Abstract:  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”.
