This unit begins by extending Special Relativity concepts into accelerating frames, and connecting it to Maxwell's Equations. Then a slightly more mathematical treatment of curvature is presented, leading up to the Einstein Field Equations. Applications of the Field Equations to weak fields and predictions for gravitational waves conclude the unit.

The text and 10 homework problems are included within the PDF file. Below is a background supplement with additional mathematical background.
