Gravitation


Sir Isaac Newton was a physicist, mathematics, astronomy, chemistry and philosopher who was born in England. Books written and published in 1687, Philosophiae Naturalis Principia Mathematica, described as the most influential book in the history of science. This work describes the laws of gravity and the three principles of (legal) movement, which changed people's view of the physical laws of nature to the fore during the three centuries and became the foundation of modern science.

In the year 1670 until 1672, Newton gave a lesson in optics. And during this period, he was himself investigating the refraction of light (refraction: the change direction of a wave due to the change in velocity) and provides a prism demostrasi that can break white light into various color spectrum and a prism lens in the second, can form a color spectrum become one white light re -

Isaac Newton realized that mathematics is a way to explain the laws of nature such as gravity, and make some formula to calculate 'body movement' and 'gravity'. Gravitation is the force that makes an object always moves falling down. With the three basic principles of the law of motion, Newton was able to explain and prove that the planet revolves around the sun in orbits that are oval and not a full round. Then Newton uses three basic principles of movement that is now known as Newton's Law to explain how things move.

Isaac Newton's father died three months after Newton was born, and the days of small, Newton lived with his grandmother. Newton then went to school in the village school and later moved to a better of school in Grantham, where he became a student there with the top ranking.

We have many stories to tell that Newton got the formula of the theory of gravity and an apple that fell from the tree. In profiled that one day sit down and learn Newton under an apple tree and it was an apple fall from the tree. By observing a falling apple, Newton concluded that there is something attractive force that the apple fell down, and the strength that we know today as the gravity.
