Beamer, pause, and space after equations

"\pause" is a very commonly used command in Beamer presentations to prevent displaying all of the slide at once.

In general, it works quite well as this minimal example shows:

Here the pause command was used between the equation and the line "This is the eigenvalue problem".

No problem, right (no pun intended)!

Using an itemize environment can cause some funny extra-space to be inserted between an equation and the next line:

Notice the extra space between the equation and the next item.

A relatively easy fix is to insert a blank line between the equation and the next item.

The code used to generate the three cases is below.

Beamer Howto: Scale Equations to Fit a Slide

A quick and dirty way to scale equations, especially equations with matrices spelled out, so that they fit on a line uses the commonly used graphicx package.

In the preamble say:

\newcommand\scalemath[2]{\scalebox{#1}{\mbox{\ensuremath{\displaystyle #2}}}}

And when you need to use it say something like $\scalemath{0.7}{rest of the equation}$
