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.
Taapaca
The term "tara paka" is Aymara for "two-headed eagle" or "winter (prey) bird", and Quechua for Andean eagle. It is also known as Nevados de Putre; sometimes "Nevados de Putre" is used to refer to the volcanic complex and "Taapaca" to its highest summit. The term "taapaca" may also be the origin of the term "tarapaca" and could be an Aymara name for the founder deity Viracocha. "Putre" in turn appears to mean "sound of falling water" in Aymara.
