beginning of its development received special relativity in the early 20th century, namely in 1905.Its foundations have been considered in the work of Albert Einstein's "On the electrodynamics of moving bodies".With this fundamental work of scientists raised a number of questions that had no answers at that time.For example, he suggested that the doctrine of Maxwell's true not fully.After all, the laws of electrodynamics, the interaction between a conductor and the magnet depends solely on the relativity of motion.But then there is a contradiction with the established views of what these two cases influence on each other must be strictly separated.Based on these findings, it is speculated that any coordinate systems that depend on the laws of mechanics, as much as, and sometimes more, depending on the optical and electrodynamic laws.This conclusion Einstein called "the principle of relativity."
Key elements of special relativity become revolutionary assumptions that marked the beginning of a completely new round of development of physical science.Scientist completely pushed classical notions of absolute space and time, as well as the Galilean relativity.He also made the move to the confirmation at the level of theory empirically proven Hertz finite speed of light.He laid the foundation for the study of the independence of the speed and direction of movement of the light source.
Today special relativity gives an opportunity to significantly accelerate the process of studying the universe.Designed by Albert Einstein eliminated the teaching of many of the contradictions that arose in the early twentieth-century physics.
The main objective pursued by the special theory of relativity - is to ensure communication between the installation space and time.This greatly simplifies the understanding of the whole world system in particular, and in general.The postulates of the special theory of relativity allows us to understand many phenomena: reduce the duration and longer during movement of the body, weight with increasing speed (mass defect), the lack of communication between the various events taking place in an instant (if they are in a completely different points of space-timecontinuum).All of this, he explains that the maximum speed of propagation of any signals in the universe does not exceed the speed of light in vacuum.
special theory of relativity states that the mass of the photon at rest is zero, which means that any outside observer never catch up on superluminal photon speed and be able to continue to move with it.So, the speed of light is an absolute value and can not be possible to surpass it.
Albert Einstein gave a new qualitative jump in the development of physical science in the world, and the scale of the universe.
