A paradigm shift is a fundamental change in the basic concepts and experimental practices of a scientific discipline. It is a concept in the philosophy of science that was introduced and brought into the common lexicon by the American physicist and philosopher Thomas Kuhn .
The paradigm shift does not merely involve the revision or transformation of an individual theory, it changes the way terminology is defined, how the scientists in that field view their subject, and, perhaps most significantly, what questions are regarded as valid, and what rules are used to determine the truth of a particular theory.
An example of a paradigm would be the geocentric model of the universe; an example of a paradigm shift would when the heliocentric model began taking over due to irrefutable evidence (largely from Galileo Galilei, Johannes Kepler, and Isaac Newton). In Kuhn's model, these three would be revolutionary scientists, because they changed the model.
Thomas Kuhn [10] described how a paradigm shift is a wholesale shift in the basic understanding of a scientific theory. Examples in science include the change of thought from miasma to germ theory as a cause of disease. Building on this work, Giovanni Dosi [11] developed the concept of 'technical paradigms' and 'technological trajectories'. In ...
The Oxford English Dictionary defines a paradigm as "a pattern or model, an exemplar; a typical instance of something, an example". [11] The historian of science Thomas Kuhn gave the word its contemporary meaning when he adopted the word to refer to the set of concepts and practices that define a scientific discipline at any particular period of time.
The Copernican Revolution was the paradigm shift from the Ptolemaic model of the heavens, which described the cosmos as having Earth stationary at the center of the universe, to the heliocentric model with the Sun at the center of the Solar System.
