Wolf DeVoon Posted June 5, 2007 Share Posted June 5, 2007 I have a few minutues before I get on a plane, and I'd like to take another stab at explaining what a CCD is, using the metaphor of holography again. It's interesting to note that most holograms are monochrome. If you physically chop a piece off, you still see the whole holographic image, because every bit contains all of the information. Human memory is analogous. It exists diffusely in the brain -- not in a discrete place like a magnetic disc or DVD. I remember seeing a Soviet hologram in 1979 that was very dark. Nice image but obscure and a little fuzzy. I suspect many human concepts are dark and fuzzy, too.Anyway, the way you make a hologram is to paint the subject with a coherent beam and use the same beam as a reference to record the resulting interference pattern. Let's say one is painting the ostensible world with shape as a CCD. Triangles, squares, circles, rounded objects etc jump out, omitting their color, function, relative size and whatnot. This is how semiology works. An octagon means stop. An arrow means proceed that way. The CCD of shape also helps us form memorable and meaningful concepts about animals, plants, interior design, architecture, and fat/skinny people.Applied to abstract thought, we paint with CCDs, especially predicate logic and the illuminating reference known as context. I don't have time to do a good job of explicating this today. But imagine what happens to a man who routinely paints his mental world with Jesus or Allah or snarky skepticism.Over and out for a while. Goin' home to the jungle, where bandwidth is like a leaky garden hose.W. Link to comment Share on other sites More sharing options...
