Who invented the compass Did the compass invent and who invented it?

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.

Who is the inventor of the compass is still inconclusive, there are relevant documents, according to legend, in 2700 BC China's Xuanyuan Yellow Emperor invented the compass, the Yellow Emperor used the compass, in the fog to discern the direction, defeated Chiyou. In ancient China, the compass was first used to determine directions during rituals, ceremonies, and military purposes.

The compass was called Sinan in ancient times, and the main component is 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 has three types of components, namely the sinan, the compass and the magnetic needle, all of which belong to Chinese inventions.

1. Who is the inventor of the compass is still inconclusive. According to authoritative historical records: the Yellow Emperor and Chiyou fought in the field of Zhuolu.

It is especially foggy, and the soldiers are fascinated. So he made a guide car to show the Quartet, and then captured Chi You and the emperor. Therefore, the compass is traditionally believed to have been invented by the Yellow Emperor.

2. It is also said that it is Luan's great invention. As early as the pre-Qin era, the Chinese working people had accumulated an understanding of magnetic phenomena, and when exploring iron ore, they often encountered magnetite, that is, trapped magnets. These findings have long been documented in several chapters of the Pipe:

"There is a magnet on the mountain, and there is gold and copper under it." There is a similar record in the "Classic of Mountains and Seas". The iron-absorbing properties of magnets were discovered very early, and the nine volumes of "Lü's Spring and Autumn" have mastery chapters:

Ci Zhao Tie, or lead to it. In the Western Han Dynasty, there was a monk named Luan Da, who used the characteristics of the magnet to make two chess pieces, by adjusting the mutual position of the polarity of the two chess pieces, sometimes the two chess pieces attracted each other, sometimes repelled each other. 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 history of the invention of the compass dates back toChinaAncient times. The earliest compasses were made of magnetic ore, orange orange and used to indicate the physical direction of the ground and the direction of the wind.

In hail Europe, the use of the compass began in the 13th century. The earliest compasses were made by Italian sailors and navigators who learned the techniques of making and using compasses from Eastern merchants.

It is believed that the earliestCompassIt may have been invented by a Chinese inventor, but the exact inventor is no longer known. Throughout history, many people have improved and developed the compass, thus making it an essential tool for modern navigation and navigation.

1, Zhang Heng. 2. The earliest guide tool used in China was Sinan during the Warring States Period. It looks like a spoon, but it's actually a big magnet spoon! Because the magnet is magnetic, one side points to the south and the other points to the north, and the handle of the spoon on the south always points to the south.

3. Zhang Heng used the mechanical principle and the transmission of gears to invent the guide car, which is a single-wheel two-wheeled vehicle equipped with a special differential gear device and a pointer.

4. It not only solves a difficult problem in the study of the history of science and technology in China, but also maintains the important position of the guide car in the history of science and technology, and further maintains the reputation of China's ancient and splendid civilization.
