\section*{Introduction}
I saw an insect walking along the hallway in 
Building 76 this morning.
``How fast is it moving?'' I wondered.
In this experiment, the speed of the insect
will be determined using simple instruments.


\section{Observations}
I marked the hallway with pieces of tape,
using a ruler to place each piece 5 cm from 
the previous one.
Each time the insect's forelegs reached
a piece of tape,
I noted the time with a hand-operated stopwatch.

\begin{tabular}{ | r | r | }
 \multicolumn{2}{c}{Progress of the insect} \\
 \hline
  Position (cm)  &  Time (sec)    \\
 \hline
  0   &  0.0  \\
  5   &  3.1  \\
  10  &  5.9  \\
  15  &  8.6  \\
  20  &  12.2 \\
 \hline
\end{tabular}


\section{Analysis}

A linear fit to the measurements
yields

\begin{equation}
x = (0.598 \pm 0.05 {\rm \ cm/s}) t - 0.02 {\rm \ cm} 
\end{equation}

where $x$ is the position of the insect
and $t$ the time.

\section{Conclusion}

This insect doesn't walk as fast as a human.
