Buoyancy
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the Displacement (fluid), displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the objec ...

Xiaolian
Xiaolian (; literally " filial and incorrupt"), was the standard of nominating civil officers started by Emperor Wu of Han in 134 BC. It lasted until its replacement by the imperial examination system during the Sui dynasty. In Confucian philosophy, filial piety is a virtue of respect for one's parents and ancestors. onfucianism in Context Classic Philosophy and Contemporary Issues, East Asia and Beyond/ref> Under the advice of Dong Zhongshu, Emperor Wu ordered each commandery to recommend one filial and one incorrupt candidate for civil offices. Later the nomination became proportional; Emperor He of Han changed the proportion to one candidate for every 200,000 residents, and one for every 100,000 residents in ethnic minority regions. The nominator was also responsible if the nominee was charged with corruption, and could be punished if he refused to nominate qualified individuals. After the Han dynasty, high positions were usually nominated according to the Nine-rank system, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cao Ang
Cao Ang () ( 177 – February or March 197), courtesy name Zixiu, was the eldest son of Cao Cao, a warlord who rose to power towards the end of the Han dynasty and laid the foundation of the state of Cao Wei in the Three Kingdoms period of China.

Nothing was recorded in history about Cao Ang's early life, except that he was nominated as a '' xiaolian'' (civil service candidate) when he reached the age of adulthood (around 19 years old).

Cao Rui
Cao Rui () (204 or 205 – 22 January 239), courtesy name Yuanzhong, was the second emperor of the state of Cao Wei during the Three Kingdoms period. His parentage is in dispute: his mother, Lady Zhen, was Yuan Xi's wife, but she later remarried Cao Pi, the first ruler of Wei. Based on conflicting accounts of his age, Pei Songzhi calculated that, in order to be Cao Pi's son, Cao Rui could not have been 36 (by East Asian age reckoning) when he died as recorded, so the recorded age was in error; late-Qing scholars Lu Bi (卢弼) and Mao Guangsheng (冒广生) argued instead that Cao Rui was Yuan Xi's son. Cao Rui's reign was viewed in many different ways throughout Chinese history. He devoted many resources into building palaces and ancestral temples, and his reign saw the stalemate between his empire, Shu Han, and Eastern Wu become more entrenched. His building projects and his desire to have many concubines (who numbered in the thousands) greatly exhausted the imperial trea ...
