Simple alternative model of the dual nature of light
... Although a model based upon hypotheses n° 1-5 in section 2 may look simplistic and naïve, it might be possible to define a thought, or Gedanken experiment in order to verify or refute it. For that purpose the latter should incorporate one source of single-photons, using for instance the technique of ...
