Philosophiæ Naturalis Principia Mathematica
Two central figures in the early modern age are Galileo Galilei and Isaac Newton. Galileo's final statement of his mechanics, particularly of falling bodies, is his "Two New Sciences" (1638). Newton's 1687 "Philosophiæ Naturalis Principia Mathematica" provided a detailed mathematical account of mechanics, using the newly developed mathematics of calculus and providing the basis of Newtonian mechanics.
