"Oscillation" Quotes from Famous Books



... of attention is quicker than the oscillation in rivalry or fluctuation. In rivalry, each appearance may last for many seconds before giving way to the other, whereas the more typical shift of attention occurs every second or so. In fact, during a rivalry or fluctuation experiment, you may observe thoughts coming and going at the same ...

... them in to diminish their surface in reefing them. Thence the necessity of running out on foot-ropes—movable ropes stretched below the yards—of working with one hand while holding on by the other—perilous work for any one who is not used to it. The oscillation from the rolling and pitching of the ship, very much increased by the length of the lever, the flapping of the sails under a stiff breeze, have often sent a man overboard. It was then a truly dangerous operation for Tom and ...

... was formed of a single, broad and thick plank of the tulip wood. This was forty feet long, and spanned the interval between shore and shore with a slight but very perceptible arch, preventing all oscillation. From the southern extreme of the lake issued a continuation of the rivulet, which, after meandering for, perhaps, thirty yards, finally passed through the "depression" (already described) in the middle of the ...

... miracle to please us; but I unfortunately said "Oh! Mrs. Hall! it will crush your chandelier!" (one of Venice glass, very precious)—at which unbelieving remark, probably, the spirits took umbrage, for at once the table ceased ascending, and with a slow oscillation descended very gently on to the carpet. This sort of petty miracle is a frequent experience among the spiritualists, and how it is effected I cannot imagine. There could be no contrivance or machinery in our host's ...

In the 16th century may be found the conversion of rotary to reciprocating motion (strictly speaking, an oscillation through a small arc of a large circle) and vice versa by use of linkages of rigid members (figs. 3 and 4), although the conversion of rotary to reciprocating motion was at that time more frequently accomplished ...

Inured as he thought he was to the tricks of Hyperspace, to acceleration and anti-gravity, the oscillation of that swinging seat, the weird swaying of the half-recumbent figure, did things to his sight and to his sense of balance which seemed perilous in the extreme.

In the steam-line casing of the alternator the rotary spark gap, alternator, potential transformer, condenser and oscillation transformer are self-contained. Usually the alternator is mounted on the underside of the fuselage where the propeller spends its force in the form of an air stream.

... already been pointed out in previous articles, kinetic and potential energy are complementary to one another, the sum-total of the two combined always remaining the same in any cycle of work, according to the principle of the conservation of energy. We get a good example of this oscillation from kinetic to potential, and vice versa, in the planetary system. When the earth is farthest from the sun, its velocity, and consequently its kinetic energy, is at its lowest point; but there the potential energy is at its greatest. As the earth turns round in ...

... strength, for a time, is no proof of the salubrity of diet. The increased strength may not continue, though the diet should be continued. On the contrary, there is a sort of oscillation; the strength just rising, then sinking again. This is what is experienced by the trainers of boxers.

The movement at Tokio consisted of one very prominent oscillation with a total range of 73 mm. or 2.9 inches in the direction S. 70 W.; the vibrations which preceded and followed it being comparatively small. Most, if not all, of the damage caused by the earthquake must have been due to this great oscillation; ...

... Some elderly people acquire a see-saw motion of their bodies from one side to the other, as they sit, like the oscillation of a pendulum. By these motions the muscles, which preserve the perpendicularity of the body, are alternately quiescent, and exerted; and are thus less liable to fatigue or exhaustion. This therefore resembles the tremors of old people above mentioned, and not those spasmodic ...

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 oscillation ...

... According to the statements of all who have observed them, they are very destructive, though uncommon. In Lima I have often felt a kind of concussion, which accords with that term in the strictest sense of the word. This movement had nothing in common with what may be called an oscillation, a shock, or a twirl: it was a passing sensation, similar to that which is felt when a man seizes another unexpectedly by the shoulder, and shakes him; or like the vibration felt on board a ship when the anchor is ...

And, if the evils which are inseparable from the good of political liberty are to be checked, if the perpetual oscillation of nations between anarchy and despotism is to be replaced by the steady march of self-restraining freedom; it will be because men will gradually bring themselves to deal with political, as they now deal with scientifical questions; to be as ashamed of undue haste and ...

They did not know that the structure, being a suspension bridge, might have been weakened and possibly destroyed by the force of rhythmic oscillation. Yet the accumulated force in the tramp of a thousand men is no greater than that which lies in the sympathetic vibrations of a musical note. Every metal structure has its note, and it is an old engineering saw that a huge structure like ...

... not the high waves somewhat impeded her progress. Although only a moderate breeze was blowing, the sea was rough, a circumstance to be accounted for only by the diminution in the force of the earth's attraction rendering the liquid particles so buoyant, that by the mere effect of oscillation they were carried to a height that was quite unprecedented. M. Arago has fixed twenty-five or twenty-six feet as the maximum elevation ever attained by the highest waves, and his astonishment would have been very great to see them rising fifty or even sixty feet. Nor did these ...

... there has been a fluctuation in the interest on call money from 2 per cent to 30 per cent; and the fluctuation was even greater during the preceding six months. The Secretary of the Treasury had to step in and by wise action put a stop to the most violent period of oscillation. Even worse than such fluctuation is the advance in commercial rates and the uncertainty felt in the sufficiency of credit even at high rates. All commercial interests suffer during each crop period. Excessive rates for call money in New York attract money from the interior banks into the speculative ...

... 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.

But all such advances are subject to reaction and relapse. Reaction differs from relapse in this, that it is an oscillation, not a fall. Reaction is the backward swing of the wave, which will presently return, going farther forward than before. Relapse is the fall of the tide, which leaves the ships aground, and the beach uncovered. Reaction is going back to recover some ...

Two big blue dragonflies poised and quivered upon our floats, and not a fish seemed to ...

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 MacCarthy, have a different fate. In the celestial world of souls, ...

But all these move up and down, as it were, by a certain oscillation existing in the earth. And this oscillation proceeds from such natural cause as this; one of the chasms of the earth is exceedingly large, and perforated through the entire earth, and is that which Homer[43] speaks of, 'very far ...

Everywhere in Europe also this fact was corroborated, and in some places even a seventh oscillation was recorded. The Greenwich record shows that the air-waves took about thirty-six hours to travel from pole to pole, thus proving that they travelled at about the rate of ordinary sound-waves, which, roughly speaking, travel at the rate of between ...

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, in general, it is well to locate them at near the center of the porous ...

As everything in the universe is in movement, and as all the forces which are contained in matter act one against the other and counterbalance one another, all is done by a kind of oscillation; of which the mean points are those to which we refer as being the ordinary course of nature, while the extremes are the periods which deviate from that course most widely. And, as a matter of fact, with animals as much as with plants, ...

The lowness of the side-ropes, and the oscillation of the ricketty structure rendered the feat altogether a rather more amusing performance to the looker on than to the actual performer, and I was not to reach the opposite shore.

... God is lord of all things: he must be all things and the soul in its endeavour to reach God must obtain deliverance from the fetters not only of matter but of individuality. Hence Hindu theology is in a perpetual oscillation illustrated by the discrepant statements found side by side in the Bhagavad-gita and other works. Indian temperament and Indian logic want a pantheistic God and a soul which can transcend personality, but religious thought and practice imply personality both in the soul and in God.

As yet, however, we have no certain knowledge as to whether changes in the periods at which the stream becomes visible, or the 'retardations' of the phenomena of which I have already spoken, indicate a regular precession of oscillation of the nodes — that is to say, of the points of intersection of the Earth's orbit and of that of the ring; or whether this ring or zone attains so considerable a degree of breadth from the irregular ...
