Thomas Kuhn

Thomas Kuhn was an American philosopher and historian of science, born in Cincinnati in 1922 and died in Cambridge, Massachusetts in 1996. Trained originally as a physicist, he argued in his 1962 book The Structure of Scientific Revolutions that science does not progress by smoothly accumulating facts but alternates between long stretches of normal science working within a shared paradigm and rare, disruptive paradigm shifts when that shared framework breaks down and is replaced, a picture that put the words paradigm and paradigm shift into everyday use well beyond science itself. Carried under scientist alongside Popper on the same reasoning this file's header gives.
