• Astronomical coordinate systems — are coordinate systems used in astronomy to describe the location of objects in the sky and in the universe. The most commonly occurring such systems are coordinate systems on the celestial sphere, but extragalactic coordinates systems are also… …   Wikipedia

• Coordinate system — For geographical coordinates on Wikipedia, see Wikipedia:WikiProject Geographical coordinates. In geometry, a coordinate system is a system which uses one or more numbers, or coordinates, to uniquely determine the position of a point or other… …   Wikipedia

• Coordinate time — In the theory of relativity, it is convenient to express results in terms of a spacetime coordinate system relative to an implied observer. In many (but not all) coordinate systems, an event is specified by one time coordinate and three spatial… …   Wikipedia

• Coordinate surface — The coordinate surfaces of a three dimensional coordinate system are the surfaces on which a particular coordinate of the system is constant, while the coordinate lines are the curves along which two of the coordinates of the system are constant …   Wikipedia

• Coordinate-free — A coordinate free, or component free, treatment of a scientific theory or mathematical topic develops its ideas without reference to any particular coordinate system. Coordinate free treatments generally allow for simpler systems of equations,… …   Wikipedia

• Coordinate conditions — In general relativity, the laws of physics can be expressed in a generally covariant form. In other words, the real world does not care about our coordinate systems. However, it is often useful to fix upon a particular coordinate system, in order …   Wikipedia
