A method of making astronomical observation instruments at the time of Qing Dynasty.
The history of science and technology in China is both long and rich with many contributions to science and technology. In antiquity, independently of Greek philosophers and other civilizations, ancient Chinese philosophers made significant advances in science, technology, mathematics, and astronomy. The first recorded observations of comets, solar eclipses, and supernovae were made in China.Ancient Chinese Astronomy Traditional Chinese medicine, acupuncture and herbal medicine were also practised.
Among the earliest inventions were the abacus, the "shadow clock," and the first flying machines such as kites and Kongming lanternsInventions (Pocket Guides). The four Great Inventions of ancient China: the compass, gunpowder, papermaking, and printing, were among the most important technological advances, only known in Europe by the end of the Middle Ages. The Tang dynasty (AD 618 - 906) in particular, was a time of great innovation. A good deal of exchange occurred between Western and Chinese discoveries up to the Qing Dynasty.
The Jesuit China missions of the 16th and 17th centuries introduced Western science and astronomy, then undergoing its own revolution, to China, and knowledge of Chinese technology was brought to Europe.Agustín Udías, p.53 Much of the early Western work in the history of science in China was done by Joseph Needham.

Remains of a Chinese crossbow, 2nd century BC.
One of the oldest longstanding contributions of the ancient Chinese are in Traditional Chinese medicine, including acupuncture and herbal medicine, derived from Taoist philosophy. The practice of acupuncture can be traced as far back as the 1st millennium BC and some scientists believe that there is evidence that practices similar to acupuncture were used in Eurasia during the early Bronze Age.[1], [2]
The ancient Chinese also invented counting and time-keeping devices, which facilitated mathematical and astronomical observations. Shadow clocks, the forerunners of the sundial, first appeared in China about 4,000 years ago,Inventions (Pocket Guides). while the abacus was invented in China sometime between 1000 BC and 500 BC.Video: Computers: The Abacus. Encyclopædia Britannica.The Invention of the Abacus. Maxfield & Montrose Interactive Inc. Using these the Chinese were able to record observations, documenting the first solar eclipse in 2137 BC, and making the first recording of any planetary grouping in 500 BC. The Book of Silk was the first definitive atlas of comets, written c. 400 BC. It listed 29 comets (referred to as broom stars) that appeared over a period of about 300 years, with renderings of comets describing an event its appearance corresponded to.
Replica of Zhang Heng\'s seismometer Houfeng Didong Yi
In architecture, the pinnacle of Chinese technology manifested itself in the Great Wall of China, under the first Chinese Emperor Qin Shi Huang between 220 BC and 200 BC. Typical Chinese architecture changed little from the succeeding Han Dynasty until the 19th century.Buildings (Pocket Guides). The Qin Dynasty also developed the crossbow, which later became the mainstream weapon in Europe. Several remains of crossbows have been found among the soldiers of the Terracotta Army in the tomb of Qin Shi Huang.Weapons of the terracotta army
The Eastern Han Dynasty scholar and astronomer Zhang Heng (78-139 AD) invented the first water-powered rotating armillary sphere (the first armillary sphere having been invented by the Greek Eratosthenes), and catalogued 2500 stars and over 100 constellations. In 132, he invented the first seismological detector, called the "Houfeng Didong Yi" ("Instrument for inquiring into the wind and the shaking of the earth").People\'s Daily Online According to the History of Later Han Dynasty (25-220 AD), this seismograph was an urn-like instrument, which would drop one of eight balls to indicate when and in which direction an earthquake had occurred. On June 13, 2005, Chinese seismologists announced that they had created a replica of the instrument.
The mechanical engineer Ma Jun (c. 200-265 AD) was another impressive figure from ancient China. Ma Jun improved the design of the silk loom,Needham, Volume 4, Part 2, 39. designed mechanical chain pumps to irrigate palatial gardens, and created a large and intricate mechanical puppet theatre for Emperor Ming of Wei, which was operated by a large hidden waterwheel.Needham, Volume 4, Part 2, 158. However, Ma Jun\'s most impressive invention was the South Pointing Chariot, a complex mechanical device that acted as a mechanical compass vehicle. It incorporated the use of a differential gear in order to apply equal amount of torque to wheels rotating at different speeds, a device that is found in all modern automobiles.Needham, Volume 4, Part 2, 40.
Sliding calipers were invented in China almost 2,000 years ago. The Chinese civilization was the first civilization to succeed in exploring with aviation, with the kite and Kongming lantern (proto Hot air balloon) being the first flying machines.
The "Four Great Inventions of ancient China" (traditional Chinese: 四大發明; simplified Chinese: 四大发明; pinyin: sì dà fāmíng) are the compass, gunpowder, papermaking, and printing. Paper and printing were developed first. Printing was recorded in China in the Tang Dynasty, although the earliest surviving examples of printed cloth patterns date to before 220.Shelagh Vainker Pin-pointing the development of the compass can be difficult: the magnetic attraction of a needle is attested by the Louen-heng, composed between AD 20 and 100,"A lodestone attracts a needle." Li Shu-hua, p.176 although the first undisputed magnetized needles in Chinese literature appear in 1086.Li Shu-hua, p.182f.
By AD 300, Ge Hong, an alchemist of the Jin Dynasty, conclusively recorded the chemical reactions caused when saltpetre, pine resin and charcoal were heated together in his book "Book of the Master of the Preservations of Solidarity".Liang, pp. Appendix C VII Another early record of gunpowder, a Chinese book from c. 850 AD indicates that gunpowder was a byproduct of Taoist alchemical efforts to develop an elixir of immortality:Kelly, p. 3
"Some have heated together sulfur, realgar and saltpeter with honey; smoke and flames result, so that their hands and faces have been burnt, and even the whole house where they were working burned down."Kelly, p. 4

These four discoveries had an enormous impact on the development of Chinese civilization and a far-ranging global impact. Gunpowder, for example, spread to the Arabs in the 13th century and thence to Europe.Kelly, p. 22. "Around 1240 the Arabs acquired knowledge of saltpeter (“Chinese snow”) from the East, perhaps through India. They knew of gunpowder soon afterward. They also learned about fireworks (“Chinese flowers”) and rockets (“Chinese arrows”)." According to English philosopher Francis Bacon, writing in Novum Organum:
"Printing, gunpowder and the compass: These three have changed the whole face and state of things throughout the world; the first in literature, the second in warfare, the third in navigation; whence have followed innumerable changes, in so much that no empire, no sect, no star seems to have exerted greater power and influence in human affairs than these mechanical discoveries." Novum Organum, Liber I, CXXIX - Adapted from the 1863 translation
One of the most important military treatises of all Chinese history was the Huo Long Jing written by Jiao Yu in the 14th century. For gunpowder weapons, it outlined the use of fire arrows and rockets, fire lances and firearms, land mines and naval mines, bombards and cannons, along with different compositions of gunpowder, including \'magic gunpowder\', \'poisonous gunpowder\', and \'blinding and burning gunpowder\' (refer to his article).
For the 11th century invention of ceramic movable type printing by Bi Sheng (990-1051), it was enhanced by the wooden movable type of Wang Zhen in 1298 and the bronze metal movable type of Hua Sui in 1490.
Ships of the world in 1460 (Fra Mauro map). Chinese junks are described as very large, three or four-masted ships.
Among the scientific accomplishments of early China were matches, dry docks, the double-action piston pump, cast iron, the iron plough, the horse collar, the multi-tube seed drill, the wheelbarrow, the suspension bridge, the parachute, natural gas as fuel, the raised-relief map, the propeller, the sluice gate, and the pound lock. The Tang Dynasty (618 - 906 AD) in particular was a time of great innovation.
In the 7th century, book-printing was developed in China and Japan, using delicate hand-carved wooden blocks to print individual pages. The 9th century Diamond Sutra is the earliest known printed document. Movable type was also used in China for a time, but was abandoned because of the number of characters needed; it would not be until Gutenburg that the technique was reinvented in a suitable environment.
Paper money was first introduced in the Song Dynasty, and came into widespread use under Mongol rule.
In addition to gunpowder, the Chinese also developed improved delivery systems for the Byzantine weapon of Greek fire, Meng Huo You and Pen Huo Qi first used in China c. 900.Turnbull, p. 43 Chinese illustrations were more realistic than in Byzantine manuscripts, and detailed accounts from 1044 recommending its use on city walls and ramparts show the brass container as fitted with a horizontal pump, and a nozzle of small diameter. The records of a battle on the Yangtze near Nanjing in 975 offer an insight into the dangers of the weapon, as a change of wind direction blew the fire back onto the Song forces.
The Song Dynasty (960-1279) brought a new stability for China after a century of civil war, and started a new area of modernisation by encouraging examinations and meritocracy. The first Song Emperor created political institutions that allowed a great deal of freedom of discourse and thought, which facilitated the growth of scientific advance, economic reforms, and achievements in arts and literature.Money of the World Special Christmas Edition, Orbis Publishing Ltd, 1998. Trade flourished both within China and overseas, and the encouragement of technology allowed the mints at Kaifeng and Hangzhou to gradually increase in production. In 1080, the mints of Emperor Shenzong were produced 5 billion coins (roughly 50 per Chinese citizen), and the first banknotes were produced in 1023. These coins were so durable that they would still be in use 700 years later, in the 18th century.

There were many famous inventors and early scientists in the Song Dynasty period. The statesman Shen Kuo is best known for his book known as the Dream Pool Essays (1088 AD). In it, he wrote of use for a drydock to repair boats, the navigational magnetic compass, and the discovery of the concept of true north (with magnetic declination towards the North Pole). Shen Kuo also devised a geological theory for land formation, or geomorphology, and theorized that there was climate change in geological regions over an enormous span of time.
The equally talented statesman Su Song was best known for his engineering project of the Astronomical Clock Tower of Kaifeng, by 1088 AD. The clock tower was driven by a rotating waterwheel and escapement mechanism, the latter of which did not appear in clockworks of Europe until two centuries later. Crowning the top of the clock tower was the large bronze, mechanically-driven, rotating armillary sphere. In 1070, Su Song also compiled the Ben Cao Tu Jing (Illustrated Pharmacopoeia, original source material from 1058 – 1061 AD) with a team of scholars. This pharmaceutical treatise covered a wide range of other related subjects, including botany, zoology, mineralogy, and metallurgy.
Chinese astronomers were also among the first to record observations of a supernova, in 1054, making the Crab Nebula the first astronomical object recognized as being connected to a supernova explosion.Mayall N.U. (1939), The Crab Nebula, a Probable Supernova, Astronomical Society of the Pacific Leaflets, v. 3, p.145 Arabic and Chinese astronomy intermingled under the Mongol rule of the Yuan Dynasty. Muslim astronomers worked in the Chinese astronomical bureau established by Kublai Khan, while some Chinese astronomers also worked at the Persian Maragha observatory.Abstracta Iranica (Before this, in ancient times, Indian astronomers had lent their expertise to the Chinese court.[3])
Mongol rule also saw technological advances from an economic perspective, with the first mass production of paper banknotes by Kublai Khan in the 13th century. Numerous contacts between Europe and the Mongols occurred in the 13th century, particularly through the unstable Franco-Mongol alliance. Chinese corps, expert in siege warfare, formed an integral part of the Mongol armies campaigning in the West. In 1259-1260 military alliance of the Franks knights of the ruler of Antioch Bohemond VI and his father-in-law Hetoum I with the Mongols under Hulagu, in which they fought together for the conquests of Muslim Syria, taking together the city of Aleppo, and later Damascus."Histoire des Croisades", René Grousset, p581, ISBN 226202569X William of Rubruck, an ambassador to the Mongols in 1254-1255, a personal friend of Roger Bacon, is also often designated as a possible intermediary in the transmission of gunpowder know-how between the East and the West."The Eastern Origins of Western Civilization", John M.Hobson, p186, ISBN 0521547245 The compass is often said to have been introduced by the Master of the Knights Templar Pierre de Montaigu between 1219 to 1223, from one of his travels to visit the Mongols in Persia.Source
Jesuits in China.
The Jesuit China missions of the 16th and 17th centuries introduced Western science and astronomy, then undergoing its own revolution, to China. The Society of Jesus introduced, according to Thomas Woods, "a substantial body of scientific knowledge and a vast array of mental tools for understanding the physical universe, including the Euclidean geometry that made planetary motion comprehensible." Another expert quoted by Woods said the scientific revolution brought by the Jesuits coincided with a time when science was at a very low level in China:

Conversely, the Jesuits were very active in transmitting Chinese knowledge to Europe. Confucius\'s works were translated into European languages through the agency of Jesuit scholars stationned in China. Matteo Ricci started to report on the thoughts of Confucius, and Father Prospero Intorcetta published the life and works of Confucius into Latin in 1687."Windows into China", John Parker, p.25 It is thought that such works had considerable importance on European thinkers of the period, particularly among the Deists and other philosophical groups of the Enlightenment who were interested by the integration of the system of morality of Confucius into Christianity."Windows into China", John Parker, p.25, ISBN 0890730504"The Eastern origins of Western civilization", John Hobson, p194-195, ISBN 0521547245

One question that has been the subject of debate among historians has been why China did not develop a scientific revolution and why Chinese technology fell behind that of Europe. Many hypotheses have been proposed ranging from the cultural to the political and economic. Nathan Sivin has argued that China indeed had a scientific revolution in the 17th century and that we are still far from understanding the scientific revolutions of the West and China in all their political, economic and social ramifications.Nathan Sivin\'s Curriculum Vitae John K. Fairbank argued that the Chinese political system was hostile to scientific progress.
Needham argued, and most scholars agreed, that cultural factors prevented these Chinese achievements from developing into what could be called "science".Woods It was the religious and philosophical framework of the Chinese intellectuals which made them unable to believe in the ideas of laws of nature:

Similar grounds have been found for questioning much of the philosophy behind traditional Chinese medicine, which, derived mainly from Taoist philosophy, reflects the classical Chinese belief that individual human experiences express causative principles effective in the environment at all scales. Because its theory predates use of the scientific method, it has received various criticisms based on scientific thinking. Even though there are physically verifiable anatomical or histological bases for the existence of acupuncture points or meridians, for instance skin conductance measurements show increases at the predicted points (see _The Body Electric_ by Robert O. Becker, M.D., pgs 233-236), philosopher Robert Todd Carroll, a member of the Skeptics Society, deemed acupuncture a pseudoscience because it "confuse(s) metaphysical claims with empirical claims".[4]:
More recent historians have questioned political and cultural explanations and have focused more on economic causes. Mark Elvin\'s high level equilibrium trap is one well-known example of this line of thought, as well as Kenneth Pomeranz\' argument that resources from the New World made the crucial difference between European and Chinese development. Other events such as Haijin and Cultural Revolution have isolated China during critical times.
After the establishment of the People\'s Republic in 1949, China reorganized its science establishment along Soviet lines. Since 1975, science and technology was one of the Four Modernizations, and its high-speed development was declared essential to all national economic development by Deng Xiaoping. Major breakthroughs occurred in the 1980s in nuclear weapons, satellite launching and recovery, superconductivity, high-yield hybrid rice. Policy formulation at top levels had put emphasis on the application of science to industry and foreign technology transfer.
Since the 21st century, science and technology in the People\'s Republic of China has been growing rapidly. As the People\'s Republic of China becomes better connected to the global economy, the government has placed more emphasis on science and technology. This has led to increases in funding, improved scientific structure, and more money for research. These factors have led to advancements in agriculture, medicine, genetics, and global change.
