A Truly Beautiful Mind Class 9 Summary:

Albert Einstein was born on 14 March 1879 in the German city of Ulm. For about two and a half years, he could not speak, and when he did learn to say, he uttered every word twice. His playmates called him ‘Brother Boring’, and his mother regarded him as a freak because of the abnormally large size of his head. At school, his headmaster followed him as stupid and good for nothing. But he proved them all wrong.

At the age of 6, at the behest of his mother, he learned to play the violin. He became a gifted violinist. At the age of 15, his family shifted to Munich. He did not feel at ease with the strict regimentation of the school and left it for good. Later on, he joined the University in Zurich for higher education because the atmosphere there was more liberal and amenable to new ideas and concepts. He showed more interest in Physics and Mathematics. He met a fellow student, Mileva Maric, at the University- equally intelligent and clever. Later, they married and had two sons, but unfortunately, their marriage did not survive, and they divorced in 1919.

After completing his education, Albert worked as a technical expert in the patent office in Bern. Here, he worked secretly on his idea of relativity. In 1915, he published his paper on a particular theory of relativity, followed by the world-famous equation E = mc2.

In 1915, he published his paper on General Theory of Relativity, which gave a new definition to the concept of gravity. This theory made him a known personality. In 1919, during the solar eclipse, his approach became accurate and revolutionized physics. In 1933, he emigrated to the USA as Nazis had come to power in Germany. He did not want his finding and research to be used for destruction. In 1938, when Germany discovered the principle of Nuclear Fission, he was the first person to write to the American President about the dangers of the atomic bombs.

In 1945, when America dropped the Atomic Bombs on Nagasaki and Hiroshima, he was deeply hurt. He wrote to the United Nations for the formation of a world government to prevent the recurrence of such destruction. He spent his later days in politics advocating world peace and democracy. He died at the age of 76 in the year 1955.

Einstein is best known for developing the theory of relativity, but he also contributed significantly to developing the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics.

He received the 1921 Nobel Prize in Physics “for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect”, a pivotal step in developing quantum theory. His intellectual achievements and originality made ” Einstein ” synonymous with “genius”.
