1. An Overview of the Four Great Inventions

The "Four Great Inventions" (simplified Chinese: 四大发明) is a concept that originated with European scholars and was later adopted by the Chinese to highlight their civilization's technological prowess. The importance of these inventions was perhaps first discussed by the English philosopher Francis Bacon in 1620, who wrote of "Printing, gunpowder, and the compass" as mechanical discoveries that exerted great power and influence over human affairs. The modern list of four was popularized by the missionary and Sinologist Joseph Edkins in the 19th century and later expanded upon by the biochemist and historian Joseph Needham. These four inventions are not simply a list of ancient technology but are widely recognized as the innovations that laid the groundwork for the modern world.

3. Papermaking: A Writing Revolution

Papermaking is the process of making paper, a substance that is used universally today for writing and packaging. The origin of papermaking has traditionally been traced to China about 105 AD, when Cai Lun, a Han Dynasty official, created a sheet of paper using mulberry and other bast fibers along with fishnets, old rags, and hemp waste. However, archaeological discoveries have revealed that true paper was invented before 105 AD. Excavations of hemp paper made between the second and first centuries BC have been found in five different areas of China, proving that paper was in use well before the traditional attribution to Cai Lun. These papers were made from hemp and ramie, and microscopic analyses indicate that the fibers were processed with an alkaline solution and beaten, with the surface showing the use of a wove mold. Rather than being the sole inventor, Ts'ai Lun's role was to stimulate its development by producing paper from the paper mulberry shrub, which led to investigations of other plant fibers suitable for papermaking.

4. Printing: Mass Communication Begins

Ancient Chinese printing technology underwent two main stages: woodblock printing and movable type printing. Woodblock printing, invented in the Tang Dynasty (618-907), was a process of printing texts and images with ink by carving them onto wooden blocks. This technique had its roots in seal engraving and rubbing copies of inscriptions on stone tablets. The world's oldest surviving printed book, the Diamond Sutra, was printed in 868 using this method. During the Northern Song Dynasty (960-1127), the common artisan Bi Sheng invented ceramic movable type printing, an advance that appeared about 400 years earlier than Johannes Gutenberg's movable metal typeset printing in Germany. By 1000, paged books in the modern style had replaced scrolls, and two-color printing was seen as early as 1340. Printing spread eastward to Korea and Japan and westward via the Arab world to Africa and Europe, paving the way for the development of science and the Renaissance.

5. Gunpowder: The First Chemical Explosive

Gunpowder is considered one of the Four Great Inventions of ancient China. The prevailing academic consensus is that gunpowder was discovered in the 9th century by Chinese alchemists searching for an elixir of immortality. The Chinese name for gunpowder means "burning medicines," as the elements—potassium nitrate, sulfur, and charcoal—were initially studied for their medicinal properties. By the time the Song Dynasty treatise, Wujing Zongyao, was written in 1044, various formulas for gunpowder held levels of nitrate in the range of 27% to 50%. By the end of the 12th century, Chinese formulas had a level of nitrate capable of bursting through cast iron containers, leading to the earliest grenade bombs. Fireworks were invented in ancient China in the 12th century to scare away evil spirits, as a natural extension of this invention. Gunpowder spread to the West in the 13th century, and its weapons changed methods of warfare and accelerated the demise of the feudal system in Western Europe.

6. The Compass: Navigating the World

The earliest reference to magnetism in Chinese literature is found in a 4th century BC book called Book of the Devil Valley Master: "The lodestone makes iron come or it attracts it." During the Warring States Period, the Chinese people invented a device called a Si Nan, which was the earliest south-north direction-pointing device and the forerunner of the compass. By the time of the Tang Dynasty and the beginning of the Northern Song Dynasty, scholars had devised a way to magnetize iron needles by rubbing them with magnetite and suspending them in water. The first suspended magnetic needle compass was written of by Shen Kuo in his book of 1088. The compass was later introduced to Europe in the 13th century, where it offered technical assistance to navigators and ushering in the Age of Discovery.
