Chinese Inventions and Astronomy By Kent Nishizawa The History of Chinese Inventions The Chinese people invented many wonderful things that are still being used today. In early and medieval China, scientists were interested mainly in engineering and practical inventions, so they invented many useful things. Chinese blacksmiths invented the crossbow about 450 BC, during the Warring States period. Paper was first invented in Han Dynasty China, 100 BC to 100 AD, and about the same time the magnetic compass for telling north from south, was also invented. Scientists in China also invented gunpowder. In 132 AD, Han Dynasty scholars built the first seismograph to tell you what direction an earthquake was coming from. During the Three Kingdoms period, about 250 AD, Zhu Ge Liang invented an early hot air balloon that people also used in war. These inventions show that the Chinese people were advanced in science and technology because they were hard to make. Why The Inventions Were Great The most famous inventions in the Chinese history were called “The Four Great Inventions of Ancient China,” which were papermaking, compasses, gunpowder, and printing. These inventions are special because they changed the people’s everyday life. They also had a huge impact on the development of Chinese civilization. For example, during The Warring States Period, the Chinese people had an advantage in the battles because they invented gunpowder which was used for exploding cannon balls. The wheelbarrow was invented in the first century to make chores easier to do. Soldiers used it to carry injured soldiers out of the battlefields. Farmers used it to carry crops to the market. Builders used it to move heavy supplies. Paper was invented in 100 A.D. and was made out of the mulberry tree. This invention made possible rapid changes in communications. The Great Inventors, Zhu Ge Liang Zhu Ge Liang was one of the most well-known inventors in Ancient China. He was also a remarkable politician, strategist, diplomat, and astrologer in the Three Kingdoms period. He assisted the emperor of The Shu Kingdom. He mastered many things like astrology, military science, and many other things. He invented a lot of popular things. Steamed buns Liang invented has become the Chinese staple food. Since Liang mastered military science, he invented few military items such as the repeating crossbow, the assault vehicle, and the battle array of the eight diagrams. Also, the kong ming chess was invented to entertain soldiers. The Most Popular Inventions #1 Compass Gunpowder The earliest-known compass dates back to the Han Dynasty. The Chinese people knew this invention as a “south-pointing fish” because this lodestone compass was pointing south. These compasses were primarily used for overland and ocean voyages. Gunpowder was invented in China, probably around the 1100. The Chinese doctors may have accidentally discovered how to make gunpowder while searching for ways to cure illnesses. Gunpowder is composed of about 75 percent saltpeter, 15 percent powdered charcoal, and 10 percent sulphur. Gunpowder was originally used for fireworks. The Most Popular Inventions #2 Kite Paper The kite was invented roughly 2,500 to 3,000 years ago. Besides China, Malaysia and Indonesia have claimed to be the original inventor of kite. Soldiers of the Han dynasty sailed kites to frighten their enemies. Also, kites were a popular way to celebrate festivals. Paper seems to have been invented around 100 B.C. in China. They were used for many different ways such as paper money and playing cards. The paper-making industry began under the Han Dynasty. The paper-making was a big success and began to be used all over China. The Most Popular Inventions #3 Silk Silk was a soft and light material much desired by the wealthy throughout the world. It became such a valuable export that the trade route running from Europe to China became known as the Silk Road. The Chinese people learned how to make silk from the cocoons of silkworms. They managed to keep the process for making silk a secret for hundreds of years until the Europeans smuggled the information out of China. Conclusion The Ancient Chinese people were very intelligent. They had special talents to invent different useful things. All those inventions have impacted human civilization all over the world from the past to the present. The most amazing inventions are found in China. I think that The Ancient Chinese had to make their own things since the country’s population is so large. Also there were people like Zhu Ge Liang who were fortunate to have lots of education in science and technology. I was really surprised when I learned how many things I use were invented by the Ancient Chinese people.
