Thomas Kuhn
Thomas Kuhn was an influential philosopher of science who revolutionized our understanding of scientific progress through his concept of "paradigm shifts." In his groundbreaking 1962 work "The Structure of Scientific Revolutions," Kuhn challenged the prevailing view that science advances through steady, cumulative growth, instead arguing that it proceeds through periods of "normal science" punctuated by revolutionary transformations when established frameworks become inadequate. S​cientific knowledge is not simply an objective mirror of reality but is influenced by historical and sociological factors.    C
"The answers you get depend on the questions you ask."

Thomas Samuel Kuhn was an influential American historian and philosopher of science born on July 18, 1922, in Cincinnati, Ohio. He died on June 17, 1996, in Cambridge, Massachusetts at the age of 73. Kuhn was born into a Jewish family, though they were non-observant.
Kuhn is best known for his groundbreaking work "The Structure of Scientific Revolutions," published in 1962. This book introduced the concept of "paradigm shifts" and revolutionized the way people think about scientific progress. He argued that scientific advancement occurs not through a linear accumulation of knowledge, but through periodic revolutionary changes in the fundamental assumptions and methods used by scientists.
In addition to "The Structure of Scientific Revolutions," Kuhn authored several other important works, including:

1. "The Copernican Revolution" (1957)
2. "The Essential Tension" (1977)
3. "Black-Body Theory and the Quantum Discontinuity, 1894-1912" (1978)
4. "The Road since Structure: Philosophical Essays, 1970-1993, with an Autobiographical Interview" (2000, posthumously)

Kuhn's ideas have had a profound impact on various fields beyond science, including sociology, economics, and political science. His work challenged the traditional view of scientific progress and emphasized the role of social and historical factors in shaping scientific knowledge.
Here are ten notable quotations from Thomas Kuhn:

1. "Normal science, the activity in which most scientists inevitably spend almost all their time, is predicated on the assumption that the scientific community knows what the world is like."
2. "The answers you get depend on the questions you ask."
3. "To reject one paradigm without simultaneously substituting another is to reject science itself."
4. "Truth emerges more readily from error than from confusion."
5. "Under normal conditions the research scientist is not an innovator but a solver of puzzles, and the puzzles upon which he concentrates are just those which he believes can be both stated and solved within the existing scientific tradition."
6. "The man who is striving to solve a problem defined by existing knowledge and technique is not, however, just looking around. He knows what he wants to achieve, and he designs his instruments and directs his thoughts accordingly."
7. "Paradigms are not corrigible by normal science at all. Instead, as we have already seen, normal science ultimately leads only to the recognition of anomalies and to crises."
8. "Almost always the men who achieve these fundamental inventions of a new paradigm have been either very young or very new to the field whose paradigm they change."
9. "The competition between paradigms is not the sort of battle that can be resolved by proofs."
10. "Though the world does not change with a change of paradigm, the scientist afterward works in a different world."

Kuhn's career included teaching positions at Harvard University, the University of California, Berkeley, Princeton University, and the Massachusetts Institute of Technology (MIT). His work continues to be widely influential in discussions about the nature of scientific progress and the philosophy of science.
