Question: The country, from where a philosopher first described evaporation, had many contacts with another administration of the Yuan dynasty. What is the Brahmaputra River called in the area of that administration and Bangladesh?

Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. 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. 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. His main work was the "Lunheng" (論衡, "Critical Essays"). Wang also accurately described the process of the water cycle. <SEP> the columbia encyclopedia distinguishes between the yuan dynasty and the other mongol empire khanates of ilkhanate, chagatai khanate and the golden horde. it describes the yuan dynasty as "a mongol dynasty of china that ruled from 1271 to 1368, and a division of the great empire conquered by the mongols. founded by kublai khan, who adopted the chinese dynastic name of yüan in 1271." the encyclopedia americana describes the yuan dynasty as "the line of mongol rulers in china" and adds that the mongols "proclaimed a chinese-style yüan dynasty at khanbaliq (beijing)." the metropolitan museum of art writes that the mongol rulers of the yuan dynasty "adopted chinese political and cultural models; ruling from their capitals in dadu, they assumed the role of chinese emperors," although tibetologist thomas laird dismissed the yuan dynasty as a non-chinese polity and plays down its chinese characteristics. the metropolitan museum of art also noted that in spite of the gradual assimilation of yuan monarchs, the mongol rulers largely ignored the literati and imposed harsh policies discriminating against southern chinese. in his kublai khan: his life and times, rossabi explains that kublai "created government institutions that either resembled or were the same as the traditional chinese ones", and he "wished to signal to the chinese that he intended to adopt the trappings and style of a chinese ruler". <SEP> Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds. 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. <SEP> Other historians also assert that these Ming titles were nominal and did not actually confer the authority that the earlier Yuan titles had. Van Praag writes that the "numerous economically motivated Tibetan missions to the Ming Court are referred to as 'tributary missions' in the Ming Shih." Van Praag writes that these "tributary missions" were simply prompted by China's need for horses from Tibet, since a viable horse market in Mongol lands was closed as a result of incessant conflict. Morris Rossabi also writes that "Tibet, which had extensive contacts with China during the Yuan, scarcely had diplomatic relations with the Ming." The late Turrell V. Wylie, a former professor of the University of Washington, and Li Tieh-tseng argue that the reliability of the heavily censored History of Ming as a credible source on Sino-Tibetan relations is questionable, in the light of modern scholarship. <SEP> the ganges - brahmaputra delta (also known as the brahmaputra delta, the sunderbans delta or the bengal delta) is a river delta in the bengal region of the south asia, consisting of bangladesh and the indian state of west bengal. it is the world's largest delta and empties into the bay of bengal. it is also one of the most fertile regions in the world, thus earning the nickname the green delta. the delta stretches from the hooghly river on the west to the meghna river on the east. it is approximately 354 km (220 mi) across at the bay of bengal. kolkata in india and mongla in bangladesh are the principal seaports of the delta. <SEP> It is also called Tsangpo - Brahmaputra (when referring to the whole river including the stretch within Tibet). The Brahmaputra (/ ˌbrɑːməˈpuːtrə / is one of the major rivers of Asia, a trans - boundary river which flows through China, India and Bangladesh. As such, it is known by various names in the region: Assamese: ব্ৰহ্মপুত্ৰ নদ ('নদ' nôd, masculine form of 'নদী' nôdi ``river '') Brôhmôputrô (bɹɔɦmɔputɹɔ); Sanskrit: ब्रह्मपुत्र, IAST: Brahmaputra; Tibetan: ཡར ་ ཀླུངས ་ གཙང ་ པོ ་, Wylie: yar klung gtsang po Yarlung Tsangpo; simplified Chinese: 布拉马普特拉河; traditional Chinese: 布拉馬普特拉河; pinyin: Bùlāmǎpǔtèlā Hé. The Manas River, which runs through Bhutan, joins it at Jogighopa, in India. It is the ninth largest river in the world by discharge, and the 15th longest.
