Over three centuries ago, Isaac Newton invented a new kind of mathematics called calculus so that he could model motion in the natural world using mathematics. Calculus is about measuring change and so ... Newton was able to make a mathematical model that encompassed both objects falling because of gravity on Earth,

His three laws of motion and his law of gravitation, however, are still one of the first things that all physics students learn, and are the basis behind a lot ... Although Newton made many very important contributions to the world of science, the most important to astronomy were his laws of motion and law of gravity.

Issac Newton, a 17th-18th century English physicist and mathematician (also the guy who had an apple hit his head supposedly), stated three laws that basically describe the statics and dynamics of objects. Statics is the study of forces on an object at rest. ... Also, gravity changes its direction by making it fall down.

Along with his Three Laws of Motion, Newton also outlined his law of gravity in the 1687 book Philosophiae naturalis principia mathematica (Mathematical Principles of Natural Philosophy), which is generally referred to as the Principia.

FROM THE MOUTHS OF SCIENCE STUDENTS: ... "The tides are a fight between the Earth and moon. All water tends towards the moon, because there is no water in the moon, and nature abhors a vacuum. I forget where the sun joins in this fight." ... "Vacuum: A large, empty space where the pope lives."
