"The Structure of Scientific Revolutions" is a book by Thomas S. Kuhn published in 1962. It introduces the concept of paradigms, which are the frameworks of theories and practices that define scientific disciplines. Kuhn argues that science progresses through a series of phases: normal science, crisis, and revolution, where a prevailing paradigm is replaced by a new one. Kuhn's work challenges the traditional view of scientific progress as a linear accumulation of knowledge. Instead, he suggests that scientific advancements occur through paradigm shifts, which are often triggered by anomalies that cannot be explained by existing theories. This leads to a re-evaluation of scientific understanding.
