Can anyone recommend a style for writing theoretical physics papers? I'm just a first-year undergrad but I want to get used to writing papers in a style that is suited, or generally accepted, for theoretical physics papers by practicing on my class notes. Can someone also suggest an application that is useful for making mathematical symbols within the context of writing such papers? Some of my peers have suggested using the "equation" and "symbols" tools in microsoft word, but they seem inadequate. Thanks!
