(I'll prefix by apologizing if this is the wrong section to post in) I am wondering if anyone knows a good book on the topic of General/Special Relativity. I have tried searching for one but all the ones I have found are either too basic with no math (or I guess physics) at all, or literal textbooks. I have already read A Brief History of Time (S. Hawking) and Black Holes and Time Warps (K. Thorne) and neither really gave me the level of depth I was hoping for. I am comfortable with equations and the math behind it but not quite to the level where I can just learn from a textbook. Thank you.
