Thomas Kuhn quote image about scientific progress and new discoveries

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.

But when they add up, they could also suggest a more confounding problem that is not resolved by tweaking parameters or adding new variables." Bjørn Ekeberg

"Science today is locked into paradigms. Every avenue is blocked by beliefs that are wrong, and if you try to get anything published by a journal today, you will run against a paradigm and the editors will turn it down." Sir Fred Hoyle
