Villages

A village is a clustered person resolution or community, better than a hamlet, but smaller than a town or city. Although usually situated in rural areas, the word urban village may be applied to assured urban neighborhoods. Villages normally are stable with fixed dwellings, but temporary villages can occur. Further, the dwellings of a village are quite close to one another, as against being spread broadly over the landscape.

During the human past, villages have been the normal form of society for agricultural societies, and even for some non-agricultural societies. Towns and cities were few, and were home to only a little proportion of the population. The Industrial Revolution caused a lot of villages to develop into towns and cities; this development of urbanisation has continued and hastened since, even if not always in connection with industrialisation. Villages have thus been eclipsed in value, as units of human culture and settlement.

In Astronomy

Space refers collectively to the relatively empty parts of the universe. Any area outside the atmospheres of any celestial body can be considered 'space'. Although space is certainly spacious, it is not always empty, but can be filled with matter — say a tenuous plasma. In particular, the boundary between space and Earth's atmosphere is conventionally set at the Karman line.

Three Gorges Dam
The Three Gorges Dam spans the Yangtze River on Sandouping, Yichang, Hubei region, China. Construction began in 1994. It will be the major hydroelectric dam in the world, more than five times the size of the Hoover Dam. The reservoir began filling on June 1, 2003, and will occupy the current position of the scenic Three Gorges area, between the cities of Yichang, Hubei; and Fuling, Chongqing. Structural work was finished on May 20, 2006, nine months ahead of schedule. However, some generators still have to be installed and the dam is not expected to become fully equipped until 2009.

Three Gorges Dam, downstream side, 26 July 2004As with many dams, there is controversy over the operating cost and benefits of the Three Gorges Dam. Although there are economic profit from flood control and hydroelectric power, there are also concerns concerning the future of over 1.9 million people who will be displaced by the flood waters, the loss of some valuable archaeological and cultural sites, as well as the effects on the environment. It is believed that the dam was a contributing part in the extinction of the Yangtze River Dolphin.
