Quote from: The Spoon on 27/08/2021 20:35:05Utter nonsense. Light is electromagnetic radiation. Are you denying that a light dependent resistor works because there are no rods and cones? What about a CCD or CMOS detector?They do work and we can see that. Can a CCD or a CMOS see light do non living things see light NO we see light we have a brain I hope. The brain sees light by the means of our eyes and that is by the direct source or by the means of a monitor.
Utter nonsense. Light is electromagnetic radiation. Are you denying that a light dependent resistor works because there are no rods and cones? What about a CCD or CMOS detector?
If you are using a monitor, how was the light detected? CCD, CMOS, LDRs all react to light without human intervention.

Photons are leaving the monitor screen and our eyes and brain make the light from that energy. Photons are energy receptive cells convert that energy into an image what we call light.
If on-shell photons were not real, we'd have a hard time explaining many experiments. We'd also have general hard times explaining obvious phenomenon like the background radiation.
How on earth do you think they get to the monitor? You 'philosophy' is idiotic.
Dictionary.com defines light as, "the natural agent that stimulates sight and makes things visible." The natural agent in question is photons. That makes photons light. Take note that "sight" and "light" are not synonyms.
is it true that without light receptive cells light is not light but only photons/energy.
is it true that without light receptive cells light is not light but only photons/energy.No. Light is a physical phenomenon. Sight is (one of the possible) perceptions of that phenomenon.
Without eyes or a brain, it will remain as energy not light.
Without eyes or a brain, it will remain as energy not light.That contradicts the dictionary definition.
Photons are energy we can see a very small amount of that energy the very large part we can not see is not light but photons at a different frequency. So if we had no eyes the photons that we could have seen will remain as just energy and not light. It takes eyes to see without eyes and a brain all photons remain as energy and not light.
That, again, contradicts the definition of light. Supply a reputable source that backs up your stance if you disagree. I have Dictionary.com and Britannica on my side so far.

Yoy were referring to phhotons as you well know - dont obfuscate. The monitor is generating an image - in this example of something picked up by a camera. You seem very 'box' like.
I guess we do need some research
So to sum up photon + object + eye = light. Photon + object = energy no light. What do you think?
Royal "we".
