ABOUT A.I.: Robots and computer networks are always evolving intelligent consciousness in popular science fiction. But while modern scientists have made great strides in building computers that can mimic logical thought, they still haven't cracked the code of human emotion and consciousness. There are two prevailing schools of thought on artificial intelligence. Proponents of "strong AI" consider that all human thought can be broken down into a set of mathematical operations. They expect that they will one day be able to replicate the human mind and create a robot capable of both thinking and feeling, with a sense of self -- the stuff of classic science fiction. Think of the robot Number Five from the 80s movie Short Circuit, who suddenly realized, frightened, that he could be "disassembled" by the scientists who made him. "Weak AI" proponents expect that human thought and emotion can only be simulated by computers. A computer might seem intelligent, but it is not aware of what it is doing, with no sense of self or consciousness.

WHAT ARE PIXELS: "Pixel" is short for picture element, and represents a single point in a graphic image. Graphics monitors display images by dividing the screen into thousands (or millions) of pixels, arranged in rows and columns. A megapixel equals one million pixels. Pixels are a measure of digital image quality: the more pixels, the better. The modern digital camera works on the same principle as a conventional camera, but instead of focusing light onto a piece of film, it focuses it onto an image sensor array -- called a charged coupled device (CCD) -- made of tiny light-sensitive diodes that convert light into electrical charges. It turns the fluctuating waves of light (analog data) into bits of digital computer data. The more sensors that are packed onto the CCD's surface, the higher the pixel count, and the higher the resolution of the final image.
