General Relativity

This week's short lecture is just a brief overview of General Relativity. You're going to have to spend some serious time in the text to get to the nitty-gritties. 

The Achieve homework assignment that goes with this lecture is based on chapter 15, sections 1,2, and 3.

Take your time and READ! (R.T.F.Q.!)

Remember, the purpose of these topics on Relativity (both Special and General) is get you up to speed on the true nature of space and time,  or as we in cosmology say, "spacetime."
