Albert Einstein was born in March 14, 1878 in Ulm, Germany. His parents Herman and Pauline (Koch) Einstein were very worried about young Einstein because he was very slow to learn how to speak. When he was young he had no mark of being a genius. He was Jewish but went to a Catholic school were he was the worst in class. When he was young his parents moved several times looking for a place to open businesses, his parents settled in Italy when he was 15. He soon was expelled from school in Germany and joined his family in Italy. He finished high school in Switzerland; were he graduated with a teaching degree from the Swiss Federal Institute of Technology, however he did not find a job until 1902 at the Swiss patent office. He worked there for seven years. In 1903 he married Maria Maric. He had three children, 2 boys and one girl. Liserl was given up to adoption in 1902.
In 1905 Einstein published various papers in the German Yearbook of Physics, three of them became very famous (probably because they were so complicated that other scientist were astonished at his capacity to think) One of them is probably the most famous he ever invented. The special theory of relativity. This showed that neither time, weight, or mass is constant. When moving at high speeds time, weight, and mass get compressed. Einstein said it happens because energy is equal to mass times the speed of light square, it is usually represented as E = mc2. He became famous and was highly respected. When the war in Berlin broke out his wife and kids moved back to Switzerland and soon after that they divorced in 1919. Sometime after the divorce of Maria and Einstein he married his cousin Elsa. Gravity was a big problem for scientist because whenever scientists worked out a natural law, gravity would always confuse the scientists. Einstein knew he wasn't an exception and he knew his special theory had problems. He wrote the general theory of relativity in 1915.
