The scientific revolution is a boundary between ancient thought and classical physics. Before the 19th century, there were many discoveries from many scientists such as Nicolaus Copernicus revived the heliocentric model of the solar system. Early 17th century Johannes Kepler proposed that the planets follow elliptical orbits, with the Sun at one focus of the ellipse. Galileo made use of experiments to validate physical theories. William Gilbert did some of the earliest experiments with electricity and magnetism. In 1687, Isaac Newton published the Principia Mathematica He succeeded in his physical theories: Newton's laws of motion and Newton's Law of Gravitation etc.
During the early 19th century Faraday, Ohm, and others studied the behavior of electricity and magnetism that led to the unification of the two phenomena into a single theory of electromagnetism, by James Clerk Maxwell
