  We introduce here very briefly, through some selective choices of problems
and through the sample computer simulation programs (following the request of
the editor for this invited review in the Journal of Physics Through
Computation), the newly developed field of econophysics. Though related
attempts could be traced much earlier (see the Appendix), the formal researches
in econophysics started in 1995. We hope, the readers (students \& researchers)
can start themselves to enjoy the excitement, through the sample computer
programs given, and eventually can undertake researches in the frontier
problems, through the indicated survey literature provided.
