Object:
The mustard seed, though tiny, produces a plant that can accommodate many birds. The
pixel, that little dot on every television and computer screen, acts in much the same way.
(Only instead of growing in size, it multiplies in number.) Here is how it works. The
picture we see on our television is really a series of thousands of dots arranged in a way
that our brain recognizes them as a tree or whatever. If we were to blow the picture up
until we could clearly see the dots or pixels, we would not be able to identify the image
on the screen unless we backed at least twenty to thirty feet. From that distance, the dots
would appear smaller and our brain could translate the dots into the picture.
If you would like to see how this works, put a digital photo on your computer then enlarge it. Soon the edges of the figures become choppy and indistinct but you still know what you are looking at. Keep going. Soon the picture is unrecognizable. It is really quite remarkable -- the pixel -- small but mighty.
