Scientific laws are typically conclusions based on repeated scientific experiments and observations over many years and which have become accepted universally within the scientific community. A scientific law is "inferred from particular facts, applicable to a defined group or class of phenomena, and expressible by the statement that a ...
A scientific theory differs from a scientific fact or scientific law in that a theory seeks to explain "why" or "how", whereas a fact is a simple, basic observation and a law is an empirical description of a relationship between facts and/or other laws.
The definition of a scientific fact is different from the definition of fact, as it implies knowledge. A scientific fact is the result of a repeatable careful observation or measurement by experimentation or other means, also called empirical evidence. These are central to building scientific theories.
While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in natural terms. [127] [128] "Scientific fact and theory are not categorically separable", [129] and evolution is a theory in the same sense as germ theory or the theory of gravitation. [130]
Van Gogh's "The Starry Night" seems to follow a mathematical theory describing fluids in nature. He couldn't have understood the equations, which came about decades after his death.
The law is falsifiable and much more useful from a scientific point of view, if the method to detect the neutrino is specified. [42] Maxwell said that most scientific laws are metaphysical statements of this kind, [43] which, Popper said, need to be made more precise before they can be indirectly corroborated.
Scientific evidence is closely related to empirical evidence but not all forms of empirical evidence meet the standards dictated by scientific methods. Sources of empirical evidence are sometimes divided into observation and experimentation , the difference being that only experimentation involves manipulation or intervention: phenomena are ...
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, [1] although scientists also use evidence in other ways, such as when applying theories to practical problems. [2] Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method.
