  abstract={Galactic structure traditionally had been the domain of Newtonian dynamics.
It had been determined that the overall mass distribution of
galaxies and their motions were determined by the gravitational forces
acting on them. Galactic structure required that there be long-range
interaction such as gravity in order to create such structures. Another
model was introduced for creating spiral structure in spiral galaxies.
Percolation model incorporates the ideas of condensed matter physics and
statistical mechanics that allow long-range structure such as gravity to be
induced by short-range interactions. In this model, proposed by M.W.
Muellel and W. David Arnett, spiral structure is created using the theory
of percolation. In their theory, they imagine a spiral structure that has
risen from the outburst of star formation that propagates across the
galaxy. Using the proposed program, it will be shown that indeed spiral
structure can be created by short-range interactions, and not simply by
long-range forces such as gravity.},
