Laplace used mathematical methods to prove the size of the orbit of planets only cyclical changes, which is the famous Laplace's theory. He published more than 270 papers in astronomy, mathematics and physics, specializing in a total of more than 4006 pages. Among the most representative special works are "Astro-Mechanics", "Cosmic System Theory" and "Probability Theory". In 1796, he published "The Theory of the Universe".
