Theory of Relativity

Einstein’s theory of relativity is a famous theory, but it’s little understood. The theory of relativity refers to two different elements of the same theory: general relativity and special relativity. The theory of special relativity was introduced first and was later considered to be a special case of the more comprehensive theory of general relativity. General relativity is a theory of gravitation that  Albert Einstein  developed by between 1907 and 1915, with contributions from many others after 1915. THEORY OF RELATIVITY CONCEPTS Einstein’s theory of relativity includes the interworking of several different concepts, which include: Einstein’s Theory of Special Relativity – localized behavior of objects in inertial frames of reference, generally only relevant at speeds very near the speed of light Lorentz Transformations – the transformation equations used to calculate the coordinate changes under special relativity Einstein’s Theory of General Relativity – the more comprehensive theory, which treats gravity as a geometric phenomenon of a curved spacetimecoordinate system, which also includes noninertial (i.e. accelerating) frames of reference Fundamental Principles of Relativity WHAT IS RELATIVITY?
