I see confusion when the term Moderne Mathematics is used here in USA. With my experience with french mathematics, the term Moderne Mathematics stands for New Mathematics, a field developed during the 1960's by the Bourbaki group in France. The merit of that field is that it provides the Foundation Classes for Software Engineering, like the design of computer operating systems or computer programming languages. Without its contributions, software engineering is just like hardware engineering, a pure black art running by tinkers and hackers. I found that Microsoft Windows operating systems programming is more easily understandable when the New Mathematics approach is employed.
