Greeks History
Optical illusions were first used by the Greeks. They built their temples so that the roof was slanted. This gave the illusion that the temple was actually standing straight. They also made the columns bulge so that from a distance they would look perfectly proportioned. In the course of history, people have encountered illusions in many ways. Many of these illusions appear in very common, everyday experiences.
An example of an identification of such an illusion occurred when L. Herman was reading a book on sound by John Tyndall. He saw grey smudge spots in the intersections of spaces among the figures that Tyndall had arranged in a matrix. The same intensity of light is reflected all the way along the white spaces in the grid but the intersections appear gray.
These optical illusions which occur in our everyday lives have become the subject of study by psychologists. This field involves aspects of the arts, architecture, and even physiology and physics. The study of illusion includes both how we perceive what is around us and how we project our own concepts onto what we see.
Today we see optical illusions everywhere when we look at a t.v. The pictures are not really moving. It is really many pictures moving so fast that our brain cannot comprehend each individual picture. Also with computers, magazines, and t.v we see millions of colors but it is really just dots colored red, green, and blue. If you look closely enough at a magazine or t.v or computer screen you can see the little dots.
