Count The Number of Photons

These images depict particles of light entering the eye. The four monitors are connected to the PC as a metaphor for the brain through cables stretched like the optic nerves.

A particle of light is called a photon. Mass is zero, size and charge are zero. Even in a dark room similar to a movie theater, 400 billion photons fall on your fingertips in just one second. Under sunlight, the number is 100,000 times. Our “seeing” is realized by the vast number of photons colliding with the ground, floors, walls, trees and people, and they continue to reflect and refract an unimaginable number of times. After 150 million kilometers of travel from the sun, new photons arrive on the ground one after another and continue to interact. Our bodies are immersed in such a space. Part of it reaches the eyeball, hits the retina through the lens, and the collision energy is converted into electrical energy and transmitted to the optic nerve. Imagine the number of photons flying in front of you.
