What is the ancestor of the compass and what are the origins of the compass?

Xuanyuan Yellow Emperor invented the guide car.

The compass was the earliest invention of our ancestors. Legend has it that about four or five thousand years ago, the Yellow Emperor and Chiyou fought, Chiyou would stir up wind and fog, although the Yellow Emperor was strong in martial arts, due to disorientation, the result was defeated by Chiyou. After the Yellow Emperor returned, Gao Pai summed up the lessons of this failure, and immediately organized people to carefully study and make tools to indicate the direction, and soon built a guide car.

In the second engagement, Chi You repeated his old tricks. The Yellow Emperor looked up to the sky and laughed, and ordered his subordinates to roll out the guide car. As a result, Chiyou was killed.

Since then, the clan of the Yellow Emperor has settled in the Yellow River Valley.

The reason why our ancestors were able to invent the compass car was to discover the characteristics of magnets, so as to invent "Sinan", which is the prototype of the compass. Sinan grinds the magnet into a spoon shape with a long handle, and puts it on a copper plate divided into 24 directions, the bottom of the spoon is very slippery, and the copper plate is very light, so that when the spoon rotates and stops, the key handle naturally points to the south. In the 11th century, our ancestors discovered in practice that after rubbing Qi Paixian on a natural magnet with a piece of iron, it can also generate magnetism, and it is relatively stable, so they made artificial magnets.

This significant discovery paved the way for the manufacture of more advanced compasses.

A compass is a simple instrument used to determine directions. The predecessor of the compass was Sinan, one of the four great inventions of ancient China. The main component is a magnetic needle mounted on a shaft that can be rotated freely.

The magnetic needle can remain in the tangential direction of the magnetic meridian under the action of the geomagnetic field. The north pole of the magnetic needle points to the north pole of geography, and the direction can be discerned using this performance. It is commonly used in navigation, geodesy, travel and military applications.

The name of the band also has the name of the band as well as the name of the movie.

Compass. It is the result of the long-term practice of the ancient Chinese working people to understand the magnetism of magnets. 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. In ancient China, the compass was first used for rituals, ceremonies, military affairs, divination and feng shui to determine directions.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on the shaft, the magnetic balance needle can rotate freely under the action of the natural geomagnetic field and remain in the direction of the tangent or barrage line of the magnetic meridian, the south pole of the magnetic needle points to the geographical south pole (magnetic field North Pole), and the direction can be identified by using this performance.

It is often used in navigation, geodesy, travel and military affairs. The invention of the compass that physically indicates the direction has three types of parts, namely Sinan and compass.

and magnetic needles, both of which are inventions in China. According to the "Ancient Mine Record".

The earliest record appeared in the area of Cishan during the Warring States period.

The compass is the result of the understanding of magnetism by the ancient Chinese working people in long-term practice. 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. In ancient China, the compass was first used for rituals, ceremonies, military affairs, divination and feng shui to determine directions.

?The ancient Chinese working people first discovered the attraction relationship between magnets and magnets, and invented the compass according to the directivity of magnets.

The working people of ancient China first came into contact with magnetite, and in the contact with magnets, they discovered the properties that magnets can guide, but the scientific theories at that time were not enough to explain the principle of this matter.

In the middle of the 11th century, the great Chinese scientist Shen Kuo was still surprised that the compass could be a guide, he wrote his "Mengxi Writings" to introduce the artificial magnetization method of the compass, as well as the production method of the compass, but why the compass can be guided, he did not have any reason to explain, in the book sighed: "The guide of the magnet ......Don't be excused! In the Song Dynasty, people used the doctrine of yin and yang and the five elements to explain the principle of the compass, believing that "what the compass refers to is where the yang energy is."

Although it is not easy to explain, it does not affect everyone's use, as early as the Warring States Period, people used the characteristics of the magnet to indicate the north and south to make a guide tool Sinan, and it was used until the eighth century. Later, there was a magnetic spoon, and after a long time, it was slowly improved, and more convenient magnetic needles and compasses appeared in the Tang Dynasty. Feng Shui said that "the earth is in the right position in the eight directions, and the road and the map are fixed, so the meridian is the territory, and the interior is in response to the reality of the place."

It refers to the compass.

The invention of the compass has played a great role in the development of China's navigation industry.

Before the Han Dynasty, the ancients wrote the magnet as "Cishi", which is an expression of love for the stone. In the Western Han Dynasty, there was a monk named Luan Da, who used the characteristics of the magnet to make two chess pieces, and by adjusting the mutual position of the polarity of the two chess pieces, the two chess pieces sometimes attracted and sometimes repulsed.

Luan Da called it "fighting chess". He dedicated this novelty to Emperor Wu of Han and demonstrated it on the spot. Emperor Wu of the Han Dynasty was amazed, and the dragon's heart was so happy that he actually named Luan Da as the "General of Wuli".

The earliest predecessor of the compass was a magnetic stone, and after the ancients discovered the properties of magnetic stones, they could use magnetic stones to point out directions.

Over time, improvements were made to the magnetic stone, and a twine or a paper line was added to probe the direction, so that the simplest compass was formed.

Later, people used the magnetic meridian and the magnetic needle guide, and hung them on the bamboo board on the bamboo needle to rent the Ling Song, the magnetic needle was held in the groove on the bamboo board, the magnetic needle pointed north and south, and Wang Liquid determined the direction.

It was not until modern times that people began to use electronic technology to use electronic compasses.

1.What is the predecessor of the compass.

The compass is one of the indispensable industrial rental pants for modern navigation, but its predecessor is actually a magnet compass car in ancient China. According to historical records, the Magnet Guide Car Yujian first appeared in the Han Dynasty (206 BC to 220 AD) and refers to a measuring tool made of magnetic needles made of magnets to indicate the direction.

2.The development history of the magnet guide car.

With the development of the times, the magnet guide car has been continuously improved and perfected. During the Tang Dynasty (618-907), people began to add scales to magnets to measure direction more precisely. During the Song Dynasty (960-1279), the south pointer appeared, which could be used to measure the southern direction.

By the Ming Dynasty (1368-1644), the magnet compass had evolved into a form similar to that of the modern compass.

3.The spread of the Chinese compass.

The Chinese magnet guide car was first transmitted to Arabia and then to Europe. In the Middle Ages in Europe, the compass was widely used in navigation and military affairs, and became one of the important technologies of that era.

4.Compass improvements.

After the compass was widely used in Europe, it was also continuously improved and refined. The earliest compass was suspended on a magnet by a magnetic needle, and later a compass hung horizontally appeared, which solved the problem that the magnetic needle was swung during navigation and affected navigation. Later, more precise navigation tools such as the liquid compass and the gyrocompass appeared in the compass.

5.The role of the compass in modern navigation.

As an important part of navigation tools, the compass is widely used in aviation, navigation, exploration and other fields. Modern compasses have been automated and intelligent through technological means, allowing them to indicate direction more precisely.

6.Conclusion.

Although the compass's predecessor, the magnet compass, was an ancient measuring tool, its development and improvement laid the foundation for the compass to become an important tool for modern navigation. The continuous evolution and improvement of the compass has made it more accurate and safe for people to explore the unknown and travel and sail.

The predecessor of Compass was Sinan.

Ancient Chinese people generally distinguished the direction by looking at the North Star, but in order to cope with the starless night, the compass was invented. The predecessor of the compass is Sinan, and Sinan is shaped like a big spoon, which is made according to the Big Dipper, because if you find the Big Dipper, you can find the North Star. Sinan's spoon handle is indeed pointing to the south, so the compass invented later, because of its use and function is the same as Sinan, it is also called "compass" along Sinan, because you can find "south" if you know "north".

The compass is one of the four great inventions of ancient China, and friends who have used the compass know that the current compass pointer is painted red and blue. Usually we look at the red arrow, but the red arrow does not refer to the south, but to the north of the earth.

The importance of the compass

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 the ancient people were oriented in China, and it also showed that the ancients attached great importance to the problem of orientation such as the rubber school, for which the compass was 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.
