$\displaystyle R^{\mu\nu}-\frac{1}{2}g^{\mu\nu}R = \frac{8\pi \kappa}{c^{2}}T_{\mu\nu}$ $R^{μ ν} - \frac{1}{2} g^{μ ν} R = \frac{8 π κ}{c^{2}} T_{μ ν}$

$\displaystyle \hat{\mit H}\Psi = E\Psi$ $\hat{H} Ψ = E Ψ$

$\displaystyle \mathcal{S} = \int_{t_1}^{t_2} Ldt$ $S = \int_{t_{1}}^{t_{2}} L d t$

$\displaystyle \dfrac{\partial\mathcal{L}}{\partial q_i} - \dfrac{d}{dt}\dfrac{\partial\mathcal{L}}{\partial\dot{q_i}} = 0$ $\frac{\partial L}{\partial q_{i}} - \frac{d}{d t} \frac{\partial L}{\partial \dot{q_{i}}} = 0$

$\displaystyle (i\hbar\gamma^\mu\partial_\mu-mc)\psi = 0$ $(i ℏ γ^{μ} \partial_{μ} - m c) ψ = 0$
