"Periodicity" Quotes from Famous Books
 ... periodicity, and the periodicity of animal and vegetable life, are simultaneously used in the first stages of progress for estimating epochs. The simplest unit of time, the day, nature supplies ready made. The next simplest ...

... twice in succession on the same day of the week. Turning to the landlord of the hotel I asked, "What is the rule for holding the Court? When is it held?" "Every forty days at twelve o'clock at noon" was the reply. Reflection showed that so strange a periodicity related to no notation of time with which we are now in touch; it must belong to a system that has passed away; but ...

... himself in any case of doubtful expediency, before discussion is exhausted, and where the difference may well seem one of personal pique rather than of considerate judgment. This is to degrade us from a republic, in whose fore-ordered periodicity of submission to popular judgment democracy has guarded itself against its own passions, to a mass meeting, where momentary interest, panic, or persuasive sophistry—all of them gregarious influences, and all of them contagious—may decide by a shout ...

... are supposed to be only small ones, and to be dissipated into dust and vapor at the time of their sudden heating; so numerous are they that 40,000 have been counted in one evening, and an exceptionally great display comes about once in 331/4 years. The inference from their periodicity is, that they are small bodies moving round the sun in orbits of their own, and that whenever the earth crosses their orbits, thereby getting into their path, a splendid display of meteors results. ...

... and discovery, and never to any great extent those of propagation. Indeed, for twenty years I entirely abandoned the scientific rostrum, and almost ended my labors, feeling that my duty had been done in the way of development and demonstration. But in accordance with the great law of periodicity, I resumed my labors ...

... monthly, its diurnal waves, even its momentary ripples, in the current it furnishes. There are greater and lesser curves in the movement of every day's life,—a series of ascending and descending movements, a periodicity depending on the very nature of the force at work in the living organism. Thus we have our good seasons and our bad seasons, our good days and our bad days, life climbing and descending in long or short undulations, which I have called ...

... remain perfectly blue for weeks in every other direction, and Pele's head remain always hidden. In order to make a successful ascent, one must not wait for a period of dry weather,—one might thus wait for years! What one must look for is a certain periodicity in the diurnal rains,—a regular alternation of sun and cloud; such as characterizes a certain portion of the hivernage, or rainy summer season, when mornings and evenings are perfectly limpid, with very heavy sudden rains in the middle of the day. It is of no use ...

... nature. It is, then, purely an assumption, an interesting figment of the mind, that certain curious disturbances in the electrical state of the air and the earth, affecting delicate electric instruments, possessing a marked periodicity in brief intervals of time, and not yet otherwise accounted for, are due to the throbbing, in the all-enveloping ether, of impulses transmitted from instruments controlled by the savants of Mars, whose insatiable thirst for knowledge, and presumably burning desire to learn whether ...

... with the banks, in order to defeat the restrictions upon them, has no parallel but in the sponging-houses. A Belgian philosopher, from the study of statistics, has deduced a certain order in disorder,—or a law of periodicity in the recurrence of murders, suicides, crimes, and illegitimate births; and it appears that a similar regularity of irregularity might be easily detected in our cyclic ...

... "Periodicity," Steve said promptly. "Is there any regularity in the sightings? Do they occur every three, four, or five days, or once a week on Mondays? Which reminds me. You might put down the day of the week, too. There's a calendar on the ...

... them killed more frequently than if they clung to the legal crossings, but kept the motormen, the chauffeurs, and the truck-drivers in a stew of profane nervousness. So the traffic policemen led harried lives; they themselves were killed, of course, with a certain periodicity, but their main trouble was that they could not make the citizens realize that it was actually and mortally perilous to go about their city. It was strange, for there were probably no citizens of any length of residence ...

... Time in one way only—by counting repeated motions. Apart from the operation of the physical Law of Periodicity we should have no natural measures of Time. If that statement be true it follows that apart from the operation of this law we could not attain to any knowledge of Time.[11:1] Perhaps this latter proposition may not at first be readily granted. ...

... the empty programme of philosophy, we may name certain special problems that have appeared in its history. Since this history comprehends the activities of many individuals, a general validity attaches to it. There has been, moreover, a certain periodicity in the emergence of these problems, so that it may fairly be claimed for them that they indicate inevitable phases in the development of human reflection upon experience. They represent a normal differentiation of interest which the individual mind, in the course ...

... number of observations that every action tends to repeat itself under similar conditions. Habits of life and mind are thus formed so that in time they become quite involuntary and automatic. A cumulative effect is obtained by attention to this matter of periodicity, while the use of the same place for the same purpose tends to dispose the mind to the performance of particular functions. In striving for psychic development of any sort we shall do well not to disregard these facts. For since all actions tend to ...

... planets farther away from the sun, the other to draw them all into it. On the one hand, every body in our system which contains fluid matter has tides raised upon its surface by the attraction of neighbouring bodies. All the planets raise tides upon the surface of the sun and the periodicity of sun-spots (or solar cyclones) depends upon this fact. These tidal waves act as a drag or brake upon the rotation of the sun, somewhat diminishing its rapidity. But, in conformity with a principle of mechanics well known to astronomers, though not familiar to the general reader, ...

... bones were transported before final deposition. The final sites of deposition, the fissures, were inundated occasionally by floods alone, or because of changes in location of the channel of the stream at the time of flooding. The periodicity of deposition of the sediments within portions of the fissures is indicated by the stratification of the bone conglomerate ...

... thinking principle itself. The criterion is in the word "vibrations." However delicately etheric the substance its movement commences by the vibration of its particles, and a vibration is a wave having a certain length, amplitude, and periodicity, that is to say, something which can exist only in terms of space and time; and as soon as we are dealing with anything capable of the conception of measurement we may be quite certain that we are not dealing with Spirit but only with one of its vehicles. Therefore although we may push our ...

... excursion-trains, art museums, periodical literature, and exciting novels; prone even to scientific theorizing and cursory peeps through microscopes. Old Leisure was quite a different personage. He only read one newspaper, innocent of leaders, and was free from that periodicity of sensations which we call post-time. He was a contemplative, rather stout gentleman, of excellent digestion; of quiet perceptions, undiseased by hypothesis; happy in his inability to know the causes of things, preferring the things themselves. He lived chiefly in ...

... disease, par excellence, of the Gaboon is the paroxysm which is variously called Coast, African, Guinea, and Bullom fever. Dr. Ford, who has written a useful treatise upon the subject,[FN7] finds hebdomadal periodicity in the attacks, and lays great stress upon this point of chronothermalism. He recognizes the normal stages, preparatory, invasional, reactionary, and resolutionary. Like Drs. Livingstone and Hutchinson, he holds fever and quinine "incompatibles," and he highly approves ...

... precaution turned out useless. All day the men rolled logs into the current below the dam. The click! clank! clank! of their peavies sounded like the valves of some great engine, so regular was the periodicity of their metallic recurrence. They made quite a hole in the breast; and several times the jam shrugged, creaked and settled, but always to a more solid look. Billy, the teamster, brought down his horses. ...

... beginning of 1911 he came under the observation of one of us at the Johns Hopkins Hospital Dispensary. His case was followed minutely for some months when the following extraordinary clinical picture was seen to develop with regular periodicity. His interest would gradually withdraw from his work and an abstracted, "dim" look come into his eyes. He ceased to sleep either day or night. Ideas, in the intervals latent, would become more insistent, and he talked of them in a distracted way ...

Stanley Hall, the father of child study in this country, has so well said: "Our will should be a rock, not a wave; our requirements should be uniform, with no whim, no mood or periodicity about them." Having made sure of ourselves, we need not fear that training our wilful ...
