Person: Kepler, Johannes


Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He is known for his first, second, and third planetary law of motion. The possibility of being able to describe the laws of heavenly motions by earthly mathematics positively influenced the boldness of contemporary mathematicians and finally led to the invention of Newton's theory of gravitation. He also did important work in optics and geometry.
