The Compass: How a Small Navigational Instrument Changed the Face of the Earth

"The simplest form of navigation means to come back after you find your way." In most human history, maritime navigation moves along rivers, waterways, and the sea along the coast Including doing not to get lost. The compass changed this; seamen can boldly sail in the middle of the sea and know that if they fly to the west, what they have to do is to return to the east . The compass itself is a simple navigation device that contains magnetic elements aligned with the Earth's own poles so that the user can know the north-south and the east-west direction following it.

Compass was first invented in China in 300-200 BC, and since then it has been used as a navigation tool. Compass is a navigation device with a magnetized pointer pointing to the magnetic north of the earth. The earth is a magnet, and for this, it can interact with other magnets. All magnets have the North Pole and the South Pole, and the Earth is no exception. The geographical north latitude is 90 degrees, the longitude is 0 degrees, and the magnetic north pole is approximately 1,000 miles. For navigational purposes, the compass is most often used on maps, and maps magnetic and north lines above it for the most efficient use.

Compass is a navigation device that displays directions in a reference coordinate system that is stationary relative to the surface of the earth. The reference frame defines four basic directions (or points) north, south, east, and west. The intermediate direction is also defined. Usually, a chart called compass is marked on the compass, indicating the direction. When a compass is used, for example, the rose "N" points to the north because roses match the actual direction of the reference coordinate system. Usually, in addition to roses, angular markers are also displayed on the compass instead of roses sometimes. Since the north corresponds to zero degree and the angle increases clockwise, the east is 90 degrees, the south is 180 degrees and the west is 270 degrees. These numbers allow the compass to display the azimuth or azimuth. Another important navigation tool

Before a European navigator roamed the sea, the Chinese invented the compass, how was the navigational instrument invented? The compass was created during the Qin dynasty (255 BC - 206 BC), but it is not due to reasons you anticipated. Prior to being used for navigation, the compass was actually used to make predictions by fortune tellers on their board. Are you interested in using compass? The first compass is made of a spoon type magnet, which is a natural magnet that naturally forms the south. After that, the Chinese improved the first compass and made a magnetic needle compass for water in the 8th century.
