That paper introduced what later became tobe called thespecial theory of relativity. A confirmation of the gravitational red shift was difficult to determine because of the many competing effects that result in a shifting or broadening of solar or stellar spectral lines. The special theory of relativity Some ten years before the rst review of thegeneral theory of relativity,Einstein published his famous paperOn the Electrodynamics of Moving Bodies(Einstein 1905). Consequently, there had to be restriction of the admissible coordinate systems to what he began to call “adapted coordinates.” Einstein tried to encourage experimental efforts aimed at testing the two main predictions of the theory. In November 1915 Einstein finally completed the general theory of relativity, which he considered to be his masterpiece. Einstein concluded that generally covariant field equations cannot uniquely determine the physical processes in a gravitational field. Its most salient features are length contraction and time dilation in a system that is in uniform relative motion to an observer with a speed comparable to that of light. It presented a conceptual analysis of the notions of space and time, with a critical reassessment of the meaning of simultaneity at its core. It includes a self-contained exposition of the elements of tensor calculus that are needed for the theory. This paper was the first comprehensive overview of the final version of Einstein's general theory of relativity after several expositions of preliminary versions and latest revisions of the theory in November 1915. This chapter discusses Albert Einstein's reviews paper on general relativity theory.
