Ancient China Essays - Steelmaking, Building Materials, Free Essays Ancient China The World is forever in debt to China for its innovations. Ancient China was extreme advance and many of its discoveries are still in use today. This is what Robert Temple, the author of The Genius of China 3000 years of science, discovery and invention. The book is based on 11 main parts of Chinese innovation. Within these 11 categories, there are 3 main parts that contain the most significant inventions. Robert Temple concentrates the bulk of his examples in these three categories, agriculture, domestic and industrial technology , and engineering. Temples examples were not limited to these fields of innovation. The Chinese excelled in many other areas, including mathematics, warfare and transportation, to name a few. Although Temple wrote about eleven fields of invention, I feel that these three sections contain the greatest examples of Chinese innovation, and the debt that the modern world owes China. The first main area is the field of engineering. Within this chapter, the development of iron and steel is the greatest achievement. The development of iron and steel led to other advances. By at least the 4th century the Chinese have developed blast furnaces to obtain cast iron from iron ore. This was 1200 years before the first blast furnace showed up in Europe. The reasons that the author gave to explain the reasons why the Chinese developed this technology are simple. The Chinese had access to large amounts of clay, the key ingredient in making blast furnaces. The Chinese also figured out that by adding a substance they called :Black Earth, they could lower the melting point of iron. Another major invention of the Chinese, that led to other achievements, is steel. The common belief today is that Henry Bessemer discovered the process of refining iron into steel. The fact is Chinese had developed the process to refine iron into steel in the second century BC The Chinese learned that by injecting oxygen into the blast furnace, they could remove the carbon from the iron. The Chinese called this process the hundred refinings method since they repeated the process that many times. The finished product was highly prized in China for its strength and ability to hold an edge on a sword. The Chinese would weld the steel onto weaker iron thus creating a strong edge and a superior weapon. The Chinese iron and steel workers were the best at making different types of metals into modern times. But then, no one else could have done so at the time, since iron existed nowhere else but in China. The Chinese invented the chain pump in the first century AD The chain pump allows water to the pumped from lower to higher elevations. The chain pumps were used for draining and pumping in civil engineering, but what is more important is it was used for irrigation. Irrigation allows for greater and more intense farming, thus resulting in a better crop yield. With the greater crop yields larger populations can be supported. The chain pump was exported to all parts of the world by way of visiting ambassadors and dignitaries. The first European chain pump appeared in the sixteenth century, and was a direct copy of the Chinese version. The second area of great Chinese achievement is in domestic and industrial technology. The most recognized Chinese invention is in the field of domestic and industrial technology, paper. Paper was invented around the second century BC and was used as clothing. One might not believe that paper could be used as clothing, but the paper made at that time used thicker and tougher paper fibers. Not only was paper used for clothing, it was also used for military body armor. The Chinese found out that pleated sheets of paper could stop the penetration of arrows. The paper armor was standard issue with Chinese land and sea units. Papers writing property was not discovered till about one century after its discovery. The earliest example of writing on paper was found an abandon military post. The paper found dates back to 110 AD and contained two dozen readable characters. The area that let China grow and expand was the innovations in the area of agriculture. The greatest achievement
