Physical and Geometric Interpretations of the Riemann Tensor, Ricci Tensor, and Scalar Curvature
arXiv:gr-qc/0401099
Abstract
Various interpretations of the Riemann Curvature Tensor, Ricci Tensor, and Scalar Curvature are described. Also, the physical meanings of the Einstein Tensor and Einstein's Equations are discussed. Finally a derivation of Newtonian Gravity from Einstein's Equations is given.
