In reading journal articles (in physics), I often come across recurring equations in the Introduction sections. Sometimes they don't mention its name. For example, I come across
$\begin{eqnarray*} E\Psi &=& {\skew{6}{\hat}{H}}\Psi\\ i\hbar\frac{\partial}{\partial t} &=& {\skew{6}{\hat}{H}}\Psi\\ \end{eqnarray*}$
Yes, that's the Schrödinger equation (not that I actually understand it, just got it from Wikipedia). But what if I didn't know what it is? Is there some place I can type in the equation, then I'll know what its name is? Then from there, I'll know where to start looking for more information.
