狄利克雷(Dirichlet)是德国著名的数学家,解析数论的主要创始人,1805年2月15日出生。少年时代,他对数学产生了浓厚兴趣,常把零花钱积攒起来购买数学书籍。中学时代,他是一名专心致志、品学兼优的学生。中学毕业时,父母希望他攻读法律,但狄利克雷酷爱数学,父母最终尊重了他的选择,把数学作为终身从事的事业。 19世纪20年代,德国的大学只重视教学不注重研究,普遍水平不高。在数学界仅有高斯一人是享誉世界的数学家。相比之下,法国是当时的世界数学中心,拥有拉普拉斯、勒让德、傅立叶、泊松等一批著名的数学家,于是狄利克雷离开家乡前往巴黎求学。他先后进入法兰西学院和巴黎理学院学习,还曾在一位法国将军家里当家庭教师,有机会结识了法国许多著名学者。1825年,20岁
Dirichlet was a famous German mathematician and the founding father of analytic number theory. He was born on February 15, 1805. As a teenager, he had a great interest in math and often saved his pocket money to buy math books. In high school, he is a dedicated, good student. When he graduated from high school, his parents wanted him to go to law, but Dirk Nowitzki loved mathematics, and eventually parents respected his choice of math as a lifelong career. In the 1820s, German universities only emphasized that teaching did not pay attention to research and the general level was not high. In the mathematical world, only Gauss is a world famous mathematician. In contrast, France was the world’s mathematical center of the time, with a number of famous mathematicians including Laplace, Legendre, Fourier, Poisson and so Dirichlet left for Paris to study. He studied at the Faculty of Law in Paris and the Faculty of Science at Paris and also worked as a tutor at a French general who had the opportunity to meet many famous French scholars. 1825, 20 years old
