Are There Pictorial Examples of Covariant and Contravariant Vectors
We present pictorial means of distinguishing contravariant vectors (or simply vectors) from covariant vectors (or linear forms).
Derivation of gravitational waves in Einstein, Brans-Dicke and Rosen theories of gravity.
Mathematical derivation of gravitational waves to quadrupole order in the Brans-Dicke scalar-tensor and Rosen bi-metric theories of gravity.
