Special Relativity (MATH-426)
Introduction: Special Relativity, is the phsical theory of relativity formed by German physicist Albert Einstein in 1905. It is limited with the objects that are moving with respect to inertial frame of reference and is the origion of most famous equation of science E = mc^2, which expresses the fact that mass and energy are same physical entity and can be changed into each other. However,this physical theory of space and time based on the postulates that all the laws of physics are equally valid in all frames of reference moving at a uniform velocity and that the speed of light from a uniformly moving source is always the same, regardless of how fast or slow the source or its observer is moving. The theory has as consequences the relativistic mass increase of rapidly moving objects, the Lorentz-FitzGerald contraction, time dilatation, and the principle of mass-energy equivalence.
