. Needham notes that the invention of the crossbow "far outstripped the progress in defensive armor", which made the wearing of armor useless to the princes and dukes of the states., p. 10. At this time, there were also many nascent schools of thought in China—the Hundred Schools of Thought (諸子百家), scattered among many polities. The schools served as communities which advised the rulers of these states. Mo Di (墨翟 Mozi, 470 BCE–c. 391 BCE) introduced concepts useful to one of those rulers, such as defensive fortification. One of these concepts, ''fa'' (法 principle or method) was extended by the School of Names (名家 ''Ming jia'', ''ming''=name), which began a systematic exploration of logic. The development of a school of logic was cut short by the defeat of Mohism's political sponsors by the

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").

and archaeology. In accordance with the beliefs of the later Leopold von Ranke (1795–1886), some Song gentry—such as Zhao Mingcheng (1081–1129)—supported the primacy of contemporaneous archaeological finds of ancient inscriptions over historical works written after the fact, which they contested to be unreliable in regard to the former evidence.Rudolph, R.C. "Preliminary Notes on Sung Archaeology," ''The Journal of Asian Studies'' (Volume 22, Number 2, 1963): 169–177.

Chemistry

Until the Song dynasty, Chinese medicine classified drugs under the system of the ''Zhenghe bencao'' (Herbal of the Zhenghe Era): #Superior drugs, associated with immortality, were used for the realization of vital powers #Medium drugs that enrich one's nature #Inferior drugs were those used to treat diseases These early forms of drugs were made using primitive methods, usually just simple dried herbs, or unprocessed minerals. They were developed into combinations known as "elixirs of immortality". These early magical practices, supported by the imperial courts of

This drawback to Chinese science was lamented even by the mathematician Yang Hui (1238–1298), who criticized earlier mathematicians such as Li Chunfeng (602–670) who were content with using methods without working out their theoretical origins or principle, stating: Despite this, Chinese thinkers of the Middle Ages proposed some hypotheses which are in accordance with modern principles of science.

Shen believed that rays of sunlight refracted before reaching the surface of the Earth, hence the appearance of the observed Sun from Earth did not match its exact location. Coinciding with the astronomical work of his colleague Wei Pu, Shen and Wei realized that the old calculation technique for the mean Sun was inaccurate compared to the apparent Sun, since the latter was ahead of it in the accelerated phase of motion, and behind it in the retarded phase. Shen supported and expanded upon beliefs earlier proposed by

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: Johann Adam Schall published Yuan Jing Shuo, Explanation of the Telescope, in 1626, in Latin and Chinese. Schall's book referred to the telescopic observations of Galileo. Conversely, the Jesuits were very active in transmitting Chinese knowledge to Europe.

Scientific and technological stagnation

One question that has been the subject of debate among historians has been why China did not develop a
scientific revolution The Scientific Revolution was a series of events that marked the emergence of History of science, modern science during the early modern period, when developments in History of mathematics#Mathematics during the Scientific Revolution, mathemati ...
and why Chinese technology fell behind that of Europe. Many hypotheses have been proposed ranging from the cultural to the political and economic. John K. Fairbank, for example, argued that the Chinese political system was hostile to scientific progress. As for Needham, he wrote that cultural factors prevented traditional Chinese achievements from developing into what could be called "science." It was the religious and philosophical framework of the Chinese intellectuals which made them unable to believe in the ideas of laws of nature: Another prominent historian of science, Nathan Sivin, has argued that China did indeed experience a scientific revolution in the 17th century; however, it must be understood in the context of its time and culture, rather than through a Western lens as an analog of Europe's revolution. There are also questions about the philosophy behind traditional Chinese medicine, which, derived partly 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 The scientific method is an Empirical evidence, empirical method for acquiring knowledge that has been referred to while doing science since at least the 17th century. Historically, it was developed through the centuries from the ancient and ...

because it "confuse(s) metaphysical claims with empirical claims". More recent historians have questioned political and cultural explanations and have put greater focus on economic causes. Mark Elvin's high level equilibrium trap is one well-known example of this line of thought. It argues that the Chinese population was large enough, workers cheap enough, and agrarian productivity high enough to not require mechanization: thousands of Chinese workers were perfectly able to quickly perform any needed task. Other events such as Haijin, the Opium Wars and the resulting hate of European influence prevented China from undergoing an Industrial Revolution; copying Europe's progress on a large scale would be impossible for a lengthy period of time. Political instability under Cixi rule (opposition and frequent oscillation between modernists and conservatives), the Republican wars (1911–1933), the Sino-Japanese War (1933–1945), the Communist/Nationalist War (1945–1949) as well as the later

postulates that the lack of geographic barriers within much of Chinaessentially a wide plain with two large navigable rivers and a relatively smooth coastlineled to a single government without competition. At the whim of a ruler who disliked new inventions, technology could be stifled for half a century or more. In contrast, Europe's barriers of the Pyrenees, the Alps, and the various defensible peninsulas (Denmark, Scandinavia, Italy, Greece, etc.) and islands (Britain, Ireland, Sicily, etc.) led to smaller countries in constant competition with each other. If a ruler chose to ignore a scientific advancement (especially a military or economic one), his more-advanced neighbors would soon usurp his throne. This explanation, however, ignores the fact that China had been politically fragmented in the past, and was thus not inherently disposed to political unification.


The Republic of China (1912–1949)

The
Republic of China (1912–1949) The Republic of China (ROC) began on 1 January 1912 as a sovereign state in mainland China following the 1911 Revolution, which overthrew the Manchu people, Manchu-led Qing dynasty and ended China's imperial China, imperial history. From 1927, ...
saw the introduction in earnest of modern science to China. Large numbers of Chinese students studied abroad in Japan and in Europe and the US. Many returned to help teach and to found numerous schools and universities. Among them were numerous outstanding figures, including Cai Yuanpei, Hu Shih, Weng Wenhao, Ding Wenjiang, Fu Ssu-nien, and many others. As a result, there was a tremendous growth of modern science in China. As the Communist Party took over China's mainland in 1949, some of these Chinese scientists and institutions moved to Taiwan. The central science academy,

, also moved there. Participants in the May Fourth Movement of 1919 advocated that science (nicknamed, "Mr. Science"), along with Democracy ("Mr. Democracy") could save China. Belief in the idea of "saving China through science" (''kexue jiuguo'') increased during the ROC period.

(CAS). In 1958, China completed its first vacuum-tube computer. Over the next several years, Chinese researchers expanded on these efforts with extrapolation from Soviet models. Following the Sino-Soviet split, China continued to develop domestic computing and electronic institutions, including the Beijing Institute of Electronics in 1963. Beginning in 1964, China through the Third Front construction built a self-sufficient industrial base in its hinterlands as a strategic reserve in the event of war with the Soviet Union or the United States. The Third Front construction was primarily carried out in secret, with the location for Third Front projects following the principle of “close to the mountains, dispersed, and hidden” ( zh, s=靠山, 分散, 隐蔽, p=kàoshān, fēnsàn, yǐnbì, labels=no). From 1964-1974, China invested more than 40% of its industrial capacity in Third Front regions. After Nixon's China trip in 1972, investment to the Third Front region gradually declined. Rapprochement between the United States and China decreased the fear of invasion which motivated the Third Front construction. Through its distribution of infrastructure, industry, and human capital around the country, the Third Front created favorable conditions for subsequent market development and private enterprise. In 1964, CAS debuted China's first self-developed large

companies. In 2016, China became the country with the highest science output, as measured in publications. While the US had been the biggest producer of scientific studies until then, China published 426,000 studies in 2016 while the US published 409,000. However, the numbers are somewhat relative, as it also depends how authorship on international collaborations is counted (e.g. if one paper is counted per person or whether authorship is split among authors). In 2022, China passed both the US and the European Union in the number of high-impact papers published. As of 2024, the Nature Index ranks seven Chinese universities or institutions in the global top ten for volume of research output. The Leiden Ranking rates six in the global top ten.
