If it is, post some physics, instead of sepulchral pronouncements, such as:

I was, because what I said is correct, "sepulchral" or not. PS, please translate sepulchral into a meanigful physics term.

From my own pit of questions, could you translate "photon" into meaningful physics terms and describe how a single "photon" in a double slit experiment gets to its final position on the screen?

In every way possible?

Tiny effect
In 2014, a team led by Sinha used the path-integral formulation of quantum mechanics to calculate the effect of non-classical paths on the interference pattern from three slits. The calculations revealed that the deviation from a simple superposition depends on the size of the de Broglie wavelength of the particle. The effect is tiny for electrons and visible light – being one part in 108 and one part in 105 respectively – which is too small to detect.

However, they did show in 2014 that the deviation is much larger for microwave photons and now Sinha and colleagues have done an experiment that has measured this deviation for the first time.

Instead of using three slits, the team did a “triple slot” experiment whereby the interference pattern is created when quantum particles encounter three barriers (slots) to their propagation. Slots rather than slits were used for practical reasons related to the size and cost of the experiment.

The team measured a deviation of 6% from the superposition principle thereby confirming the significance of non-classical paths. They also point out that their observation has implications for radio astronomy, where arrays of detectors are used to create large radio telescopes using the principle of superposition. Describing their results in the New Journal of Physics, the team points out that such deviations could affect observations made using arrays, particularly in precision astronomy experiments.
