A Historical Figure Each Day—Albert Einstein

Albert

Albert Einstein (German/English: Albert Einstein; March 14, 1879 – April 18, 1955), born in Ulm, Kingdom of Württemberg, German Empire, was a theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics. His work is also known for its influence on the philosophy of science. He is best known in popular culture for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". [1-4]

Einstein graduated from the Swiss Federal Polytechnic School in Zurich in 1900 and acquired Swiss citizenship [1-4]. In 1905, he obtained a PhD from the University of Zurich and presented the photon theory, successfully explaining the photoelectric effect (for which he won the 1921 Nobel Prize in Physics) [1-4]; in the same year, he created the theory of special relativity, and in 1915, the theory of general relativity. In 1933, he moved to the United States and took up a post at the Institute for Advanced Study in Princeton, becoming a US citizen in 1940 while retaining his Swiss citizenship [1-4]. He died in Princeton, New Jersey on April 18, 1955, at the age of 76 [1-4]. In December 1999, Einstein was named "Person of the Century" by Time magazine.

Einstein's theories laid the theoretical foundation for the development of nuclear energy, and to help combat Nazism, with the assistance of people such as Leo Szilard, he wrote to US President Franklin D. Roosevelt, directly contributing to the launch of the Manhattan Project. After World War II, he actively advocated for peace, opposed the use of nuclear weapons, and signed the Russell–Einstein Manifesto [4-8]. Einstein pioneered the modern scientific and technological era, and is regarded as the greatest physicist after Galileo and Newton, as well as a pivotal figure in critical school scientific philosophy.
