what is continuity vs discontinuity?
 Discontinuity refers to the “granularity” and discreteness of the spatiotemporal structure and state of matter, as well as the elements of which matter is composed, the aspects and forms of its existence, and the process of its motion and development.Functions which have the characteristic that their graphs can be drawn without lifting the pencil from the paper are somewhat special, in that they have no funny behaviors. The property which describes this characteristic is called continuity.
