"Trajectory" Quotes from Famous Books



... Europe after the fall of Rome, and the generation of those vital forces that for two centuries were to infuse society with a vigour almost unexampled in its potency and in the things it brought to pass. The parabolic curve that describes the trajectory of Mediaevalism was then emergent out of "chaos and old night" and Abelard and his opponent, St. Bernard, rode high on the mounting force in its swift and almost ...

... or, in other words, it could 'be' there. It would 'be' there if it stopped there, but, if it stopped there, it is no longer the same movement with which we are dealing. It is always at one bound that a trajectory is traversed when, on its course, there is no stoppage. The bound may last a few seconds, or it may last for weeks, months, or years, but it is unique and cannot be decomposed. Only, when once the passage has been made, as the path is in space, and space is infinitely divisible, we picture ...

... heavy rain that was accompanied by thunder—or indications of disturbance aloft—but by no visible lightning. The sea is close to Hindon, but if you try to think of these fishes having described a trajectory in a whirlwind from the ocean, consider this ...

... other navigational terminology, plus nonsensical chatter of probability factors. The picture faded and was replaced with an artist's animated conception of the impending tragedy. It showed the present location of the ship, the calculated course and trajectory of the ship through the atmosphere to the point of impact—right in the center of the industrial area. It ended with a big question mark before the image of the ...

... the wall of the shed and went through it like paper, smashed into a stud and caromed slightly, so that its trajectory was altered enough to drive it directly at Rick. He fell flat and it went over, just grazing him, then flew into the palm grove. It hit a palm a slanting blow and turned upward, shooting high in the air, clipping off the top of another palm ...
— The Wailing Octopus • Harold Leland Goodwin

... adopted the opinion that the human race is in a state of necessary progression. The reciprocal action between circumstances and human nature, from which social phenomena result, must produce either a cycle or a trajectory. While Vico maintained the conception of periodic cycles, his successors have universally adopted the idea of a trajectory or progress, and are endeavouring to discover its law. [Footnote: Philosophical writers in England in the middle of the ...

... better view of our position, accompanied only by an orderly; then, lying down and resting the express on a rock, I covered him. The rifle, like all expresses, was only sighted to three hundred and fifty yards, so to allow for the drop in trajectory I took him half-way down the neck, which ought, I calculated, to find him in the chest. He stood quite still and gave me every opportunity, but whether it was the excitement or the wind, or the ...

... the solid line behind the zeriba was an easy target. The artillery now began to clear out these depressions by their shells, and in this work they displayed a searching power very remarkable when their flat trajectory is remembered. As the shells burst accurately above the Dervish skirmishers and spearmen who were taking refuge in the folds of the plain, they rose by hundreds and by fifties to fly. Instantly the hungry and attentive Maxims and the watchful infantry opened on ...

... this small particle, completed. Always, however, is exerted the gravitational pull of matter, and the energy that drove through, instead of pursuing a right line, tends to bend in a parabolic curve, like the trajectory of a cannon ball. In the completion of the process some portion of redeemed matter "gets by," so to speak, but other portions do not; they return to their source of origin and are reabsorbed in matter, becoming subject to the ...

... at all games, especially la balle au camp. I used to envy the graceful, easy way he threw the ball—so quick and straight it seemed to have no curve at all in its trajectory: and how it bounded off the boy it nearly ...

... the fire of a machine gun the more effective it is. This causes the principal employment of the machine gun to be at distances where the trajectory is flattest, that is under 800 or 1,000 yards. However, the effort to obtain a grazing fire must not exclude long distance fire. This latter will always be justified when directed upon important objectives, or necessary ...

... splendid fellow, his second in command, named Berwkoff, who was greatly loved by us all. A Magyar soldier seeing Kalmakoff with his Ataman banner borne by his side, took a point-blank shot at his head, but he forgot the high trajectory of the old Russian rifle, and the bullet merely grazed the top of the Cossack leader's head and sent his papaha into the mud. His banner-bearer could not see his leader's cap so left, and jumped off his ...

... buildings on which the Geneva Cross was flying. These are, unfortunately, just in the line of "Long Tom's" fire from Rietfontein Hill, and the shells may have been aimed at our naval battery, but, if so, they went very high, or their trajectory at that range would not have carried them half a mile ...

... B, with an interval of rest. A single movement is entirely, by the hypothesis, a movement between two stops; if there are intermediate stops, it is no longer a single movement. At bottom, the illusion arises from this, that the movement, once effected, has laid along its course a motionless trajectory on which we can count as many immobilities as we will. From this we conclude that the movement, whilst being effected, lays at each instant beneath it a position with which it coincides. We do not see that the trajectory ...

... passed close by me, evoking all the more forcibly her whom it labelled in that it did not merely refer to her, as one speaks of a man in his absence, but was directly addressed to her; it passed thus close by me, in action, so to speak, with a force that increased with the curve of its trajectory and as it drew near to its target;—carrying in its wake, I could feel, the knowledge, the impression of her to whom it was addressed that belonged not to me but to the friend who called to her, everything that, while she uttered the ...

... Under these circumstances, the enemy, although he could no longer see it, reached it by a curved or "plunging" shot. When, in fact, for a given distance we load a gun with the heaviest charge that it will stand, the trajectory, AMB (Fig. 2), is as depressed as possible, and the angles, a and a', at the start and arrival are small, and we have a direct shot. If we raise the chase of the piece, the projectile will describe a curve in space which would ...

... silver glare swept the forward deck, clean white and splashed with black shadows. We had partly circled the Moon, so as now to approach it from the Earthward side. I had worked with extreme concentration through the last few hours, plotting the trajectory of our curving sweep, setting the gravity plates with constantly shifting combinations. And with it a necessity for the steady retarding ...
