Popper, Karl

Karl Popper was a philosopher of science known for his work on scientific methodology. He argued that for a theory to be considered scientific, it must be testable and falsifiable—meaning it can be proven wrong through evidence. Popper emphasized that science advances by making bold hypotheses and then trying to disprove them, rather than verifying theories repeatedly. His ideas helped distinguish scientific knowledge from metaphysics or pseudoscience, encouraging open inquiry and critical thinking. Overall, Popper's work has influenced how we evaluate the reliability of scientific claims and the progress of scientific understanding.
