Let’s talk about the history of relativity in Sinhala. I’m planning to cover following details in high level in this video.
“Galilean relativity” and his perception by observing the motion of objects.
Newton’s Laws of Motion, describing how bodies move in response to forces.
The Impact of James Clerk Maxwell’s Work. Also where Michael Faraday fits in the discovery of relativity timeline.
Albert Einstein was born March 14, 1879 in Ulm in southern Germany. His father was Hermann Einstein and mother Pauline Koch. In 1880 the family moved to Munich, where Albert later went to school. He was a dreamer and not particularly interested in school, and a teacher should have said: “There will never be one of you, Einstein.”
After two years of school in Aarau in Switzerland, where he took the initial studies and then began in 1896 to study at the ETH in Zurich (Zurich University of Technology). He had to make two admissions exams before he managed to enter the school. Four years later, he left the school as a teacher of mathematics and physics, and then served for two years as a teacher.
At the age of nineteen (1898), he met Hungarian Mileva Maric who was also a mathematician. They had a daughter in January 1902 that they adopted away, and they were married in January of the following year. In May 1904 they had a son named Hans Albert and 1910, the second son, Edouard.
Between 1901-1909, he worked at the patent office in Bern, Switzerland. He described that is his happiest time period. While he works in the office he researched and prepared three articles that were published in 1905. The first was about the Brownian motion in which he proved in practice the atoms and molecules’ existence. The second article was about the photoelectric effect, for which he received the Nobel Prize in Physics in 1921, and the third was the special theory of relativity, for which he is perhaps most famous. Shortly after he published his ideas on the measurement of relative distance, he expanded his work to include mass. One of his results became the world’s most famous equation, commonly written e = mc2.
At the age of thirty (1909), he left the patent office and served for some years as Professor in Zurich and Prague in 1914 before he became director of the Kaiser Wilhelm Institute for Physics in Berlin . 1916-17 he published his general theory of relativity. It represents a logical continuation of the “special relativity” (coming 1905).
During the 1930s, increased persecution of the Jews in Germany and Hitler’s rise to power in 1933, Einstein was with his Jewish background had to leave Germany. He resigned then also his German citizenship. He emigrated to the US in 1940 where he became a US citizen., he started as a professor at the “Institute for Advanced Studies” in Princeton In America. .
Just before the outbreak of war in 1939, the discovery of uranium fission, division. Some other scientists who feared that Hitler would let up a weapons project and start making nuclear bombs, managed to get Einstein to write a warning letter to the American President Roosevelt, and require a US atomic programs. It became the Manhattan Project, which led to the atomic bomb later dropped on Hiroshima and Nagasaki in Japan. Einstein did not attend himself in work on the bombs, but he objected to their being used, and after the war became a tenacious enemy against nuclear weapons.
In 1948 he was offered to become Israel’s first president, which he turned down. The reason he had was that he was “incapable of dealing with people.”
He died April 18, 1955 at a hospital in Princeton, New Jersey, USA, 76 year old. In 1999, 44 years after his death, he was a Time magazine named “Person of the Century” (the century person).
