When Noise Breaks a Window.
Noise is an irregular wave in the air—which is a real thing, and has weight and power, remember. A wave of air may break a window exactly as the wave in the sea will break a breakwater, though, as the name tells us, the breakwater will break the wave, as long as that wave is not too strong.
If you will think a minute you will see that every time a noise gets through a shut window it shakes the window. If the noise is coming in from the street, the air outside is thrown into waves which pass through it until they strike the window, and shake it; then the window shakes the air inside the room in exactly the same way as the air outside shook it, only perhaps not quite so strongly. And so the noise reaches you, just as if you had heard it outside, only not quite so loud. Well, plainly, the noise has only to be loud enough—that is to say, the waves in the air have only to be big enough—to shake the window more than it can stand, and then it breaks.
Odd Real-estate Discovery.
For over thirty years four well-known families of Appleton, Wis., have been living in homes they supposed they owned, but did not. They bought on pocket-map description instead of official map. John Freude owns the home of William Moyle, across the street from him, and Moyle owns Freude’s supposed home. The same situation is found in the cases of Peter Zonne and Edward Jennerjahn.
How Much Does Snow Weigh?
Handbooks of useful information, as they are called, do not give the weight of a cubic foot of snow, so Charles S. Evans and Leonard S. Jones, lawyers, of Edenburg, Pa., carefully measured a cubic foot of the wet snow which fell on Tuesday and found it weighed 14.58 pounds.
Wednesday and Thursday were very cold, and much of the dampness in the snow evaporated. Evans and Jones overlooked this fact when they wagered Elmer Davis and Edward O. Jones that snow weighs 14.58 pounds to the cubic foot.
When the quartet weighed a second foot of snow it was found to weigh 11.97 pounds. Then Evans and Jones entertained at dinner.
