What is General Relativity? Lesson 69: The Einstein Equation

Having done so much work with the Einstein tensor, the interpretation of the Einstein equation is almost anti-climatic! The hard part is finding the Newtonian limit in order to understand the constant of proportionality between the curvature of spacetime and the energy density of spacetime.

This lecture begins with an interpretation of the Einstein equaiton and then lays the foundation for investigating its Newtonian limit. The next lecture calculates the Newtonian limit of the Einstein Equation and discovers the origin of the 8\pi factor.
