"Isn’t this picture worth of thousand of words? In compliance with the holographic principle, if you have a computer with a normal size monitor, you will be able to extract 3 x 10⁶⁵ bit of information from this picture. The holographic principle, which has not been proved so far, affirms that there is maximal quantity of information, containing in the spheres, adjacent to this or that surface. Consequently, contrary to intuitive conception, quantity of information, contained in the room, depends not on the volume of the room, but on the square of the walls, bounding it. The principle originated from the idea that the Planck length determines one of the sides of the surface, which can contain only 1 bit of information. The Planck length is a typical distance, on which the principles of quantum mechanics begin prevailing over the laws of classical gravitation. The existence of this limit was postulated for the first time by physicist Gerard ""t Hoof in 1993. It can be also obtained from the generalization of the following statement, which at first glance refers to entirely other sphere: the quantity of information, contained in the black hole, shall be determined not by the volume, but by the area of surface of its events horizon. Term “Holographic” originated in analogy with a hologram, when three-dimensional images are created by means of light transmission through a flat screen. But some people, looking at this picture, can say: what they really see is not 3 x 10⁶⁵ bit of information, but a teapot. "
