I saw a blue orange once. But I was tripping....
okay mssorter... find a red object (to you) get a frend (or omega) and ask them if it is red to them... if they say yes... then wala, you were absolutly wrong! omega's rite u have absolutly no proof... hmmm, lets see, mcmike avator, above where it says Pizza Hut, is red, im sure everybody else will say the same?
actually i go to a private school in moscow. it is american , not russian. in costs $32,500 a year. i just recently recieved a 1550 on my SAT exam and i have already been accepted to the Yale biomedical engineering department.
no, i did not fail my TOK classes, i recieved an A+ on my report on perception.
you guys are funny. it is your lack of abstract thinking that slows down this world.
BTW- the kinda proved my theory. if you were reading they talked about a chemical in our bodies that senses the color spectrum. we all have the same chamical but it could vary a miniscule amount from one person to the next. my red could not necessarily be your blue. but my sky blue could be your light blue.
what have you got to show for yourself
BioLogos> Before confusion sets in. A difference in perception as you described (the one sees yellow – the others see green), is still a FAR step from the original posters claim of the TRUTH of the world being, that it is in yellow/gold.
You see, that ONE person says “that colour is yellow” while everyone else says “no it’s green” is different from EVEVERYONE seeing different colours, and ALL calling it GREEN. The one person sees yellow and CALLS it yellow. He/she doesn’t SEE yellow and call it green,
The point is: We seem to be aware of what YELLOW and GREEN respectively are supposed to LOOK like, so even if a minute difference in our receptors make me tend a little to either side of the colour in question, this does NOT – in any way – mean I do not see blue where you see red. Or a circle where you see a square.
The strange optical illusions you mention messes up everyone. If it doesn’t work, we can DESCRIBE and see it physiologically: Here is a receptor that’s a little heavy on the yellow, here’s someone who’s colour blind. It’s not so, that two completely healthy, and (barring the usual differences between humans in height, weight etc) have normal functioning eyes, do not SEE yellow as yellow.
And the possibility to ALTER our genes, to CREATE someone who can then SEE UV-light, is again not the point of this topic. Again there would be an actual biological alteration that would ACCOUNT for this new sight.
And that one person looks at the sky and says “hey, it’s blue” while the girl next to him says, “nope, it’s light-blue” doesn’t show that we PERCEIVE a colour as, say, light-blue and CALL it blue.
Lag> Explain string-theory to you in this forum??? (Coughs) How far are you in your physics education? 😄 I doubt I’ll be able to teach you string-theory, which takes up at LEAST a few chapters in a graduate book here – not to mention how awfully off-topic it is. If your down with path-integrals, BST, loops, and stuff like that, as well as quantum field theory we might be getting somewhere 😉
DarkCore> You listing where you supposedly go to school does NOT prove your hypothesis. Carl Sagan once said: “Extraordinary claims require extraordinary proof.” Where IS your proof?
Prove that colours do not exist.
Prove that sound is a wavelength of the electromagnetic spectrum and that it does not exist.
Prove that one person’s red is another persons blue.
Prove, that touch does not exist, because if it did my fingers would MELD with the stuff i touched.
(See, I don’t believe you, and I AM a scientist).
*shrugs*
Sorry bout that i was just being smart, your sitting there asking for all this proof and then just claim you're a scientist and expect everyone to believe you.
I guess it can't be prooved, at least i can't think of any ways that it can, i was hoping you could.
Sorry to have wasted your time, anyway you think you could proove it would be great. 😄
Mordecai> I was referring to DarkCore's original post, where he made a lot of claims, didn't prove anything, but just said, that if we didn't believe him, we should ask our science teachers.
Since I am a scientist (M.Sc. in physics) I don't NEED to ask my teacher 😄
DarkCore´s the one making a claim, hence the burden of proof rests on him.
Hmmm. Well, you can ask, say, JediHDM, or SimplePriest, JKozzy or Burlyman if the name of the author of "A charged scalar-field in a time-machine wormhole background" matches with the name given on the e-mails I send them.
Search for "A charged scalar-field in a time-machine wormhole background" on, say, google.
Mark the name, send a PM to either of those gentlemen and ask if that is my name.
And then - finally - ask yourself if that doesn't sound like a physics thesis 😄
If that doesn't work, I'll figure out something else. ✅
From Omega: "The point is: We seem to be aware of what YELLOW and GREEN respectively are supposed to LOOK like, so even if a minute difference in our receptors make me tend a little to either side of the colour in question, this does NOT – in any way – mean I do not see blue where you see red."
Yes, you are correct – people do generally agree that one wavelength is the color “red” and another is “blue”, and given the way the machinery in your eyes works, I don’t see how a mutation in the receptor proteins could cause someone to confuse red and blue(unless they lacked the color receptors completely and perceived the world as shades of grey) because these colors are so far apart in the spectrum.
However, it is important to realize that we agree to call light of a particular wavelength “red” because our parents teach us that something that looks “like this” is called red. No one knows exactly how a separate person EXPERIENCES the perception of this wavelength called “red”. The experience “red” is created by our brain interpreting the ratio of signals from the red, green, and blue photoreceptor cells in your eyes. Does my brain create the same experience as yours? Probably, but how can we know? Someday, when neurobiologists understand how the brain works, we will probably be able to answer this question, but until then….
The fact that the brain takes the reception of a given wavelength (which is unquestionably real) and then creates the experience “red” from this is perhaps the basis for the DarkCore’s statement that “colors do not exist”. Of course, the different wavelengths exist, but the experience “red” is a creation of our brains.
To put this in some perspective -- have you ever pressed on your eyeballs in the dark? You will most likely "see" colors. In this case, you are experiencing the perception of pressure as a color! I'm wondering whether something vaguley analogous to this perception of "pressure" as color could be mechanism for Neo's ability to see the machines after he is injured...
