"Oscillation" Quotes from Famous Books



... various objects contained in dwellings; but it was generally admitted that these did not proceed from earthquake shocks, but from atmospheric vibrations. No deviation of the magnetic needle was observed at the Meteorological Institute of Batavia; but a vertical oscillation was apparent, and persons who listened with the ear placed on the ground, even during the most violent detonations, could hear no subterranean noise whatever. It became clear that the sounds came from some volcano burst into activity; but it is strange that for two whole days ...

... lost. Olivari, who perished at Orleans, rose in a paper 'Montgolfier;' his car, suspended below the chafing-dish, and ballasted with combustible materials, caught fire; Olivari fell, and was killed! Mosment rose, at Lille, on a light tray; an oscillation disturbed his equilibrium; Mosment fell, and was killed! Bittorf, at Mannheim, saw his balloon catch fire in the air; and he, too, fell, and was killed! Harris rose in a badly constructed balloon, the valve of which was too large and would not shut; Harris fell, and ...

... fall! At one place, the way is upon long beams introduced into holes made in the rock, like a bridge, and covered up with earth. Brr!—At the thought that a little stone might get loose and roll down the slope of the mountain, or that a too strong oscillation of the beams could precipitate the whole structure into the abyss, and with it him who had ventured upon the perilous path, one feels like fainting more than once during ...

... on as he was that they relapsed, and really for so long a time that the day inevitably came for a further sounding of their depths. These depths, constantly bridged over by a structure firm enough in spite of its lightness and of its occasional oscillation in the somewhat vertiginous air, invited on occasion, in the interest of their nerves, a dropping of the plummet and a measurement of the abyss. A difference had been made moreover, once for all, by the fact that she had ...

... view, life appears in its entirety as an immense wave which, starting from a centre, spreads outwards, and which on almost the whole of its circumference is stopped and converted into oscillation: at one single point the obstacle has been forced, the impulsion has passed freely. It is this freedom that the human form registers. Everywhere but in man, consciousness has had to come to a stand; in man alone it has kept on its way. Man, then, continues the ...

... remains always an idea that reality can never completely reach. In reality, there will always remain a preponderance of one of these elements over the other, and the highest point to which experience can reach will consist in an oscillation between two principles, when sometimes reality and at others form will have the advantage. Ideal beauty is therefore eternally one and indivisible, because there can only be one single equilibrium; on the contrary, experimental beauty will be eternally double, because in the ...

... and swearing. She heard Marsac at the door talking to Noko in French and the woman answering him. Her heart beat so that it well-nigh strangled her. But he did not come in. Presently the rumbling and unloading were over, and there was no sound but the oscillation of the vessel as it floundered in the tide with short beats, until the turning, and then the motion grew more endurable. If she could only see! But from her window there was nothing save an expanse ...

... the heads of the pistons, after the Gnome pattern, the exhaust valves being in the heads of the cylinders. The inlet valve in the crown of each piston was mechanically operated in a very ingenious manner by the oscillation of the connecting-rod. The Gyro-Duplex engine superseded this original design, and a small cross-section illustration of this is appended. It is constructed in seven and nine-cylinder sizes, with a power ...

... I say, though you can see nothing. You can see and hear the spark indeed—but that is a mere secondary disturbance we can for the present ignore—I do not mean any secondary disturbance. I mean the true ethereal waves emitted by the electric oscillation going on in the neighborhood of this recoiling dielectric. You pull aside the prong of a tuning fork and let it go; vibration follows and sound is produced. You charge a Leyden jar and let it discharge; vibration ...

... protection and in accordance with a Roman custom lately introduced into Carthage, a man was fastened by the waist to a long chain let into the wall. His beard and nails had grown to an immoderate length, and he swayed himself from right to left with that continual oscillation which is characteristic of captive animals. As soon as he recognised Hamilcar he ...

... upon these winter months, Piers could distinguish nothing clearly. It was a time of confused and obscure motives, of oscillation, of dreary conflict, of dull suffering.

... its upheaval. The Red Sea, therefore, is the only area in which we have clear proofs of the recent elevation of a district, which, by our theory (although the barrier-reefs are there not well characterised), has lately subsided. But we have no reason to be surprised at oscillation, of level of this kind having occasionally taken place. There can be scarcely any doubt that Savage, Aurora (Aurora Island is described by Mr. Couthouy ("Remarks," page 58); it lies 120 miles north-east of Tahiti; it is not coloured in the appended map, because it does not appear to be ...

... be clear. The powerful engine called Rochdale (No. 247 on the company's register) was attached to two carriages, with a guard's van behind. The first carriage was solely for the purpose of decreasing the inconvenience arising from the oscillation. The second was divided, as usual, into four compartments, a first-class, a first-class smoking, a second-class, and a second-class smoking. The first compartment, which was nearest to the engine, was the one allotted to the travellers. The other three were empty. The ...

... The length of this aerial bridge, sometimes exceeding two hundred feet, caused it, confined, as it was, only at the extremities, to dip with an alarming inclination towards the centre, while the motion given to it by the passenger occasioned an oscillation still more frightful, as his eye wandered over the dark abyss of waters that foamed and tumbled many a fathom beneath. Yet these light and fragile fabrics were crossed without fear by the Peruvians, and are still retained by the Spaniards ...

... the extremely high pressure of lightning discharges, their high frequency of oscillation would enable ordinary coils to be self-protecting against them. But a discharge of electricity can take place through the air or other insulating medium if its pressure be high enough. A pressure of 70,000 volts can strike across a gap in air of one inch, and lower pressures ...

... to every call, solicited by every impulse, yet still, like the magnet, vibrate ever to the north, never so tense, never so aware of the stress and strain of force as when most irremovably fixed upon that goal. The intensity of life is not to be measured by the degree of oscillation. It is at the stillest point that the most tremendous energies meet; and such a point is the intelligence open to infinity. For such stillness I feel myself to be destined, if ever I could attain it. But others, I suppose, like ...

... consonant with some of the facts given), that domestication in certain animals induces and occasions a capacity for change which is wanting in wild animals—the introduction of new causes occasioning new effects. For, though a certain degree of variability (normally, in all probability, only oscillation) exists in all organisms, yet domestic ones are exposed to new and different causes of variability, resulting in such striking divergencies as have been observed. Not even in this latter case, however, ...

... corked porous vessel that carries a glass tube, c, which dips into a vessel containing either water or methylic alcohol. Three or four gas jets, one of which is shown at E, are arranged around the porous vessel, as close as possible, but in such a way as not to touch it during the oscillation of the beam. These gas jets communicate with a gasometer tilled with hydrogen, the bell of which is so charged as to furnish a jet of sufficient strength. Experience will indicate the best place to give the gas jets, but, ...

... their distances inversely. That the centrifugal forces result from the same pressure or impulse,—that the varied densities of the opposite sides of the masses, as land and water, occasion a uniform external pressure to produce rotation on an axis,—that the action or oscillation of the fluid surfaces, a consequence of the rotation, constantly changes the mechanical centre of the mass, so as thereby to drive forward the mathematical centre in an orbit,—and that this is the purpose and effect of the tides, increased ...
