"The most amazing thing is that it’s not like seeing light. It’s almost a feeling, at the threshold of imagination". They had 3 volunteers for 2400 trials. Do you think they *learned* how to sense photons?
Some evidence that human beings can detect single photons of light!! https://www.nature.com/news/people-can-sense-single-photons-1.20282 … (via @fulhack ).

Don't know. Interesting question.

Animals seem to have various 'subconscious' sensitivities to light. Though not of the same nature, this is an interesting other case:https://news.mit.edu/2016/visual-stimulation-treatment-alzheimer-1207 …

Quite plausible biologically, I think! Reminded me of Aldrin's Apollo 11 "cosmic ray flashes" (though that's probably a different process)

Is there a good treatment anywhere of what “single photon” propagating waves actually are? Should I just think of a coherent beam where the average occupancy of every mode is O(1)?

Oh wait, I still remember developing an electronic circuit with avalanche diode to amplify signal caused by single photon. Does this imply human possess equivalently sophisticated organism? Wow.

"given that more than 90% of photons that enter the front of the eye never even reach a rod cell, because they are absorbed or reflected by other parts of the eye".. didn't know
