These men have not an atom of common sense. It is singular to see a man like Guibert, with practical ideas on most things, give a long dissertation to demonstrate that the officers of his time were wrong in aiming at the middle of the body, that is, in firing low. He claims this is ridiculous to one who understands the trajectory of the rifle. These officers were right.
For Fabre was born a poet, and mathematics borders upon poetry; he saw in algebra "the most magnificent flights," and the figures of analytical geometry unrolled themselves in his imagination "in superb strophes"; the Ellipse, "the trajectory of the planets, with its two related foci, sending from one to the other a constant sum of vector radii"; the Hyperbole, "with repulsive foci, the desperate curve which plunges into space in infinite tentacles, approaching closer and closer to a straight line, the asymptote, without ever finally attaining it"; the Parabola, "which seeks fruitlessly in the infinite for its second, lost centre: it is the trajectory of the bomb: it is the path of certain comets which come one day to visit our sun, then flee into the depths whence they never return."
It was like an inflated balloon, turned loose to fly around a room. Air jetted from it with terrific velocity, so that the tank was, for the period while its air lasted, a true rocket. It struck 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.
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.
Our father sat in front with the reins in his hands and his feet thrust out to steer, and away we went clinging fast behind him. Sometimes we swept triumphantly to the bottom; at other times we would collide with some hidden obstacle, and describe each a separate trajectory into the snow-banks.
He was falling, around the Earth, his forward motion exactly balancing his downward motion, in a locked ellipse, a closed trajectory. His mind cleared very fast that must have been another phase of the devil-killer shot coming into action.
"It's a shocking bad light for judging distance," said he. "This is where the low point-blank trajectory of the Lee-Metford comes in useful. Well, we'll try him at five hundred." He fired, but there was no change in the white camel or the peering rider. "Did you see any sand fly?" "No, I saw nothing." "I fancy I took my sight a trifle too full." "Try him again."
The advantage of using these instruments when you are besieging permanent works is that you can hide them behind an obstacle, such as a hill, and that the heavy gun in the fortress cannot get its shell on to them because that shell has a flatter trajectory. The disadvantage is that the howitzer has a very much shorter range than the gun size for size.
The thunder of his engines drowned all sound so he could not hear the never-ceasing booming of the guns, the never-ending crash of exploding shell. Once he saw a heavy German shell in the air he glimpsed it at that culminating point of its trajectory where the shell begins to lose its initial velocity and turns earthward again.
Then he proceeded with great deliberation to interpret his oracular utterance; but first, with a powerful facial exertion, he wrenched his mouth and nose to one side, inhaling vigorously through the lee nostril, then cleared his throat with the sound of a strongly-driven wood-rasp catching on an old nail, and sent the result whirling from his mouth at a butterfly on a stem of lignum sent it with such accurate calculation of the distance of his object, the trajectory of his missile, and the pace of his horse, that the mucous disc smote the ornamental insect fair on the back, laying it out, never to rise again.
