This is some silly repo to see if I can get emoji and mathjax to play nicely together

$\frac{1}{\sqrt{2}}\vert🐱\rangle + \frac{1}{\sqrt{2}}\vert💀\rangle$

$\frac{1}{\sqrt{2}}\vert😀\rangle + \frac{1}{\sqrt{2}}\vert😢\rangle$

$\frac{e^{2}}{mc^{2}}\sqrt{-1}\frac{PV}{nR}$

$\displaystyle\sum_{n=1} ^{\infty} \frac{🍪^{n}}{n!} = e^{🍪}$

$우^{영^{우}}$

$\int_{甲}^{乙}\sqrt{龍},dx$

$\langle カ \vert か \rangle \times \langle き \vert キ \rangle $
