Compass
Compass- is a navigational instrument that shows directions in a frame of reference that is stationary relative to the surface of the earth. The frame of reference defines the four cardinal directions (or points) – north, south, east, and west. Intermediate directions are also defined. Usually, a diagram called a compass rose, which shows the directions (with their names usually abbreviated to initials), is marked on the compass. When the compass is in use, the rose is aligned with the real directions in the frame of reference, so, for example, the "N" mark on the rose really points to the north. Frequently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.
The magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since about 206 BC).[1][2][3] The compass was used in Song Dynasty China by the military for navigational orienteering by 1040-1044,[4][5][6] and was used for maritime navigation by 1111 to 1117.[7] The use of a compass is recorded in Western Europe between 1187 and 1202,[8][9][10] and in Persia in 1232.[11] The dry compass was invented in Europe around 1300.[12] This was supplanted in the early 20th century by the liquid-filled magnetic
