# Title: Simple Particle Simulator
# Description:
"""
I am hoping to assemble a series of brief educational computer programs that will capture the simplicity and elegance of laws of physics, both in nature and in apprehension.

This particular educational project (Simple Particle Simulator) is the first of this series. In less than 25 lines, plotting and comments aside, we can obtain the trajectory of a particle in ANY force field. The generated plot displays the simulated and exaggerated perihelion precision of Mercury.
