5 Απρ 2024 · According to this synthetic conception, a scientific theory is an organised set of models and propositions, some of which are laws, which assert that some things instantiate properties and structures represented by the models of the theory.

A scientific hypothesis is an inferred explanation of an observation or research finding; while more exploratory in nature than a theory, it is based on existing scientific knowledge. A scientific law is an expression of a mathematical or descriptive relationship observed in nature.
