What I am looking for is a link or "cheat sheet" that will give me an explaination of the symbols that are used in Physics Formulas. I have a basic understanding of some of the symbols but there are some that I do not understand. I have read several of Prof. Hawkings and Prof. Einsteins papers and I am wanting to get a better understanding of what I have read. Could I get some help in this matter? Thanks to all that respond!
