Albert Einstein

Albert Einstein a was a great scientific and he took a big step he was a physical mathematical, he was German but then he had Swiss nationalized, he also had anothers nationalities like Italian and American

His parents moved to Munich when Einstein was an infant. The family business, was a manufacturer of electrical appliances, but the business broke and because to economic difficulties, they moved to Pavia, Italy, near Milan. In 1894. Albert remained in Germany to finish high school, which ended with mediocre grades, except in mathematics. The following year he joined his parents

At age of five he was sick so his father gave hem a compass and this wake up the interest of Albert Einstein of science, because its always pointed to the same place, which gave him to understand that he had forces behind all things.

He failed an examination that would have received a diploma in electrical engineering at the Polytechnic of Zurich. He returned in 1896 to the Polytechnic and graduated in 1900 as a secondary school teacher in mathematics and physics

and in 1901 adopted the citizenship of that country. However try to act as teacher, the way it was difficult, because their teaching methods were regarded as heterodox, which he lost three jobs. For two years he devoted himself to teaching replacing teachers or giving private lessons

On June 23, 1902 Einstein began serving as a technical expert of the Swiss Patent Office in Bern, where he worked until 1909.

In 1905 he received his doctorate from the University of Zurich presenting a thesis on the dimensions of the molecules

He attended for four years at the patent office as he began to excel in the scientific community and ascending in the academic world of the German language. First he went to the University of Zurich in 1909; After two years there he went to the University of Prague, in German, and in 1912 returned to the National Polytechnic Institute in Zurich. Finally, in 1913 he was appointed director of the Kaiser Wilhelm Institute for Physics in Berlin

In 1907, he began his work on the extension and generalization of the theory of relativity to all coordinate system. It began with the statement of the equivalence principle according to which the gravitational fields are equivalent to accelerations of the reference system. It was published in 1916.

He understood the variations of the rotational movement of the planets and predicted the slope of the starlight as it approaches bodies like the sun. As of 1919, it began to be recognized internationally getting awards of several scientific societies, including the Prize Nobel Prize in Physics in 1921

In 1933 he left for the United States. He obtained work at the Institute for Advanced Study in Princeton, New Jersey

In 1939 with other physicists sent a letter to President Franklin
