Einstein did a lot of research in various fields of physics and contributed a lot to new inventions and discoveries. The most famous special theory of relativity integrated mechanics and electromagnetism, and the general theory of relativity established a new theory of gravitation by applying the theory of relativity to unequal motion. His other contributions include the cosmology of relativity, capillary action, chronological perceptual chromaticity, the classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian motion of molecules, the probability of molecular transitions Photon formed the basis of the theory), a theory of radiation that also included the subject of stimulated emission, the first concept of an integrated field theory and the geometry of physics.
Adolf Hitler came to power in Germany in 1933, when he was a professor at the Berlin Academy of Sciences. Being Jewish, Einstein emigrated to the United States at that time and never returned to Germany. He settled in the United States and became a U.S. citizen in 1940. [2] Before World War II, he wrote a letter to US President Franklin D. Roosevelt. In the letter, he warned that Germany could "make a different kind of impossibly powerful bomb" and urged the United States to launch a similar study. It was through this letter that the work on the Manhattan Project began. Although Einstein supported the Allies, he was against the use of the atomic bomb. Russell-Einstein later co-authored the Manifesto with the British philosopher Bertrand Russell, outlining the dangers of the atomic bomb. Until his death in 1955, he was associated with Princeton University's Institute of Advanced Study.
Einstein's research is contained in more than 50 scientific papers and some non-scientific books. [3] In 1999, Time magazine named Einstein "the best man of the century." It is also known from a poll of famous physicists that he is recognized by almost everyone as the best physicist of all time. [4] The term "Einstein" is now used to refer to someone or something who is gifted and intelligent in general culture and everyday use. That is, it is synonymous with merit. [5]
Biography
Early childhood and early education
Einstein was born on March 14, 179 (the year of the death of James Clark Maxwell, the most famous theoretical physicist of the nineteenth century), in the city of Ulm. [6] He spent his childhood in Munich. Einstein's parents were secular middle-class Jews. Father Herman Einstein originally made and marketed bird feather beds. He later set up an electrical factory in Munich with great success. The name of this company was Elektrotechnische Fabrik J. Einstein & Cie which first electrified the Oktoberfest in Munich and connected Schwabing with the first electric wire. His mother Pauline Koch was in charge of all the internal affairs of the family. He had a sister named Maza. He was born two years after Einstein. Two things in his childhood gave birth to immense wonder in his mind. He first got a compass at the age of five and was amazed at its use. How is the compass needle changing direction due to invisible energy? From then on, he had a lifelong fascination with the unseen. [6] At the age of 12, he became acquainted with a book on geometry. He enjoyed reading the book so much that he called it the "book of sacred little geometry" for life. [6] The book was actually Euclid's Elements. His first school was the Catholic Elementary School. Despite his eloquence, he was one of the best students in elementary school. [9]

Albert Einstein (age 14) in 1893. Picked up before the family moved to Italy.
At the age of 12, Einstein suddenly became very religious. He mastered various songs and verses in school praising the Creator. His ability to speak was not very good, but he did very well in school. But after reading books on science, his religious consciousness began to wane. Because his religious beliefs were in conflict with scientific theory. And the theories of science were definitely proven. In such a situation, the authorities of the then Jewish-controlled educational institution were not particularly pleased with him. Einstein took up the violin at the tender age of 7 at the behest of his mother. I didn't like playing the violin very much, so I gave it up. Later, however, he showed special interest in Mozart's violin tunes. At this time he used to make various equipments by himself and show them to others. From this time onwards, his special interest in mathematics and his talent are known.
At the Luitpold Gymnasium, he became indifferent to Prussian style of teaching and practice, unable to keep up. That education was enough to destroy creativity and originality. One teacher, however, told Einstein that nothing great would happen to him. At the time, he was particularly influenced by Max Talmud, a medical student. From time to time he would go to their house to eat the invitation. At one point, Einstein took on the role of an unannounced instructor. [6] Talmud introduced him to higher mathematics and philosophy. At the age of 18, he became interested in a particular subject. Earlier, Talmud introduced him to a series of pediatrics written by Aaron Bernstein (Naturwissenschaftliche Volksbucher, 18-7). In this book, the author talks about the experience of traveling with electricity as well as moving through a telegraph wire. Einstein then asks himself, what would happen if light could be traveled in this way? This question kept revolving in his mind for the next 10 years. He thinks that if he travels at the same speed as light, the light will look stable, just like a frozen wave. Since light is composed of waves, then static light waves will appear. But static light waves have never been seen or cannot be seen. This is where a helium is born that makes him think. It was Talmud who introduced him to Euclid's Elements and Emanuel Kant's Critique of Pure Reason. By reading Elements Einstein can know the process of descending because of the search process. After mastering Euclidean geometry at the school level, he turned his attention to calculus. Einstein's father wanted his son to be an electrical engineer, but he was interested in pure knowledge. He is a great scientist.
