爱因斯坦是20世纪物理学史上的传奇.1905年对他具有里程碑式的意义，连续发表的5篇论文成为他科学生涯的第一个高峰期.其中一篇题为《关于光的产生与转换的一个启发性观点》的论文，为他摘取了1921年诺贝尔物理学奖桂冠.普朗克非常赏识爱因斯坦的天赋.海尔布隆评价：“普朗克的第二个最重要发现就是爱因斯坦”.

 Einstein is a legend in the history of physics in the 20th century. 1905 was a milestone for him, and his five consecutive papers became the first peak of his scientific career. One of them, entitled “an enlightening view on the generation and transformation of light”, he won the Nobel Prize in physics in 1921. Planck appreciated Einstein’s talent very much. Helbron commented: “Planck’s second most important discovery is Einstein”.
