The story of the word

Archimedes shouting εὕρηκα was using the perfect tense of this verb: I have found it. The word entered English in the early nineteenth century out of German scholarly usage, meaning a method that helps discovery rather than proves a result. Amos Tversky and Daniel Kahneman gave it its current sense in 1974, describing the mental shortcuts people use under uncertainty and the errors they reliably produce.
