Einstein's postulates of relativity
WebSpecial 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 … In physics, Albert Einstein's 1905 theory of special relativity is derived from first principles now called the postulates of special relativity. Einstein's formulation is said to only require two postulates, though his derivation implies a few more assumptions. The idea that special relativity depended only on two postulates, … See more 1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference. 2. Second postulate (invariance of c) As measured in any inertial frame of reference, light is … See more Without a "bridging hypothesis" as a third postulate, the 1905 derivation is open to the criticism that its derived relationships may only apply See more Einstein's special theory is not the only theory that combines a form of lightspeed constancy with the relativity principle. A theory along the lines of that proposed by Heinrich Hertz (in … See more Historically, Hendrik Lorentz and Henri Poincaré (1892–1905) derived the Lorentz transformation from Maxwell's equations, which served to explain the negative result of all aether drift … See more Einstein's 1905 derivation is not complete. A break in Einstein's logic occurs where, after having established "the law of the constancy of the speed of light" for empty space, he invokes … See more In the rigorous mathematical formulation of special relativity, we suppose that the universe exists on a four-dimensional spacetime M. Individual points in spacetime are known as events; physical objects in spacetime are described by worldlines (if … See more
