"Rotatory" Quotes from Famous Books



... fields, and the town— To plough, loom, anvil, spade—and oh! most sad To that dry drudgery at the desk's dead wood? Who but the Being unblest, alien from good, Sabbathless Satan! he who his unglad Task ever plies 'mid rotatory burnings, That round and round incalculably reel— For wrath divine hath made him like a wheel— In that red realm from which are no returnings; Where toiling, and turmoiling, ever and aye He, and his ...

... theory of his own which was no better, namely, that the Corona was due to the existence of an atmosphere round the Moon and proved its existence. From this time forwards we have statements, by various observers, applying to various eclipses, of the Corona seeming to be endued with a rotatory motion. The Spanish observer, Don A. Ulloa, in 1778, wrote thus respecting the Corona seen in that year:—"After the immersion we began to observe round the Moon a very brilliant circle of light which seemed to have a rapid circular motion something similar to that of a ...

... begins with a small capital as a money-changer, soon buys a share in a broker's business; and, to go even lower, a petty clerk becomes a notary, a rag-picker lays by two or three thousand francs a year, and the poorest workmen often become manufacturers; whereas, in the rotatory movement of this present civilization, which mistakes perpetual division and redivision for progress, an unhappy civil service clerk, like Chazelle for instance, is forced to dine for twenty-two sous a meal, struggles with his tailor ...

... revolutions, and its motions are annual, rotatory and diurnal, in all its extensive diversity of waiters, cooks, saucepans, fryingpans, gridirons, salamanders, stoves and smoke-jacks; so that if you wish to know true and uncloying delight, you are now acquainted with where it is to be found. Not all ...

... things of price. Trash, in the fullness of its insimplicity and cheapness, is impossible without a beautiful past. Its chief characteristic—which is futility, not failure—could not be achieved but by the long abuse, the rotatory reproduction, the quotidian disgrace, of the utterances of Art, especially the utterance by words. Gaiety, vigour, vitality, the organic quality, purity, simplicity, precision—all these are among the antecedents of trash. It is after them; it is also, alas, because ...

... gravitation, the process of an aggregation of the neighbouring matter to those nuclei should proceed, until masses more or less solid should become detached from the rest. It is a well-known law in physics that, when fluid matter collects towards or meets in a centre, it establishes a rotatory motion. See minor results of this law in the whirlwind and the whirlpool—nay, on so humble a scale as the water sinking through the aperture of a funnel. It thus becomes certain that when we arrive ...

... as on the Zanzibar coast, according to Stecker (quoted by Ploss-Bartels, Das Weib, Section 119) young girls are educated in buttock movements which increase their charm in coitus. These movements, of a rotatory character, are called Duk-Duk. To be ignorant of Duk-Duk is a great disgrace to a girl. Among the Swahili women of Zanzibar, indeed, a complete artistic system of hip-movements is cultivated, to be displayed in coitus. It prevails more especially ...

... coloured clay) is put into a large calabash, and mixed with a sufficient quantity of water. The woman, whose office it is, then shakes the calabash in such a manner, as to mix the sand and water together, and give the whole a rotatory motion; at first gently, but afterwards more quick, until a small portion of sand and water, at every revolution, flies over the brim of the calabash. The sand thus separated is only the coarsest particles mixed with a little ...

... done. So they helped. They took turns gripping the pipe while Jonathan and I persuaded the young tree through it. It required great strength and some skill because it was necessary to make the tree and the pipe perform spirally rotatory movements each antagonistic and complementary to the other. We were all rather tired and very hot before anything began to happen. Then it happened all at once: the tree burst through—and not alone. A good deal came ...

... disadvantage; if a gust of wind struck it, the balloon was blown downward and down wind, generally twirling in the air and upsetting any calculations and estimates that might be made by the observers, while in a wind of 25 miles an hour it could not rise at all. The rotatory movement caused by wind was stopped by an experimenter in the Russo-Japanese war, who fixed to the captive observation balloons a fin which acted as a rudder. This did not stop the balloon from being blown downward and away from its mooring station, but this tendency was overcome ...

... with a grosser faith, as our senses give it us. We behold space sown with rotatory islands, suns and worlds and the shards and wrecks of systems: some, like the sun, still blazing; some rotting, like the earth; others, like the moon, stable in desolation. All of these we take to be made of something we call matter: a thing which no analysis can help us to conceive; to whose incredible ...

... this, that it will fly up as easily as a ball when it is laid in the trap, for the striker has only to tap one end of it, and up it flies, making many a summerset as it rises; while it is performing this turn-over motion, which philosophers call the rotatory, the striker makes a blow at it and sends ...

... be—that suit bearing in its suite a long line of substantial breakfasts, dinners, and suppers. All this was about to be Mr Pigtop's, our kind messmate, and respectable mate of the orlop deck. He had already begun to protest upon the unreasonableness of rotatory coats, or of having a quarter-deck pair of trousers, like the wives of the ancient Britons, common to the sept. The ungrateful rogue! He had on, at the very time, the only quarter-deck-going coat among us, which was mine, and which he had just borrowed to enable him to go on deck, ...

... can trace the law of periodicity we are strongly impressed with the idea of rotatory or orbitual motion.

Thither Peter went, and in lieu of his lace-bedaubed coat, gold-gartered plushes, stockings, and buckled ...

... they consisted would become liquid or solid. The known law of gravitation would then cause them to agglomerate in masses, which would assume the shape our planets actually exhibit; would acquire, each round its own axis, a rotatory movement; and would in that state revolve, as the planets actually do, about the sun, in the same direction with the sun's rotation, but with less velocity, and each of them in the same periodic time which the sun's rotation occupied when his atmosphere extended ...

... in this step; but you can vary the movement by going backwards or forwards at pleasure, instead of continuing the rotatory motion. The Valse a Deux Temps, like the Polka, admits of a reverse step; but it is difficult, and looks awkward unless executed to perfection. The first requisite in this Valse is to avoid all jumping movements. The ...

... and adventure. I become insupportably wearied with the repetition of rotatory acts and every-day occurrences. I want to be alive, to be something more than I commonly am, to change the scene, to cut the cable that binds my bark to the shore, to launch into the wide sea of possibilities, and to nourish my thoughts with observing a train of ...

... were inside the boiler, within which the single cylinder, eight inches in diameter and four feet six inches stroke, was placed horizontally. As in the first engine, the motion of the wheels was produced by spur gear, to which was also added a fly-wheel on one side, to secure a rotatory motion in the crank at the end of each stroke of the piston in the single cylinder. The waste steam was thrown into the chimney through a tube inserted into it at right angles; but it will be obvious that this arrangement was not calculated to produce any result in the way of a steam-blast ...

... the effect of the friction of the earth's surface on the eastward circulation of the air by a very simple experiment with a pail of water. If we put into the pail grains of any material a little heavier than water, and then give the water a rotatory motion by stirring it, the grains ought, by the centrifugal force imparted to them, to collect around the sides of the pail; but, sinking to the bottom, they do in fact tend to collect at the centre, carried ...

... behind it. This appears to be the true explanation of the phenomenon. [Footnote: Popular Science Review, 1871, p. 307.] These belts are probably due to vast masses of steam, poured forth with great force from the body of the planet. As the atmosphere of Jupiter is probably of enormous depth, the rotatory velocity of its upper portions would be much greater than that of the surface of the planet, hence the steam would arrange itself in belts parallel to the equator of the planet. But this view leads us to wonderful conclusions with reference to the ...

... some of these objects were noticed by him. The remarkable form of one sketched at Wateringbury, in Kent, January 17, 1852, gave him the means of detecting and measuring a rotatory movement of the whole spot round the black nucleus at the rate of 100 degrees in six days. "It appeared," he said, "as if some prodigious ascending force of a whirlwind character, in bursting through the cloudy stratum and the two higher and luminous strata, had given ...

... and, changing his seat to one nearer the fire, began to examine the other guests with an eye to the delights of oratory. There were near a dozen present, all men, and (as Joseph exulted to perceive) all working men. Often already had he seen cause to bless that appetite for disconnected fact and rotatory argument which is so marked a character of the mechanic. But even an audience of working men has to be courted, and there was no man more deeply versed in the necessary arts than Joseph Finsbury. He placed his glasses on his nose, ...

... and which give to the tree the odd name of "volador," or "flier." These seeds have each a pair of membranaceous and striated wings, which, when the seeds fall, are turned to meet the air at an angle of 45 deg.; and thus a rotatory motion is produced, and the falling seeds turn round and round like little fly-wheels. It is altogether a curious sight when a large volador is shaken in calm weather, to see the hundreds of seeds whirling and wheeling towards the ground, which they take a considerable time in reaching. The ...

... had seen and enjoyed everything that the plate recalled to me, and had beheld with admiration how the rotatory motion which keeps this ball of ours in its place in the great scheme, with all its busy mites upon it, was necessary throughout the process, and could only be dispensed with in the fire. So, listening to the plate's reminders, and musing ...

... inches long and two thick, diminished from the middle to form a double cone. When the cat is placed on the ground, the player strikes it smartly—it matters not at which end—and it will rise with a rotatory motion high enough for him to strike it; if he misses, another player takes his place; if he hits, he calls for a number to be scored to his game; if that number is more than as many lengths of his cudgel, he is out; if not, they are scored, ...

... will insist upon going round the pole in one direction, and you cannot persuade it to go the other. These circular movements seem almost to resemble those of the planets about their centre, all things down to the ether seem to have a rotatory motion; and some foreign plants which he grew send their far-extended tendrils round and round with so patent a movement that you can see it hour by hour like the hand of a clock. Perhaps the little book on earthworms is a yet more wonderful achievement of this great genius, who had not only ...
