Albert Einstein (born in March 14, 1879 in Ulm, † 18 April 1955 in Princeton, USA) was an American physicist of Swiss German-Jewish descent. His contributions to theoretical physics significantly altered the physical world.

Einstein's major work is the theory of relativity revolutionized our understanding of space and time. In 1905 his work was published, entitled On the Electrodynamics of Moving Bodies, whose content is now called the special theory of relativity. 1916 Einstein published the general theory of relativity. Even in quantum physics, he made major contributions: his explanation was for the photoelectric effect, which he had also published in 1905, him in November 1922, the Nobel Prize for Physics for 1921 awarded. His theoretical work played - contrary to popular opinion - the construction of the atomic bomb and the development of nuclear energy only an indirect role.
Albert Einstein is considered the epitome of the scholar and genius. However, he used his extraordinary popularity even outside the scientific experts in his commitment to international understanding and peace. In this context, he saw himself as a pacifist, a socialist and Zionist.

Albert Einstein was born in Ulm, the son of a Kaufman. Soon, however, the family moved to Munich, where his father Electrics devices produced. There, the young Einstein attended elementary school and high school. Later the family moved to Italy for business reasons. The young Einstein remained in Munich for a few months to make the school too. In the autumn of 1895 he went to Switzerland to study at the Technische Hochschule in Zurich at the department of teacher of mathematics and Phzsik too. In the summer of 1900, he passed the graduate teachers - Exam for Physics.

Thanks to the intercession of friends he was hired in 1902 at the patent office in Bern as an expert. His work was that he carefully perused the patent applications and also make a brief summary, it was decided in the usefulness of the invention. The Berne years were the happiest and most productive time in the life of Albert Einstein's scientific work. He published the first physical findings, which were quite different areas of physics: the theory of relativity, quantum theory and Brownian motion. Through this awareness, he paved the way to the first historical evidence of the real existence of atoms. These papers established his scientific reputation.

In the spring of 1909 Einstein was appointed as extraordinary professor of theoretical physics at the University of Zurich, and two years later, he worked at the University of Prague. In the summer of 1912 he returned to Zurich, he was appointed professor at the Technische Hochschule. On July 10, 1913 Einstein was appointed full-time regular member of the Royal Prussian Academy of Sciences in Berlin. Here Einstein finally found an activity which is entirely in keeping with his character and his full satisfaction. In 1916 he published his work "The basis of the general theory of relativity, which made him world famous.

In 1921, Einstein took a trip through the United States of America, and in the fall of 1922 after the Far East. In China and Japan, he held scientific lectures almost exclusively on questions of relativity. For his outstanding listings in the field of physics, Einstein received numerous honors from all countries. He was an honorary member of scientific Gesselschaft, honorary professor and honorary doctor of many universities.

In 1922 he received the Nobel Prize for Physics. In 1933, Einstein emigrated to the United States of America. He settled in Princeton, and dealt primarily with the continuation of his work Relativitätstheoretischen.

Einstein supported morally and materially the struggle against fascism, sci repeatedly warned strongly against the abuse of scientific knowledge for military purposes, and campaigned for the prohibition of nuclear weapons.

On 18 April 1955 is Albert Einstein died in Princeton.
