Given the universality of the iota-delta function, we can suppose that it can be used to describe natural phenomena. The description of physical systems can be thought of not only qualitatively (by means of colors) but also numerically by means of taking advantage of the numerical outputs of the function itself. A first point of interest is the control of the sum of the lines. By making a parallel between the iota-delta function and physical systems, if the position in the cellular net is assumed to be a spatial coordinate, the sum of the values of each line of the cellular automaton net is nothing but the amount of a given physical variable in the whole system. In conservative systems, it is clear that the sum of every line must be the same, and we multiply the iota-delta function by a scaling constant . This yields a quantitative interpretation of physical phenomena, as the value of a cell in the cellular automaton net is given as:
