"Yes, Nicholl, but slight as it was," answered Barbicane, "upon a distance of 84,000 leagues it was enough to make us miss the moon!" Barbicane had evidently found the only plausible reason for the deviation. However slight it had been, it had been sufficient to modify the trajectory of the projectile. It was a fatality.
He had recently heard a good deal about the Prussian new model for field artillery, and he had read, in the French journals, reports of their wonderful range and flat trajectory.
The problem of the Sirex is now solved. The trajectory is composed of equal elements, with an invariable angle between them; it is the curve whose tangents, divided by infinitely small distances, retain the same inclination between each one and the next; the curve, in a word, with a constant angle of contingence. This characteristic betrays the circumference of the circle.
He heard low voices in the next room, but he could only catch a few phrases. An unknown voice was congratulating himself that the ball had not remained in the body; undoubtedly in its trajectory it had passed through the lung. Here arose a chorus of exclamations of astonishment, of repressed sighs, and then of protest from the unfamiliar voice. Yes, the lung; but there was no cause for alarm.
In firing at short range, the trajectory is not as rigid as could be desired, the parabola is exaggerated, the line of the projectile is no longer sufficiently rectilinear to allow of its striking intervening objects, which is, nevertheless, a necessity of battle, the importance of which increases with the proximity of the enemy and the precipitation of the discharge.
This is what is known as throwing "with a high trajectory," and it is received with great applause. The trajectory turns out to be too high, and all his darts land in the wall above the door. Hassel throws with "calculation." What he calculates it is not easy to understand.
Trajectory and force would depend upon velocity; the latter must depend upon the volume of gas generated by explosion. The rifle was made by Gibbs of Bristol. The weight was 21 lbs., length of barrel 36 inches, weight of spherical belted bullet 3 ounces, of conical bullet 4 ounces, charge of powder 16 drams. The twist was one full turn in the length of barrel.
The base of the bullet had a tendency to turn towards the moon under the influence of the centripetal force; but the centrifugal force still predominated, and it became probable that the rectilinear trajectory would change to some curve the nature of which could not be determined. Barbicane still sought the solution of his insoluble problem. The hours went by without result.
Time is invention or it is nothing at all. But of time-invention physics can take no account, restricted as it is to the cinematographical method. It is limited to counting simultaneities between the events that make up this time and the positions of the mobile T on its trajectory.
He watched bleakly as the Horus's missile arched in its impossible trajectory, as the light cruiser flung everything that could be gotten out to try to stop it, while its transmitter shrieked gibberish to the stars. There was a blinding flash of light. Then nothing.
