Character experience
Euler (Leonard,1April 70715-1September 783 18) was a Swiss mathematician and physicist. Born in Basel and died in St. Petersburg, Russia. Born in a priest's family, he was educated by his father since childhood. /kloc-entered university of basel at the age of 0/3, got his bachelor's degree at the age of 0/5, and got his master's degree at the age of 0/6. When he was in college, he received special guidance from johann bernoulli. After that, he devoted himself to mathematical research. At the age of 65,438+09 (65,438+0,726), he began to write articles and won the Paris Academy Award in one fell swoop. 1727, DanielBernoulli recommended him to work in St. Petersburg Academy of Sciences. 173 1 became a professor of physics, and 1733 succeeded Daniel Bernoni as a professor of mathematics. 174 1 year, he was invited by FredericktheGreat of Prussia to be the director of the Institute of Physical Mathematics of the Berlin Academy of Sciences. 1766, returned to St. Petersburg at the invitation of Russian Tsar Kadrin II until his death.
Major achievements
Euler is the most prolific mathematician in the history of mathematics. He published more than 500 papers and textbooks, and another 350 were published after his death. In fact, his works covered almost all branches of mathematics at that time. His main contributions are as follows: He has published three classic mathematical works: Introduction to Infinite Analysis (1748), Principles of Differential Calculus (1755) and Principles of Integral Calculus (1768- 1770), and put calculus into practice. Initiate modern trigonometry and modern number theory; Therefore, all branches of mathematics are unified and systematic; The study of the branch of graph theory is also triggered by solving the problem of the seven bridges in Konigsberg. He created or advocated the use of a large number of advanced mathematical symbols and obtained many important formulas, theorems and constant values. In addition to establishing pure mathematical theory, he also applied these mathematical tools to solve practical problems in astronomy, physics and mechanics, and achieved great results.
Euler is famous for his cleverness in completing complex calculations. 1735 was blind in the right eye due to overwork, and 177 1 year was blind in the left eye due to illness. With amazing memory and mental arithmetic ability, he persisted in his scientific creation after blindness and finished hundreds of scientific papers by dictation. In addition, his noble character of cultivating post-learning, caring for education has won wide respect from future generations. In Switzerland, Euler's portrait is printed on a ten-Swiss franc note as a tribute to him.
