# Special Theory of Relativity by M Usman Hamid and M Zeeshan Ahmad

Special theory of relativity developed by Einstein in 1905, after the failure of Newton‘s laws, when he was dealing with the relative motion in space. The theory of relativity deals with relations which exist between physical quantities (such as mass of a particle, length of a rod, electric field at a point etc.) as they appear to different observers in relative motion. The observers considered in this book are restricted to those in inertial frames of reference. The theory is then called restricted theory or Special Theory of Relativity (STR). When no such restriction is made, the theory is called the General Theory of Relativity. In 1915, Einstein developed General Theory of Relativity.
