Summary

Much of our understanding of the world depends on describing how things change. Algebra and geometry are useful tools for describing relationships among static quantities, but they do not include concepts appropriate for describing change. Calculus is the study of change in a function, when the independent variable changes, how does the dependent variable change. The basic concept is rate of change, and the basic tool is limit.

Mathematical analysis provides the deepest understanding for the concept of limits. It deals with the existence and uniqueness of limits; the necessary and condition for differentiability and Riemann integrability; the conditions for interchanging the order of different operations.

Remind that, there are many other types of integrals, and there are types of limits. In topology, we have the net limit, using the concept of neighborhood. Once we unite all concepts of limits, it is the grand unification of mathematics.
