Falsifiability Falsifiability (or refutability) is the logical possibility that an assertion can be shown false by an observation or a physical experiment. That something is "falsifiable" does not mean it is false; rather, that if it is false, then this can be shown by observation or experiment. Falsifiability is an important concept in science and the philosophy of science. The term "Testability" is related but more specific; it means that an assertion can be falsified through experimentation alone. Falsifiability

The term was coined by Otto Neurath in a series of early 20th century essays on the subject, in which he wrote"According to physicalism, the language of physics is the universal language of science and, consequently, any knowledge can be brought back to the statements on the physical objects." Physicalism

Scientific method Scientific method refers to bodies of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning.

Occam's razor Occam's razor, also Ockham's razor, is the principle that "entities should not be multiplied unnecessarily." It is apocryphally attributed to 14th-century English logician and Franciscan friar, William of Ockham. The principle states that the explanation of any phenomenon should make as few assumptions as possible, eliminating those that make no difference in the observable predictions of the explanatory hypothesis or theory.

The field is defined by an interest in one of a set of "traditional" problems or an interest in central or foundational concerns in science. In addition to these central problems for science as a whole, many philosophers of science consider these problems as they apply to particular sciences (e.g. Philosophy_of_science

This can be said of objects, phenomena, explanations, theories, and meanings. Reductionism
