The city of Paris once had these conditions, and it is a very sufficient condition. At the Royal Academy of Sciences in Paris, mathematicians from all over the world were recruited. Brenitz, who was born and raised in Germany, and Laplace, who came from a humble family, were both proud of their academic achievements. Even the French monarch spared no expense to support the work of the Royal Academy of Sciences in Paris, and took a large part to attract more people of insight. Such an enlightened system is a respect and admiration for talents and mathematics education. France gradually became the academic exchange center of Europe in the 17 and 18 centuries.
? They have a very strict education system. Due to the propaganda of the Enlightenment and the continuous development of rationalism in France, the French pay more and more attention to mathematics, and they know that the future mathematics center will be the center of the world to some extent. Therefore, from the student days, students will be consciously trained. They need to study calculus very hard, even including some learning skills of linear algebra. In addition, there are many excellent teachers in France, so it is not surprising that a number of mathematicians have been trained.
Next, I want to mention a very famous award, that is, the Fields Medal. According to statistics, mathematicians from France have won this award for more than 20 years. It is really hard for ordinary people to imagine that this country, which is famous for its romance and wine, has made such outstanding achievements in mathematics. It's really staggering.
