Four Great Inventions of Ancient
China
China held the world's leading position
in many fields in the study of nature, from the 1st century
before Christ to the 15th century, with the four great
inventions having the greatest global significance.
Papermaking, printing, gunpowder and the compass -
the four great inventions of ancient China-are significant
contributions of the Chinese nation to world
civilization.
Four Great Inventions of Ancient
China - Paper
China was the first nation to invent
paper. Before its invention, words were written on various
natural materials by ancient peoples-on grass stalks by the
Egyptians, on earthen plates by the Mesopotamians, on tree
leaves by the Indians, on sheepskin by the Europeans and
strangest of all, even inscribed on bamboo or wooden strips,
tortoise shells or shoulder blades of an ox by the early
Chinese. Later, inspired by the process of silk reeling, the
people in ancient China succeeded in first making a kind of
paper called "bo" out of silk. But its production
was very expensive due to the scarcity of materials. In the
early days of the 2nd century, a court official named Cai
Lun produced a new kind of paper from bark, rags, wheat
stalks and other materials. It was relatively cheap, light,
thin, durable and more suitable for brush writing. At the
beginning of the 3rd century, the paper making process first
spread to Korea and then to Japan. It reached the Arab world
in the Tang Dynasty, and Europe in the 12th century. In
the16th century, it went to America by way of Europe and
then gradually spread all over the world.
Before
paper was invented, Qin Shihuang, the first emperor in
Chinese history, had to go over 120 kilos of official
documents written on bamboo or wooden strips. A paper

Four Great Inventions
of Ancient China - Printing
Printed in Tang DynastyA
Buddhist sutra is the first book in the world with a
verifiable date of printing.
Before the invention of
printing, dissemination of knowledge depended either on word
of mouth or handwritten copies of manuscripts. Both took
time and were liable to error. Beginning 2000 years ago in
the Western Han Dynasty (206 B.C.--- 25 A.D.), stone-tablet
rubbing was in vogue for spreading Confucian classics or
Buddhist sutras. This led in the Sui Dynasty (581-618) to
the practice of engraving writing or pictures on a wooden
board, smearing it with ink and then printing on pieces of
paper page-by-page. This became known as block printing. The
first book with a verifiable date of printing appeared in
China in the year 868, or nearly 600 years before that
happened in Europe. In the Tang Dynasty (618-907), this
technology was gradually introduced to Korea, Japan,
Vietnam, the Philippines. Yet block printing had its
drawbacks. All the boards became useless after the printing
was done and a single mistake in carving could ruin a whole
block. In 1041-1048 of the Song Dynasty (960-1279), a man
named Bi Sheng carved individual characters on identical
pieces of fine clay which he hardened by a slow baking
process, resulting in pieces of movable type. When the
printing was finished, the pieces of type were put away for
future use. This technology then spread to Korea, Japan,
Vietnam and Europe. Later, German Johann Gutenberg invented
movable type made of metal in 1440-1448.
Four
Great Inventions of Ancient China - Gunpowder Credit for the
invention of gunpowder also goes to ancient China. Ancient
necromancers discovered in their practice of alchemy, that
an explosion could be induced if certain kinds of ores and
fuel were mixed in the right proportions and heated, thus
leading to the invention of gunpowder. In the Collection of
the Most Important Military Techniques, edited in 1044 by
Zeng Gongliang, three formulas for making gunpowder were
recorded; an explosive mixture of saltpeter, sulfur and
charcoal. Dr. Needham identified these as the earliest
formulas of such a kind. The method of powder-making was
introduced to the Arab world in the 12th century and to
Europe in the 14th. Gunpowder was originally used for making
fireworks and its later adaptation revolutionized warfare
across the world. Ancient necromaniers put minerals and
plants together, hoping to make some medecine to keep alive
forever

Four Great Inventions of Ancient China
- the Compass Sinan (Warring States Period)the
earliest guide tool in the world
The compass, an
indispensable navigational tool, was another significant
gift from ancient China. While mining ores and melting
copper and iron, people chanced upon a natural magnetite
that attracted iron and pointed fixedly north. After
constant improvement the round compass came into being. Dr.
Needham cites one of the first books to describe the
magnetic compass, Dream Pool Essays (1086) by Shen Kuo in
the Song Dynasty, about 100 years earlier than its first
record in Europe by Alexander Neekam in 1190. The compass
was introduced to the Arab world and Europe during the
Northern Song Dynasty (960-1127). Before its invention,
navigators had to depend on the positions of the sun, the
moon and the polestar for their bearings. The spread of the
compass to Europe opened the oceans of the world to travel
and led to the discovery of the New World. Thus, it was no
wonder that Francis Bacon, the English philosopher, pointed
out in his work The New Instruments, that the invention of
printing, gunpowder and the compass reshaped the world. In
his words, they outstripped any empire, any religious belief
and any heavenly body in exerting an impact on all humanity.
