"Acceleration" Quotes from Famous Books



... depth and chord to take my Spars and Ribs, and again, I must have a certain chord to make it possible for my Camber (that's curvature) to be just right for the Angle of Incidence. If that's not right the air won't get a nice uniform compression and downward acceleration from my underside, and the rarefied 'suction' area over the top of me will not be as even and clean in effect as it might be. That would spoil the Lift-Drift Ratio more than you can help it. Just thrust that chalk along, will ...

... This staircase, consisting of three hundred and sixty steps, extends downward to a similar depth of eighty-five feet, and forms a sort of well, at the bottom of which you can perceive the light. From this well have been observed the different degrees of acceleration in the ...

... rate of 42 miles per hour; an unprecedented speed in those days. People then thought themselves most heroic in entrusting their lives to a train that travelled with such terrific velocity as the "Wild Irishman." It was to meet this acceleration that Mr. Ramsbottom, the Locomotive Superintendent of the London and North-Western Railway, devised a scheme for laying water-troughs between the rails, by which the engine could pick up water through a scoop whilst running. I have somewhere seen this claimed as an American innovation, ...

... the confession on his lips which would otherwise never have escaped them. Thence came the discovery which had sent him home to summon the lawyer to the house. That summons, again, had produced the inevitable acceleration of the Saturday's journey to Friday; the Friday of the fatal accident, the Friday when he went to his death. From his death followed the second bereavement which had made the house desolate; the helpless position of the daughters whose prosperous future had been his dearest ...

... there is an ebb and flow of power in our internal mechanism, corresponding to the phases of the moon. I mean, that the blood flows more rapidly, and the powers of nature are more stimulated, at the flood and full, than at the ebb and neap, when a reaction takes place in proportion to the previous acceleration. Dr Mead has observed, that of those who are at the point of death, nine out of ten quit this world at the ebb of the tide. Does not this observation suggest the idea, that nature has relaxed her efforts during that period, after ...

... peculiarity of truly human life is that man has to create himself by his own voluntary efforts; he has to make himself a truly moral, rational, and free being. This creative effort is carried on by the educational activities of slow generations. Its acceleration depends upon men consciously striving to educate their successors not for the existing state of affairs but so as to make possible a future better humanity. But there is the great difficulty. Each generation is inclined to educate its young ...

... satellite follow its orbit to the world's end, or would its supply of radium soon exhaust itself after so many eons of time, converting the rocket into the prey of the first large meteor which chanced that way? Would it some day return to the earth as its nearer approach portended, and increase its acceleration in a long arc to crash upon the surface of the dead planet? And when the rocket terminated its career, would the body of Professor Jameson be found perfectly preserved or merely a ...

... appreciably quickened; by either of which means nature would be enabled to make up the deficiency. It is true that it is difficult to count one's own respirations, but the average is considered in a healthy man to be eighteen in a minute; in my own case it is sixteen, an acceleration of which by three or four could not have been overlooked, in the repeated trials I made at Dorjiling, and still less the eight additional inhalations required at 15,000 feet to make up for the deficiency of oxygen in the ...

... They were perfectly wild that day. When Lassesen, for instance, caught sight of his enemy Hans, who was in another team, he immediately encouraged his friend Fix to help him. These two then put on all the speed they could, with the result that the others in the same team were excited by the sudden acceleration, and joined in the spurt. It made no difference how the driver tried to stop them; they went on just as furiously, until they reached the team that included the object of Lassesen's and Fix's endeavours. Then the two teams dashed into each other, and we had ninety-six dogs' legs to sort out. The ...

... crop of romancers who have followed the leadership of Dumas. There has, indeed, been a great and inspiriting revival of romance in our time, but it is partly frustrated in almost every case by this rooted conception that romance consists in the vast multiplication of incidents and the violent acceleration of narrative. The heroes of Mr Stanley Weyman scarcely ever have their swords out of their hands; the deeper presence of romance is far better felt when the sword is at the hip ready for innumerable adventures too terrible to be pictured. The Stanley ...

... from utilising, as a point of arrival and departure, that almost mid-Atlantic outpost of the younger world, Newfoundland—or at the least Nova Scotia. By this means the actual waterway between the two continents will be shortened by something like a third. What with the acceleration of the ferry-boats and the narrowing of the ferry, it is surely no visionary Jules-Vernism to look forward to the time when one may set foot on American soil, within, say, sixty-five hours of leaving the Liverpool landing-stage; supposing, ...

... though no doubt slowly, diminishing. The change thus produced is not appreciable when only small intervals of time are considered, but it becomes appreciable when we have to deal with intervals of thousands of years. The actual effect which is produced by the lunar acceleration, for so this phenomenon is called, may be thus estimated. If we suppose that the moon had, throughout the ages, revolved around the earth in precisely the same periodic time which it has at present, and if from this assumption we calculate ...

... even a gig, if properly constructed, admits of the driver having a certain amount of control over his horse; he is well above the animal, and can get a good purchase to pull him up from, when the acceleration is becoming dangerous, or there is a tendency to the grosser insubordination of a "kicking match." Not so in a pony-carriage: low down upon the ground, even under their very heels, you are completely at the mercy of your team; and the facility of egress in ...

Railways and rapid steamboats enable coin and bullion to be more swiftly remitted than of old; telegraphs prevent its needless removal, and the acceleration of the mails has a like effect."

... and rising some three hundred feet into the air at night—just high enough, in fact, to take them over and clear of the masts of any ships that they might happen to encounter during the hours of darkness—maintaining a tolerably uniform speed of ten knots through the air—not counting the acceleration or retardation of speed due to the varying direction and strength of the several winds that they met with. Thus they had been able to sleep at night with wide open ports, to their great comfort and enjoyment, and the manifest improvement of their health, as was particularly exemplified ...

According to program, acceleration will begin at zero, and the rim is expected to reach .009 gee at one-half revolutions per minute in the first sixty seconds of operation. We will hold that spin until balance is complete, when the spin will slowly be raised to two revolutions per minute, ...

... and to introduce market mechanisms into the economy. Despite substantial progress toward macroeconomic adjustment, in 1992 the reform drive stalled as Algiers became embroiled in political turmoil. In September 1993, a new government was formed, and one priority was the resumption and acceleration of the structural adjustment process. Buffeted by the slump in world oil prices and burdened with a heavy foreign debt, Algiers concluded a one-year standby arrangement with the ...

... undoubtedly a far more ready, and we have long thought a finer player than Steinitz, but skill was so nicely balanced between them that a very slight variation or acceleration in rate would have been in Zukertort's favour. At 25 moves an hour or at any faster rate it would have been odds on Zukertort, at 15 moves an hour or less it would have been safer to back Steinitz. Staunton, Kolisch, and Paulsen seem to have been the ...

In all vibrations and undulations there is a going and returning, between which must exist minute periods of repose; but in many instances the return is simply a relaxation or a subsidence, ...

... manifested certain fears about the moon; they had heard that since the observations made in the times of the Caliphs her movement of revolution had accelerated in a certain proportion; they thence very logically concluded that an acceleration of movement must correspond to a diminution in the distance between the two bodies, and that this double effect going on infinitely the moon would one day end by falling into the earth. However, they were obliged to reassure themselves and cease to fear for future generations when they were ...

Freddy Dickson, an earnest, anemic youth, seemed to be always striving for greater acceleration and never gaining it; or as Pudge put it, "The trouble with Freddy is that he's always shifting gears."

... eighteenth century, which directly concerns us, because the religious superstition, which had previously caused men to seek in a conscious supreme energy the effective motor in human affairs, had waned, and the problem presented was reduced to the operation of that acceleration of movement by the progress of applied science which always has been, and always must be, the prime cause of the quickening of economic competition either as between communities or as between individuals. And this is the capital phenomenon of civilization. For it is now generally admitted ...

... Miss Anvoy. I forget to-day the exact order in which, at this period, sundry incidents occurred and the particular stage at which it suddenly struck me, making me catch my breath a little, that the progression, the acceleration, was for all the world that of fine drama. This was probably rather late in the day, and the exact order doesn't signify. What had already occurred was some accident determining a more patient wait. George Gravener, ...

... causes these forces to operate with an energy inversely proportionate, not to the distance, but to its square. We had no reason to think that apergy, exempt as it is from this law, would be at all diminished by distance; and this view the rate of acceleration as I rose from the Earth had confirmed, and my entire experience has satisfied me that it is correct. None of our experiments, however, had indicated, or could well indicate, at what rate this force can travel through space; nor had I yet ...

... together in given relations, begin to work toward a logical issue; but the individual chapters stand before us rather as isolated pictures, with intervals between, than as the closely conjoined links of a drama gathering momentum as it grows. There is succession and acceleration, indeed, in the movement of the story, but this is not quite so evident as is the hand which checks each portion and holds it perfectly still, long enough to describe it completely. The author does not, like a playwright, reflect the action swiftly while it passes, but rather arrests it ...
