I updated my notes on General Relativity (GR) and Gravity, building on the Central Lectures given by Dr. Frederic P. Schuller for the WE Heraeus International Winter School on Gravity and Light. There are also Python scripts for using Sage Manifolds 0.7 package for Sage Math that helps with calculations. In particular, Schwarzschild.sage answers Tutorial Sheet 13 for the International Winter School and implements the Schwarzschild metric and Reissner-Nørdström metric. That’s on my github and I’ll leave it there.
Google Drive changes all the time so I’ll put Gravity_Notes.pdf and the LaTeX file Gravity_Notes.tex on Google Drive and wordpress.com

Thanks, keep watching those YouTube videos from the WE Heraeus International Winter School on Gravity and Light, the best video lectures on General Relativity, ever, and I’ll keep trying to put out notes and code (I’m trying to get a job with SpaceX and in aerospace while trying to keep up some basic research in physics).
