"Trajectory" Quotes from Famous Books
 ... contained in embryo within an equation, the mysterious nut which must be artistically cracked to extract the rich kernel, the theorem! Take this or that term, place the sign before it and forthwith you have the ellipse, the trajectory of the planets, with its two friendly foci, transmitting pairs of vectors whose sum is constant; substitute the—sign and you have the hyperbola with the antagonistic foci, the desperate curve that dives into space with infinite tentacles, ...

... glance around. It was a metallic cubby, not much over fifteen feet square, with an eight-foot arched ceiling. There were instrument panels. The range-finder for the giant projector was here; its little telescope with the trajectory apparatus and the firing switch were unmistakable. And the signalling apparatus was here! Not a Martian set, but a fully powerful Botz ultra-violet helio sender with its attendant receiving mirrors. The Planetara ...

... adjusted for a maximum range of 200 yards. Although at this distance considerable accuracy could be attained at the target upon a quiet day, it was difficult to shoot with any precision at an unmeasured range owing to the high trajectory of the bullet. Thus for sporting purposes it was absolutely essential that the hunter should be a first-rate judge of distance in order to adjust the sights as required by the occasion. It was accordingly rare to meet ...
— Wild Beasts and their Ways • Sir Samuel W. Baker
... Its rounded bow had pointed longingly at the stars. Now it tilted downward. Its direction of movement did not change, of course. In the absence of air, it could tumble indefinitely without any ill effect. It was in a trajectory instead of on a course, though presently the trajectory would become an orbit. But it pointed nose-down toward the Earth even as it continued to ...

... 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 fact of the man being a long shot, I don't know, but this was what happened. Getting dead on, as I thought, ...

... and letting fly at a clump of the little men, which scattered like a covey of partridges, leaving one of its number kicking on the ground. "Ah! my boy," shouted Jeekie in derision, "how you like bullet in tummy? You not know Paradox guaranteed flat trajectory 250 yard. You remember that next time, sonny." Then off they went again ...

... learn the elevation or trajectory at which his arrows fly at various distances. Shooting in the woods over hanging limbs may interfere with a good shot. In this case the archer can kneel and thus lower his flight ...

... direction and precision of range. All modern guns are capable of being made to shoot straight; but their precision of range depends partly on the successful designing of the gun and ammunition, so as to give uniform velocities, and partly on the flatness of the trajectory. The greater the velocity, the lower the trajectory, and the greater the chance of striking the target. Supposing a heavy gun to be mounted as in the fortresses round our coasts, and aimed with due care, the distance of the object being approximately known, we may fairly ...

... grazing 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 points of passage. For this fire to have some ...

... hovering there, he watched the flight of that silvery plane speeding straight toward the executive mansion while all around it the shells bloomed and spread. It was over the White House grounds. The archies had failed; they were being outmaneuvered, they could not be swung in time to follow the trajectory of the plane. Dick ...

Mr. Kephart goes at some length into the questions of range, trajectory and killing power of the different types of rifles and charges and also has chapters on rifle mechanisms, sights, barrels, and so forth. In the part dealing with shotguns he takes up the question of ...

So that to avoid combing his baldish pate with your fork you must pass the items of your meal in quite a sideways trajectory.

... vicinity of the target is reached and he prepares to drop his bombs, usually eight in number. A little before he is over the spot the first bombs will be released, for the trajectory of the bomb follows the course of the machine if the latter keeps on a straight course and when it explodes the airplane is still overhead. Down far below will be seen a tiny burst of flame; possibly a large fire blazes up and the pilot knows that his work is good. He then turns ...
