When he saw the apple falling beside him, he start thinking : how and why the apple keeps falling down? What attracts the apple to the ground? After much research, he conclued that the Earth has a gravity like any planet or cosmic object. This gravity pulls objects towards the ground, allowing the existence of an atmosphere and preventing items from floating in the air. This scientific discovery has changed dramatically science in that time and it allowed us to invent machines that defy the law of gravity.

Sir Isaac Newton is considered one of the most brilliant minds in history. He was a key figure in the scientific revolution and an important contributor to various subjects such as optics, mechanics, calculus, astronomy and mathematics.

One of Newton's most important contributions were the laws of motion and gravity. These discoveries changed the way scientific thinking analyzed the world as they proved that the natural world is not random. Instead, it is ruled by precise and constant rules of physics that can be discovered through research.
