Quantum Flow Through Geometric Channels
Standard quantum mechanics derives the interference pattern from a wavefunction and the Fraunhofer small-angle approximation, with per-slit amplitudes treated as free parameters and perfect dark-to-bright contrast as the idealized prediction. Morphological Physics derives the same pattern from slit boundary geometry — without small-angle approximation, with amplitude computed from physical geometry rather than assumed equal across slits.
The two approaches agree exactly where the textbook approximation holds (N=2 symmetric slits, far field). They diverge in measurable ways as the approximation breaks down: at N≥3 slits, in the near-field regime, and wherever per-slit amplitude variation matters.
Open questions explored here include the N-slit Fresnel regime, the geometry-to-visibility relationship, and quantitative comparison with Tonomura's biprism measurements.
