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.
Wanaka
European settlement began in the Upper Clutha River Valley in the 1850s, with the establishment of sheep stations by runholders. The first station was at Albert Town, the only place where settlers could ford the Clutha River. The present site of Wanaka was first surveyed in 1863, and settlement increased in Pembroke (the old name for Wanaka) during the 1870s because of timber milling in the Matukituki Valley and the use of Lake Wanaka for transport.
