Most papers are made in TEX or LaTEX. These formats separate display from data in such a way that they can be quickly formatted to a variety of page size, margins, text size, et al with minimal effort. It’s basically an open standard typesetting format. You can create and edit TEX in any text editor and run it through a program to prepare it for print or viewing. Nothing else can handle math formulas, tables, charts, etc with the same elegance. If you’ve ever struggled to write a math paper in Microsoft word, seriously question why your professor hasn’t already forced you to learn about LaTEX.
