“For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the universe in which some rule of maximum or minimum does not appear.” This is a quote by one the most intelligent, famous mathematicians of all time, Leonhard Euler. Euler contributed greatly to the fields of geometry, trigonometry, and calculus. Even after losing his sight, Euler continued to publish many articles and publications with his first book being Mechanica. Leonhard Euler was greatly admired for his many achievements and seniority in the field of mathematics. Within this essay, I will address the many achievements Euler accomplished in his life time and show how big of an impact he had to mathematics today. He continued to go in life as one of the most intelligent mathematicians and being a huge help…show more content… He had two younger sisters named Anna Maria and Maria Magdalena. He spent most of his adulthood in St. Petersburg, Russia and Berlin, Russsia. Though his father wanted him to be a rural clergyman, he began to show interest in the mathematics field. He went on to attend the University of Basel when he was only 13 and earned his masters degree while he was still a teenager! Years later in 1727, he moved to Russia and served in the navy. He then joined the St. Petersburg Academy as a professor in physics then later on became head of its mathematics division. In the year of 1734, he married Katharina Gsell and had many children. They were married for 39 years until her death. He then got remarried to her half-sister. In the mid 1740’s Euler was appointed the mathematics director of the newly created Berlin Academy of Science and Beaux Arts. Leonhard Euler was considered the best mathematician of the 18th century and I do not think anyone would argue with the fact that he acquired that
