The Structure of Scientific Revolutions

Thomas S. Kuhn

Thomas S. Kuhn’s seminal work upends the traditional view of science as a linear, cumulative pursuit of truth. Introducing the core concept of the 'paradigm'—a shared framework of theories, methods, and assumptions guiding scientific communities—Kuhn distinguishes between 'normal science,' where researchers solve puzzles within an established paradigm, and 'scientific revolutions,' triggered when persistent anomalies expose fatal flaws in the existing framework, sparking a crisis. When a new, incompatible paradigm emerges, it replaces the old one in a non-cumulative shift; Kuhn argues these paradigms are 'incommensurable,' meaning they can’t be directly compared due to differing standards and worldviews. He also explores how textbooks rewrite history to mask revolutionary shifts, framing science as steady progress rather than a series of paradigm overhauls. This work redefined the philosophy of science, forcing scholars to rethink how knowledge evolves in scientific fields.

Heat Is Particle Motion

Core claim: Heat is not a special fluid, but random motion of tiny matter particles. Continuous friction can generate unlimited heat, which can never be explained by the "caloric" matter hypothesis.

Newton Started Mechanical Thinking

Newton’s classical mechanics brought the mechanical thinking revolution, which regarded the universe as a precision clock running by fixed rules, broke medieval theological superstition and guided later industrial inventions.

Scientific Revolution

16-17th century shift from old ideas (geocentrism) to modern science. Key figures: Copernicus (heliocentrism), Galileo, Newton (gravity).

Scientific Revolution Shift

The scientific revolution dethroned Earth as the universe’s center. Newton’s gravity showed natural laws could be explained with math, weakening church authority.
