Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena. [ 1 ] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates.
Kōkichi Sugihara (Japanese: 杉原厚吉, born June 29, 1948, in Gifu Prefecture) [1] [2] is a Japanese mathematician and artist [3] known for his three-dimensional optical illusions that appear to make marbles roll uphill, [4] [5] pull objects to the highest point of a building's roof, [6] and make circular pipes look rectangular.

Hering illusion. The Hering illusion is one of the geometrical-optical illusions and was discovered by the German physiologist Ewald Hering in 1861. [1] When two straight and parallel lines are presented in front of a radial background (like the spokes of a bicycle), the lines appear as if they were bowed outwards.
Since, at first sight, the graphs appear similar, the two illusions are occasionally confused. But the scintillating illusion does not occur with an isolated intersection, as is the case for the Hermann grid; observations suggest that a minimum of 3 × 3 evenly spaced intersections with superimposed discs are required to produce the effect.

The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. [1] It is a simple wire-frame, two dimensional drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side.
