The vertical error, however, depends more on the weight of the arrow, on the feathering, the holding time, the maintainance of tension, and on the release of the bowstring. There are many problems in the ballistics of archery that are unsolved, waiting the experiments of modern science. Empirical methods have dictated the art so far.
The assembly felt that its president was coming to the delicate point; it redoubled its attention. "A few months ago, my brave colleagues," continued Barbicane, "I asked myself if, whilst still remaining in our speciality, we could not undertake some grand experiment worthy of the nineteenth century, and if the progress of ballistics would not allow us to execute it with success.
But science, in particular, represented the major investment of this library: books on mechanics, ballistics, hydrography, meteorology, geography, geology, etc., held a place there no less important than works on natural history, and I realized that they made up the captain's chief reading.
This would be a dangerous pressure in an old-fashioned shoulder arm; while a bullet made only of lead would strip on striking the rifling and pass right through the barrel of the gun without taking any rotary motion whatever. It might at first seem that the powder is the only thing to be considered; but high ballistics can only be obtained when everything else is adapted to its use.
If, indeed, it be a matter of little importance to statistics, mechanics, hydrodynamics, and ballistics, that the true cause of the fall of bodies should be known, and that our ideas of the general movements in space should be exact, it is quite otherwise when we undertake to explain the system of the universe, the cause of tides, the shape of the earth, and its position in the heavens: to understand these things we must leave the circle of appearances.
Now and then he would creep from the shyness which enveloped the inventive side of his nature, and would talk with her with unintelligible earnestness of these dreadful engines; of radial and initial hoop pressures, of drift angles, of ballistics, of longitudinal tensions, and would jot down trigonometrical formulae illustrated by diagrams until her brain reeled; or of his treatise on guns of large caliber just written and now in the printers' hands, and of the revolution in warfare these astounding machines would effect.
This does not mean that intimate knowledge of the details of construction of a machine is necessary in order to operate it; it does not mean, for instance, that a sharp-shooter must have a profound knowledge of the metallurgy of the metal of which his gun is mainly made, or of the laws of chemistry and physics that apply to powder, or of the laws of ballistics that govern the flight of the bullet to its target.
It was a solid round-shot, evidently cast in some private foundry, whose proprietor, setting the laws of thrift above those of ballistics, had put his "imprint" upon it: it bore, in slightly sunken letters, the name "Abbott." That is what I was told I was not present.
"And Captain Strawn received a wire from a ballistics expert in Chicago this morning, confirming our conviction that the same gun which fired the bullets against Judge Marshall's target fired the bullet which killed Nita Selim.... You've washed that plate long enough. Let me dry it now.... And there are other things, Penny " "Such as " she challenged in her angry, husky contralto.
Silence!" was heard on all sides. When the agitation was calmed down Barbicane resumed, in a graver tone, his interrupted speech. "You know," said he, "what progress the science of ballistics has made during the last few years, and to what degree of perfection firearms would have been brought if the war had gone on.
