Über die spezielle und die allgemeine Relativitätstheorie

Albert Einstein was born on March 14, 1879 in Ulm. He spent his childhood in Munich where his family owned a small machine shop. By the age of twelve, Einstein had taught himself Euclidean Geometry. His family moved to Milan, where he stayed for a year, and he used it as an excuse to drop out of school, which bored him. He finished secondary school in Aarau, Switzerland and entered the Swiss Federal Institute of Technology in Zurich. Einstein graduated in 1900, by studying the notes of a classmate since he did not attend his classes out of boredom, again. His teachers did not like him and would not recomend him for a position in the University. For two years, Einstein worked as a substitute teacher and a tutor before getting a job, in 1902, as an examiner for a Swiss patent office in Bern. In 1905, he received his doctorate from the University of Zurich for a theoretical dissertation on the dimension of molecules.

Einstein also published three theoretical papers of central importance to the development of 20th Century physics. The first was entitled "Brownian Motion," and the second "Photoelectric Effort," which was a revolutionary way of thinking and contradicted tradition. No one accepted the proposals of the first two papers. Then the third one was published in 1905 and called "On the Electrodynamics of Moving Bodies." Einstein's words became what is known today as the special theory of relativity and said that the physical laws are the same in all inertial reference systems and that the speed of light in a vacuum is a universal constant. Virtually no one understood or supported Einstein's argument.

Einstein left the patent office in 1907 and received his first academic appointment at the University of Zurich in 1909. In 1911, he moved to a German speaking university in Prague, but returned to Swiss National Polytechnic in Zurich in 1912. By 1914, Einstein was appointed director of the Kaiser Wilhelm Institute of Physics in Berlin. Hi
