"Jules Verne's "From the Earth to the Moon" and "A Trip Around It"" - читать интересную книгу автораconsider it from a moral point of view. The cannon-ball,
gentlemen, to my mind, is the most magnificent manifestation of human power. If Providence has created the stars and the planets, man has called the cannon-ball into existence. Let Providence claim the swiftness of electricity and of light, of the stars, the comets, and the planets, of wind and sound-- we claim to have invented the swiftness of the cannon-ball, a hundred times superior to that of the swiftest horses or railway train. How glorious will be the moment when, infinitely exceeding all hitherto attained velocities, we shall launch our new projectile with the rapidity of seven miles a second! Shall it not, gentlemen-- shall it not be received up there with the honors due to a terrestrial ambassador?" Overcome with emotion the orator sat down and applied himself to a huge plate of sandwiches before him. "And now," said Barbicane, "let us quit the domain of poetry and come direct to the question." "By all means," replied the members, each with his mouth full of sandwich. "The problem before us," continued the president, "is how to communicate to a projectile a velocity of 12,000 yards per second. General Morgan will be able to enlighten us on this point." "And the more easily," replied the general, "that during the war I was a member of the committee of experiments. I may say, then, that the 100-pounder Dahlgrens, which carried a distance of 5,000 yards, impressed upon their projectile an initial velocity of 500 yards a second. The Rodman Columbiad threw a shot weighing half a ton a distance of six miles, with a velocity of 800 yards per second-- a result which Armstrong and Palisser have never obtained in England." "This," replied Barbicane, "is, I believe, the maximum velocity ever attained?" "It is so," replied the general. "Ah!" groaned J. T. Maston, "if my mortar had not burst----" "Yes," quietly replied Barbicane, "but it did burst. We must take, then, for our starting point, this velocity of 800 yards. We must increase it twenty-fold. Now, reserving for another discussion the means of producing this velocity, I will call your attention to the dimensions which it will be proper to assign to the shot. You understand that we have nothing to do |
