What was the black technology of the Han Dynasty?

The wisdom of the ancients is far beyond our imagination, and the science and technology of the Han Dynasty shines even brighter. For the development of science and technology in the Han Dynasty, I don't know it, and I am shocked when I see it. Today, let's take a look at the black technology of the Han Dynasty.

1. The invention and improvement of papermaking. During the Western Han Dynasty, silk wool and hemp had begun to be used to make paper, which is the distant ancestor of paper. Cai Lun of the Eastern Han Dynasty improved papermaking, which brought about a revolution in writing materials.

Caihou paper is easy to carry, widely used, high quality and low price, and has promoted the cultural development of China, Arabia, Europe and even the whole world. Therefore, the papermaking of the Han Dynasty became one of the four great inventions of ancient China.

2. Astronomy and medicine in the Han Dynasty developed by leaps and bounds. Zhang Heng, a great scientist and astronomer in the Eastern Han Dynasty, invented the first wind and ground motion instrument that can monitor the best weather, and also invented a large number of black technologies such as water leakage to armillary sphere, Rui wheel pod, and solo flying wood carving, which is breathtaking! In terms of medicine, Zhang Zhongjing, a medical saint of the Eastern Han Dynasty, created "Treatise on Typhoid Fever and Miscellaneous Diseases", and Hua Tuo, a divine doctor, invented Ma Boiling Powder, becoming the first person to use anesthesia in China.

Third, the rapid development of mathematics has laid the foundation of mathematics in ancient China. The Western Han Dynasty's "Zhou Ji Sutra" and the "Nine Chapters of Arithmetic" in the early years of the Eastern Han Dynasty are masterpieces in the field of mathematics, especially the "Nine Chapters of Arithmetic" is a summary of the development of mathematics in the Warring States, Qin and Han dynasties, including the four operations of fractions, the present has the technique (called the three-rate method in the West), the square and the square (including the numerical solution of quadratic equations), the surplus and the deficit (called the double method in the West), various area and volume formulas, the solution of linear equations, the addition and subtraction of positive and negative number operations, the Pythagorean solution method and other calculation methods. It formed an independent system centered on calculation, which was completely different from ancient Greek mathematics. With "Nine Chapters of Arithmetic" as proof, who would dare to say that China's mathematics comes from the West?

Fourth, in the invention of process technology, the Han Dynasty has made a qualitative leap. China's ancient ceramic skills appeared as early as the Xia, Shang and Zhou periods, but it was not until the Han Dynasty that China's porcelain was really fired era. The Han Dynasty also invented a large number of black technologies such as distillation, hydraulic mills, prototypes of modern horse yokes and belly belts, lacquerware, reciprocating piston bellows for metallurgy, wheelbarrows, waterwheels, and suspension bridges.

In addition, the smelting technology of the Han Dynasty has also advanced by leaps and bounds, and the bronze translucent mirror known as the "Han Dynasty Magic Mirror" has appeared. Distilled spirits also appeared in the Han Dynasty, and the level of winemaking was perfected. In the Eastern Han Dynasty, new irrigation tools such as water drainage appeared, and agricultural technology was greatly improved.

Science and technology is the primary productive force, the Han Dynasty is the era of rapid development of science and technology in ancient China, a large number of black technology emerged, so that we have to marvel at the wisdom of the ancients. It is their genius and creativity that have promoted the progress of society and achieved the glory of Chinese civilization. Finally, let's call for them!

The main reason for the prosperity of science and technology and culture in the Han Dynasty was the unification of the country; Economic development; co-creation by all ethnic groups; Frequent exchanges between China and foreign countries; Inheriting and carrying forward the traditions of previous generations, etc.

The culture of the Han Dynasty and the Han Dynasty was formed and developed on the basis of the culture of the hundred ethnic groups. Chinese characters, Chinese language, and Chinese culture are all a new type of culture formed after long-term exchanges and integration, removing the rough and extracting the fine, and removing the false and retaining the true.

In particular, after the improvement of the two "great unifications" of Qin Shi Huang and Liu Bang of the Han Dynasty, a new cultural prototype was basically formed. After the practice of Emperor Wen, Jing and Emperor Wu, it has become a relatively stable national culture.

In addition, the vigorous development of political, economic, military, diplomatic, scientific and technological, and cultural undertakings during the Han and Han dynasties had a profound impact on history, thus forming the specific title of "Han people, Chinese language, Chinese characters, and Chinese culture".

1. Four hundred and seven years; The last emperor, Emperor Liu Xie, Han Xian.

2. The Han Dynasty was a unified dynasty after the Qin Dynasty, divided into the Western Han Dynasty and the Eastern Han Dynasty, with a total of 29 emperors and a pure burning group enjoying the country for 407 years. The last emperor of the Eastern Han Dynasty, Emperor Liu Xie, was controlled by Cao Pi in 220 AD and was forced to surrender to Cao Pi, and the Eastern Han Dynasty perished.

3. Science and technology of the Han Dynasty.

Papermaking In the Western Han Dynasty, Duan Qing began to use silk wool and hemp to make paper, which was the distant ancestor of paper, and Cai Lun in the Eastern Han Dynasty improved papermaking and formed paper in the modern sense. Papermaking became one of the four great inventions of China.

Astronomy and medicine, Zhang Heng of the Eastern Han Dynasty made the world's first weather weather motion instrument that can predict the best weather. The "Taichu Calendar" formulated by Luoxiahong and others included the 24 solar terms in the calendar for the first time.

Zhang Zhongjing is revered as the "saint of medicine" and the ancestor of Chinese medicine because of "Treatise on Typhoid Fever and Miscellaneous Diseases". According to historical records, Hua Tuo was the first doctor in the world to use general anesthesia.
