| Abstract from DBPedia | In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates: 1.
* The laws of physics are invariant (that is, identical) in all inertial frames of reference (that is, frames of reference with no acceleration). 2.
* The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or the observer.特殊相対性理論（とくしゅそうたいせいりろん、独: Spezielle Relativitätstheorie、英: Special relativity）、特殊相対論とも。一般相対性理論と合わせて単に相対性理論とも呼ばれる。 光速に近い速度で相対移動する観測者対を設定し、互いの見え方や光の見え方を整理することで時間と空間の関係を捉える物理学の理論。 (Source: http://dbpedia.org/resource/Special_relativity) |
