What Is Science? 13:58 What is science, anyway? Sir Karl Popper: discussed problem of separating science from nonscience Before Popper, most people thought that most of science is the body of knowledge that is proven correct The essence of science is falsifiability (refutability): scientific theories are capable of being disproven in principle Example: evolution- hasn’t been proven correct; it is remotely possible; hasn’t been disproved yet In contrast, unscientific theories cannot be falsified Popper’s example: Freudian psychoanalysis Largely unfalsifiable – no easy way to disprove it – makes it not a scientific theory Film Clip – Secret of the science What Is Science?
