The discussion centers on the value of reading "Course of Higher Mathematics" by Smirnov, particularly for self-study in mathematics and physics. Participants express mixed feelings about the book's relevance due to its Soviet origins, with some arguing that it provides a comprehensive range of mathematical concepts and is beneficial for understanding analysis, especially for physicists. Concerns about the book being outdated are raised, but others counter that Soviet-era texts often excel in clarity and problem-solving examples, fostering a deeper intuitive understanding. The discussion also touches on the quality of Soviet textbooks compared to modern ones, with some asserting that many contemporary texts lack rigor.
