influential theories

Influential theories help us understand how things work in various fields. For example, in psychology, the Pavlovian theory explains how animals learn through associations—like salivating when hearing a bell because they associate it with food. In physics, Einstein’s theory of relativity shows how space and time are connected and how gravity affects them, changing our view of the universe. In economics, the supply and demand theory explains how prices are determined by how much of a product is available and how much people want it. These theories shape our understanding and decisions in everyday life.
