What is General Relativity? Lesson 53: Scalar Curvature Part 2 - The Tetrad Formalism

In this lecture we introduce the tetrad formalism. This is a pre-requisite, in my opinion, to the study of Riemann Normal Coordinates, although RNC are not always introduced with the tetrad formalism in place. Regardless, the tetrad formal is a critical concept in intermediate GR, so we might as well introduce the idea here.
