\section{Motivation}
\subsection{The Basic Problem That We Studied}
\begin{frame}{Make Titles Informative. Use Uppercase Letters. Long Titles
are Split Automatically.}{Subtitles are optional.}
\begin{itemize}
\item
Use \texttt{itemize} a lot.
\item
Use very short sentences or short phrases.
\end{itemize}
\end{frame}
\begin{frame}{Make Titles Informative.}
You can create overlays\dots
\begin{itemize}
\item using the \texttt{pause} command:
\begin{itemize}
\item
First item.
\pause
\item
Second item.
\end{itemize}
\item
using overlay specifications:
\begin{itemize}
\item<3->
First item.
\item<4->
Second item.
\end{itemize}
\item
using the general \texttt{uncover} command:
\begin{itemize}
\uncover<5->{\item
First item.}
\uncover<6->{\item
Second item.}
\end{itemize}
\end{itemize}
\end{frame}
\subsection{Previous Work}
\begin{frame}[fragile]{An old algorithm}

\section{Our Results/Contribution}
\subsection{Main Results}
\begin{frame}{Make Titles Informative.}
\begin{example}
\begin{itemize}
\item 2 is prime (two divisors: 1 and 2).
\item 3 is prime (two divisors: 1 and 3).
\item 4 is not prime (\alert{three} divisors: 1, 2, and 4).
\end{itemize}
\end{example}
\end{frame}
\begin{frame}{Make Titles Informative.}
\begin{theorem}
There is no largest prime number and, in addition, $$\int_\Omega \nabla u \cdot \nabla v = - \int_\Omega u \Delta v + \int_{\partial\Omega} u v n$$
\end{theorem}
\begin{proof}
\begin{enumerate}
\item<1-> Suppose $p$ were the largest prime number.
\item<2-> Let $q$ be the product of the first $p$ numbers.
\item<3-> Then $q + 1$ is not divisible by any of them.
\item<1-> Thus $q + 1$ is also prime and greater than $p$.\qedhere
\end{enumerate}
\end{proof}
\uncover<4->{The proof used \textit{reductio ad absurdum}.}
