Projectile Quotes (3 quotes)

Aluminum is at once as white as silver, as incorrodible as gold, as tenacious as iron, as fusible as copper, and as light as glass. It is easily worked; it is widely spread in nature, alumina forming the bases of most rocks; it is three times lighter than iron; in short, it seems to have been created expressly to furnish material for our projectile!
Planning a spacecraft to be fired from a cannon to the moon. In From the Earth to the Moon (1865, 1890), 38.

PROJECTILE, n. The final arbiter in international disputes. Formerly these disputes were settled by physical contact of the disputants, with such simple arguments as the rudimentary logic of the times could supply —the sword, the spear, and so forth. With the growth of prudence in military affairs the projectile came more and more into favor, and is now held in high esteem by the most courageous. Its capital defect is that it requires personal attendance at the point of propulsion.
The Collected Works of Ambrose Bierce (1911), Vol. 7, The Devil's Dictionary,  268.

The discovery of the conic sections, attributed to Plato, first threw open the higher species of form to the contemplation of geometers. But for this discovery, which was probably regarded in Plato’s tune and long after him, as the unprofitable amusement of a speculative brain, the whole course of practical philosophy of the present day, of the science of astronomy, of the theory of projectiles, of the art of navigation, might have run in a different channel; and the greatest discovery that has ever been made in the history of the world, the law of universal gravitation, with its innumerable direct and indirect consequences and applications to every department of human research and industry, might never to this hour have been elicited.
In 'A Probationary Lecture on Geometry, Collected Mathematical Papers, Vol. 2 (1908), 7.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
