Newton’s Law of Gravitation was an
ENORMOUS achievement, because
1. It synthesized the laws that govern motion on
Earth and in the heavens.
2. Newton’s work had a profound effect on
philosophical thought. His research implied that
the universe was a rational place that could be
described by universal, scientific laws.
