In learning calculus, students develop intuitive ideas of such concepts as
limit, continuity, differentiability, and so on. This intuition is useful in
dealing with simple examples, but can be a positive hindrance to deeper
understanding of the basic concepts of mathematical analysis. The point of my
gallery is to challenge and refine the intuition of better calculus students and
students in advanced calculus (Math 409 here at A&M). Anyway, this stuff is
neat.
