I want to write a research paper on general relativity or mathematical physics. I am a college freshman (will become sophomore after this summer) belonging to an engineering major. In this summer break, I have managed to learn about tensors. Currently, I am following the Respected Professor Leonard Susskind's lectures on General Relativity via youtube. Before the end of my holidays, I plan to write a simple research paper on mathematical physics or general relativity. Regarding my goals, i want to ask a few simple questions: 1. How should i approach? Are there any initial tips you would like to recommend? 2. How should I choose a topic for my paper, especially when i want it to be simple, but have a choice of complex subjects to write on? Thanks.
