Paradigm Shifts and Scientific Perception – Thomas Kuhn

„The historian of science may be tempted to claim that when paradigms change, the world itself changes with them. Led by a new paradigm, scientists adopt new instruments and look in new places. even more important, during revolutions, scientists see new and different things when looking with familiar instruments in places they have looked before. It is rather as if the professional community had been suddenly transported to another planet where familiar objects are seen in a different light and are joined by unfamiliar ones as well.“

Thomas Kuhn quote about paradigm shifts and how scientists perceive the world

Thomas Samuel Kuhn (1922–1996) was one of the influential philosophers of science of the 20th century. In his major work, “The Structure of Scientific Revolutions,” he described the development of science as a sequence of periods of normal science interrupted by scientific revolutions. He is particularly associated with the concept of the paradigm shift and with the idea that different paradigms may be incommensurable.

"Individuals who break through by inventing a new paradigm are almost always either very young men or very new to the field whose paradigm they change. These are the men who, being little committed by prior practice to the traditional rules of normal science, are particularly likely to see that those rules no longer define a playable game and conceive another set that can replace them."

"The transition between competing paradigms cannot be made a step at a time, forced by logic and neutral experience. Like the gestalt switch, it must occur all at once (though not necessarily in an instant) or not at all." Thomas Kuhn

"Contrary to the scientific ideal of getting progressively closer to the truth, it looks rather like cosmology, to borrow a term from technology studies, has become path-dependent: overdetermined by the implications of its past inventions." Bjørn Ekeberg

"There are numerous sociological and historical case studies describing how opinions are established as "knowledge" in societies. For example, Paul Feyerabend explained in 1975 that the establishment of the heliocentric worldview was not based on new discoveries, but on a clever propaganda strategy of Galileo Galilei. According to Feyerabend, the representatives of the geocentric world view "did not recognize the propaganda value of predictions and dramatic shows, nor did they make use of the intellectual and social power of the newly created classes. They lost because they did not take advantage of existing opportunities."" Paul Feyerabend

Quote about the hunt for stellar parallax and the shift from Ptolemaic to Copernican systems by Alan HirshfeldCopyright © yoice.net – Quote Artwork

"In Newton’s day, the Ptolemaic system and the Keplerian version of the Copernican system were taught side by side in the universities of the world. But the pendulum of belief had swung irreversibly to the Copernican side. In the minds of most scientists, the heliocentric universe had become fact…Yet there remained a crucial missing element in what was otherwise a complete and compelling picture of the universe: Not one shred of indisputable observational proof existed that the Earth moved through space.Here then was the holy grail of many an astronomer. To prove that the Earth in fact revolved in a wide orbit around the Sun, the parallax of just one star – any star – had to be detected. The hunt for stellar parallax was on." Alan Hirshfeld
