In 1905, when he was an unknown young physicist was employed at the Patent Office in Bern, Switzerland, published histheory of special relativity. Probably the most famous equation of physics at the grassroots level, is the mathematical expression of mass-energy equivalence, E = mc ², hededuced as a logical consequence of this theory. That same year he published another work that would lay some of the foundations of statistical physics and quantum mechanics.
In1915, he presented the theory of general relativity, which reformulated the whole concept of gravity. In 1919, when British observations of a solar eclipse confirmed hisprediction about the bending of light, was idolized by the press. Einstein became a popular icon of science world-famous, a privilege available to very few scientists.
Intheir explanation of the photoelectric effect and his many contributions to theoretical physics in 1921 won the Nobel Prize in Physics
the scientist left Germany to theUnited States, where he taught teaching at the Institute for Advanced Study in Princeton. Became U.S. citizen in 1940. During his last years he worked to integrate into a singletheory the gravitational and electromagnetic force. He died in Princeton, New Jersey on April 18, 1955.
Although considered the "father of the atomic bomb",in hiswritings he advocated pacifism, socialism and Zionism. It was proclaimed as the "character of the twentieth century" and as the preeminent scientist on the famous Time magazine
