Optical illusion is a new horizon of reality perception. Remember — illusions are not magic but a game of imagination…

Ames Room was constructed by an artist and a psychologist Albert Ames in 1946.
One of the Ames illusions made to prove the important role of eye perception experience. The retinal image of a trapeze-shaped window, put on a rod and rotated by a small engine, has a rectangular shape. And the observer receives it as a swinging here and there rectangular window.
National Oceanic and Atmospheric Administration collects pictures of Earth from the 4 satellites. Daylight photos are dull and the night ones bring some interest. The point is that where there’s light there are those who turn it on and the supplying energy. And where there is no light at night, there is no life. Or maybe there is but with no light. The observations have been held since 1993. And if we impose the night frames made ten years ago and the present day’s ones, we’ll see an amazing picture. The color of every point has its own value showing the change in light intensity. The most interesting are: red – night light appeared at this point and there is life now; blue – light (life) is gone here. Russia – the country of the blue points.
- The corner columns of Parthenon in the Acropolis of Athens seem to be of one width when there’s bright sky behind, though their diameters differ.
- The Columns of the Athena’s Temple in Paestum, built in the end of VI ct BC seem to be higher than for real because of optical corrections and they seem to have the same diameter in the lower and medium parts.
- Stonehenge seems to have rectangular stones but it’s just an optical illusion.
- Optical corrections make the Trinity Cathedral of the Trinity-Sergius Lavra more steady and upward-looking. Orthodox temples inside seem higher than outside. This illusion is achieved by walls bending towards the centre of the temple and by steep lines of arcs and domes. Picture: Cathedral of the Annunciation – interior.
- The Belfry of John the Great seems to be falling behind. This illusion deals with the illusory building size change when looking up.
- Campanile Giotto di Bondone is projected in laws of the reverse perspective. This technique strengthens the impression of building’s monumentality.
- The statue of Goddess Athena surrounded by the 2-floor colonnade looks like a real colossus. (Reconstruction of the Parthenon sanctuary in Athens.
- Eyes often deceive us and we see things that don’t exist. This is called optical illusions – errors of eye perception. For centuries people try to overcome them and even use. And we have to say, people are really good at this today.
Architects knew how to fix the perception errors common to a human eye even at ancient times when they built different architectural forms. Optical illusion often deals with the choice of the

In August 28 at 3:59 am (GMT) the space shuttle Discovery started its long way through the cloudy sky. And a bright and unusual trace pictured at this frame remained after the shuttle. The picture was taken from
Sometimes it’s night down here and it’s daylight in the sky. During its 24-h rotation Earth overshadows the Sun and we see sunset at the skyline. When the Sun is down for us,
What illuminates this star formation castle? The Eagle Nebula known to many people shines at different colors at once. Today’s picture was
Most of the photos can’t depict the whole brilliance of the solar corona. The best, of course, is to watch it yourself during the full solar eclipse. Human’s eye can see much more details than a photo-film can capture. Anyway…
