Kuhn and paradigm shifts in science
The term paradigm shift was introduced by Thomas Kuhn in his highly influential landmark book, The Structure of Scientific Revolutions. Kuhn shows how almost every significant breakthrough in the field of scientific endeavor is first a break with tradition, with old ways of thinking, with old paradigms. For Ptolemy, the great Egyptian astronomer, the earth was the center of the universe. But Copernicus created a paradigm shift, and a great deal of resistance and persecution as well, by placing the sun at the center. Suddenly, everything took on a different interpretation. The Newtonian model of physics was a clockwork paradigm and is still the basis of modern engineering. But it was partial, incomplete. The scientific world was revolutionized by the Einsteinian paradigm, the relativity paradigm, which had much higher predictive and explanatory value. Until the germ theory was developed, a high percentage of women and children died during childbirth, and no one could understand why. In military skirmishes, more men were dying from small wounds and diseases than from the major traumas on the front lines. But as soon as the germ theory was developed, a whole new paradigm, a better, improved way of understanding what was happening made dramatic, significant medical improvement possible.
