What are some of the lost ancient technologies? 70

Chimes that can only be reproduced by a computer: The technological characteristics of bronze chimes in the Western Zhou Dynasty of China, especially the peak of chimes in the Western Zhou Dynasty, the Chimes of Zeng Hou Yi, are designed and manufactured according to the accurate laws of scale. Four of them are arranged according to the core scale of the "Kakuzaki Hanomiya", and the scale between the bells is extremely precise.

However, after the Western Zhou Dynasty, the level of chime manufacturing has declined. The chimes of the Eastern Zhou Dynasty, except for the four core scales of the "Jiaozheng Yugong", the other scales are no longer accurate.

Ancient people used diamonds to polish jade: As early as the Neolithic Age, more than 6,000 years ago, Chinese ancestors were already using diamonds and corundum to process jade ornaments. Researchers use modern physical methods to prove that the Chinese were the first to use diamond and corundum, and the skills they once mastered were difficult to achieve with modern processing methods.

Chinese Spiral": The oldest known jade ring with spiral patterns unearthed from the Spring and Autumn Chu Tomb in Xichuanxia Temple, Henan Province, was shown to him. The owner of the tomb died in 552 BC.

Analysis of the 10 spiral grooves on this 27 mm diameter jade ring showed that they were in perfect agreement with the "Archimedes Spiral". The technology to make a similar device existed around 550 BC.

Furlong machine. Then there is the 28-round Lianzhu fire gun invented by Dai Zi.

"Beaded Firebolt", which can store 28 projectiles after a single load. The mechanism of the "Bead Gun" is very ingenious, and the two steps of firing and loading the projectile can be carried out in tandem, thus simplifying the reloading procedure and greatly increasing the firing speed. As a result, Kangxi exiled Dai Zi to Shengjing (present-day Shenyang).

There, Dai Zi lived a difficult life for more than 30 years, and was forced to sell calligraphy and paintings to make a living, "often lying on the cold kang in the winter night, and wading into the mountains to collect hazelnuts in the early morning to cure hunger." It was not until Dai Zi was 77 years old that he was pardoned by the emperor, and soon died of poverty and illness. After Dai Zi's death, the repeating firearms he invented did not become the large-scale equipment of the Qing army, and could only be "hidden at home", and gradually disappeared after the Qianlong Dynasty, leaving great regrets to the Chinese.

I have the impression that there was a kind of crane that was used to build bridges, similar to today's cranes, but with much more power than today's cranes, and without today's power equipment. It seems to have been mentioned in a book about the construction of ancient bridges, and in that book it was said that there was no way to verify it. Only bridges built with it can be verified.

Song Dynasty - official porcelain.

The family has a lot of money, and it is not as good as a piece of official porcelain.

Ancient people were very wise, they invented a lot of technology during that period, and there are still many technologies they invented that cannot be restored with modern technology. Although there were no convenient and intelligent machines like in ancient times, they were all black technology created by the most primitive handmade during that period. Next, I will introduce you to a few ancient technologies that even modern people cannot restore.

The first is Damascus steel, which is a kind of steel made of iron materials made of different kinds of materials, which is synthesized by refining, and has a very special pattern engraved on the surface when casting, which is also called pattern steel. Modern scientists have analyzed that this material is made of steel with a very precise amount of compounds, which is a very advanced technology, but its casting method is still a mystery. The second is Roman concrete, which is a very important material in construction, and is used in many buildings, and it is characterized by being very hard and strong.

However, this kind of concrete is formed by a special chemical reaction, and it takes a long time to make, so it cannot be used in modern society. <>

The other is flexible glass, which does not look much different from ordinary glass, but does not break. There is also the Greek fire, which is a liquid fuel and other fires, except that this fire burns in contact with water and does not need to be ignited. In that period when there was no gunpowder, this kind of fire can be said to be the most lethal one**.

The last one is the Archimedes ray, also known as the death ray, which is used in warfare and is a very powerful **. But when the Romans invaded Syracuse, they killed so many Archimedes that the Archimedes were gone, and no one has been able to study them since. <>

It can be seen from this that the wisdom of the ancient people was to be able to create so many things with their hands, which is really admirable.

Lu Ban was a native of Lu during the Spring and Autumn Period, also known as Gong Loser. Legend has it that Luban made a big wooden bird based on the birds in the sky, and people called it a wooden kite. It is said that Lu Ban rode on the bird, and then patted its head three times, it will fly, and can also control its direction, there are written records, in the late Spring and Autumn Period, Lu Ban took the wooden kite at that time and peeped into the capital of the Song Kingdom.

Smelting and casting, tenon and tenon technology, ground motion instrument, ancient aircraft, gold sore medicine, hemp boiling powder and other production techniques cannot be restored.

The four major inventions, the first instrument, textile technology, traditional Chinese medicine, astronomy and so on.

Traditional Chinese medicine (traditional Chinese medicine) generally refers to medicine based on traditional medicine created by the working people of the Han nationality in China, so it is also called Chinese medicine. It is a discipline that studies human physiology, pathology, and the diagnosis and prevention of diseases.

Traditional Chinese medicine was born in a primitive society, and the theory of traditional Chinese medicine has been basically formed in the Spring and Autumn Period and the Warring States Period, and has been summarized and developed in successive dynasties. In addition, it has had a profound influence on the countries in the Chinese character cultural circle, such as Japanese Kampo medicine, Korean Korean medicine, Korean Korean medicine, and Vietnamese Eastern medicine, all of which were developed on the basis of traditional Chinese medicine.

Traditional Chinese medicine carries the experience and theoretical knowledge of the ancient Chinese people in the struggle against diseases, and is a medical theoretical system gradually formed and developed through long-term medical practice under the guidance of ancient simple materialism and spontaneous dialectical thinking.

Traditional Chinese medicine takes the five elements of yin and yang as the theoretical basis, regards the human body as the unity of qi, form and spirit, and explores the pathogenesis, disease nature, disease location, analysis of the pathogenesis and the changes of the five internal organs, meridians and joints, qi, blood and fluid in the human body, and then derives the name of the disease, summarizes the syndrome type, and formulates the treatment method of "sweating, spitting, lowering, harmony, warming, clearing, replenishing, and eliminating" with the principle of syndrome differentiation and treatment, and uses traditional Chinese medicine, acupuncture, massage, cupping, qigong, diet therapy, etc. means, so that the human body to achieve the harmony of yin and yang.

The positive side of TCM** is the hope that it can help restore the balance of yin and yang in the body, while the negative side is the hope that when drugs must be used to slow down the progression of the disease, it can also take into account the quality of life and life.

The farming technique of oxen dragging wooden ploughs, the rolling technology of donkeys pulling stone mills, the technique of improving the quality of plants by grafting, and the technique of curing diseases by eating Chinese herbs are all techniques that have existed in ancient times and have been left over to this day.

The ceramics are burned, but they are all private kilns, and the technology of the official kiln has been lost.
