Can you explain the situation of the compass's invention, development, application, and spread in China?

Development history: During the Warring States Period, people used the characteristics of magnets to indicate the north and south to make a guide tool Sinan.

In the Song Dynasty, the working people mastered the technology of making artificial magnets, and made guide fish.

At the end of the eleventh century, the compass began to be used for navigation.

In the Southern Song Dynasty, the magnetic needle and the azimuth device were assembled into a whole, which was the compass.

In the Yuan Dynasty, there were man-made needle-type compass turtles and compass fish.

The use recorded in ancient books:

The boat master knows geography, stargazing at night, observing the sun during the day, and obscurively observing the compass".

Boats come and go, but the compass is the rule, day and night to watch carefully, the slightest difference, better than the tie."

Biography: At the end of the Northern Song Dynasty and the beginning of the Southern Song Dynasty, around 1180), the Chinese compass (or compass) was introduced to Europe through Arab merchants.

In the 7th century B.C., the book "Pipes and Numbers" recorded: "Those who have magnets on them have copper and gold on them." It means that if there are magnets on the mountain, there is iron ore hidden in the mountain.

In the geographical masterpiece "The Classic of Mountains and Seas", it was also recorded that "there are many magnets in the mountains". "Water Jing Note" records that in front of the Afang Palace of the Qin State, the gate is made of magnets to prevent someone from entering the palace to plot assassination, such as the bad guys secretly wearing armor and hiding weapons into the palace, they will be sucked by the door and discovered, which shows that the people have discovered the iron absorption of the magnet very early and made use of it.

As early as the Warring States period more than 2,000 years ago, people used the characteristics of magnets to indicate the north and south to make a guide tool Sinan. However, what Sinan was like during the Warring States period cannot be verified. The illustration "Sinan" in the textbook "Chinese History" is based on the "Sinan Model of the Han Dynasty" exhibit in the Chinese History Museum.

This model was made by later generations based on historical records and Han Dynasty sites unearthed underground. The floor is made of bronze, with a round inner and outer square, and the central round surface is ground very smooth to ensure the accuracy of the direction indicated by the spoon. On the periphery of the central circle, there are eight trigrams, heavenly stems, earthly branches, and twenty-eight nakshatras, a total of 24 directions.

The small spoon in the center of the site is ground with a whole piece of natural magnet, the positive pole of the magnet is ground into the long handle of Sinan, and the bottom of the spoon head is hemispherical, which is very smooth. When using, first put the ground flat, then put Sinan in the middle of the site, pluck the spoon handle with your hand to make it rotate, and wait until Sinan stops, the direction of the spoon handle is the south. This spoon-shaped sinan was still in use until the eighth century.

Compass. It is one of the four great inventions of our country.

One of them, we not only have to learn the relevant knowledge of the compass, but also learn how to use the compass, the compass has also brought great benefits to the development of our world, so what are the specifics?

In ancient times, the compass was something that could be pointed, just like when Zheng He went to the West.

, also use a compass to point the way. Because we don't have any iconic objects to guide us on the sea, the presence of a compass is very important at this time. Therefore, in navigation, the compass can be said to be the most important single invention.

The sea route was also a very important hub in ancient times, so the invention of the compass also promoted the world's largest countries.

The compass is not only to promote the best of all countries, but also to promote the exchange of countries. The compass was later introduced to other countries from our country, which also brought some help to other countries, and now the compass is widely used all over the world. It also brings a lot of help to everyone, just like having a compass in the mobile phone, which is also to allow us to find the direction in some special environments when there is no network or no other way.

Especially when you're in the desert or the ocean, the compass is like a lifesaver.

So the compass has been invented for a long time, but it is still widely used, which shows that it is a very useful thing in the development of the world. At the beginning of the invention, he promoted the best and cultural exchanges between countries, so with the development of the world, in fact, there are more high-tech things that can replace the position of the compass, but the compass is the most primitive way after all, when the high-tech thing loses the support of electricity or other things, it will be useless. So we still need to rely on the compass at this time, so in the process of world development, the compass has not been eliminated.

On the contrary, when it comes to adventure, a compass is still a must-have.

The advantage is that he has already pointed out the direction of the Fangshou Cave, which facilitates people's lives, distinguishes between the southeast and northwest, finds the direction, and can confirm their own travel route. Moreover, it can promote the development of navigation, promote the progress of society, and also improve the ability of navigation, which plays a huge role, can promote the progress of navigation, and promotes the development of trade.

It can better judge the direction, and it is very important to take the core of the elimination of the core in navigation, which can better drive on the ocean, promote the development of the field of marine fighting, and prevent getting lost.

It can promote the development of navigation, promote the progress of the society, and also improve the ability of navigation, which has played a huge role in promoting the progress of navigation and promoting the development of trading and demolition.

The benefits are that it points out the direction, facilitates people's lives, distinguishes between the southeast and northwest, finds the direction, and can confirm their own travel route.

The compass can promote the sea.

The invention of the "compass" was established as one of the "four great inventions" in ancient China, and it was a demonstration of the wisdom of the ancient people in China. The discovery of the "compass" helped China solve many travel and navigation problems in ancient times, greatly expanded foreign exchanges, stimulated the connection between each other, and promoted the economic and cultural development of both sides.

When the invention of the "compass" first originated and there is still no accurate answer. There is a saying** Cui Bao in the Western Jin Dynasty "Ancient and Modern Notes" said: "The Yellow Emperor and Chiyou fought in the field of Zhuolu.

In this campaign, the invention was made in addition to the compass. So according to historical documents, around 2700 BC, the Xuanyuan Yellow Emperor of China invented the compass. The Yellow Emperor used a compass to discern the direction in the fog and defeated Chiyou.

But now the world's public opinion is that the compass, one of China's four major inventions, was invented in the Warring States Period, which has a history of more than 2,000 years. But at that time it was not called a compass, but a sini." "Sinan", I believe everyone has heard of the word, but why is it called Sinan?

According to historical records, the inventor at that time polished the natural magnet into a spoon shape, placed it on a smooth surface, this spoon-shaped magnet will automatically turn to rest, and the spoon handle points to the square due south, so the name "Sinan" is brought from this.

All in all, the invention of the compass has gone through many processes, and his invention is a demonstration of the vigorous development of China's history and culture, and the crystallization of the wisdom of the ancient people of China. The compass is also the result of the ancient Chinese working people's understanding of the magnetism of magnetism in their long-term practice and labor.

As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization. And in ancient China, he has many functions, the compass can be used in sacrifices, rituals, and later gradually also used in military and divination and feng shui to determine the direction, its wide range of uses, all show the prosperity of China's ancient civilization.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the north pole of the magnetic needle points to the north magnetic pole, and the direction can be identified by using this performance. The invention of the compass (also known as the compass needle) has played a great role in the development of human social history, the progress of science and the cultural exchanges between the East and the West. In the past, when we sailed in the vast ocean, flew in the blue sky, commanded operations on the battlefield filled with gunpowder, and toured and interacted with foreign countries, because we did not have scientific pointing instruments, we sometimes either lost our way or turned around, which caused great impact and losses on navigation and operations.

Since China took the lead in inventing the compass after a long period of social practice, various situations have been very different, and all the difficult problems pointed to have been easily solved, thus promoting the development of navigation, military, tourism, and other undertakings.

The invention of the compass originated in the Warring States period, and in the late Northern Song Dynasty, the Chinese made the compass fish into a compass. The compass can be used in our military, navigation and daily life to identify the direction and determine the direction, which has promoted the development process of our country.

The record of the compass first appeared in the Warring States Period, which had a significant impact on the process of civilization in our country, promoted exchanges between various places, promoted exchanges between ancient countries and regions, and the development of navigation, as well as the opening of new shipping routes and the display of national culture.

The compass was invented during the Warring States period. It affects the status of China, and helps people's lives, can also help people identify the direction, can make people's lives more convenient and fast, and can help people who are lost to identify the direction in time.

During the Southern Song Dynasty, the compass invented in China was introduced to Europe by the Arabs. This technology was soon used in the nautical industry, leading to the opening of new shipping routes. The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on an axis, which is often used in navigation, geodesy, travel and military affairs.

The compass is the result of the understanding of magnetism by the ancient Chinese working people in long-term practice. The invention of the compass has played an immeasurable role in the development of human science and technology and civilization, and is indispensable even in the rapid development of modern times, and is still widely used in geodesy, travel and military affairs.

Modern people have made a variety of electronic compasses, smart phones generally have this software, electronic compass is also called digital compass, is a method of using the geomagnetic field to determine the North Pole, applied to mobile phones, in fact, it is an electronic compass, electronic compass is generally processed with magnetoresistive sensors and fluxgates.

The application of the compass in navigation has greatly promoted the great geographical discoveries and the sea**. The invention of the compass originated from the study of how to orient the problem in ancient China, and it also shows that the ancients attached great importance to the problem of how to orient, for which the compass is known as one of the four great inventions of ancient China. The ancient Chinese used the compass for military and navigational activities, and was also used for Kanyushu, and later introduced to Europe, playing an irreplaceable and important role in European navigation activities and geographical discoveries.

Among the inventions of nautical technology, the compass is also the single most important invention.

Because of the compass.

The invention and application can make outstanding contributions to the development and progress of world civilization, and can influence the whole world.

It has greatly promoted the development of the maritime industry, promoted the culture of the East and the West, promoted the economic exchanges, opened the country, promoted the living standards of the people, and had many benefits for the development of China.

The compass has many uses, which can affect the economic development of our country, and will also affect the development and production of history. It promoted the development of navigation technology, boosted the country's economy, and also boosted its military strength.

Mainly because the invention of this thing has a very important significance, and it also has a particularly great impact on our country, and it has also laid the foundation for follow-up research, and can be applied to many aspects, so it can have such a status.
