On the morning of the $8^{th}$ of August 1900 at the second International Congress of Mathematicians in Paris, David Hilbert 
gave a talk on `The Problems of Mathematics in the Future' (`Sur les probl\`emes futures des math\'ematiques').\cite{GGI}  He was invited to give a lecture and
gave 10 problems (from the 23 known Hilbert's problems) they were (1,2,6,8,12,13,16,19,21,22).\cite{GGI}  The entire 23 problems where published after the conference in \emph{Archiv der Mathematik und Physik}.
Hermann Weyl, one of Hilbert's students, later on stated that any one who solved one of the 23 problems
would be part of the honours class of mathematicians.\cite{GJ}

\textbf{Notes:}\\
This entry is under construction please feel free to add information as it editable by anyone who is a member.  Please reference what is added, thank you.
The idea, is maybe:
\begin{itemize} 
\item have a good introduction,
\item have a small discription of each problem, and as attached entry have more details on each problem separately,
\item have a good bibliography.
\item *AQFT = Algebraic, or Axiomatic Quantum Field Theory
\end{itemize}
Also I think we should not CC wikipedia.  This note can be removed once
the entry is complete.
