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.
Karl Penka
Penka studied anthropology from the point of view of comparative linguistics and took a particular interest in the origins of the Indo-Europeans. He used the term Aryan in the linguistic sense and also extended it into a broad term of race and culture. It was he who popularized the theory that the Aryan race had emerged in Scandinavia and could be identified by the Nordic characteristics of blue eyes and blond hair. In his "Origines Ariacae" ('Origins of the Aryans') of 1883 he proposed that the Indo-European homeland was in the far north, the Hyperborea of antiquity. Penka has been called "a transitional figure between Aryanism and Nordicism".
Penka died in Vienna in 1912. He is now seen as a pioneer of racist and anti-Semitic theories in ethnology.
