Four Great Inventions of Ancient China

The Four Great Inventions of ancient China are the compass, gunpowder, papermaking, and printing. These inventions are celebrated in Chinese culture for their historical significance and as signs of ancient China"s advanced science and technology and contribution to the world that had tremendous effects on human civilization and development.

These four discoveries had an enormous impact on the development of Chinese civilization and a far-ranging global impact. English philosopher Francis Bacon once commented "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."

Compass

By the third century AD, Chinese scientists had studied and learned much about magnetism in nature. For example, they knew that iron ore, called magnetite, tended to align itself in a North/South position. Scientists learned to "make magnets" by heating pieces of ore to red hot temperatures and then cooling the pieces in a North/South position. The magnet was then placed on a piece of reed and floated in a bowl of water marked with directional bearings. These first navigational compasses were widely used on Chinese ships by the eleventh century AD.

Gunpowder

Imagine their enemy"s surprise when the Chinese first demonstrated their newest invention in the eighth century AD. Chinese scientists discovered that an explosive mixture could be produced by combining sulfur, charcoal, and saltpeter (potassium nitrate). The military applications were clear. New weapons were rapidly developed, including rockets and others that were launched from a bamboo tube. Once again, the raw materials at hand, like bamboo, contributed ideas for new technologies.

Papermaking

Chinese legend tells that the new invention of paper was presented to the Emperor in the year 105 AD by Cai Lun. Archeological evidence, however, shows that paper was in use two hundred years before then. Either way, the Chinese were significantly ahead of the rest of the world. The craft of papermaking relied upon an abundance of bamboo fiber to produce a fine quality paper. In China: Ancient Arts and Sciences, the papermaker uses only the traditional materials and methods to produce fine art paper.

Printing

The Chinese invention of moveable type, credited to Bi Sheng in the year 1045 AD, did not significantly impact Chinese society. Three hundred years later in Europe, Gutenberg"s development of moveable type revolutionized the Western world. Why? The Chinese language uses 3000 to 5000 characters in an average newspaper. The English language, in comparison, uses 26 characters in an average newspaper. Clearly, manipulating 5000 characters on a printing press took much longer than moving 26. Still, the invention of moveable type furthered Chinese technology and its role in the advancement of human civilization.
