DK Life Stories: Albert Einstein pdf

阿尔伯特·爱因斯坦（Albert Einstein，1879 年 3 月 14 日－1955 年 4 月 18 日）是德国、瑞士和美国的物理学家，父母是犹太人。在物理学中，他发表了一篇关于光电效应的研究论文，在他的其他三百篇同等科学论文中发表物质和能量，量子力学等，他的已证实结论导致了对许多经典物理学未能证明的科学现象的解释。 爱因斯坦从与牛顿的时空理论相矛盾的“狭义相对论”开始，特别是解决关于一般电磁波，特别是光的旧理论的问题，那是在瑞士（1902-1909 年）之间。 至于“广义相对论”，他是在1915年提出的，他在其中讨论了引力，它代表了现代物理学对引力的当前描述。 广义相对论通过将引力统一描述为空间和时间或时空的几何特性，来概括狭义相对论和牛顿万有引力定律。
