Statue and Summary of Accomplishments


Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws.
He did this by demonstrating the consistency between
Kepler's laws of planetary motion and his theory of gravitation.

In doing so, he removed the last doubts about
heliocentrism.  In his "I stand on the shoulders of giants" commentary, he gave special credit to Galileo,

Essential to his laws is the concept of an "Inertial Reference Frame."
Newton is generally recognized as being one of the most influential scientists of all time.
