Photons are finally here. Who knew such a slow arrival was possible? Maybe COVID tunnelling is a phenomenon after all or at least COVID-induced lassitude. Introspection suggests the latter, unreliable as it is. Topics around light are typically taught by a mixture of assertions about light and waves and use of ray diagrams to make predictions. I suggest that a radical overhaul would improve matters.
Can you do a many paths simulation in 2D where there are always symmetrical paths? I find this nicely explains why light appears to travel in straight lines - there's always a mirror image path that cancels the other one out when you sum, except for the direct path.
