How I'm able to take notes in mathematics lectures using LaTeX and Vim (opens in new tab)

Do you talk about math lectures? Because during my university time I seldom met people, who understood a math lecture during that math lecture. Especially in advanced topics like category theory, algebraic theory, fractal geometry etc. Usually people understood topics and concepts for the first time long after the lectures, often not until after a second exposure in the next course. Also, in many courses you had to take notes, because the lecturer would use custom symbols and definitions. So I agree, taking notes can be distracting, but in most cases it should help your understanding, especially if you lack preliminaries.

> But how about creating the LaTex notes after class as a method to help retain the information?

I recommend solving exercises instead (with pen and paper), and creating flash cards for memorizing.

Golden rule: Use LaTeX only, if you really need to publish something for a wider audience. It's relevant for your thesis, research papers and math books. For everything else, LaTeX is nothing but a huge time sink. Even if you communicate math via email, try to avoid sending PDFs. Use common LaTeX syntax in your email plain text instead.

Don't abuse LaTeX for procrastination.
