Eureka (word)
"Eureka" comes from the Ancient Greek word "heúrēka", meaning "I found (it)", which is the first person singular perfect indicative active of the verb "heuriskō" "I find". It is closely related to heuristic, which refers to experience-based techniques for problem solving, learning, and discovery.
Évora
The etymological origin of the name "Ebora" is from the ancient Celtic word "ebora/ebura", plural genitive of the word "eburos" (yew), name of a species of tree, so its name means "of the yew trees." The city of York, in northern England, at the time of the Roman Empire, was called "Eboracum/Eburacum", named after the ancient Celtic place name *"Eborakon" (Place of Yew Trees), so the old name of York is etymologically related to the city of Évora. Alternative hypotheses are that the name is derived from "oro", "aurum", (gold) as the Romans had extensive gold mining in Portugal; or it may named after ivory workers, but these two hypotheses are much less likely than the first one, because the name Évora has no relation with gold or with ivory in ancient Celtic, Latin or Portuguese languages or other languages, there is no etymological ground for these two hypotheses.
It may have been capital of the kingdom of Astolpas.
