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.
