Scientific theory
Meaning
A Scientific Theory is a model or framework for describing the behavior of a related set of natural or social phenomena. It originates from, and is supported by experimental evidence (see Scientific Method). A Scientific Theory is meant to be a formalized expression of all related accepted scientific evidence up to the point of its creation. A Scientific Theory must be falsifiable, and thus is treated as fact only for the period in which its truthfulness is not disputed with repeatable observations.
Scientific Laws
A widely accepted scientific model which is seems absolute, and has never been disproved by repeatable observations is considered a Scientific Law. Examples of Scientific Laws include Boyle's Law, Evolution (change in allele frequency over time), and the conservation laws in classical mechanics. Laws are typically a single mathematical equation, and provide the foundation for problem solving in the Natural Sciences.
