Who was Isaac Newton and how did his observations contribute to the scientific community as a whole?
Newton's observations about the physical world were mathematically modeled and could adequately predict how objects reacted given proper motivation. He is responsible, not only for the theory of Gravity, but also how motion and reaction played into the the field of physics. In addition, he created the mathematical branch of Calculus, which he could use to explain his scientific findings. Calculus, Gravitational theory, and Newtonian laws of motion are still in wide acceptance to this day.
