You're claiming this with which evidence? I know our brains make up things if we don't know what they are, but if I'm understanding you correctly you're talking about forming an entire object from imagination and placing it in our vision...Moriarty said:
You need both and good sense to tell when one of them, if not both, is leading you astray. Also I thought Indigo was the one the invented. Also just for science based history look up Phlogiston, it is a very important lesson about how you can have all the facts and still have the wrong answer.
A star is made up of many elements that fuse together to create energy. The energy causes the elements to reach an "excited state [http://en.wikipedia.org/wiki/Excited_state]". When returning to the "ground state", a photon is emitted. Different elements produce different colours due to then possessing different energy levels. Stars tend to have a wide variety of elements so produce a full spectrum of colours. Some stars, however, possess more of a single element than other stars, so produce more colour in one part of the spectrum. This allows many different coloured stars to exist such as green, orange, blue and, in the case of our sun, yellow. These stars still produce a full spectrum, but are noticeably more abundant in a particular hue of light.interspark said:
Red giants on the other hand are made up predominantly of the element iron, so produces little but the red part of the spectrum.
I hope you understand this. Trying to recall my school lessons is hard when very tired. Anything you don't understand, just google it.
Yes, an octave has 8 notes, but a scale has only 7 notes (only exceptions being pentatonic and chromatic scales). As an example, C Major has the notes C, D, E, F, G, A, B and then you have gotten back to the starting note of C, so there's only 7 different notes in the scale. Newton was supposedly applying the same principle to the colour circle:spartan231490 said:
...with it going from primary colours of Red to Green to Blue (with all the colours in between: yellow, violet etc.) and then going back to red again. 7 colours before going back to the 8[sup]th[/sup] colour or the original colour, like a musical scale. This is the design that the colour wheel [http://wiki.blender.org/uploads/9/94/BSoD-ItL-colour-wheel.png] was based upon.
Of course, whilst the colour-wheel design is useful in Art, it provides little use in Physics, where we know that the electromagnetic spectrum is a linear scale with areas of it non-visible by humans at both extremes and visible light making up a section in between.
Empiricism vs Rationalism, eh?
I tend to like to think of myself as a rational and logical person, so I would tend to go with the facts. But the senses (in this case, sight) should not be discounted, as even though they are not insusceptible to doubt they still provide valuable information, and really without the senses it would be very difficult to find any facts. So I'd have to say that both are important.

People cannot act except based on their own perception. One of the factors that separates the intelligent creatures from the not so intelligent ones is the ability to purposely misrepresent reality to alter the perception of another in one's favor. Lying and trickery is integral to the league of intellect we're in, and as such when confronted with verifiable facts that conflict with things I have observed, I will often attempt to find the misrepresentation I have been fed.

Not sure if I've already been ninja'd on this but as the great Obi-Wan Kenobi once said "Your eye's can deceive you don't trust them".
Okay what I mean by using that quote is that... our eye's and mind can play tricks on us, solid facts are more reliable in some cases.

I'd like to be able to say the facts, but I'd be lying.
Eyes may be subjective, but it's also instinctual to believe what you see.

Typically my eyes. I don't like relying on my eyes but I like relying on facts even less. As far as I'm concerned there are no 'facts' as we define them (a philosophical viewpoint I really don't want to argue about right now, so please no quoting to tell me how wrong I am), so that leaves me with the evidence of my eyes, which I know full well can be deceived and are capable of flaws.
Also OP: Hung is the past participle of anything which was in the past suspended. Hanged refers specifically to a human being who was in the past suspended by the neck. One theory holds that it was a legal term, derived to only have that meaning, but of course the origin of the word has been lost long ago.

I didn't exactly say that, the brain just doesn't grab a random object and places it in our field of view, we would notice the error (sometimes it happens tho, and we DO notice) but it fills many gaps in our vision.Abengoshis said:
Only a VERY small area in the center of your field of view is exactly as sharp as you perceive your entire field of view to be, it's the brain that gives you the illusion of having this huge field of view.
Also, the part of your field of view closest to the edge isn't in colour, you just don't notice.
Your eyes even have a blind spot, which the brain fills completely without you noticing, there is a trick which shows you this.. something about a black point on a paper disappearing if you look at the right angle.
Ahh, but one must remember! White is not the absense of colour, but the presense of all colours. So the sun is indeed yellow, just it is also the other colours of the spectrum as well.interspark said:
While I'm also busy nitpicking at things, you should also note that violet is the spectral colour, while purple is considered to be a non-spectral colour, as purple is obtained by mixing red and blue light, while violet occurs naturally in the spectrum.
As far as the poll goes, I'll believe half of what I see, and none of what I hear.
