Change no change, in physics, is a number representing a parameter. For example, the linear equation for distance (D) equals the rate (R) multiplied by time (T) as a function D(T)=RT. Since the distance is a function of time, D is called the dependent variable and the set of all possible values are called the range. T is the independent variable and the set of all possible values are called the domain. However, the rate or speed R is called the parameter of a particular function. It stays practically constant within a controlled predictable environment.

Wherever and whenever both R and T change independently then both become variables and the function D becomes nonlinear and unpredictable. For example if D represents the number of coins in one’s pocket and R represents spending and T represents saving then for constant or zero spending there is no problem predicting the change remaining after some change went in. On the other hand, if spending becomes erratic then a pocket full of change could end up empty of change. More so if there is a hole at the bottom acting as a black hole for disappearing change without actually spending any change, as a modern Shakespearean economist would say: change or no change that is the question.
