Basic information about Nikolai ChebotaryovNikolai Chebotaryov was born on June 15, 1894. After many years of school, he realized that he was talented in mathematics and soon after began his career as a mathematician at the age of fifteen. This is the age when he became deeply interested in mathematics. He had always been good at math, but had never thought about studying it until that age. His mother and father were very encouraging and wanted him to pursue what he was good at and what he loved: mathematics. Nikolai Chebotaryov's Mathematics Career He soon went to college in 1910, but fell ill with a bad case of pneumonia. , and had to postpone his college attendance until he was eighteen. He soon earned his four-year bachelor's degree in 1916 and then his master's degree in 1918 from Kiev University through a teacher named Dmitry Grave, a famous Russian mathematician. In 1921 he had to move to Odessa to help his parents, who had become seriously ill. But unfortunately his father died the year after Chebotaryov arrived in Odessa. But the year of his father's death he proved what he is best known for, the density theorem. This made Dirichlet's prime theorem more general, by an arrhythmic progression, which was used by a mathematician named Artin in his reciprocity law in 1927. Chebotaryov had a good job near Moscow, but was called to work in a , which is terrible work. , since it not only pays terribly, but is also very uninteresting; as a result, he resigned. Then he managed to find another job; however, that was another post. But he kept this job because it paid better than his previous job. He needed to hold down a job until he found a good one that he liked and… middle of paper… encountered setbacks in life. You can still achieve what you want even if there are obstacles, for example, Chebotaryov got sick with pneumonia when he was planning to go to college, but he went to college anyway because he wanted to achieve his long-term goal of having a good job with mathematics. An example of a setback I encountered was that some of my teachers at school each year were not the most helpful or encouraging. Nikolai Chebotaryov Overall, Chebotaryov taught me a lot, both mathematically and persevering in life. It mainly taught me life lessons and that you can do anything you really want if you put your mind and all your physical and mental strength into accomplishing what you want to do in life.
