Was there anything in ancient times that couldn t be made even with modern technology?

Yes, ancient bells and drums. Even today's technology doesn't have the means to make the exact same tone. Because of its precision and material combination, there is no way to surpass the ancient technology today.

No. Ancient things can be made in modern times, unless the production method is missing or the raw materials are not available.

For example, the handicrafts and textile industry in ancient times, because the technology was not so developed at that time, it was relatively backward, and some of them could not be made even with the current technology.

1. Bronze smelting and casting technology:

In ancient China, natural copper was originally used, and copper and tin alloys could be smelted by fire in the early Shang Dynasty.

of bronze. The process of smelting bronze is more complicated, probably the selected ore is added to the flux first, and then placed in the smelting furnace, burned charcoal for smelting, and when the fire is mature, the refined copper liquid is taken and the slag is discarded, that is, the primary copper is obtained. The initial copper is still relatively coarse, and it needs to be refined again to obtain pure red copper.

Red copper plus tin and lead are fused into alloys, that is, bronze.

The invention of bronze is a major event in the history of human civilization, because it overcomes the soft weakness of pure copper, and has the advantages of low melting point and good casting performance, it has gradually become the main variety of ancient bronze, and has promoted the development of manufacturing technology such as cars, ships, carvings, metal processing, agriculture, military and economic society. The application of bronze represents the level of science and technology and the level of culture and art at that time, and has become a distinctive symbol of this era.

2. Ancient cast iron technology:

The large demand for iron tools led to the invention of the iron fan (cast iron metal mold). In 1953, Hebei Xinglong Yanguo.

The iron fan unearthed from the smelting and casting site was used to cast iron axes, hoes, sickles and tools. These iron models are well-constructed, have uniform wall thicknesses, are consistent in shape and contour of the casting, and have been made with iron cores. Some Fan can cast two pieces of artifacts at a time, indicating that iron casting technology has reached a high level during this period.

Cast iron heat treatment.

There have been significant advances in technology during this period. Since the cast iron is smelted with charcoal, the carbon content is mostly near the eutectic point, while the content of other elements is low, which belongs to the purer iron-carbon alloy.

Many devices are cast with iron fan, and the wall thickness is generally 3 5 mm, which is a thin-walled casting. In practice, a more reasonable heat treatment specification has been adopted, so the quality of ductile iron castings is better. Most of the white-core ductile iron castings are completely treated, and there is little cementite residue and precipitated graphite.

Most of the black-hearted ductile iron castings are based on ferrite and pearlite, and some are based on ferrite or pearlite, and the shape of graphite is similar to that of modern similar materials.

3. Ancient steel casting technology:

Steel Filling Method, Ancient China.

An advanced steelmaking process invented by working people. It is one of the most outstanding achievements of China's early steelmaking technology. by Northern Qi.

Invented by the famous metallurgist Qimu Huaiwen. Before the 17th century, Western countries generally adopted the method of low-temperature smelting of wrought iron, which could not be melted, iron and slag were not easy to separate, and carbon could not penetrate quickly. After the development process of "block smelting" - 100 steelmaking - frying steel", China invented the steel filling method, successfully solved this problem, and made epoch-making contributions to the development of world smelting technology.

During the Northern and Southern Dynasties, a more technologically advanced steel filling method had appeared, and the weapons made with this method were tough and sharp. As early as the Han Dynasty, people began to use coal as fuel and used it to smelt iron. During the Northern Song Dynasty, the use of coal to smelt iron was quite common.

As a result, the temperature of the furnace is raised, which accelerates the smelting process and increases the productivity of the iron smelting industry.

The four great inventions of ancient China, papermaking, gunpowder, compass, and movable type printing. Wheelbarrow (wooden ox flowing horse), Zhuge crossbow.

Solar Storm – The earliest sunspot discovered.

There are stars in the Beidou - the observation of comets.

New Moon Xinmao Solar Eclipse - Solar Eclipse Record.

Sun, Moon and Stars – lunisolar calendar.

The world's oldest star catalog, the Shi's catalog.

The earliest and most complete calendar work in existence - the "Taichu Calendar".

Compass: Legend has it that the compass was invented by Emperor Xuanyuan of China in 2700 BC. The Yellow Emperor used a compass to discern the direction in the fog and defeated Chiyou.

According to historical records, the Chinese used the compass as early as the Warring States period. In the "Han Feizi" of the 3rd century B.C., it is said that during the Warring States period, people already used "Sinan" (compass).

1.Tianxingjian, a gentleman strives for self-improvement. As a gentleman, you should have a strong will, a never-ending spirit of struggle, strive to strengthen self-cultivation, and complete and develop your studies or career.

Zhang Heng, a famous mathematician in ancient times, invented the geokinetic instrument. Much more advanced than Western countries.

Geodynamics, papermaking, compass, gunpowder, printing, these are all these.

Like our ancient technology creation, like our country's paper-making art is very good.

The state of technology in ancient China was gunpowder wart.

Ancient Chinese papermaking technology was very advanced.

The four major inventions, just these four things can kill everything in seconds.

It shows that there are fewer people who die doing these things in modern times, at least for now, there is no need for those processes, and they can be completely replaced. With ancient crafts such as the Great Wall mausoleum, how many people have to die of exhaustion, and the number of people who die of exhaustion has been greatly reduced in modern times. The quality seepage is not as good as before because the manufacturing plant is cutting costs, and in ancient times, it was costless to do that thing.

It shows that there are a lot of Tongli technology has been lost, you must know that the ancient buildings have a lot of knowledge wheel laughter is very magical, they do not have the high-tech contained in the current but have built a lot of exquisite works that do not lose the present, and there are some works that we can't build now.

This incident illustrates the ancient technology, even more developed than today's technology, these ancient technologies also illustrate the dismantling of shirts, some of the words handed down in ancient times are also very reasonable, and the overall strength of the Chinese people should not be underestimated, if it is not for the limitation of materials, they or jujube may also be socks will play more strength.

This shows that although Chinese society is progressing, many lost technologies cannot be studied and there are no books to record them.

The main reason is that after a long period of research and development by human beings, there is no way to study some of the techniques of the ancient people, and these techniques are also because of the limited surrounding conditions, and it is difficult to master them in many cases.

Because there are many ancient technologies, although the technology is not advanced, but the action technology requirements are very chaotic and high, if there is no one to teach themselves, it is difficult to master these skills.

Because the wisdom of the ancients is infinite, and some of their technologies are so advanced that we can't study them even now.

China's porcelain-making process is unique in the world, China's porcelain has experienced more than 5,000 years of development and has made great contributions to China's development.

Ancient handicrafts were very powerful, such as ceramics. The purpose of studying ancient technology and culture now is to better understand history and pass on civilization.

Grave technique. Ancient cultural knowledge was protected by tombs, and without developed tomb technology, the value of these excavations would not even exist.

There are many reasons to spend a lot of money to study ancient times, for example, many cultural and traditional virtues in ancient times are worth learning from our descendants and verifying the existence of history.

Because to restore history, knowing the real technical level of people in a certain period of time helps us to see the natural law of technological development. For example, in ancient times, stone tools were used in daily life, and in the Shang Dynasty, there were more choices of bronze tools, and there were thousands of years between stone and bronze, and we simply do not know what specific factors occurred in the middle to lead to technological changes. If we know this reason, or the time node of technological change, with the long history of our China, we can find a pattern.

At that time, because science and technology were not modern developed, and the information obtained was relatively backward, people's mood was more peaceful, and they were much less disturbed, and they were completely immersed in studying something, and the effect achieved was incomparable to modern times.

On the one hand, the "technology research and development" department owned by the feudal aristocratic rulers has attracted many highly skilled artists to create, they have no worries about food and clothing, devote themselves to research and create, and better material conditions, so they have made exquisite works of art or scientific inventions.

On the other hand, it is the people, and it is based on this for survival, so it is also under the premise of survival needs, invention, creation and research.

These are all related to the precision of the times. In the era of war, art and handicrafts may not be developed as a whole, and there are no fine products, but in the prosperous era of national peace and security, such as the Tang Dynasty, when the people lived comfortably and richly, a large number of artistic masterpieces and scientific creations would emerge.

Because the ancients were more diligent and serious than we are now, and we rely on modern technology, brainpower, and manual work are not as good as them...

This is a historical complex that can witness the greatness of history. People in the world generally worship their ancestors, in the past when various conditions were not developed now, our ancestors were able to make many very beautiful things, and many of them are well preserved, enough for future generations to love and like, and crazy to collect.

I think there are actually quite a lot, for example, some of the mechanisms in many Huang Ling are difficult to make with our modern technology.

For example, the ground motion instrument made by the ancients cannot be done until now, and the 800-kilogram Simu Wuding made by the ancients cannot be done now.

Let's just say that the terracotta warriors and horses are what modern people can't do, and each terracotta warrior and horse has a different shape and expression, which is very unique.

It seems that there are no ancient techniques that cannot be done now. It's just that the methods are more advanced now than in ancient times.

In fact, I think that until now, we in China have not been able to do it, so that the corpse has no way to decompose for a long time, but in ancient times, it can, which we cannot surpass.

The ancients had a lot of technology that was very advanced, for example, China had a lot of bridges, and now it is very troublesome to build.

Now it can only be said that it is more advanced than the ancients, and with the development of science and technology, many things that could not be completed before can now be completed.

In ancient times, such as Tang Sancai in the Tang Dynasty, Luban's craftsmanship, bronze, the mausoleum of Qin Shi Huang can not be opened, and there are thousands of years of incorruptible mummies.

I think there are still some things, such as the environment, art, poetry and opera, calligraphy and painting, as well as etiquette, righteousness and shame, moral concepts, etc., which are superior to modern times to a certain extent, and in some respects modern times have not achieved higher achievements than ancient times.

First of all, I believe that the achievements of ancient times in art and literature are difficult to surpass in modern times. From the prose of Zhuzi in the pre-Qin period, to the Cifu of the Han Dynasty, Yuefu folk songs, and then to Tang poetry, Song Ci, Yuan Qu, Ming Dynasty, Qing opera, including calligraphers, painters, and so on in all dynasties, a group of outstanding and outstanding poets, lyricists, philosophers and artists have emerged, including a variety of exquisite works of art in ancient times are also difficult to achieve in modern times.

Their works have been passed down through the ages, and they are the bearers and transmitters of the long history and culture of the Chinese nation, and the cultural heritage contained in them is endless. Although there are many excellent literary and artistic masters in modern society, in general, I think it cannot be compared with ancient times.

Secondly, the natural environment cannot be compared. The current environment is not as good as in ancient times, the air is fresh in the past, the rivers are clear, there has been no industrial and chemical emissions and pollution, all kinds of raw poultry have not been hormones, vegetables and fruits have no pesticides, everything is pure natural, pure green, and it is definitely healthier than modern times. However, with the development of the times, the progress of science and technology will inevitably pay some costs, and now we are also trying our best to improve and protect the natural environment.

In addition, I think that the concept of etiquette, righteousness, and morality is not as good as in ancient times. Nowadays, when it comes to rules, etiquette, and virtue, there will always be many people who jump out and say, "It's 9102, and the Qing Dynasty is dead" and so on, but I want to say that this is not a reason for us to be unruly and not to be virtuous. It is true that there is a lot of dross and things in ancient cultures that need to be discarded, but at the same time, there are many things that do need to be passed on.

Nowadays, many people have a bad outlook, bad words and deeds, and violate basic morality, and they really need to learn the traditional morality of ancient times.

The Great Wall built in ancient times, the large stone slabs have thousands of catties, and there is no way to transport this kind of stone slabs to the mountains and mountains with the manpower and material resources of modern society.

A lot of wisdom in ancient times cannot be surpassed in modern times, including many treasures caused by natural conditions, such as if the national treasure can talk about the plain yarn single clothes, the modern silkworm baby because of hormones and other modern reasons, the top silk can not reach the lightness of ancient times.

I think the most important point is that people's eyesight is not as good as in ancient times, and people's eyesight was very good in ancient times, and now many electronic products cause people's eyesight to decline very seriously.
