"Acceleration" Quotes from Famous Books



... make us miserable if they remain unfulfilled. It is the change, and not the possession, which has the emotional value. The up and down, the forward and backward, are felt in the social world, just as in the world of space the steady movement is not felt, but only the retardation or the acceleration. ...

... rapidly. At first it had been slow, but later a sudden acceleration had manifested itself. This began from the moment Madeline tried on the white-satin slippers, and in so doing found herself. The pride of her renegade father, apart from any natural self-esteem she might possess, at that ...

... were deactivated, hundreds of gyros swung the mile-long ship end for end and stabilized her on a reverse course, drive units big enough to power several major cities whined into operation, anti-grav generators with the strength to shift small planets counterbalanced the external acceleration, and the ship moved, away, with a speed approaching ...

... was one of the engineers on the rocket-sled experiments that were done by the U.S. Air Force in 1949 to test human acceleration tolerances (USAF project MX981). One experiment involved a set of 16 accelerometers mounted to different parts of the subject's body. There were two ways each sensor could be glued to its mount, and somebody methodically installed all 16 the wrong way around. Murphy then made the original form ...

... solve problems with two variables. On the Newtonian theory, for instance, acceleration varies with distance, but distance also varies with acceleration. In the realm of truth- processes facts come independently and determine our beliefs provisionally. But these beliefs make us act, and as ...

... Empire; though it must be admitted that the Gallipoli episode proved that the Turk still possesses a 'notable horn' of strength. Historically speaking, this drying up of Ottoman power has been going on for the past century; the last two years have witnessed a great acceleration of the process, and there can be no doubt that ...

... allusion was made by the PRIME MINISTER—is so vast that the joint efforts of Sir DONALD MACLEAN and Mr. ADAMSON to fill it met with only partial success. Unless, by the way, Mr. SPEAKER definitely decides the problem of precedence, it is to be feared that the hoped-for acceleration of business will not occur, for at present each of them thinks it necessary to speak whenever the other does, like the hungry lions on Afric's burning shore. For all their outward politeness I am sure "the first lion thinks the last a bore"; and if they insist on roaring together ...

... cylinders in engines of this type is produced by the side pressure of the pistons on the cylinder walls, and in order to prevent this pressure from becoming abnormally large it is necessary to keep the weight of the piston as low as possible, as the pressure is produced by the tangential acceleration and retardation of the piston. On the upward stroke the circumferential velocity of the piston is rapidly increased, which causes it to exert a considerable tangential pressure on the side of the cylinder, and ...

... cell and of the organism in general,[1] we find a similar attitude towards external sources of available energy. In the act of growth increased rate of assimilation is involved, so that there is an acceleration of change till a bulk of maximum activity is attained. The surface, finally, becomes too small for the absorption of energy adequate to sustain further increase of mass (Spencer[2]), and the acceleration ceases. The waste going on in the central ...

... industry which has prevailed since the middle of the eighteenth century as machine-production, not because there were no machines before that time, but firstly, because a vast acceleration in the invention of complex machinery applied to almost all industrial arts dates from that period, and secondly, because the application upon an extensive scale of non-human motor powers manifested itself then for ...

... average 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 ...

... there was no water for five miles, he resolved to halt for the day and rest. Hosh-el-Geref was therefore not reached until the 1st of August—a day later than had been expected; but the rest had proved of such benefit to the troops that the subsequent acceleration of progress fully compensated for the delay. The column moved on again at midnight and halted at daybreak at Salmi. In the small hours of the next morning the march was resumed. The road by the Nile was found too difficult for the Maxim guns, ...

He remarked domination. He altered acceptation. He changed selection. He persisted in continuation. He achieved ...

... come about in less than a century; most of them in a quarter of a century. Multiply them by the years of another century, and who shall say that the events I depict are impossible? There is an acceleration of movement in human affairs even as there is in the operations of gravity. The dead missile out of space at last blazes, and the very air takes fire. The masses grow more intelligent as they grow more wretched; and more capable of cooperation as they ...

... two other men in the seminar. 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."

Thus they had been able to sleep at night with wide open ports, to their great comfort and enjoyment, and the manifest ...

After this, events came in quick succession. The Agpuris were driven first from their various positions outside the city walls, ...
