Key Equations

$$\hat{A}^\dagger = \hat{A}$$
$$P(\uparrow) = \frac{9}{25} = 0.36 = 36\%$$
$$|\psi\rangle \to \frac{\hat{P}_n|\psi\rangle}{||\hat{P}_n|\psi\rangle||}$$
$$\psi(x,t) = \sqrt{\frac{2}{L}}\sin\left(\frac{2\pi x}{L}\right)e^{-i\omega_2 t}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
