presented to the court of the scientific community in the beginning of the last century, the theory of relativity created a furor.Its author, Einstein, for decades defined the main areas of physics research.But do not forget that the German scholar in his works used numerous achievements of their predecessors, including the famous Galilean principle of relativity - the famous Italian scientist.
much of his life dedicated to the study of the Italian scientist mechanics, becoming one of the founders of this branch of physics like kinematics.Galileo's experiments allowed him to come to the conclusion that the fundamental differences at rest and uniform motion is not - the point is, what point of reference will be accepted.The famous physicist, pointed out that the laws of mechanics are valid not for any one chosen coordinate system, and for all systems.This principle went down in history as the Galilean relativity principle, and the system became known as inertial.
His theoretical calculations scientist with pleasure is confirmed by numerous examples from the life.The most popular example of a book that is on board the ship: in this case with respect to the ship itself, it is at rest, and relative to the observer on the shore, it moves.The principle of Galileo confirms its position that peace between movement and there is no difference.
formulated so Galilean relativity principle among his contemporaries made a furor.The fact is that before the publication of works by the Italian scientist were all convinced of the truth of the teachings of the ancient Greek scientist Ptolemy, who claimed that the Earth is absolutely fixed body with respect to which there is a movement of other cases.Galileo destroyed this view, opening new horizons for science.
At the same time, we can not in any way nor to idealize the Galilean relativity principle or law of inertia.After all, on the basis of this wording, it can be concluded that all these provisions are completely in all the speed and distance between the bodies, but it is not.The first step of the teachings of Galileo, Newton's theory of relativity was the development of Gauss, Weber, Gerber and theoretical foundations of the phenomenon, which was called "retarded potential."
neither Galileo nor Newton into force of the then level of knowledge could not even guess that the approach speed of the body to the speed of light the laws of inertia simply cease to function.And, in general, the principle of Galilean relativity is ideal only for those systems, which consist of two bodies, that is, the impact of other objects and phenomena they are so small that they can be neglected.Movement in such a system (eg the Earth's rotation around the sun) later became known as absolute, all other movements are called relative.
