Isaac Newton is a great scientist and has great influence that ever lived in the world. He was born in Woolstrope, England, precisely on Christmas day in 1642, coincide year to the death of Galileo. in his childhood he has shown the real skill in the field of mechanic and very handy in using his hands.
Even though Newton has very bright brain, when he was child, he was looked reluctantly in his school and did not many drawing attention.
When he was adult, his mother took him out from his school with hope his son can be a good farmer. Fortunately the mother can be persuaded that his main talent is not located there. At the age of eighteen years old he entered Cambridge University. In there Newton quickly absorbed what is then recognized as science and mathematics and fast also making his own research. Between the age of twenty one and twenty seven years old he has put the base of scientific knowledge which in turn then change the world.
In year 1668, Newton designed and also built the first reflection telescope which is used by most of star researchers now. In the field of mathematics Newton presented his greatest discovery, namely “integral calculus” which is the most important work in the growing of modern mathematics theory and development of modern knowledge.
The most important discoveries of Newton in the field of mechanics, namely knowledge about motion of a body. Galileo is the first founder of law which described motion of an object if it is not influenced by external force. Basicly all object are influenced by external force and the most important problem is in mechanics is how object moves in that condition. This problem is solved by Newton in his second law of motion and it can be acknowledged as the main law of classical physics. The second law (mathematically can be described by the equation F = ma) settles that object acceleration is equal to the nett force divided by mass of the body. To those two laws, Newton add his third law which is famous about motion (striking that in each action, for example physical force, there is reaction which is equal and in opposite) also the most famous in his discovery about scientific norm of universal gravitation law. These four laws if combined, will form a unity system which hold for all macro system of mechanics, begin from the shaking of pendulum until motion of planets in their orbits around the sun which can be observed and their motion can be predicted. Newton does not only settle mechanics law, but he also used the device of mathematics calculus, and he showed that these fundamental formulae can be used for problem solving.
In year 1678 Newton published book of his famous work mathematical principle about natural philosophy (usually abbreviated Principia only). In that book Newton provided his theory about the law of gravitation force and the law of motion, he showed how those laws can be used to estimate precisely motion of planets around the sun. the main problem of astronomical motion is how to estimate the right position and motion of the stars also planets, so solved at all by Newton only by one strike. Of his works Newton is often acknowledged the greatest astronomer of all the greatest.
Another great scientist of Leibniz which does not at all close to Newton even ever involved in a strick fight said: “By all about mathematics and from the world develops until the presence of Newton, that man which gives the best contribution.” Also honor is given by great French scientist, Laplace: “Newton’s Principia book is far above all products of genius men in the world.” And Laplace also stated that Newton is the greatest genius who ever lived. While Ernst Mach in his writing in year 1901 said, “All of mathematics problems which have been solved since his life is the base development of mechanics based on Newton’s laws. “This may be the most complicated of Newton great discovery: he found separation vessel between facts and laws, able to draw several miracle but does not much help to make guests; he inherits to us series of unity of laws which is able to be used for physics problems in the secret scope of very large and contains possibility to make the right guests.
Newton died in year 1727, buried in Westminster Abbey.
