An epiphany (from the ancient Greek ἐπιφάνεια, epiphaneia, "manifestation, striking appearance") is an experience of sudden and striking realization. Generally the term is
used to describe scientific breakthrough, religious or
philosophical discoveries, but it can apply in any situation in which an enlightening realization allows a problem or situation to be understood from a new and deeper perspective. Epiphanies are studied by
psychologists and other scholars, particularly those attempting to study the process of innovation.
Epiphanies are relatively rare occurrences and generally follow a process of significant thought about a problem. Often they are triggered by a new and key piece of information, but importantly, a depth of prior knowledge is required to allow the leap of
understanding. Famous epiphanies include Archimedes's discovery of a method to determine the density of an object ("Eureka!") and Isaac Newton's realization that a falling apple and the orbiting moon are both pulled by the same force.
