Albert Einstein (14 March 1879 – 18 April 1955) was a German-born scientist. He worked on theoretical physics.[1] He developed the theory of relativity.[2][3] He received the Nobel Prize in Physics in 1921 for his theoretical physics. His famous equation is {\displaystyle E=mc^{2}} {\displaystyle E=mc^{2}} (E = energy, m = mass, c = speed of light).
Before his job, Einstein thought that Isaac Newton's idea of gravity was not completely accurate. He developed the special theory of relativity in 1902-1909 to correct that. However, he realized that the gravitational fields could also extend the relativity. So, he published a paper on general relativity in 1916 with his theory of gravitation.
In 1933, Einstein was visiting the United States. In Germany, Adolf Hitler came to power. Einstein, being of Jewish ethnicity, did not return to Germany due to the Hitler regime’s anti semitic policies.[4] He lived in the United States and became an American citizen in 1940.[5] On the beginning of World War II, he sent a letter to President Franklin D. Roosevelt explaining to him that Germany was in the process of developing a nuclear weapon; so Einstein recommended that the US should begin similar research. This eventually led to the Manhattan Project.
Einstein was born in Ulm, Württemberg, Germany, on 14 March 1879.[6] His family was Jewish, but was not very religious. However, later in life Einstein became very interested in his Judaism. Einstein did not begin speaking until he was 2 years old. According to his younger sister, Maja, "He had such difficulty with language that those around him feared he would never learn".[7] When Einstein was around 4 years old, his father gave him a magnetic compass. He tried hard to understand how the needle could seem to move itself so that it always pointed north. The needle was in a closed case, so clearly nothing like wind could be pushing the needle around, and yet it moved. So in this way Einstein became interested in studying science and mathematics. His compass gave him ideas to explore the world of science.
When he became older, he went to a school in Switzerland. After he graduated, he got a job in the patent office there. While he was working there, he wrote the papers that first made him famous as a great scientist.
Einstein married with a 20-year-old Serbian woman Mileva Marić in January 1903.
In 1917, Einstein became very sick with an illness that almost killed him. His cousin Elsa Löwenthal nursed him back to health. After this happened, Einstein divorced Mileva in 14 February 1919, and married Elsa on 2 June 1919.
Children
Edit
Einstein's first daughter was "Lieserl" (no one knows her real name). She was born in Novi Sad, Vojvodina, Austria-Hungary in the first months of 1902. She spent her very short life (believed to be less than 2 years) in the care of Serbian grandparents. It is believed she died from scarlet fever.[8] Some believe she may have been born with the disorder called Down syndrome, although it never proves. No one knew her very existence until 1986, when Einstein's granddaughter discovered a shoe box containing 54 love letters (most of them from Einstein), exchanged between Mileva and Einstein from 1897 to September 1903.[9]
Einstein's two sons were Hans Albert Einstein and Eduard Tete Einstein. Hans was born in Bern, Switzerland in May 1904 and Eduard was born in Zürich, Switzerland in July 1910. Eduard died at 55 years old of a stroke in Psychiatric University Hospital Zurich . He had spent his life in and out of asylums due to his Schizophrenia.
Later life
Edit
Just before the start of World War I, he moved back to Germany, and became director of a school there. He lived in Berlin until the Nazi government came to power. The Nazis hated people who were Jewish or who came from Jewish families. They accused Einstein of helping to create "Jewish physics," and German physicists tried to prove that his theories were wrong.
In 1933, under death threats from the Nazis and hated by the Nazi-controlled German press, Einstein and Elsa moved to Princeton, New Jersey in the United States, and in 1940 he became a United States citizen.
During World War II, Einstein and Leó Szilárd wrote to the U.S. president, Franklin D. Roosevelt, to say that the United States should invent an atomic bomb so that the Nazi government could not beat them to the punch. He was the only one who signed the letter. However, he was not part of the Manhattan Project, which was the project that created the atomic bomb.[10]
Einstein, a Jew but not an Israeli citizen, was offered the presidency in 1952 but turned it down, stating "I am deeply moved by the offer from our State of Israel, and at once saddened and ashamed that I cannot accept it."[11] Ehud Olmert was reported to be considering offering the presidency to another non-Israeli, Elie Wiesel, but he was said to be "very not interested".[12]
