Very good, Incog. Just a suggestion if it could be done Can you seperate the posts in groups, by year Not on every single one, but something like. Compass Wikipedia. This article is about the direction finding instrument used in navigation. For other uses, see Compass disambiguation. A simple dry magnetic portable compass. A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions or points.

Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials. When the compass is used, the rose can be aligned with the corresponding geographic directions for example, the N mark on the rose really points northward. Compasses often display markings for angles in degrees in addition to or sometimes instead of the rose. North corresponds to 0, and the angles increase clockwise, so east is 9. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese. Han Dynasty since c. BC,12 and later adopted for navigation by the Song Dynasty Chinese during the 1. Storks Movie Out. The first usage of a compass recorded in Western Europe and the Islamic world occurred around the early 1. Magnetic compasseditThe magnetic compass is the most familiar compass type. It functions as a pointer to magnetic north, the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earths magnetic field. The magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earths North magnetic pole, and pulling the other toward the Earths South magnetic pole. The needle is mounted on a low friction pivot point, in better compasses a jewel bearing, so it can turn easily. When the compass is held level, the needle turns until, after a few seconds to allow oscillations to die out, it settles into its equilibrium orientation. In navigation, directions on maps are usually expressed with reference to geographical or true north, the direction toward the Geographical North Pole, the rotation axis of the Earth. Depending on where the compass is located on the surface of the Earth the angle between true north and magnetic north, called magnetic declination can vary widely with geographic location. The local magnetic declination is given on most maps, to allow the map to be oriented with a compass parallel to true north. The location of the Earths magnetic poles slowly change with time, which is referred to as geomagnetic secular variation. The effect of this means a map with the latest declination information should be used. Some magnetic compasses include means to manually compensate for the magnetic declination, so that the compass shows true directions. HistoryeditThe first compasses in ancient Han dynasty China were made of lodestone, a naturally magnetized ore of iron. The compass was later used for navigation during the Song Dynasty of the 1. Later compasses were made of iron needles, magnetized by striking them with a lodestone. Dry compasses began to appear around 1. Medieval Europe and the Islamic world. This was supplanted in the early 2. Modern compassesedit. A liquid filled protractor or orienteering compass with lanyard. Magnetic compasseditModern compasses usually use a magnetized needle or dial inside a capsule completely filled with a liquid lamp oil, mineral oil, white spirits, purified kerosene, or ethyl alcohol is common. While older designs commonly incorporated a flexible rubber diaphragm or airspace inside the capsule to allow for volume changes caused by temperature or altitude, some modern liquid compasses utilize smaller housings andor flexible capsule materials to accomplish the same result. The liquid inside the capsule serves to damp the movement of the needle, reducing oscillation time and increasing stability. Key points on the compass, including the north end of the needle are often marked with phosphorescent, photoluminescent, or self luminous materials1. As the compass fill liquid is noncompressible under pressure, many ordinary liquid filled compasses will operate accurately underwater to considerable depths. Many modern compasses incorporate a baseplate and protractor tool, and are referred to variously as orienteering, baseplate, map compass or protractor designs. This type of compass uses a separate magnetized needle inside a rotating capsule, an orienting box or gate for aligning the needle with magnetic north, a transparent base containing map orienting lines, and a bezel outer dial marked in degrees or other units of angular measurement. The capsule is mounted in a transparent baseplate containing a direction of travel DOT indicator for use in taking bearings directly from a map. Cammenga air filled lensatic compass. Other features found on modern orienteering compasses are map and romer scales for measuring distances and plotting positions on maps, luminous markings on the face or bezels, various sighting mechanisms mirror, prism, etc. The sport of orienteering has also resulted in the development of models with extremely fast settling and stable needles utilizing rare earth magnets for optimal use with a topographic map, a land navigation technique known as terrain association. The military forces of a few nations, notably the United States Army, continue to issue field compasses with magnetized compass dials or cards instead of needles. A magnetic card compass is usually equipped with an optical, lensatic, or prismatic sight, which allows the user to read the bearing or azimuth off the compass card while simultaneously aligning the compass with the objective see photo. Magnetic card compass designs normally require a separate protractor tool in order to take bearings directly from a map. The U. S. M 1. 95. A deep well design is used to allow the compass to be used globally with a card tilt of up to 8 degrees without impairing accuracy. As induction forces provide less damping than fluid filled designs, a needle lock is fitted to the compass to reduce wear, operated by the folding action of the rear sightlens holder. The use of air filled induction compasses has declined over the years, as they may become inoperative or inaccurate in freezing temperatures or extremely humid environments due to condensation or water ingress. Some military compasses, like the U. S. M 1. 95. 0 Cammenga 3. H military lensatic compass, the Silva 4b Militaire, and the Suunto M 5. NT contain the radioactive material tritium 1. H3 and a combination of phosphors. The U. S. M 1. 95. Ci millicuries of tritium. The purpose of the tritium and phosphors is to provide illumination for the compass, via radioluminescenttritium illumination, which does not require the compass to be recharged by sunlight or artificial light. However, tritium has a half life of only about 1. Ci of tritium when new will contain only 6. Consequently, the illumination of the display will fade. Mariners compasses can have two or more magnets permanently attached to a compass card, which moves freely on a pivot. A lubber line, which can be a marking on the compass bowl or a small fixed needle, indicates the ships heading on the compass card. Traditionally the card is divided into thirty two points known as rhumbs, although modern compasses are marked in degrees rather than cardinal points. The glass covered box or bowl contains a suspended gimbal within a binnacle. This preserves the horizontal position.
