Science, Technology and Civilisation in China
This commentary attempts to build on the PowerPoint presentation and provide more detail about the
topic. I cannot do justice to the theme because of the time constraints and the immense amount of
material relating to the topic.
One of the most fascinating aspects of Chinese history is the significant advances made over many
thousands of years in astronomy, mathematics, science and technology. Many of these discoveries and
inventions were made long before similar advances in the West. For example gunpowder, the magnetic
compass movable type printing and paper making were all invented before appearing in Europe.
Ancient Chinese mathematicians, scientists and technologists realised through careful and systematic
observation and experimentation major discoveries in disciplines such as astronomy, mathematics,
medicine, science and technology. The true extent of this is just beginning to be accepted by the West.
Confirmation and validation of these achievements are being made continually as more archaeological
and new literary evidence is discovered. Many of these developments can be mapped to a number of
determining factors such as social unrest, wars, needs to improve the infrastructures for transportation
and communication. In the case of China a number of historians have also highlighted other factors such
as the nature of the Chinese landscape its vastness and exposure to extreme weather conditions. Its
long rivers, numerous mountains and plateaux required land management techniques to be developed
to produce sufficient crops. Very effective irrigation systems were established along with crop rotation
and rice production methods. The Chinese also referred to crop rotation as alternating fields. Irrigations
schemes included artificial lakes, canals, dams, embankments and sluice gates.
A system of canal locks and pounds is shown below.
These achievements occurred and span practically all the dynasties from
pre-history. For example a number of innovations were made in metallurgy
during the Zhou dynasty (c 1045-256BC) including the development of steel
and wrought iron using forging and puddling techniques. The crossbow
was in use during the Warring States period which according to Joseph
Needham (see below) was a groundbreaking invention. Gunpowder was
recorded in 330AD by Ge Hong.
Picture on the left opposite shows a crossbow from the Warring States
period 403-256 BC.
The Han Dynasty (206BC-220AD).
The Han Dynasty witnessed the development of a seismograph, improved
irrigations systems, the silk loom and kite and air balloons.
The Tang Dynasty (618-907).
The Tang Dynasty also witnessed another period of great innovation and discovery. Printing was first
recorded in the Tang Dynasty. Book printing was developed in China and it is also important to note that
this also occurred in Japan and Korea. This period saw advances in traditional Chinese medicine with the
publication of several seminal compilations on the medicinal benefits obtained from animals, cereals,
fruits, herbs, minerals, plants, vegetables.
The Song Dynasty (960-1279).
The Song Dynasty witnessed a period of relative stability after a century of civil
war which encouraged an era of modernisation and innovations. Greater
freedom facilitated scientific development, economic reforms and achievements
in the arts and literature. Overseas trade expanded and with greater wealth the
mints produced 5 billion coins in 1088 AD and the first banknotes were produced
in 1032. Minted coins were made of mixtures of copper and tin to create a
bronze alloy. The picture shows a multitude of metal artefacts made in iron, steel
and bronze.
Also during this period maritime engineering rapidly developed associated with
overseas trading e.g. the use of dry docks for repairing ships .Various writers
proposed theories associated with geology and climate change. Su Song with other scholars produced a
pharmaceutical treatise dating from 1058-1061 including interrelated topics on botany, mineralogy,
metallurgy and zoology. Su Song also made significant advances in the technology of clock design and in
the theories of horology. The period also witnessed developments in astronomical observation e.g.
super nova explosions and comets. Experiments were also made in developing the camera obscura and
the invention of the movable type printing. The picture below on the left shows a person operating
movable clay type printing during and after the Song Dynasty 960-1127.
Advances also made in metal forging and mathematical theories associated
with spherical trigonometry and number theory.
The Yuan Dynasty (1279-1368).
The mogul rule under the Yuan Dynasty witnessed advances in economics
with the first mass production of paper banknotes. A number of links were
established at this time between Europe and China driven by various wars and alliances between the
Franco-Mogul. Chinese knowledge of gunpowder and siege warfare was transmitted to Arabic and
European countries during this period. Chinese and Arabic astronomers worked together at the Chinese
Astronomical Bureau establishes by Kublai Khan as well as working at the Persian Maragha observatory.
Even earlier Indian and Chinese astronomers had exchanged expertise with each other.
Taoism heavily influenced the development of the Chinese nation and was very associated with research
into alchemy and as a result discovered many new dyes, metal alloys and types of porcelain.
The Jesuits missions of the 16th and 17th centuries introduced Western astronomy, science and
technology into China as well as transmitting Chinese developments to Europe. This was during the
latter end of the Ming Dynasty (1368-1644). The works of Confucius were translated into European
languages which subsequently influenced European philosophers e.g. Goethe and Quesnay.
The English philosopher Francis Bacon said ‘that the three discoveries of printing, gunpowder and
compass changed the whole face and state of things throughout the world; first in literature, second in
warfare, third in navigation; whence 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.’
Many commentators have agreed ’that the failure of modern science to develop in China in the
18th/19th centuries was due to the differences in the social and political structure and environment
and not inherent ineptitude of the Chinese for science’. (Fu Ssu-Nien (Sinien)). Also interference and
intervention from Western nations in the 19th century – the century of humiliation- did not help e.g.
Opium Wars and the Boxer compensation etc.
People’s Republic of China 1949+
Since the establishment of the People’s Republic China has designated science and technology as one of
the Four Modernisations. A few examples of their achievements and scientific research include high
speed trains, satellite launching, space travel, improved rice production and alternative technologies
particularly associated with energy generation. China is now at the forefront of high tech patent
registrations.
Joseph Needham (1900-1995) - Chinese name was Li-Yuese.
No other person was more influential than Joseph Needham in bringing the world’s attention to these
Chinese achievements.
Joseph Needham was a remarkable individual, a noted scientist-biochemist, historian and sinologist.
Educated at Cambridge University specialising in embryology and morphogenesis following his postgraduate studies. In 1937 three Chinese research students came to work with him; Lu Gwei-djen, Wang
Ying-lai and Chen Shi-zhang . As a result he became fascinated by China particularly the history of
science and technology and learnt Classical Chinese and the language being tutored by Gustav Halous a
colleague from his college at Cambridge. As a result of this interest in China he decided to write a large
compendium of the history of Chinese science, technology and medicine.
In 1942 he was sent to China to establish links with scientists and create a Sino-British Science Cooperation Office initially based in Chongqing (Sechuan). At the time Japan was invading China and the
British saw China as an ally against the Axis powers so this initiative was part of a strategy to strengthen
cooperation between China and the West. In spite of the challenges that Needham had to face he was
delighted to be able to stay in China for three years and travel freely as much as the Japanese presence
would allow. His longest trip was to the far west in Xingjiang at the caves of Dunhuang located at the
end of the Great Wall where he found the first printed coy of the Diamond Sutra. He was able to build
on his already extensive knowledge of Chinese culture and history and quickly establish excellent
relationships and respect with the Chinese scientific and artistic communities and beyond including
political figures e.g. Zhou Enlai. He became great friends with Wang Ling a noted historian who became
one of his major collaborators on the Science and Chinese Civilisation (SCC) project. During his time in
China he collected an immense amount of material much of which was freely given be the Chinese. The
Chinese continued to send him massive amounts of documents and manuscripts when he returned to
Cambridge. In 1948 he proposed his project to the Cambridge University Press who agreed to publish
the material. All this material along with records he made in China talking with scientists and historians
provided the basis for the publications. The first volume was published in 1954.
In 1946 helped to found UNESCO – actually establishing the S in the title (S for Science) and was the first
head of the science division of the organisation. In 1948 he returned to Cambridge and taught
biochemistry but began to devote the majority of his time to the SCC project. In 1966 he became master
of his college and was relieved of all his teaching and research work on biochemistry and was then able
to spend all his energies on the project. He was joined by colleagues including u Gwei-djen along with
other researchers. He wrote 15 volumes himself and later collaborated with other researchers until his
death in 1995. The planning and preparation of the series continues.
He received many honours from around the world. A Joseph Needham Research Institute was
established in 1985 in Cambridge to continue his work.
