Theory of Relativity

If one has a glance at historical events related to theory of relativity, he may find that many theoretical results that mean a lot for physics and cosmology are included in it. The concept of theory of relativity begun to spring as Albert Einstein disclosed his researches about Special relativity. Work by Max Planck and Hermann Murkowski contributed a lot to help this broad theory develop and improve. Albert Einstein holds a special place in this place since he is considered a father for both general relativity and special relativity as well. He introduced the concept of general relativity in around 1907. In the time span of 1907 to 1915, many other theorists and physicist contributed their work and developed this very same theory at its peak. Theory of relativity still requires experimental verification in some of its concepts. Some physicists consider theory of relativity just a theoretical concern that can be proven practically. Despite of this criticism, the result extracted by analyzing the relativity theory are excessively important for practical engineering. Practical engineering is concerns about theory of relativity in following concepts:
GPS [Global Positioning System]
GLONASS
Galileo [Forthcoming one]
Concept of high precision dissemination of time
