Obsidian for mathematics

[GLight]

For equation numbering, a workaround is provided here:

Referencing Equations

This is really interesting! Thank you! I slightly upgrade it: using $\eqref{eq1}$ so that the equation label can be refereed inline. $$e=mc^2 \tag{1} \label{eq1}$$ Einstein provides $\eqref{eq1}$ in his paper.

For Propositions, etc, I prefer using quote in Obsidian to give them different look, combined with the bold font.

Observation 1: quote will add a frame around the text and make them looks special and different from the other text.

Based on Observation 1, I propose to use quote to mark the important block of text.
