this is so sad

Strictly speaking, that's not exactly the case, but close enough for jazz. Frequency is a measurable faculty of the physical world: literally how many times a wave completes a cycle in a second.

Pitch is a perceptual phenomenon that lives solely in the domain of cognition. There is a VERY close relationship between frequency and pitch--waves of different frequencies trigger nerve firings associated with different pitches, and those pitches relate to each other in a manner similar to the frequencies--but they're not truly the same thing.

So kind of like electromagetic wavelength vs color?

No...like electromagnetic frequency vs color.

Wavelength isn't the same as frequency.

WL = distance from one peak to the next.

Frequency = time...how many peaks in a given amount of time.

Color = the human perception of a given EM wavelength.

Well, since the speed of the wave is constant in a given media, potato potahto.

But are you actually saying that the cone opsins react to different frequency of peaks? For that to happen they'd need corresponding osscilators, no? Sounds more likely that the physical property of the proteins in the cells correspond to the physical property of the wave.

But what do I know. I slept through biology.

No...they are measurements two distinctly different things. Distance (WL) and how many over time 1/T (frequency).

Related? Fo sho...but not the same.

No....the frequencies of light are well beyond human perception and rather un important to our perception of visible EM wavelengths...way way way way too fast. If we could perceive the actual wave lengths life would look like a TV being recorded on film...with visible shifts across our vision.

Sounds more likely that the physical property of the proteins in the cells correspond to the physical property of the wave.

They do....but the freq is too high to register as anything but an unwavering source/reflection of light...unless there is a Doppler shift, or some outside force fucking with it.

But what do I know. I slept through biology.

And physics too...;)

Yes I know.

No...not at all.
*glances up* Ah, I see I didn't catch your last edit. Wavelengths it is then. My initial analogy was in fact correct. The physical properties our sensory organs react to, vs the way our brains inteprets them. Ears react to the frequency of pressure variations, not to the lenth of the soundwave, which most of the times is longer than your head is wide. Eyes react to the wavelength.

And physics too...;)
If it makes you feel smart, you can have that one.

I guess since they are so intertwined and the constant speed of light, for all intents and purposes you're right...potato potahto.

There isn't enough happy pills on earth to make me think for one second I'm anything but an insignificant moron....keep it, I don't need it.

Is there enough good weed? I once read someone had put "all intensive purposes". Cracked me the hell up!

Not quite true either. We use inter-aural phase differential (and time-differential) to locate the origin of sounds--that is, we take into account the length and height of the wave relative to our head and other objects, including the time it takes for the remainder of a wave to travel around our head to the other ear. (We also use the way the physiology of our outer ear--the pinna--reflects sound to determine up from down.)

For waves smaller than the average head, phase differential becomes almost impossible to determine, and we have great difficulty locating the origin of the sound without a stop and start. Think of mosquitos, cell phones, and of course pure sine tones. Without a time-differential clue--a marked start after a marked stop--we have no good locational information.

OK I admit I don't know the size of this whale but Seaworld moves adult whales all the time.

They move orcas. I doubt they've ever moved an adult humpback, which is the species in the photo.

(Hint: humpbacks are much, much bigger and heavier than orcas)


i read this thread and i see... pocket protectors?!

Racist.
 
I asked one of my friends to explain pitch. He grabbed an empty beer bottle and blew into it. He grabbed a bottle that was half full and blew into it.

I have the best mates.

Frequency defines pitch. Whether it be high or low. :)
 
I'm not clicking that shit. I've tried listening to the music you listen to, mate.

It's worse than listening to pigs squealing to death.

a life without connection...

I often feel like that. Like I am not on the same wavelength as everyone else or communicating at the same level.
 
Aah, I've read this before and it is sad.

Dolf, your fucking AV makes me want to kill myself. Jesus.
