Sir Karl Popper

Sir Karl Popper was a philosopher best known for his ideas on scientific progress and critical thinking. He believed that scientific theories can never be proven true, only tested and potentially falsified. A good scientific theory should make predictions that can be tested and potentially shown to be wrong, which helps advance knowledge. Popper also emphasized the importance of open debate and critical discussion to improve ideas and prevent dogma. His approach encourages skepticism and continuous testing to distinguish scientific claims from false or untestable beliefs.
