Theorie

Theorie, or theory, is a coherent set of principles and propositions that explains a broad range of phenomena and helps predict future observations. Theories integrate existing knowledge, identify relationships, and provide a framework for understanding how different elements interact. They differ from hypotheses, which are testable statements about specific cases, while theories are larger explanatory structures. Theories are not static truths; over time they are refined, extended, or replaced in light of new evidence.

In science, theories are supported by evidence from observations and experiments and must be testable and falsifiable. They generate testable predictions and aim to unify disparate findings under a single account. Examples include the theory of evolution, the theory of gravity in its modern form (general relativity), and quantum theory. In addition, fields such as game theory study strategic interaction and decision-making using theoretical models.

In mathematics, theory denotes a systematic body of results derived from accepted axioms, such as number theory or graph theory; here the term reflects a field of study rather than empirical testing. In the social sciences and humanities, theories provide explanatory models of behavior, institutions, and social processes. Theories are evaluated by explanatory power, coherence, scope, and their ability to generate new predictions, while their specific assumptions may be debated. Overall, a theory serves as a tool for organizing knowledge, guiding inquiry, and interpreting data within a coherent framework.
