The dynamic mechanism underlying science involves the codification of observations around some presumed "process in nature" or "natural law" and the belief in that causal system until multiple converging evidence overwhelmingly leads to a correction, after which a different underlying process is accepted as causing the sense data, such that the new perspective is even more coherent than before. Such a revolution occurred when astronomy shifted from the earth-centered solar system of Ptolemy to the sun-centered system advocated by Copernicus. A metaphor for a paradigm would picture people probing the bottom of a muddy lake with poles, trying to identify what fell into the lake. Some observations result in high spots, some indicate muddy bottom. After many observations someone comes up with an idea about the nature of what it must be (e.g., a steam shovel). This perspective is the "paradigm."
