This is the way to insert a figure or simply
leave some white space for a figure that is to be
pasted in later, like a photo or a hand-drawn sketch. As seen in
Figure~\ref{fig:picture},

\section{Experimental procedure}
The experimental procedure described in the lab manual~\cite[pp.~13--17]{manual}
was followed exactly. We found that the following changes were necessary to
make the circuit work:
\begin{itemize}
\item
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx.
\item
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx.
The modified circuit diagram is presented in Figure~\ref{fig:circuit}.

saved as a PostScript file.}

\section{Results}
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx as shown in Equation~\ref{eq:power}
\begin{equation}
P = I V = I^2 R = { {V^2} \over R } \quad ,
\label{eq:power}
\end{equation}
where $V$ is voltage~(V), $I$ is current~(A), and
xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx.
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
xxx xxxxx xxxxx xxx xxxx xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx
Multi--line equations are also possible (see Equation~\ref{eq:multi})
\begin{eqnarray}
P & = & I V \nonumber \\
& = & I^2 R
\label{eq:multi}
\end{eqnarray}
where some lines may be left unnumbered.

The summary of the experimental results is presented in Table~\ref{tab:summary}
\begin{table}[htp]

not at bottom as for figures.}

xxx xxxxx xxxxx xxx xxxx data points with error bars, and the
curve fitted to the data using Equation~\ref{eq:power} are shown
in Figure~\ref{fig:plot}
\begin{figure}[htp]

\end{figure}
and the text after the figure. The raw data is presented in Appendix~\ref{app:data}.
xxxx xxxxx xxxxx xxxx xxxxx xxxx xxxxxxxxx.
The graph of Figure~\ref{fig:plot} was generated using {\tt physica}
(see the macro file shown in
Appendix~\ref{app:macro}). The data points are shown as well
as the curve representing the least--squares fit to the data.
{\tt physica} reports the value of the slope of the graph to be
$-21452\pm801$, which is equal to $h\nu/k$. Thus from
the graph one can determine everything.
\subsection{Sample Calculation for Power}
The following calculation shows how the power was obtained. Note that this value is
proportional to power, but it not the value for power itself.
\begin{eqnarray*}
P & \propto & V^2 \\
& \propto & (0.0017V-0.0004V)^2 \\
& \propto & 1.69\times10^{-6} V^2
\end{eqnarray*}
