Yeah, well, Edison is vastly overrated anyway. He had a good PR department. I'll give him that. Nikola Tesla. Now that's a guy that rocked. Our entire system of electricity is based on that guy's work.

I agree.

That's shocking. :speechls:

Tesla, or the agreement?

The Washington Monument had already had a monument condom. OK, really it was a scaffolding during renovation, but it pretty much resembled a monument condom

I can't seem to think of anything except for a visual of a monumental amount of spooge that is going to take quite some time to dry up before disposal.

Electricity. :lol:

I don't think this one is "ribbed for her pleasure".

Hello, Cellar!
 

I probably could pick a better way to introduce m'self, but this is a topic I got mildly interested in one day during an aircraft systems.
the speed of sound does not depend on density or temperature, except as how these things affect the stiffness of the medium. So warm rubber( quite dense) transmits sound slower that glass (less dense). Stiffness determines the speed of sound in any medium.

welcome to the Cellar, hideouse.
Nice piece of info there.

So the humming will transmit faster if it's harder...hmmm....
Uh....thanks hideouse.....that calls for some experimenting.
Oh, and I second the welcome. :)

I guess since you've shown me yours I'll show you mine... :)

I was a sonar technician on the USS City of Corpus Cristi for two years, so my study of acoustics is a bit more thorough.

If what you say is true, why is the speed of sound in water five times that of the speed of sound in air? Neither are very stiff. What you say is true on the surface, but when you dive a bit deeper it becomes more clear.

Check out this page here for information.

Jump out of an airplane over the water and you'll see the difference in stiffness. :lol:

I thought the key word here was density. Surely water is more dense than air. But whadda I know. I'm just an old Marine.
