Karl R. Popper

Karl R. Popper was a renowned philosopher of science who believed that for a theory to be scientific, it must be testable and falsifiable—meaning it can be proven wrong through experiments or observations. He emphasized that science advances by proposing bold hypotheses that are rigorously tested, and those that survive remain as provisional truths. Popper also argued against certainty in scientific knowledge, advocating for a culture of critical thinking and continuous questioning. His ideas influence how we understand scientific progress, emphasizing the importance of openness to refutation and the idea that no theory can ever be proven absolutely true.
