Apophenia (/æpoʊˈfiːniə/) is the tendency to perceive meaningful connections between unrelated things.[1] The term (German: Apophänie from the Greek verb ἀποφαίνειν (apophaínein)) was coined by psychiatrist Klaus Conrad in his 1958 publication on the beginning stages of schizophrenia.[2] He defined it as "unmotivated seeing of connections [accompanied by] a specific feeling of abnormal meaningfulness".[3][4] He described the early stages of delusional thought as self-referential over-interpretations of actual sensory perceptions, as opposed to hallucinations.[1][5]

He even coined a phrase: Verknüpfungszwang - the compulsion to seek connections.

The old saying "a bad penny always turns up" is a colloquial recognition of Gresham's Law.

Bertozzi coined the term bioorthogonal to refer to reactions that occur without interfering with the chemistry of a living cell.
