 \begin{frame}{Why presentation with LaTeX?}
   Pros:
 
   \vspace{0.2cm}
   \begin{itemize}
     \item Easy to include formulas and theorems
     \item Portability: \texttt{pdf} = \textbf{portable} document format
     \item Very fast to get ``good enough'' results (subjective)
   \end{itemize}
 
   \vspace{0.5cm}
   Cons:
 
   \vspace{0.2cm}
   \begin{itemize}
     \item Advanced animations not possible with pdf
     \item Lack of other presentation-specific features
   \end{itemize}
 \end{frame}
 
 \begin{frame}{Structure of a Beamer document}

 \begin{frame}{The \texttt{frame} environment}
   \texttt{\bs begin\{frame\}[options]\{Title\} \,\dots\, \bs end\{frame\}}
 
   \vspace{0.5cm}
   Useful options:
   \begin{itemize}
     \item \texttt{plain}: no bars on bottom or side
     \item \texttt{shrink}: content is shrunk to fit in the slide
     \item \texttt{fragile}: when you have \texttt{tikzpicture},
           \texttt{listings} or similar 
   \end{itemize}
 \end{frame}
 
 \begin{frame}{Basic animations}
   \begin{itemize}
     \item \texttt{\bs pause} for a simple break
 
     \vspace{0.3cm}
     \item \texttt{\bs only<start-(end)>\{\emph{stuff}\}} to show
           \emph{\texttt{stuff}} only on some slides
           
           Shortcut for lists: \texttt{\bs item<\dots>} or
           \texttt{\bs begin\{itemize\}[<+->]}
 
     \vspace{0.3cm}
     \item Optional:
           \texttt{\bs setbeamercovered\{transparent\}} (see end of slides)
 
     \vspace{0.3cm}
     \item \texttt{\bs uncover<\dots>} does not take space when invisible
   \end{itemize}
 \end{frame}
 
 \begin{frame}{Theorems and lists}
   \begin{theorem} This is a Theorem \end{theorem}
   \begin{proof} With proof \end{proof}
   
   \begin{itemize}
     \item \texttt{theorem}, \texttt{proof} and \texttt{definition} already
           included with beamer.
     \item Define new theorems as usual (they get a box automatically)
   \end{itemize}

     \texttt{\qquad(stuff)}
 
     \texttt{\qquad\bs column\{\emph{width}\}}
 
     \texttt{\qquad(more stuff)}
 
     \texttt{\qquad\qquad\vdots}
 
     \texttt{\bs end\{columns\}}
   \column{0.7\textwidth}
     \begin{itemize}
       \item \texttt{\emph{width}} is a length (example:
             \texttt{0.7\bs textwidth})
       \item Example: picture on the left, text on the right
       \item Not specific to Beamer
       \item Alternative: \texttt{tabular}
     \end{itemize}
   \end{columns}
 
 \end{frame}
 
 \begin{frame}{Some advice}
   \begin{itemize}
     \item Do not prepare too many slides (1-2 minutes per slide)
     \item Do not write too much in each slide (split if necessary)
     \item Pictures and \texttt{itemize}s are great, sentences are not
     \item Animations are ok (but are they worth the effort?)
   \end{itemize}
 \end{frame}
 
 \begin{frame}{Examples}
   Three examples will follow:
   \begin{itemize}
     \item A horrible slide
     \item A better slide with the same content
     \item A better better slide that took a little more time to write
   \end{itemize}
 \end{frame}
 
 \begin{frame}{Diophantine equations (bad)}
   Diophantine equations are a very old problem, dating back to Diophantus of
   Alexandria (III century A.D.).
 
   Despite this, they are still today a very hard problem, and there is
   no general method or algorithm to solve them.
 
   A notable example is \emph{Fermat's Last Theorem}, stated for the first time
   in 1637 but proved to be true only in 1995, after more than 350 years!

 \begin{frame}{Diophantine Equations (better)}

     \item Very old problem
     
     \vspace{0.3cm}
     \item Very simple formulation, but very hard to solve!
     
     \vspace{0.3cm}
     \item ``Fermat's Last Theorem'': stated in 1637 - proved in 1995
