Albert Einstein


Albert Einstein (14 March 1879–18 April 1955) was a theoretical physicist who was considered as one of the biggest scientists in the 20th century. He found a theory of relativity and also gave contribution to the development of quantum mechanics, statistic mechanics, and cosmology. He got a noble in physics in 1921 for his explanation about the effect of photoelectric and “His devotion to theoretical physics".

After he formulated the theory of relativity, Einstein became well-known all over the world, an unusual achievement for a scientist. In his old age, his popularity was much higher than other scientists in history, and in popular culture. That is why people at that time considered him as a genius

Einstein was born in Ulm, Württemberg, Germany; about 100 km the east of Stuttgart. His father’s name was Hermann Einstein, a feather bed seller, who then worked in electrochemical. His mother’s name was Pauline. They got married in Stuttgart-Bad Cannstatt. They were descendants of Jewish families

Albert went to school in Catholic School, and it was because of his mother’s will he got a violin lesson. When he was five, his father showed him a pocket compass, and at that time, Einstein was aware that there was an action in this “Empty” room to the hand of compass; He then explained this experience as the most evocative moment in his life. Nevertheless, he was always considered as lazy student. It was perhaps because of dyslexia, and his shyness.

Einstein started studying math when he was 12 years old. But, at that lesson, he failed. Nevertheless, his uncles helped him develop his interest in intellectual world by giving him some suggestion and books about science and mathematic. In 1894, when his father failed in electrochemical business, Einstein’s family moved from Munich to Pavia, Italia (near Milan). But, Albert still stayed to finish his school before he could finally move to Pavia too. The next year, Einstein failed the entrance place in Eidgenössische Technische Hochschule (Technology Institution, Switzerland, at Zurich) and by his family, he was sent to Aarau, Switzerland, to finish his school, where he received diploma in 1896.

In 1898, Einstein met and fell in love with Mileva Maric, a Serbian girl, his classmate. In 1900, He was granted a teaching in Eidgenössische Technische Hochschule, which at the same time; he got citizenship of Switzerland in 1901. During this year he discussed his interest in science to his closed friends, including Mileva. And after they got married they got a daughter, named “Lieserl”, who was born in Januari 1902.

In 1905, when he got a doctor in Zurich, he wrote 4 articles which gave the basic of modern physics. A lot of physicists agreed that the three theses (about Brownian movement, the effect of photoelectric, and the special relativity) deserved the Nobel. However, it was only about the effect of photoelectric receiving the noble.
