"Periodicity" Quotes from Famous Books
 ... rhythm is the maintenance of specific temporal relations among the elements of the series of sensations which supports it. It is true that the subjective experience of rhythm involves always two factors, periodicity and accentuation; the latter, however, is very readily, and under certain conditions inevitably, supplied by the apperceptive subject if the former be given, while if the temporal conditions be not fulfilled (and the subject cannot create them) no impression of rhythm ...

... media the 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 of the prophylactic ...

... 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 ...

... "the Demon'') of b Persei, a star of the second magnitude, noticed by G. Montanari in 1669 to fluctuate in brightness. John Goodricke established in 1782 the periodicity of its change in about 2d 21h and suggested their cause in recurring eclipses by a large dark satellite. Their intermittent character prompted the supposition. The light of Algol remains constant during close upon 56 ...

... white cold fog. The sky may 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 ...

... fluid secretion, the gastric juice; in the utero-ovarian plexus, where no secretion is required, the blood itself is discharged. It is difficult, with these facts, to understand the assertion that, "Periodicity is the grand (i.e. exclusive) ...

... 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 who had not ...

... 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, ...

... which furnishes the working powers of consciousness and action has its annual, its 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 the ...
