and time.

Could it be that this idea of wave-particle duality is a dead end, a system of epicycles on epicycles that evolves because we have missed something at the outset?

So is there another approach? One clue that fascinates me starts with the work developed back in 1923 by American physicist William Duane. So lets, start...
