Continuity is the central nervous system of topology. In calculus, continuity is defined using epsilon-delta (
Long's textbook has garnered a reputation for its clarity and comprehensive nature. On platforms like Goodreads and Douban, readers frequently praise its quality. It is described as "a formal, comprehensive but concise treatment of point-set topology with well-crafted problems", and "an important introduction to topology" for higher-level studies. Many students and instructors appreciate its historical notes, which place key developments in context. However, some advanced readers have noted that certain core concepts are occasionally relegated to exercises, and that the book’s style, while thorough, can feel "terse," requiring dedicated effort from the reader.
