Fun with LaTeX

Here's Schroedinger's equation:

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

Here's Einstein's field equations in terms of the Ricci curvature tensor and Ricci scalar.

$latex R_{\mu \nu} - {1 \over 2}g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}$
