Galileo Galilei

1564-1642
This great Italian scientist may be more responsible for the development of the scientific method of anyone. Galileo was born in Pisa, in 1564. While young people studying at the University of Pisa, but stalled because of financial affairs. Even so in 1589 he could be the position of lecturer at the university. A few years later he joined the University of Padua and stayed there until the year 1610. In this period he created a pile of scientific discoveries.
His first important contribution in the field of mechanics. Aristotle taught that heavier objects fall faster than lighter objects, and generations of intellectuals swallowed the opinion of the great Greek philosophers of this influence. However, Galileo decided to try first is whether, and through a series of experiments he concluded that Aristotle was wrong. The truth is, both heavy and light objects fall at the same speed except to the extent they decelerates due to a shift in the air. (Incidentally, the habit of throwing objects Galileo's experiment from the tower of Pisa apparently unconsciously). Knowing this, Galileo took further steps. By carefully measuring the distance of the fall he had at the time of the specified object and received evidence that the distance traversed by a falling object is directly balanced by the number of seconds squared falling objects. This discovery (which means the uniform acceleration) has its own significance. Even more importantly capable of collecting the results of Galileo's discoveries with mathematical formulas. Extensive use of mathematical formulas and mathematical methods is an important attribute of modern science.
Galileo's other major contribution was his discovery of the law of inertia. Previously, people believe that objects moving by themselves tend to be more slowly and completely stopped if there is no power that add strength to keep moving. But Galileo's experiments proved that the assumption was wrong. Where the power to slow down, such as shifting, can be eliminated, moving objects tend to keep moving indefinitely. This is an important principle that has been repeatedly affirmed by Newton and coupled with the system itself as the first law of motion of one of the vital principle in science. Leaning Tower of Pisa which is considered used by Galileo to demonstrate the laws of the fall of some object  Galileo's most famous invention is in the field of

Isaac Newton

Isaac Newton
( 1642 - 1727 )
Isaac Newton, scientists largest and most influential in the world who ever lived, was born in Woolsthrope, England, right on Christmas day 1642, the year coinciding with the death of Galileo. Like the Prophet Muhammad, he was born after his father died. In the boy he had shown real skill in the field of mechanics and very skillful use of his hands. Although children with a brilliant brain, the school seemed reluctant and did not attract much attention. When stepping on baliq passage, her mother out of school in the hope their children can be a good farmer. Fortunately the mother could be persuaded, that the main talent lies not in there. At age eighteen he entered the University of Cambridge. This is where Newton is quick to absorb what was then known to science and mathematics and very quickly as well start doing its own investigation. Between the ages of twenty-one and twenty-seven years he has laid the foundations of scientific theory which, in turn, then change the world.

Mid-17th century was a period of hatchery science. Discovery telescope near the beginning of the century has revolutionized the entire opinion about the science of astrology. English philosopher Francis Bacon and the French philosopher Rene Descartes both cried out to scientists all over Europe that no longer rely on the authority of Aristotle, but to experiment and research on the basic point of departure and his own purposes. What was put forward by Bacon and Descartes, has been practiced by the great Galileo. The use of telescopes, new findings by Newton for astronomical research has revolutionized the field investigation, and he did in the mechanics sector has resulted in what is now known as "Newton's laws of motion" of the first. Other great scientists, like William Harvey, discoverer of blood circulation affairs and governance inventor Johannes Kepler motion of planets around the sun, presents very basic information for the scholar. Even so, pure science is still a favorite of intellectuals, and still has not been proven - when used in technology - that science can change the basic pattern of human life as predicted by Francis Bacon. Although Copernicus and Galileo has been kicked to the side a few presumption digress about the ancient knowledge and has been presenting a more true understanding about the universe, but no one thought the subject was carefully formulated to be capable of turning the pile understanding landless and baseless as he arranged them in a theory that allows the development of predictions more scientific. None other than Isaac Newton was the one person capable of presenting a collection of neatly summarized the theory and laid the foundation stone of modern science that is now the current fad so people.
