What is discreteness?

We know from mathematics that there are functions that are continuous, but there are also those that have discontinuities and, as it were, are made up of parts and pieces. The second kind of functions can be defined as discrete. Let us consider in more detail what discreteness is.

Discreteness is a property of a phenomenon or object that characterizes its discontinuity in the temporal, spatial or some other relation, as well as the possibility of division into elements. For example, time itself is discrete, since with its course we can distinguish individual fractional elements: hours, minutes, seconds, etc.

Discreteness is often used in scientific practice. For example, there is a discrete image or discrete algorithm. The latter is a sequence of actions to solve a problem, in which case each individual action is discrete. But not only in exact sciences, we can meet this word. Sometimes it is used by researchers from the humanities, for example, in sociology and philosophy, speaking of the discreteness of the same time or matter, the study of which has more than one hundred years.
