Ancient China to contribute to basic human invention. Without them, the world may be family?.
Around the 6th century BC to the 13th century AD 1800, China inventors march in the forefront of the world. In many areas they create new technology, the long-term solution of the many problems plaguing human, technological inventions that human activities there have been major changes, this change has continued to this day.
6th century BC, the Chinese invented liquid pig iron smelting technology, the solution into the Iron Age of the human face after one of the greatest Inflatable castle problems, beginning with the simple method of iron ore into iron and pouring iron.
This invention allows mankind to the efficient and convenient supplies of iron ore into iron, this is the first human continuum of industrialization successful example.
Liquid pig iron smelting technology, the invention of a comprehensive update of the ancient Chinese tools, farm tools, and weapons and promoting the technological advances in many areas, for human manufacturing machines for the most important material conditions. Because of this difficulty smelting iron integrated high technology, the people's livelihood, the ancient Chinese rumor that the authorities strictly prohibited. Until the 15th century, only a Western liquid pig iron smelting technology.
At approximately the same time, summed up the ancient Chinese people since the Shang and Zhou has been the experience of casting bronze objects found that the main components of the bronze copper, tin alloy performance and the proportion of the relationship between the different uses for the metallurgy of various artifacts provide engineering Design basis. A book in the Spring and Autumn Period, "the test", a clear account of the six different copper, tin suitable for the respective proportions of the manufacturing artifacts, it is the history of mankind's earliest written the alloy composition and performance tables.
At the same time, the ancient Chinese invented a composite metal weapons manufacturing technology, using two different properties of the alloy ingenious combination of both sharp and the casting difficult broken sword. They first bronze casting with low toughness good sword core (of weapons experts called Jian Ji), and then high bronze sword wrapped a second casting core, a hard wear-resistant Fengren (sword called experts Shoulder).
Transcend the limitations of a single material, the use of composite materials and items, human engineering design is a leap in thinking that such new Inflatable castle ideas has been extended to today.
About the 4th century BC, the Chinese invented the compass. This invention was a human space ubiquitous position indicator, the earth will not lose our direction. 1800, Columbus and his sailors in the help of the compass, across the vast sea and found the American continent.
Water history of many major inventions were produced in a number of large construction projects, such as human rivers flow control of the new technology. 3 century BC, the ancient Chinese people dug a communication stream Yangtze River and Pearl River canal - Lingqu, technology projects to a new height.
In 219 BC, Qin Shihuang 500,000 troops to attack Guangdong blocked, in order to solve the Quartermaster especially food supply problems and life Supervisor Paul Ducao Yushi connectivity of the Xiangjiang River and the Lijiang River Canal to the Central Plains vessels Direct Lingnan. Lingqu The project took five years, the Yangtze River after the completion of the vessels can direct Guangzhou. This canal from 214 BC shoulder began shipping tasks, Hunan, Guangxi Railway until the opening of the 20th century, the years between 2000 and the Central Plains between Lingnan become an important traffic lanes, makes Wuling blocking the Yangtze River Valley and even the Pearl River Valley as a whole.
Lingqu construction of the Xiangjiang River in the north to the south and between the Lijiang River valley through the Xiangjiang River Valley Water platform Reply to Lijiang, with both transport and irrigation two functions. Yiqiao history of this water conservancy projects, including the three major inventions:
The first is the work of streaming technology.
The second is to make even the boulder into the
Inflatable castle overall technology.
The third is to make the ship from low level to high level of freedom of navigation technology.
2 century BC, that is, human invention Textile Technology in 5000, the ancient Chinese people in the use of natural plant fiber invented the other fiber products - paper.
The invention of paper, the text plug lightweight wings, with human thoughts and wisdom flying distance. Year 3 century, China's papermaking technique spread to North Korea imported 7th century Japan; 8th century Arab imported; 12th century into France; the late 15th century into the United Kingdom; 17th century, the United States imported from the United Kingdom.
Ancient Chinese people in the engineering and technical fields to create a lot of new things, and these inventions were many areas of today's technological base.
About 200 BC, the ancient Chinese invented the wheelbarrow. 1700, the Europeans wheelbarrow in the direction of the road and adding a wheel into today's bike.
At approximately the same time, the ancient Chinese people have successively completed ship propulsion and control technical aspects of the two major inventions created organize and rudder.
18th century, after the birth of the steam engine, propeller into installed in the hull on both sides, driven by the steam engine rotating paddle wheel; organize into deep underwater propeller. That the round has been eliminated, a propeller ship all mobile power source, and later became the most important early aircraft components.
China invented the rudder, clever use of lateral flow asymmetric thrust to produce their own water movement to change the direction of the hull moment and realize the ship power system and control system separation, shipbuilding and driving skills to make a significant milestone contribution. Use of the rudder control direction, this has become all the ships and aircraft of the basic model.
