OPM Disability Retirement: The Calculus of Change
The title itself is somewhat of a tautology, for the branch of mathematics is defined as a study of change, divided into differential calculus and integral calculus; both, concerning the function and limits of mathematical constancy and potential quantum leaps for purposes of analyzing quantitative future applications. We all assume some amount of change; if there is a differential to be considered, the rate of such change can be significant over an extended period of time, whereas the initial analysis can be a minimal irrelevancy. It is the exponential rate of change applied over a lengthy period, which can produce change significant enough to enter into the calculus of future indicators. […]
