37 freakin' vibrations.

Play with waves and vibrations

OK, great, we smell vibrations. How? All right?

And the other theory is that we smell molecular vibrations.

And the pitches, the notes, as you know, are just vibrations.

Cities should be full of vibrations, full of sound, full of music.

It's actually emitting ultrasound low level ultrasound that's about 100,000 vibrations per second.

It's either E natural, and 659 vibrations per second, or E flat, at 622.

So no one actually needs to muck up the production of sound with wire vibrations.

Instead, they detect sounds through their tongues and feel vibrations through sense organs in the skull.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

Calculate the vibrations, the purple spectrum is that new fellow, the white one is the old one.

And then you start cranking the computer to find other molecules, related or unrelated, that have the same vibrations.

Now, the slight fly in the ointment is this that if we smell molecular vibrations, we must have a spectroscope in our nose.

Consider this. If you look at the instrument, a French horn, notice that the vibrations of the airstreams are affected by the shape of the instrument.

Still, we brazenly drop this enigma into the first days of a first year course without batting an eye. We write down equations that show how friction slows the motion of sliding objects or dampens the vibrations in springs, but, ultimately, the math merely reproduces our observations while disguising our ignorance of what underlies them.
