Eureka (word)
The exclamation 'Eureka!' is attributed to the ancient Greek scholar Archimedes. He reportedly proclaimed "Eureka! Eureka!" after he had stepped into a bath and noticed that the water level rose, whereupon he suddenly understood that the volume of water displaced must be equal to the volume of the part of his body he had submerged. (This relation is "not" what is known as Archimedes' principle—that deals with the "upthrust" experienced by a body immersed in a fluid.) He then realized that the volume of irregular objects could be measured with precision, a previously intractable problem. He is said to have been so eager to share his discovery that he leapt out of his bathtub and ran naked through the streets of Syracuse.
Yugra
Yugra is also considered to be the place of origin of the Hungarians (in Hungarian "magyar őshaza"). It is thought that the name "Hungary" is a variety of the name Yugra (The Hungarians also were known in several languages under the name of "Ugri", and are still known under this name in Ukrainian). "Hungary" is also said to derive from On-Ogur, meaning "Ten Ugors" or "Hun Ugors". The word Ugor itself may be of Turkic origin meaning "tribe". The Hungarian language is also the closest linguistic relative of Khanty and Mansi. It is considered that Hungarians moved from Yugra to the west, first settling on the western side of the Urals, in the region known as "Magna Hungaria" (Great Yugria). Then they moved further to the west, to the region of "Levédia" (present-day east Ukraine), then to the region of "Etelköz" (present-day west Ukraine), finally reaching the Carpathian Basin in the 9th century.
