6、905年获苏黎世大学哲学博士学位。曾在伯尔尼专利局任职，在苏黎世工业大学担任大学教授。1913年返德国，任柏林威廉皇帝物理研究所所长和柏林洪堡大学教授，并当选为普鲁士皇家科学院院士。爱因斯坦在英国期间，被格拉斯哥大学授予荣誉法学博士学位。1933年因受到纳粹政权的迫害，脱离德国迁居美国，担任普林斯顿大学教授，从事理论物理研究工作。1955年4月18日，病逝于普林斯顿。爱因斯坦Pre-reading相对论是关于时空和引力的基本理论，主要由阿尔伯特爱因斯坦创立，依据研究的对象不同分为狭义相对论和广义相对论。相对论的基本假设是相对性原理，即物理定律与参照系的选择无关。狭义相对论和广义相对的区别是，前

7、者讨论的是匀速直线运动的参照系（惯性参照系）之间的物理定律，后者则推广到具有加速度的参照系中（非惯性系），并在等效原理的假设下，广泛应用于引力场中。相对论极大地改变了人类对宇宙和自然的“常识性”观念，提出了“同时的相对性”、“四维时空”、“弯曲时空”等全新的概念。它发展了牛顿力学，推动物理学发展到一个新的高度。相对论爱因斯坦反对残暴的政府，他反对纳粹政府并在纳粹政府掌权后不久就离开了德国。在其他人的影响下，爱因斯坦开始支持研制原子弹，以防止希特勒抢先研制成功，为此他还在1939年8月2日上书当时美国总统罗斯福（这封信很可能是别人执笔），建议开始研制核武器。罗斯福接受了建议，成立了一个小组负责研

8、究铀作为武器的可行性，几年之后这个小组被曼哈顿计划取代。战后，因为日本已经无条件投降，所以爱因斯坦开始为消除核武器建立和平政府游说，因为原子弹并不适合于军事训练所使用的武器。爱因斯坦与核能 爱因斯坦还联同史怀哲和伯特兰罗素为禁止核试验和核武器斗争。在他去世的前几天，他签署了罗素爱因斯坦宣言，这一声明促使帕格沃什科学和世界事务会议召开。Read the lesson and fill in the blanks.1879Einstein was born in _1905Einstein became a pioneer in the field of _1921Einstein receive
