Webprimitive concept, familiar from undergraduate physics and mathematics, applies equally in general relativity. An example of a vector is d~x, the difference vector between two infinitesimally close points of spacetime. Vectors form a linear algebra (i.e., a vector space).

The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein; special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of … See more Albert Einstein published the theory of special relativity in 1905, building on many theoretical results and empirical findings obtained by Albert A. Michelson, Hendrik Lorentz, Henri Poincaré and others. Max Planck See more Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists and mathematicians, see History of special relativity). … See more Einstein stated that the theory of relativity belongs to a class of "principle-theories". As such, it employs an analytic method, which means that the elements of this theory are not based on hypothesis but on empirical discovery. By observing natural processes, we … See more • Doubly special relativity • Galilean invariance • General relativity references • Special relativity references See more General relativity is a theory of gravitation developed by Einstein in the years 1907–1915.
