Torricelli's invention measures air pressure, demonstrating that air does indeed have weight, and that the pressure caused by that weight differs in different situations. -
Otto von Guericke Invents the Air Pump

Isaac Newton Publishes Philosophia Naturalis Principia Mathematica
Perhaps the most important event in the history of science, the Principia lays out Newton's comprehensive model of the universe as organized according to the law of universal gravitation.
