欧拉是18世纪里最优秀的数学家,他很重视数学的普及教育,经常亲自到中学去讲授数学知识,为学生编写数学课本.尤其感人的是,1770年,年迈的欧拉双目失明后,仍然念念不忘给学生编写《关于代数学的全面指南》.这本著作出版后,很快就被译成几种外国文字流传开来,直到20世纪,有些学校仍然用它作基本教材. Euler was the most outstanding mathematician in the 18th century. He attached great importance to popular education in mathematics, and often went to teach mathematics in high school and wrote mathematics textbooks for students. Particularly touching was that in 1770, the elderly Euler lost his eyesight. Afterwards, I still kept in mind not forgetting to write “Comprehensive Guide to Algebra.” After this book was published, it was quickly translated into several foreign languages. Until the 20th century, some schools still used it as a basic teaching material.
