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. […] Read More …

OPM Disability Retirement: Etymology versus Entomology

The difference in spelling involves more than a single letter; but in using the words in a sentence, the subtle distinction of a single consonant makes for all the relevance in the world. One refers to the very history and evolution of words, their meaning and usage; the other is a branch of a larger discipline of arthropodology, the subset of which focuses upon insects and the study thereof. In speech, therefore, the mistaken insertion of the consonant can create a hilarious situation resulting from the unknowing misuse of the word; whereas, in written form, it would probably be quickly identified as a misspelling and overlooked without appreciating the “funny-ness” of the error.
