Einstein derived the theory of special relativity in 1905, from principle now called the postulates of special relativity. Einstein's formulation is said[by...

Albert Einstein presented the theories of special relativity and general relativity in publications that either contained no formal references to previous...

Mach's principle.[page needed] There is a fundamental issue in relativity theory: if all motion is relative, how can we measure the inertia of a body...

principle of relativity and the principle of stationary action in mechanics can be used to derive Maxwell's equations, and vice versa. The theory of special...

Galilean relativity states that the laws of motion are the same in all inertial frames of reference. Galileo Galilei first described this principle in 1632...

General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed...

Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein...

However, this resulted in a limitation inherent in special relativity: the principle of relativity could only apply to inertial reference frames. To address...
