Gravitation - Movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth. (Oxford Dictionary)
Introduction :
For centuries, mankind has always been fascinated by the celestial bodies. The motion of the stars and planets were at once a symbol of the divine order of the universe and a profound challenge for human understanding.
For the ancient Greeks the separation between the terrestrial and celestial realms was absolute--the downward motion of falling objects was thought of as a "natural tendency" towards the center of the earth. The Greeks believed explaining motion on earth was a completely different problem from explaining why the earth went around the sun.

This had profound philosophical and scientific consequences. The unification into what became the laws of gravitation became a symbol of the predictive and quantitative power of science. The fact that a single law could explain the motion of a cannonball and the motion of Mars revolutionized our understanding of our place in the universe.
In the centuries after Newton, scientists and mathematicians created powerful techniques and concepts for understanding complex phenomena such as tides and perturbations. In 1915 Albert Einstein published a new theory of gravitation (The General Theory of Relativity) that conceived of gravitational effects as caused by curvature in a four-dimensional space-time surface. Although Einstein's theory explains some observations that Newton's cannot, the inverse square law has remained an important tool in modern astrophysics and cosmology. Moreover, Newton's and Kepler's laws of gravitation can explain almost all the phenomena of orbits and terrestrial motion with which we will be concerned here. “Their conversation is awkward, especially when she mentions Wickham, a subject Darcy clearly wishes to avoid” (SparkNotes Editors,
