Published in 1867 it not only explained gravity and the laws of motion but also dynamics and the movement of celestial bodies.
Newton later invented a scientific method involving four universal rules of investigation, which lead to the creation of his universal laws of nature, which practically explained every unsolved problem in physics during his day.
Newton also made significant development in the field of mathematics by inventing the mathematical system used today called calculus and make important calculations on the celestial motion. In addition, he made other advances in optics including the discovery that white light consists of different coloured strands. Newton also invented the first refracting telescope.
