I want to highlight a certain part of a formula from one slide to the next.

I'm looking for something similar to

Non bold on slide 1 \textbf<2>{this is bold on slide 2}

just in math mode.

I guess you are looking for something like the \alt. In some cases you might even have the desire to have something maybe gray just to this special moment, and then it only needs to be there. Maybe the command \temporal can be helping:

\documentclass{beamer}
\usepackage{amsfonts}
\begin{document}
\begin{frame}
Non bold on slide 1 \textbf<2>{this is bold on slide 2}

i am the \alt<1,3>{standard}{alternative}:
$\alt<1,3>{a}{\mathbf{a}}$

\temporal<2>{before: $a$}{right now: $\mathbf{a}$}{after: $a$}

pdfpage: \thepage
\end{frame}
\end{document}

    @bonanza I added the temporal command, maybe you find that useful, too. – Johannes_B Feb 6 '14 at 15:19
