Physics, Astronomy & Cosmology / Re: What happens to photons in a room without windows when I switch off the light ?
« on: 23/04/2017 14:45:40 »According to Newton light was composed of particles and his theory was quite successful except that it could not explain interference and so was replaced by Maxwell's, 'waves in an electromagnetic field 'concept this was widely accepted in the scientific community until the advent of the photoelectric effect which could not be explained by waves and so was replaced by the quantum mechanics theory which considered photons to be wave/particles unfortunately this theory in turn could not explain certain anomalies in the energy levels of the Hydrogen atom including the Lamb shift and so was replaced by quantum electrodynamics where photons are seen as modes of excitation of the quantum electromagnetic field.That is one of the stupidest uses of the history of science I've ever seen. The writer lists the scientific history along with the demonstrated progress in science, and then denies that there is a good scientific theory on the topic because there were different theories in the past. That's almost like saying that because a cook changed his recipe for cookies over time, that cook has never baked cookies.
As can be seen there have been several theories not counting Huygens, Fresnel, Democritos and Lucretius to name a few. So it is amply clear that there is no hard and fast theory of light or of photons.
There is no fast theory of photons, despite the writer's desire to promote their own crank theory; there are the detailed and complicated set of theories that make up contemporary quantum theory. People interested in that theory should turn to other sources than the writer of that garbage above.
