I'm interested in math, physics but also in the way it is taught and how one can learn efficiently.

Our society has to cope with an overwhelming amount of knowledge and I want to contribute in organizing, reformulating, simplifying and create new knowledge.

How to "box" an equation

Copied from here

$\sigma _{A}^{2}\sigma _{B}^{2}\geq \left|{\frac {1}{2}}\langle \{{\hat {A}},{\hat {B}}\}\rangle -\langle {\hat {A}}\rangle \langle {\hat {B}}\rangle \right|^{2}+\left|{\frac {1}{2i}}\langle [{\hat {A}},{\hat {B}}]\rangle \right|^{2}$,

Proof of blablabla

Simple link variance ; opérateurs auto-adjoint Indent, big parenthesis ${\big (}{\hat {A}}-\langle {\hat {A}}\rangle {\big )}$ Gives a number to the equation $\sigma _{A}^{2}\sigma _{B}^{2}=\langle f|f\rangle \langle g|g\rangle .$ (1) $\sigma _{A}^{2}\sigma _{B}^{2}\geq |\langle f|g\rangle |^{2}$. (2) $|z|^{2}={\Big (}{\text{Re}}(z){\Big )}^{2}+{\Big (}{\text{Im}}(z){\Big )}^{2}={\Big (}{\frac {z+z^{\ast }}{2}}{\Big )}^{2}+{\Big (}{\frac {z-z^{\ast }}{2i}}{\Big )}^{2}.$ (3) Call the reference of the first eq. (1) , third (3) END

First part makes an exponent, second fills in the info for the footnote

Then new exponent with a slash at the end

Example with links, the different elements appear in a fixed order, not the one in which one has written them.
