Here's a breakdown of key aspects of his definition:
* Paradigm: A paradigm is a shared set of assumptions, theories, methods, and values that define a scientific discipline at a particular time. It provides a framework for understanding and investigating the natural world.
* Puzzle-solving: Normal science operates within the constraints of the established paradigm, focusing on solving specific puzzles and anomalies that arise within that framework. Scientists are not trying to overturn the paradigm, but rather to refine and extend it.
* Focus on detail: Normal science emphasizes precision and meticulousness, aiming to refine and expand upon existing knowledge within the paradigm's boundaries.
* Success: Normal science is considered successful when it successfully solves puzzles and expands upon the paradigm's explanatory power.
Key characteristics of normal science:
* Cumulative: It builds upon previous knowledge, adding to the existing body of scientific understanding.
* Constrained: It operates within the confines of the dominant paradigm, limiting the scope of inquiry.
* Conservative: It resists radical change and challenges to the established paradigm.
Examples of normal science:
* A physicist conducting experiments to confirm the laws of motion within the Newtonian framework.
* A biologist studying the genetic mechanisms of inheritance within the framework of Mendelian genetics.
* A chemist conducting experiments to synthesize new compounds within the framework of established chemical principles.
Note: Kuhn emphasized that normal science is not static. While it primarily focuses on puzzle-solving, anomalies and inconsistencies within the paradigm can eventually lead to scientific revolutions, where a new paradigm emerges to replace the old one.
