Euler

Swiss mathematician and natural scientist. Born on April 15, 1707, Euler came from a pastor family in Basel, Switzerland. Influenced by his father from a young age, he developed a love for mathematics. He entered the University of Basel at 13, graduated at 15, and received his master's degree at 16. Euler was one of the most outstanding figures in 18th-century mathematics. Not only did he contribute greatly to the field, but he also extended mathematics into the realm of physics. He is the most prolific mathematician in history, writing over 800 pages of papers on average every year, as well as numerous textbooks on mechanics, analysis, geometry, and calculus. Works like "Introduction to the Analysis of the Infinite," "Foundations of Differential Calculus," and "Foundations of Integral Calculus" have become classics in mathematics. Euler's research was so extensive that many important constants, formulas, and theorems in various branches of mathematics are named after him. Besides mathematics, he was also involved in architecture, ballistics, navigation, and other fields. Charles Kleiber, Switzerland's Secretary of State for Education and Research, once said, 'Without Euler's numerous scientific discoveries, our lives would be completely different.' French mathematician Laplace also believed: 'Read Euler, he is the teacher of all.'
