There are quite a few in that list which are false, including the one about a duck's quack.

The ducks quack thing isn't true. And the paper thing needs to be clarified, as you can fold a piece of tissue paper the size of new hampshire alot more times than a sheet of printer paper. And I seem to remember that two planets rotate in the opposite direction of ours.

...and Edison invented the electric chair. He called it The Westinghouse because it used AC, he was a firm advocate of using DC for transmission lines.

True that.

I posted this same list once and it was cut to pieces!! ;)

The size of the paper is irrelevant, it's the thickness that matters.

But the size is relevant, as you fold something in half, the size halves and the thickness doubles. If you have a larger piece of paper, then you have more room to fold. CREASING might not be possible, but folding still is. Can you fold something that is 1' thick but 100' long? I'm sure you can.

I'm sorry to say that it's not true about the quack of a duck. Quacks echo as much as any other sound in nature. However, there is a way to avoid an echo, the problem is that it depends on your distance from the object reflecting the sound, and not the type of sound itself.

Sound travels in waves, and all of these waves have a specific wavelength (the distance from point on a wave to the exact point on the next). If by chance, the distance between the emitter of the wave and the reflector is exactly on one of the nodes of the wave... the sound will not reflect back at all. There will just be a standing wave created between one place and another, as all points on the wave would have zero net displacement. You can try this in the lab with a strobe light and a string oscillator. Also, if you have done the experiment with the column of water and the tuning fork, you will notice dead spots. These are distances where no matter what you do with the tuning fork, you won't hear anything coming from the tube.

The second way to avoid an echo, is to use a partially reflective material. This method is one of many that helps to hide aircraft from radar. If you position a half-reflective layer exactly one-quarter wavelength in front of a fully reflective layer, the wave will cancel itself out. By separating the layers by 1/4 wavelength, half the wave bounces off the first, and the other half of the wave bounces of the second. The travel time from the first layer to the second and back again, is exactly 1/2 wavelength, which means that the positive peak displacement is balanced exactly by the negative peak displacement. Again, no net displacement = no discernable wave return.

wright brothers flight: 120 feet
current 747 wingspan: 211feet 5inches (747-400)


that one is at least correct.
