 <content>This is a contributed topic on \emph{computational physics}.

\begin{definition}
\emph{Computational Physics} is broadly defined as the application 
of \PMlinkname{computer programming}{TopicOnComputerProgramming}, as well as of other computational means, such as: algebraic, topological, categorical, logical (including quantum logic, many-valued logics, automata theory), and so on, to obtain physically relevant results --that are often numerical.
\end{definition}


 This term is often employed in the more restricted, practical sense of applying computers to obtain numerical solutions to physics problems, or as an illustration to physical processes, phenomena or theories. At the top end of computing resources, supercomputers are beginning to be very widely employed
in physics for a variety of reasons, including relatively inexpensive simulations of very important physics problems that cannot be solved at present by any other means. Other, several contributed examples will be considered next in this topic, and are also more precisely defined in the following bibliography (available in part for download from the book and expositions/paper sections of PlanetPhysics.org). 

\begin{itemize}
\item Computational fluid dynamics-in rheology; $(PAC:02.70.-c)$
\item Computational methods in classical mechanics ($45.10.-bxx$; see also $02.70.-c$)
\item Computational techniques in mathematical methods in physics
\item Programming languages (Fortran, Basic/TurboBasic/AppleBasic, Algol, Pascal, $C / C^{++}$), programs (Mathematica, Maple, Systat) and OS systems ($UNIX$, $Linux$, Windows, $OS X$) employed in Computational Physics  
\item Concepts: UTM, quantum automata concepts 
\item Quantum Computations in: QCD, QFT, AQFT, QED, LQED, LQFT, LQG, quantum molecular dynamics (QMD) and quantum chemistry (QC)
\item F
\item G
\item H
\item K
