What impact did China's compass navigation technology have on which major events in Europe?

Compass (compass) is a tool for feng shui detection, and it is also a common operating tool for managing style. It is mainly composed of a magnetic needle and a series of concentric circles located in the center of the disk, and each circle represents the ancient people's understanding of a certain level in the universe system in China. The coordination of the orientation and spacing of each layer on the compass also implies the law of "magnetic field"

Engels said in the book Machine, Natural Forces and the Application of Science: "Compass opened the world market and established a colony." This invention of ancient people in China was first used for navigation, which really promoted the emergence and development of capitalism. Magnetic needles are used for navigation, making three quarters of the earth's sea area a thoroughfare.

From 65438 to the 5th century, Columbus crossed the Atlantic Ocean and reached the American continent. /kloc-At the beginning of the 6th century, the success of Magellan's fleet sailing around the world could not be separated from the application of magnetic needles. However, when and how the magnetic needle was introduced into Europe has been debated by international scholars for hundreds of years. Engels made a scientific conclusion in Dialectics of Nature. He pointed out that "the magnetic needle was" passed from China to Europeans "around" 1 180 ".
