用英文介绍爱因斯坦

Einstein, Albert

born March 14, 1879, Ulm, Württemberg, Ger.

died April 18, 1955, Princeton, N.J., U.S.

German-Swiss-U.S. scientist.

Born to a Jewish family in Germany, he grew up in Munich, and his family moved to Switzerland in 1894. He became a junior examiner at the Swiss patent office in 1902 and began producing original theoretical work that laid many of the foundations for 20th-century physics. He received his doctorate from the University of Zürich in 1905, the same year he won international fame with the publication of three articles: one on Brownian motion, demonstrating the existence of molecules; one on the photoelectric effect, in which he demonstrated the particle nature of light; and one on his special theory of relativity, which included his formulation of the equivalence of mass and energy (E = mc2). He held several professorships before becoming director of Berlin's Kaiser Wilhelm Institute in 1914. In 1915 he published his general theory of relativity, which was confirmed experimentally during a solar eclipse in 1919 with observations of the deviation of light passing near the Sun. He received a Nobel Prize in 1921 for his work on the photoelectric effect, his work on relativity still being controversial. He made important contributions to quantum field theory, and for decades he sought to discover the mathematical relationship between electromagnetism and gravitation, which he believed would be a first step toward discovering the common laws governing the behaviour of everything in the universe, but such a unified field theory eluded him. His theories of relativity and gravitation represented a profound advance over Newtonian physics and revolutionized scientific and philosophical inquiry. He resigned his position at the Prussian Academy when Adolf Hitler came to power and moved to Princeton, N.J., where he joined the Institute for Advanced Study. Though a longtime pacifist, he was instrumental in persuading Pres. Franklin Roosevelt in 1939 to initiate the Manhattan Project for the production of an atomic bomb, a technology his own theories greatly furthered, though he did not work on the project himself. The most eminent scientist in the world in the postwar years, he declined an offer to become the first prime minister of Israel and became a strong advocate for nuclear disarmament.

爱因斯坦 [Einstein, Albert]

(1879.3.14,德国 符腾堡 乌尔姆～1955.4.18,美国 新泽西州 普林斯顿)

德裔美籍科学家。出生于犹太家庭，在慕尼黑长大，1894年迁居瑞士阿谑小T就读于苏黎世的一所技术学校(1900年毕业)，在这段期间他放了德国公民身份；有多年时间无国籍，1901年才入籍瑞士。1902年爱因斯坦成为瑞士专利局的初级检验员，开始进行独创的理论工作，为20世纪物理学奠定了许多理论基础。1905年获得苏黎世大学博士学位，同年一连发表3篇论文从而赢得国际声誉：一篇论述布朗运动，依据分子运动的能量来解释；一篇论述光电效应，证实了光的粒子性质；一篇论述他特有的相对论，包括物质的质量与能量的等效性(E=mc2)。他拥有数个教授职位，1913年出任柏林威廉皇帝物理研究所主任。1915年发表了广义相对论，在1919年一次日食中观察太阳近处光的偏离，获得实验上的肯定。1921年因在光电效应方面的工作而获颁诺贝尔物理学奖，而在相对论方面的工作仍有争议。他对量子场论有重要的贡献，几十年来致力于找出电磁作用与万有引力之间的数学关系，他相信这是找到宇宙中统御物体行为之***同定律的第一步，但这样的统一场论并未被研究出来。他在相对论和引力方面的理论远胜过老式的牛顿物理学，对科学和哲学的探讨掀起了一场革命。当A.希特勒掌权时，他辞去普鲁士科学院的职位，迁居美国新泽西州普林斯顿，到高级研究院工作。虽然长期奉行和平主义，却在1939年出面说服F.罗斯福总统启动曼哈顿工程，以制造原子弹。虽然他并没有亲自参与这项工作，他的理论却大大推进了这项技术。1940年爱因斯坦成为美国公民，但仍保有瑞士籍。身为战后世界最赫赫有名的科学家，他拒绝出任以色列第一任总理，而成为倡导核裁军的有影响力的人士。
