Manuscripts/Mixed Material Journal by Alexander Graham Bell, from July 19, 1901 to August 31, 1901
moving into the shadow of the night. We would see the world as it would look from a distance in space. But this is not related to our own experiences. To our senses the world is at rest, and the days and nights move over the surface. I think, therefore, that a moving picture representing the world — or the United States — (the same thing perhaps!) at rest, and a shadow creeping over it from right to left would be more useful. Then night would cover the whole continent until a strip of sun rise would appear on the eastern edge and the shadow then gradually pass off to the left leaving the continent in day.
SYMBOLICAL MOVING PICTURES. Just as in composite photography it is not necessary that natural objects alone should be photographed — a composite of graphical symbols of any sort being possible — so, speaking abstractly, if we represent any series of facts by arbitrary, but graphical symbols, then a rapid succession of photographs projected upon the same screen would cause these symbols apparently to move — they would grow longer or shorter, thicker or more slender; they would become darker or gradually fade away in accordance with the graphical principle of symbolization. I am inclined to think that we may have here a new method of scientific research specially adapted for the examination of complicated cases where correlated conditions are found.
