“As Magnitudes themselves are absolute Quantums Independent on all Kinds of Measure, tho' indeed we cannot tell what their Quantify is, unless we measure them; so Time is likewise a Quantum in itself, tho' in Order to find the Quantity of it, we are obliged to call in Motion to our Assistance as a Measure… and thus Time as measurable signifies Motion; for if all Things were to continue at Rest, it would be impossible to find out by any Method whatsoever how much Time has elaps'd; and the several Ages wou'd roll on imperceptibly and undistinguish'd. Do I say we shou'd not perceive how Time flows? No indeed, nor any Thing else, but remain like Stocks or Stones in a continual Insensibility. We perceive nothing, unless so far as we may be instigated by some Change affecting the Senses, or that our Souls are mov'd and excited by the internal Operation of the Mind. We esteem the Quantities and different Degrees of Things according to the Extension or Intension of Motions striking upon us either interiorly or exteriorly. So that the Quantity of Time so far as we can observe; depends upon the Extension of Motion.”

“Momentum may be roughly described as quantity motion. A body moving at a speed of say twenty an hour, has a certain quantity of motion. If the body goes forty miles an hour there is twice as motion; or if twice as much matter goes twenty miles hour, there is also twice as much motion. Momentum is measured by the quantity of matter moving at a rate mass \times velocity.”

“Calendars and clocks exist to measure time, but that signifies little because we all know that an hour can seem as eternity or pass in a flash, according to how we spend it.”

“Micro-motion study, presented for the first time at this meeting, is a new and accurate method of recording and transmitting skill. Based upon the principles of motion study and time study, it makes possible simultaneous measurement of both time and path of motions. It produces an entirely different result from any of the methods attempted by its predecessors, in that it shows a measured difference in the time of day on each and every cinematograph picture, even when the pictures are taken at a rate much faster than ever considered in work where positive films are printed and projected upon the screen.”

“There is much to be known,” said Adaon, “and above all much to be loved, be it the turn of the seasons or the shape of a river pebble. Indeed, the more we find to love, the more we add to the measure of our hearts.”

“Friends are found on the battlefield, and unfortunately friends are also lost. And where do we find the measure of that sacrifice? How can we account for the value of that loss? Sometimes we can find an answer in our sense of country, at other times in our Corps. But clearly we can see it in the lives that were able to continue due to the acts of others who were not so fortunate.”

Jim Webb (1946) American politician, military officer and author

“But you may perhaps wonder why I explain Time without Motion, and will say, does not Time imply Motion? I answer no, as to its absolute and intrinsic Nature; any more than it does Rest. The Quantity of Time, in itself, depends not on either of them; for whether Things move on, or stand still; whether we sleep or wake, Time flows perpetually with an equal Tenor.”

“It cannot be justly inferr'd… We do not perceive the Thing, therefore there is no such Thing, that is a false Illusion, a deceitful Dream, that wou'd cause us to join together two remote Instants of Time. But nevertheless this is very True… That is, for as much Motion as there was, so much Time seems to have been elapsed; nor, when we mention such a Quantity of Time, do we merely mean any Thing else, than the Performance of so much Motion, to the continued successive Extension of which we imagine the Permanency as Things is co-extended.”

“What if we stopped celebrating being busy as a measurement of importance? What if instead we celebrated how much time we had spent listening, pondering, meditating, and enjoying time with the most important people in our lives?”
