I know someone posted something similar before. However, that person definitely has taken some advanced math classes before. I am a biology/pharmacy major and I want to teach myself relativity. The most difficult math and physic classes I have taken are calculus 3 and physical chemistry respectively. I am currently reading "Linear algebra and its applications by David C lay" Can someone make up a list of books I need to read in order to understand relativity? How long will it take to read and understand all the prerequisites?
