Hey there folks, Within my AP Calc-Physics class everyone is beginning an independent study of (semi)-modern physics, and I, in my ignorance, chose General Relativity because I felt it would be interesting to learn all of this about time dilation and etc. I have till next Thursday to finish a research paper and prepare a lesson plan so I can teach General Relativity (to an extent) to the rest of the class on that day. I have finished the AP Calculus BC course and AP Calc-Physics course, so that is the prior mathmatical knowledge I have available to me. Unfortunately, after scanning through several canonical, jargon-filled books, I seem to be woefully unprepared for a mathmatical understanding of General Relativity. I generally latch onto mathmatical concepts very easily, but even trying to understand what terms I need to understand, to understand General Relativity is very difficult as I cannot seem to find an explanation that uses the same terms I'm trying to understand (If you understand what I'm saying .) I come here in hopes that I can attain some aid in this matter from those of you who already understand the material. I don't need a very in-depth understanding of General Relativity, as I only have one class period to explain the subject to my peers but I'm hoping to get into something "cool" such as time dilation near a body of mass or other such intriguing phenomena of general relativity. If I can get any help whatsoever, I would very much appreciate it. Thanks.
