1Covariant derivative — In mathematics, the covariant derivative is a way of specifying a derivative along tangent vectors of a manifold. Alternatively, the covariant derivative is a way of introducing and working with a connection on a manifold by means of a… …

3Relativity priority dispute — Albert Einstein presented the theories of Special Relativity and General Relativity in groundbreaking publications that either contained no formal references to previous literature, or referred only to a small number of his predecessors for… …
4Erich Kretschmann — (1887 1973) was a German mathematician and Gymnasium (school) teacher.He obtained his D.Phil. at Berlin University in 1914 with his dissertation entitled Eine Theorie der Schwerkraft im Rahmen der ursprünglichen Einsteinschen Relativitätstheorie …
5Coordinate 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 …

7Hole argument — In general relativity, the hole argument is a paradox which much troubled Albert Einstein on the road to his famous field equation. It has recently been reinterpreted by philosophers as an argument against manifold substantialism , a doctrine… …
8Einstein-aether theory — In physics the Einstein æther theory , also called æ theory is a controversial generally covariant generalization of general relativity which describes a spacetime endowed with both a metric and a unit timelike vector field named the æther. In… …
9Scalar theories of gravitation — are field theories of gravitation in which the gravitational field is described using a scalar field, which is required to satisfy some field equation. Note: This article focuses on relativistic classical field theories of gravitation. The best… …
