"Periodic" Quotes from Famous Books



... head appeared again, but without any unusual turbidity in the applied water. Investigation, however, showed the presence of large quantities of organisms, particularly melosira and synedra, in the applied water, and examinations in subsequent years have shown a periodic recurrence of these forms in quantities sufficient to cause the trouble mentioned. In June, 1907, examination showed repeatedly more than 1,000 and 1,500 standard units of melosira per cu. cm., and one count showed nearly 3,000 ...

... altogether, one may therefore assume that the so-called captured comets are disintegrating at a comparatively rapid rate. Kepler long ago maintained that "comets die," and this actually appears to be the case. The ordinary periodic ones, such, for instance, as Encke's Comet, are very faint, and becoming fainter at each return. Certain of these comets have, indeed, failed altogether to reappear. It is notable that the members of Jupiter's comet ...

... numerous eating-houses meals are provided at very moderate charges, and at Panama and Colon large, up-to-date hotels are maintained by the American Government. These are used very extensively by the Canal staff, and give periodic dances, which are crowded with young people. The vagaries of the one-step are sternly barred by a puritan committee, and, to one who expects surprises, the style of dancing is disappointingly monotonous. But these hotels ...

(3) Give the cells a special full charging once a month. (4) Make a periodic examination of each cell, determining its E.M.F., density of acid, the condition of its plates and freedom from growth. Any incipient growth, however small, must be carefully watched. (5) If any cell shows signs of weakness, keep it off discharge till it has been brought back to full condition. ...

... Cuzco Basin Professor Gregory came to the conclusion that the Ayahuaycco gravel banks might have been repeatedly buried and reexcavated many times during the past few centuries. He found evidence indicating periodic destruction and rebuilding of some gravel terraces, "even within the past one hundred years." Accordingly there was no longer any necessity to ascribe great antiquity to the bones or the wall which we found in the Ayahuaycco quebrada. Although the "Cuzco gravels are believed to have ...

Moreover, Fernando Po shares with Senegal the undoubted yet doubtful honour of having had regular yellow fever. In 1862 and 1866 this disease ...

... to be, by no means exhausted the debt which literature owes to her during this period. It is indeed not a little curious that the productions of this time, long almost totally ignored in France itself, and even now rather grudgingly acknowledged there, are the only periodic set of productions that justify the claim, so often advanced by Frenchmen, that their country is at the head of the literary development of Europe. It was not so in the fourteenth century, when not only Chaucer in England, but Dante, Petrarch, and Boccaccio in Italy, attained ...

... steady fasting; the body accomplishes enormously more in 7 or l4 days of consecutive fasting, than 7 or 14 days of fasting accumulated sporadically, such as one day a week. This is not to say that regular short fasts are not useful medicine. Periodic day-long fasts have been incorporated into many religious traditions, and for good reason; it gives the body one day a week to rest, to be free of digestive obligations, and to catch up on garbage disposal. I heartily recommend it. But it takes many years of unfailingly regular brief ...

... office of Emperor was never more than a politico-religious concept, translated for the benefit of the masses into socio-economic ordinances.

... change of distance amounts, as already remarked, to 14,000,000 miles, which is almost half the entire distance separating the planet from the sun at perihelion. This immense variation of distance is emphasized by the rapidity with which it takes place. Mercury's periodic time, i.e., the period required for it to make a single revolution about the sun—or, in other words, the length of its year—is eighty-eight of our days. In just one half of that time, or in about six weeks, it passes from aphelion to perihelion; that is to say, in six weeks the whole ...

The first thought is that these phenomena must be due to collisions among the crowded stars, but, if so, the encounters cannot be between the stars themselves, but probably between stars and meteor swarms revolving around them. Such periodic collisions might go on for ages without the meteors being exhausted by incorporation with the stars. This explanation appears all the more probable because one would naturally expect that flocks of meteors would abound in a close aggregation of stars.
