Newton described gravity and three laws of motion in the paper "Laws of Nature" published in 1687. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering.
By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, it is shown that the motion of ground objects and celestial bodies follows the same natural law. It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.
In mechanics, Newton expounded the conservation principle of momentum and angular momentum and put forward Newton's law of motion. In optics, he invented reflecting telescope, and based on the observation that a prism diverges white light into the visible spectrum, he developed the color theory. He also systematically expressed the law of cooling and studied the speed of sound.

In the book Mathematical Principles of Natural Philosophy published in 1688, he described gravity and three laws of motion. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering.
By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; Thus, the last doubt about the sun center was eliminated and the scientific revolution was promoted.
