JOHANNES KEPLER

Dates of dscoveries

While Copernicus and Galileo often receive the credit in the popular imagination, it was Johannes Kepler (1571-1630) who discovered and demonstrated that the Earth orbits the Sun.In his 1609 work, Astronomai Nova ("The New Astronomy"), Kepler demolished the Aristotelian cosmography of perfect forms and unknowable causes, forever changed man’s sense of his places in the Universe, helped launch the scientific revolution--and also identified problems which would motivate the development of calculus.
