Fact in science
Just as in philosophy, the scientific concept of fact is central to fundamental questions regarding the nature, methods, scope and validity of scientific reasoning.
In the most basic sense, a scientific fact is an objective and verifiable observation, in contrast with a hypothesis or theory, which is intended to explain or interpret facts.
Various scholars have offered significant refinements to this basic formulation. Also, rigorous scientific use of the term "fact" is careful to distinguish: 1) states of affairs in the external world; from 2) assertions of fact that may be considered relevant in scientific analysis. The term is used in both senses in the philosophy of science.
