\section{Main elements of Beamer slides}

\subsection{Math formulas}

\begin{frame}
  \frametitle{Text, fonts, and formulas}
Here is some text on my slide. 

If I want, I can set up some formulas:
$$
E = mc^2.
$$

This is \alert{important}:
\[
e = \lim_{n \to \infty} {\left( 1 + \frac{1}{n} \right)}^n
\]

You can also use \textbf{boldface} and \textit{italics}.

%%% If you are including verbatim text, make the frame fragile
\begin{frame}[fragile]
\frametitle{Including text verbatim}
Typically you include program code verbatim:
\begin{verbatim}
(defn get-match-name [fname]
  "extract a function name from a qualified name"
  (let [m (nth (re-matches #"(.*)\$(.*)" fname) 2)
        matched (if m m (nth (re-matches #"(.*)/(.*)" 
            fname) 2))]
    (if matched
      (check-if-anonymous-function 
           (lookup-funct-name matched))
      fname)))
\end{verbatim}
\end{frame}
