“Sounds” of individual molecules captured

[cosmictraveler]

Phys­i­cists say they’ve rec­orded ti­ny vibra­t­ions of in­di­vid­ual mol­e­cules, that could be called sounds—de­pend­ing on how you de­fine sound—and put them in au­di­ble form.

The re­sulting bell-like tones can be heard here..http://www.mpg.de/video/FilmundAudio-KdM.wmv. But the study went much fur­ther.

The vibra­t­ions in their orig­i­nal form, sci­en­tists said, are too fast and small to hear, but oth­er­wise fit the phys­i­cal de­scrip­tion of what makes a sound: they can pro­duce si­m­i­lar vibra­t­ions in neigh­bor­ing mol­e­cules, which do the same to their neigh­bors, and so forth, spread­ing the os­cilla­t­ions out­ward.

I would guess you viewed his post initially after he'd "Cut/Pasted". It's possible that the Asterixes are a way to try and thwort articles being 'Stolen' through Cut/Paste. however as long as the article isn't reproduced in it's entirety and linked to it's root source for the most part we don't hear complaints.

thanks stryder!

oooo, so they don't make a squishy sound. More of a ringing. that's odd.

That's interesting. Many people who practice deep meditation have had dreams/visions of the unverse before creation, where they describe what they believe is energy all around them making a humming sound. A simiilar sound religious people use when praying in many cultures. Amen is thought to come from this sound too, or should I say aaaaaaaaaaaaaaaahhhhhmeeeeeeeeeeeeeeeeeeeeeeen?

"Tiny vibrations of molecules" are phonons. They're otherwise called "allowed states" (modes) of vibration.
Someone managed to store a bit of light from a laser as a phonon, and read it back.

P.S. I remember someone has recorded the sound the Sun makes, or they've made the sound (energy) audible. It rings like a bell, too.

I've had a ringing in my head for many years now, mostly after I drink to much!

are you sure its not that one tiny molecule inside your skull screaming out of boredom?

Could very well be but I'm not certain there's only one.

I've noticed transient "ringing" type noises for as long as I can remember. Sometimes it doesn't happen for ages, then I get a rash of "pings" or "gong" type sounds. It's like hearing a sudden ringing or singing sound inside my ears.
When I learned about the structure of the inner ear and the Eustachian and tear ducts, I thought that it was because of sudden pressure changes, or something.

It's like a sudden "on" signal, that dies away slowly, but quite loud at first. Sometimes this happens several times a day or even in an hour. Always had it, noises in my head.

P.S. It's never a rising or falling tone -the pitch doesn't change, only the amplitude and only a single "note". But it's all over the spectrum -sometimes near middle C maybe, sometimes quite high and every note in between, but it's not tuned to A=440Hz like a piano, or anything.

P.P.S. Maybe I should go ask for a tune-up? "They" might get a little more interested than I'd prefer though.
