The phenomenon of continuity is existentially ubiquitous. It is in essence, non-stop repetitions towards an end point. For example, walking, running, speaking, singing, playing, working, living, etc. The repetitions do not have to be homogeneous. For example, running may transit into walking without stopping. In many cases, the end point is finitely placed. In other cases, the end point is infinitely placed. No matter its manifestations, continuity is in essence, motion towards its finite or infinite end point. Consequently, it is expressions of Pj Problems .
The continuum offers a mathematical definition of the important concept of continuity in the mathematical sense.
