To make a hologram, the object to be photographed is first bathed in the light of a laser beam. Then a second laser beam is bounced off the reflected light of the first and the resulting interference pattern (the area where the two laser beams commingle) is captured on film.
When the film is developed, it looks like a meaningless swirl of light and dark lines. But as soon as the developed film is illuminated by another laser beam, a three-dimensional image of the original object appears. The three-dimensionality of such images is not the only remarkable characteristic of holograms. If a hologram of a rose is cut in half and then illuminated by a laser, each half will still be found to contain the entire image of the rose.
Indeed, even if the halves are divided again, each snippet of film will always be found to contain a smaller but intact version of the original image. Unlike normal photographs, every part of a hologram contains all the information possessed by the whole. The "whole in every part" nature of a hologram provides us with an entirely new way of understanding organization and order.
An apple tastes like an apple how many ever pieces you may cut it to. It retains its intrinsic taste in every part.

It opens a new way of looking at.
Ya. It might lead us to the old way of looking at things too. I mean, the advaita philisophy of "There is poornam (completeness) everywhere. If you remove poornam from poornam there still will be poornam."
ReplyDeleteThis might be some kind of deeper reality. Deeper than our conscious being.
i am at total loss. followed only upto the physics part and recollected it and found it interesting :)
ReplyDeleteGood one Ramesh... KIU
