Question: Who created the civil service system in the country the person who described the process of evaporation is from?

Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds. <SEP> the first celluloid as a bulk material for forming objects was made in 1855 in birmingham, england, by alexander parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale - up costs. parkes patented his discovery after realising a solid residue remained after evaporation of the solvent from photographic collodion. <SEP> a system akin to the bessemer process has existed since the 11th century in east asia. economic historian robert hartwell writes that the chinese of the song dynasty innovated a ``partial decarbonization ''method of repeated forging of cast iron under a cold blast. sinologist joseph needham and historian of metallurgy theodore a. wertime have described the method as a predecessor to the bessemer process of making steel. this process was first described by the prolific scholar and polymath government official shen kuo (1031 -- 1095) in 1075, when he visited cizhou. hartwell states that perhaps the earliest center where this was practiced was the great iron - production district along the henan -- hebei border during the 11th century. <SEP> Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. He developed a rational, secular, naturalistic and mechanistic account of the world and of human beings and gave a materialistic explanation of the origin of the universe. This book contained many theories involving early sciences of astronomy and meteorology, and Wang Chong was even the first in Chinese history to mention the use of the square-pallet chain pump, which became common in irrigation and public works in China thereafter. His main work was the "Lunheng" (論衡, "Critical Essays"). Wang also accurately described the process of the water cycle. <SEP> However, the structure of the examination system was extensively expanded during the reign of Wu Zetian: the impact of Wu's use of the testing system is still a matter for scholarly debate. During the Song dynasty the emperors expanded both examinations and the government school system, in part to counter the influence of military aristocrats, increasing the number of those who passed the exams to more than four to five times that of the Tang. Thus the system played a key role in the selection of the scholar - officials, who formed the elite members of society. During the Ming and Qing dynasties, the system contributed to the narrowness of intellectual life and the autocratic power of the emperor. The system continued with some modifications until its 1905 abolition under the Qing dynasty. Other brief interruptions to the system occurred, such as at the beginning of the Yuan dynasty in the 13th century. The modern examination system for selecting civil servants also indirectly evolved from the imperial one. Although, in a general way, the formative ideas behind the imperial exams can be traced back at least to Zhou dynasty times (or, more mythologically, Yao), such as imperial promotion for displaying skill in archery contests, the imperial examination system in its classical manifestation is historically attested to have been established in 605, during the Sui dynasty; which in the quickly succeeding Tang dynasty was used only on a relatively small scale, especially in its early phase.
