Every object which initially does not move or be moved or any stationary object initially moving into silence, it happens because there are moving or stopping the object. We know him as a "force".
Why fruit falling or moving towards the earth's surface after detached from the stalk? Newton's law states that the fruit move, then there must be forces acting on the fruit. The force that causes the fruit or any object falling toward the earth's surface, called gravity. Talking about it for sure we will get to know one of the originators of the theory of gravity, Isaac Newton.
Sir Isaac Newton was born on December 25, 1642 in Woolsthorpe, Lincolnshire. He was a mathematician, physicist, natural philosopher, astronomer who came from England. His father died three months before Newton's birth.
His father was Isaac Newton and his mother Hannah Ayscough. When Newton was 3 years old, his mother remarried and left the Newton that was raised by his grandmother named Margery Ayscough. Newton did not like his stepfather and harbor hatred towards his mother for marrying the man.
With such versatility that makes the school gave her the opportunity to return to Newton in order to complete his studies with convincing his mother and his family. Finally, he was sent back to school by his mother so that she can finish her education. At the age of 18 he successfully graduated with a satisfactory value.
In June 1661, Newton received at Trinity College, Cambridge. Newton mastered math, science and physics. In 1665, he discovered the generalized binomial theorem and began to develop the theory that eventually evolved matekatika which we now know, the calculus. He likes to read the ideas of modern philosophers such as Descartes and astronomers such as Copernicus, Galileo, and Kepler.
Newton often do research at home for 2 years which prompted him to develop the theory of calculus, optics and the law of gravity. He graduated in 1665 and in 1667, he returned to Cambridge as a lecturer in Trinity.
In 1666. During the day Newton was reading about the theory of Copernicus, Galileo, and Kepler's orbit about the Earth beneath an apple tree. An apple fell on him. At that time he also started doing research. Seven years he had found the answer and then draw the conclusion that the moon also has appeal because the moon does not fall to earth as apples subjected to gravity.
Newton believed rationale Galileo, analytical geometry of Descartes and Kepler's laws on planetary motion. This is the third person who helped in the research. He formulated the three laws that regulate all movement in the universe of galaxies in the universe until elektroin revolves around the nucleus. There are three laws of Newton as follows:
- Newton's first law
Every object will have a constant speed unless there is not a zero resultant force acting on the object. Means that if the net force is zero, then the center of mass of an object remains stationary, or moving at a constant speed (not accelerating).
- Newton's second law
About the relationship between force, mass and acceleration, more greater the force that acting on an object, more greater the acceleration to , but more solid objects, more greater its deceleration.
- Newton's Law III
About action and reaction, that is, when an object exerts a force on the second, the second body also releases the same force, but in the opposite direction to the first body style.
In addition to knowledge about the universe, Newton also conducts research on light. In 1672, Newton became a member of the Royal Society, a group of scientists who are devoted to the experimental method (concerned with the terms of the experiment). He donated one of his telescopes bersaa, his research on light. Newton developed artificial Galileo telescope called the reflecting telescope.
In 1696, Newton was appointed as the Patron currency by the government. Duty to oversee the replacement of the British currency that has broken with the old and new currency more durable not only that, he is also responsible for the network dismantle counterfeiters.
Royal Society formed a small group, led by Robert Hooke to assess the findings of a new one is also to examine the findings of Newton. Hooke had his own ideas about light because he does not want to accept the findings of Newton. Because it is the two of them arguing.
In 1703, Newton was awarded the title of Sir, and he was also elected as Persiden Royal Society. He published his first work on light. The book includes an optical light color, reflectivity, and light spectrum . Findings regarding officially recognized by the optics in 1705 when he also became the first to receive a knighthood for his achievements in the field of science.
Newton's scientists achievement
- optics
Newton made great progress in the study of optics. In particular he developed a spectrum by splitting the white light through a prism.
- Telescope
Made significant improvements to the development of the telescope. However, when his ideas were criticized by Hooke, Newton withdrew from public debate. He developed an attitude antagonistic and hostile to Hooke, throughout his life.
- Mechanics and Gravity
In his famous book Principia Mathematica. Newton explained the three laws of motion which laid the framework for modern physics. It involves explaining planetary motion.
In 1727, Newton died at the age of 84 years. He was buried in Westminster Abbey for the royal family tomb, famous people, heroes, and scientists. To commemorate his dedication to science pictorial Newton invented currency.
