Light Gas Gun
The light-gas gun is an apparatus for physics experiments, a highly specialized gun designed to generate very high velocities. It is usually used to study high speed impact phenomena (hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids. Some basic materials research relies on projectile impact to create high pressure: such systems are capable of forcing liquid hydrogen into a metallic state.

Famous quotes containing the words light, gas and/or gun:
“The light struggled in through windows of oiled paper, but they read the word of God by it.”
—Ralph Waldo Emerson (1803–1882)
“... when I awake in the middle of the night, since I knew not where I was, I did not even know at first who I was; I only had in the first simplicity the feeling of existing as it must quiver in an animal.... I spent one second above the centuries of civilization, and the confused glimpse of the gas lamps, then of the shirts with turned-down collars, recomposed, little by little, the original lines of my self.”
—Marcel Proust (1871–1922)
“What cannot stand must fall; and the measure of our sincerity and therefore of the respect of men, is the amount of health and wealth we will hazard in the defence of our right. An old farmer, my neighbor across the fence, when I ask him if he is not going to town-meeting, says: “No, ‘t is no use balloting, for it will not stay; but what you do with the gun will stay so.””
—Ralph Waldo Emerson (1803–1882)
