A paradigm is a framework or model that shapes how we understand and interpret the world around us. It consists of the beliefs, values, and practices that define a particular discipline or field of study. For example, in science, a paradigm can dictate how researchers approach problems and conduct experiments, influencing what is considered valid knowledge. When a paradigm shifts, it can lead to significant changes in thinking and behavior. This concept is often illustrated by the work of Thomas Kuhn, who described how scientific revolutions occur when existing paradigms are challenged and replaced by new ones. Such shifts can transform entire fields, leading to advancements and new discoveries.
