Coordinate Conditions

This article briefly describe on Coordinate Conditions, in terms of relativity physics. The Einstein field equations do not distinctively determine the metric, even if one recognizes the particular metric tensor equals all over at a first time. Generally relativity, the laws of physics can be portrayed in a covariant form generally. Simply, the description of the world as distributed by the laws of physics will not rely selection of coordinate systems. However, it is useful to fix after a particular coordinate system often, in order to resolve genuine problems or make genuine predictions.
