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.
Eurafrica
The term was already coined in the high imperial period of the nineteenth century. It played a role in some technocratical fantasies, e.g. the Atlantropa vision in the 1920s and 30s (compare the recently failed Desertec project). It then aimed to integrate African colonies providing raw materials with Europe. Erich Obst was one of the propagators during World War II.
