- At different times in Chinese history, Confucius (trad. 551–479 BCE) has been portrayed as a teacher, advisor, editor, philosopher, reformer, and prophet. The name Confucius, a Latinized combination of the surname Kong 孔 with an honorific suffix “Master” (fuzi 夫子), has also come to be used as a global metonym for different aspects of traditional East Asian society. This association of Confucius with many of the foundational concepts and cultural practices in East Asia, and his casting as a progenitor of “Eastern” thought in Early Modern Europe, make him arguably the most significant thinker in East Asian history.
- Pond (Wikipedia)
A pond is a small, still, land-based body of water formed by pooling inside a depression, either naturally or artificially. A pond is smaller than a lake and there are no official criteria distinguishing the two, although defining a pond to be less than 5 hectares (12 acres) in area, less than 5 metres (16 ft) in depth and with less than 30% of its area covered by emergent vegetation helps in distinguishing the ecology of ponds from those of lakes and wetlands. Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds are usually freshwater but may be brackish in nature. Saltwater pools, with a direct connection to the sea to maintain full salinity, may sometimes be called ‘ponds’ but these are normally regarded as part of the marine environment. They do not support fresh or brackish water-based organisms, and are rather tidal pools or lagoons.
