\begin{abstract}
To date, very little has been written about the very important role
played by the magnetosphere during the conquest of the Western Hemisphere.
This paper tries to fill this gap by drawing on historical documents from the
years 1492 to 1888, the most vital years for this development. Almost no
conclusions are drawn as the influence appears to approach absolute zero.

\section{Introduction}\label{sec:intro}

%% Citations: \citep for parenthetical (Columbus, 1492), or
%%            \citet for in text, shown by Columbus (1492)

With the discovery of America \citep{colu92} a new continent was opened up.
However its full exploitation by Europeans and their offspring was not fully
complete until many centuries later, as reported by \citet{jame76}. During this
interval, known as the Winning of the West \citep{smit54}, a major role in
the development of the continent was played by the lowly revolver
\citep[e.g.][]{gree00}.  Recently, \citet{phil99} suggested that the
magnetosphere could have played an even more significant role. In order to
pursue this conjecture, the authors of this work have carried out a historical
survey and have found start\-ling\-ly little evidence for such a claim.

\section{The Discovery}
\label{sec:dis}

America was discovered by \citet{colu92}, as illustrated in Figure~\ref{fig:dis}.
Without the use of the compass, this would never have been possible. In fact,
this could be considered the most important (and only) contribution of the
geomagnetism to the development of the American continent.  A painting of
Christopher Columbus' departure is shown in
Plate~\ref{pla:columbus}.

on his first voyage in search of a quicker route to Asia. Here, Columbus
takes leave of Ferdinand~V and Isabella, the king and queen of Castile, who
sponsored his first expedition.

\end{plate*}

The subsequent taming of the West took place with considerable quantities of
lead, but since this non-mag\-ne\-tic, there are no geomagnetic variances
attributed to it.

\section{The Next Five Centuries}
\label{sec:next5}

In Section~\ref{sec:dis}, the discovery of America was described.
Here we will outline the subsequent history until the present. This is best
summarized in Table~\ref{tab:sum}.

\begin{planotable}{cll}
  \tablewidth{20pc}
\tablecaption
{\label{tab:sum}The History of America from Discovery to Present}
\tablehead{\colhead{Date} &amp; \colhead{Event} &amp; \colhead{Ref.}}
\startdata
1492 &amp; Discovery &amp; \citet{colu92}
  \nl
1776 &amp; Independence &amp; \citet{jame76}
  \nl
1954 &amp; Nothing much &amp; \citet{smit54}
  \nl
1999 &amp; Present &amp; \citet{phil99}
\end{planotable}

As can be seen from Table~\ref{tab:sum}, there is almost no mention of
geomagnetism or the magnetosphere at all. This sorry situation is discussed
further and explained away in Section~\ref{sec:end}.

\subsection{The Mathematics of Development}

The complete mathematical description is beyond the scope of this report, but
can be found in \citet{smit54}. The basic equation is
\begin{equation}
    z = \sqrt{x^2 + y^2} \label{eq:z} .
\end{equation}

In addition to Equation~\ref{eq:z}, we also have
\begin{eqnarray}
x &amp; = &amp; A \sin\theta \nonumber \\
y &amp; = &amp; A \cos\theta \nonumber \\
A &amp; = &amp; \int^\infty_0 dt\,f(t)  \label{eq:int}
.\end{eqnarray}
Equations~\ref{eq:z} and \ref{eq:int} together describe the entire time
development of the history of America. Again no geomagnetic term enters.

\subsubsection{Pseudo-mathematics.}
In addition to the true mathematics mentioned above, there are a number of
pseudo-mathematical theories, but these cannot be seriously considered by
reputable scientists.


\section{Conclusions}\label{sec:end}

Considering Figure~\ref{fig:dis} and Table~\ref{tab:sum} we see that the
influence of the geomagnetic and magnetospheric terms is negligible.
Furthermore, equations~\ref{eq:z} and \ref{eq:int} add no insight to the
problem. We must therefore conclude that \citet{phil99} incorrectly supposed
such a connection to exist.

In spite of this negative result, research will continue on this highly
interesting question. For if it were to prove correct, then the consequences
would be enormous to say the least.
