阿尔伯特·爱因斯坦(1879-1955)，美籍德裔犹太人，1921年诺贝尔物理学奖获得者，现代物理学的开创者、奠基人，相对论——“质能关系”的创立者，“决定论量子力学诠释”的捍卫者(振动的粒子)——不掷骰子的上帝。他创立了代表现代科学的相对论，为核能开发奠定了理论基础，在现代科学技术和他的深刻影响下与广泛应用等方面开创了现代科学新纪元，被公认为是自伽利略、牛顿以来最伟大的科学家、物理学家。1999年12月26日，爱因斯坦被美国《时代周刊》评选为“世纪伟人”。
爱因斯坦于1955年逝世后，人们对其脑部拍摄了照片。通过对这些照片的研究，佛罗里达州立大学(Florida State University)的人类学家迪恩·福尔克(Dean Falk)发现，爱因斯坦大脑皮层有十几个与常人有异的细微之处，这些区别也许就是爱因斯坦能以全新视角诠释物理学的原因所在。福尔克博士的研究成果向我们表明，脑部是如何影响这个20世纪最著名智脑的思维活动的。
爱因斯坦似乎就是那个将构建崭新的物理学大厦的人。，特别是经过赫兹和洛伦兹发展和阐述的电动力学。爱因斯坦坚信电磁理论是完全正确的，但是有一个问题使他不安，这就是绝对参照系以太的存在。他阅读了许多著作发现，所有人试图证明以太存在的试验都是失败的。经过研究爱因斯坦发现，除了作为绝对参照系和电磁场的荷载物外，以太在洛伦兹理论中已经没有实际意义。
有一次，一个美国记者问爱因斯坦关于他成功的秘诀。他回答：“早在1901年，我还是二十二岁的青年时，我已经发现了成功的公式。我可以把这公式的秘密告诉你，那就是A=X+Y+Z! A就是成功，X就是正确的方法，Y是努力工作，Z是少说废话!这公式对我有用，我想对许多人也一样有用。
Albert Einstein was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"),he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".The latter was pivotal in establishing quantum theory.
Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light.
In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.He was visiting the United States when Adolf Hitler came to power in 1933 and did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming an American citizen in 1940.On the eve of World War II, he helped alert President Franklin D. Roosevelt that Germany might be developing an atomic weapon and recommended that the U.S. begin similar research; this eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery of nuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.
