19 giug 1687 anni - Sir Isaac Newton

Descrizione:

publishes his “Principia”, which describes an infinite, steady state, static, universe, in which matter on the large scale is uniformly distributed. In the work, he establishes the three Laws of Motion (“a body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force”; “force equals mass times acceleration”; and “to every action there is an equal and opposite reaction”) and the Law of Universal Gravitation (that every particle in the universe attracts every other particle according to an inverse-square formula) that were not to be improved upon for more than two hundred years. He is credited with introducing the idea that the motion of objects in the heavens (such as planets, the Sun and the Moon) can be described by the same set of physical laws as the motion of objects on the ground (like cannon balls and falling apples).
