 We are all familiar with the idea of continuity. To be  continuous[1]  is to constitute an unbroken or uninterrupted whole, like the ocean or the sky. A continuous entity—a continuum—has no “gaps”. Opposed to continuity is discreteness: to be  discrete[2]  is to be separated, like the scattered pebbles on a beach or the leaves on a tree. Continuity connotes unity; discreteness, plurality.
