بازانیگی ِ ویژه bâzanigi-ye vižé
*Fr.: relativité restreinte*
The theory formulated by A. Einstein in 1905, which is based on the following
two → *postulate*s:
1) → *Principle of relativity*:
The laws of physical phenomena are the same when studied
in terms of two reference systems moving at a constant velocity
relative to each other.
2) → *Principle of constancy*:
The → *velocity of light* in free space is the same for all
observers and is independent of the relative velocity of the source of
light and the observer.
The term "special theory of relativity" refers to the restriction in the
first postulate to reference systems moving at a constant velocity relative
to each other (→ *inertial reference frame*).
See also → *general relativity*. → *special*; → *relativity*. |
