Summary of A Truly Beautiful Mind Class 9th
Albert Einstein was born on 14th March 1789 in the German city of Ulm. When he was born he did not show any signs of greatness but his mother found him a freak as his head was so big. When he learned to speak he stuttered and repeated everything two times. His friends called him a boring brother so he played with his mechanical toys. He even thought of his sister Maja as a mechanical toy and asked about where her wheels were.
One day, his headmaster called his father and told him that it doesn’t matter what profession he chooses but he would not be able to make up anything.
But Einstein was good at every subject and scored good marks. He also joined a high school in Munich. He sometimes argued with his teachers and did not like the strict environment of the school so he decided to leave the school at the age of 15. His parents had moved to Milan and left him with relatives so that he could continue his studies in Switzerland.
Einstein was highly gifted in Mathematics and also had a keen interest in Physics so he decided to study to complete his graduation at a university in Zurich. He there found his love and he called her a clever creature. She was from Serbia and had come to pursue her degree in Switzerland. The couple fell in love and expressed their love through love letters which were a mixture of science.
Albert at the age of 21 got his university degree and after that, he also got a job as a technical expert in the patent office in Bern in 1920. While working there and assisting in others’ inventions was developing his own ideas too. He called his desk the bureau of theoretical physics.
One of the famous papers of 1905 was the Special Theory Of Relativity according to Einstein time and distance are not absolute. For example, two perfectly accurate clocks will not show the same time if they come together after a journey. From this followed the world’s most famous formula. It describes the relationship between mass and energy, E = mc2 (E stands for energy, m for mass, and c for the speed of light in a vacuum which is about 300,000 km/s.)
While he was being recognized by the world and media, his personal life was going well. His mother did not approve of his marriage to Mileva as she thinks it would not work as both of them are the same in intellect and she was three years older than him. The pair finally got married in 1903 but it did not work much and after having two sons they got divorced in 1919, Albert married his cousin Elsa in the same year.
Einstein turned a new leaf and this brought him world fame. In 1915, he published his General theory of relativity. He proved the accuracy of the eclipse of the sun in 1919 and hence his theory was approved worldwide. He was also awarded the Nobel Prize in 1921 for the same and received many honors and invitations from all over the world.
The Nazis came to power in Germany in 1933 and emigrated to the USA. Five years later after the discovery of nuclear fission by Nazis in Berlin, American Physicists got scared that they might build and use the atomic bomb.
Einstein wrote a letter to American President Roosevelt and warned him against the destruction caused by the single atomic bomb. The Americans discovered the bomb under a secret project. He was deeply shaken by the extent of the destruction caused by the Americans in the cities of Hiroshima and Nagasaki. Later on, he wrote a letter to the United Nations to form a world government so that work for peace could be done.
The letter made no response and in the next decade, he involved himself in politics and wanted to bring an end to the arms buildup. He also worked as a visionary and worked for peace and maintain democracy. Einstein died in 1955 at the age of 76. He was celebrated as a visionary and a world citizen.
