\begin{block}{Block Title}
\begin{itemize}
\item This is a block
\item You may use itemize to handle the bullet point
\item Be aware of the length
\end{itemize}
Some math formula:
\begin{equation*}
a+b=c
\end{equation*}
\end{block}
\end{frame}
\begin{frame}{Math Formula}
You may also write anything without using the block:
\begin{equation*}
a+b=c
\end{equation*}
Add a bibliography wherever you need it~\cite{kopka2003guide}, or as \citet{kopka2003guide} suggests.
