Shout accompanying a brilliant realization

I believe the answer is:

eureka

(Other definitions for eureka that I've seen before include "Archimedes' shout of triumph - re a uke (anag)" , "Archimedes's call of triumph" , "Cry announcing a brilliant discovery" , "Exclamation of triumph" , "Cry on a great discovery" .)

I've seen this clue in The New York Times.
