relativity 的定义

n. 名词 noun
  1. the state or fact of being relative.
  2. Physics. a theory, formulated essentially by Albert Einstein, that all motion must be defined relative to a frame of reference and that space and time are relative rather than absolute concepts: it consists of two principal parts. The theory dealing with uniform motion is based on the two postulates that physical laws have the same mathematical form when expressed in any inertial system, and the velocity of light is independent of the motion of its source and will have the same value when measured by observers moving with constant velocity with respect to each other. Derivable from these postulates are the conclusions that there can be no motion at a speed greater than that of light in a vacuum, mass increases as velocity increases, mass and energy are equivalent, and time is dependent on the relative motion of an observer measuring the time. The theory dealing with gravity is based on the postulate that the local effects of a gravitational field and of acceleration of an inertial system are identical.
  3. dependence of a mental state or process upon the nature of the human mind: relativity of values; relativity of knowledge.
