Sergio finally realizes

Am I the only one who paid attention in class?

The sky appears blue to us on a clear day, because the atoms of nitrogen and oxygen in the atmosphere separate the suns white light into its many colors, and scatter them throughout the atmosphere.

The wavelength of the blue light scatters better than the rest, predominates over the other colors in the light spectrum, and makes the sky appear blue to us.

The scientific name for this phenomenon is the Tyndall effect, more commonly known as Rayleigh scattering.

This phenomenon describes the way in which light physically scatters when it passes through particles in the earths atmosphere that are 1/10th in diameter of the color of the light. The light spectrum ranges in wavelength from red to violet, and, since the wavelength of the blue light passes through the particles with greater ease than the wavelengths of the other colors of light, the sky appear blue to the naked eye.

The human eye has three types of light receptors, known as cones, located in the retina. The cones are either considered to be red, or blue, or green, based upon their strong response to light at these wavelengths. As light stimulates these receptors, our vision translates the signals into the colors we see.

When gazing at the sky, the red cones respond to the small amounts of red light scattered, and even less strongly to the orange and yellow wavelengths. Although green cones respond to yellow, their response to scattered green and green-blue wavelengths is stronger. Finally, colors near the strongly scattered blue wavelengths stimulate the blue receptors.

In short, the skylight stimulates the red and green cones almost equally, while stimulating the blue cones more strongly. For these reasons, our vision naturally adjusts as clearly as possible to separate colors.

That's simply the explanation for why the sky is blue. The "sky is blue" is a descriptive term, and an accurate description of something perceptual like the colour blue. The sky itself being nothing more than a construct of the human mind--there's no such entity as "the sky"...it's simply what humans call the experience of looking up at the atmosphere. That construct of the human mind IS blue, because that is the colour that it appears. Space is not blue.

If true, I expect Real Madrid is counting on getting Rudy also. I smell another 6-year rebuild for the Blazers in the works.

Because Rudy might leave?

he's THAT important to the future of this franchise??

 

[julius]

Depends on your perspective. As compared to, say, Tony Parker, no, he didn't cut it at the NBA level. But as compared to 99.9999% of the people on earth...
He made it to the NBA and played a few years. That's not a shabby achievement. I'd take his basketball career over mine.

barfo

I didn't know you had a basketball career. What team did you play for?

 

[MARIS61]

Yeah, yeah. But you didn't answer the questions. Supposing your car is blue, why is it blue?

barfo

Because that's the color it was painted.

This must be longhand for, " ... and Sergio still sucks and couldn't cut it in the NBA."

 

[barfo]

I didn't know you had a basketball career. What team did you play for?

The Virginia Squires, high school PE league. My earnings were somewhat less than Sergio's. But of course, salaries were lower then, especially in PE class.

[barfo]

Because that's the color it was painted.

And what would your 7th grade science teacher say about that answer?

barfo

 

[BBert]

You'd have a point if he played for free. He made $4.7 million playing a game he just isn't good at.

$4.7 MILLION for Sergio Rod-freaking-riguez.

Does anyone remember how much Raef-Freaking-LaFrenz got paid for not even stepping on the freaking court? Or how much the Blazers paid Stevie-Freaking-Francis to NOT even suit up for the Blazers?

Sergio Rodriguez was certainly not overpaid by NBA standards. IMO Sergio could continue his career as a career backup in the NBA, or he could go back to Spain for more money, more glory, more playing time, and more fun. He made the right choice.

 

[MARIS61]

But, then, what is the definition of "blue"? If the sky is not blue, are there other things that are blue? What makes them blue that does not apply to the sky? If there are no things that are blue, then what's the point of having the word "blue", unless it is to describe things that look blue?

barfo

Most blue things are blue, except the sky, and bodies of water which are simply reflecting the sky.

 

[MARIS61]

And what would your 7th grade science teacher say about that answer?

barfo

Obvious.

 

[MARIS61]

Because Rudy might leave?

he's THAT important to the future of this franchise??

The Spanish Armada certainly was, and when Sergio left the downward spiral started. Then we lost both centers, probably permanently, traded the wrong PG and SF, and now we're just a clumsy hodgepodge of odds and ends now with no PG or C at all for the future core.

 

[GriLtCheeZ]

So what color is the sky?

 

[MARIS61]

Why are things the color they are?

[barfo]

Most blue things are blue, except the sky, and bodies of water which are simply reflecting the sky.

And by "are blue", what exactly do you mean?

barfo

 

[barfo]

Why are things the color they are?

The simple answer is, things appear a particular color because they reflect that wavelength of light. The sky, the ocean, and the blue car are all observed to be blue because they reflect the wavelength of light corresponding to blue more than they reflect other wavelengths.

The sky is blue for the same reason the car is blue and the water is blue. So if the sky isn't blue, neither is your (possibly hypothetical) car.

Water isn't blue due to the reflection from the sky. Visit an indoor swimming pool sometime.

Very, very sad.

If you read the link you'll see this is only true of some things, and not of sky. Sky refracts the light, while solids reflect or absorb. Liquids sometimes do both...or simply transmit.

As for indoor pools, they are painted blue and the water is (hopefully) clear.

Talk about a thread descending into the abyss...

And it had such promise for high intellectual discourse before I ruined it all.

 

[Minstrel]

If you read the link you'll see this is only true of some things, and not of sky. Sky refracts the light, while solids reflect or absorb. Liquids sometimes do both...or simply transmit.

And since colours are a perceptual experience, "appearing blue" and "is blue" are generally the same thing. There's no such thing as being "intrinsically blue." Something is/appears blue due to how it interacts with light, to our eyes.

 

[julius]

Are we seriously having a discussion about the 'color' of the sky?

Can't we just talk about how Sergio never improved his game enough to stay in the league, and didn't make a shit of difference?

 

[barfo]

Yes, if you want to build a case based on the difference between reflect and refract then I guess you can. But then you are just saying that air is gaseous and the car is a solid, nothing more profound than that. What determines the color is the wavelength of the photons that bounce off into your eyes.

As for indoor pools, they are painted blue and the water is (hopefully) clear.

Really? Every indoor pool is painted blue? And if you failed to paint one blue, the water would appear clear?

In any discussion of Sergio, it is critical to first establish the answer to "what color is the sky in your world?"

[MARIS61]

Let us open another can of worms:

Anyone here colorblind?

[The Professional Fan]

What difference does it make? Both discussions will go around and around and around and nothing will ever be agreed upon.

 

[barfo]

Beginning of 2nd paragraph says you are incorrect.

http://www.dartmouth.edu/~etrnsfer/water.htm

Not really. It's just two different uses of the word intrinsic.

Suppose our eyes functioned such that we could see in the UV spectrum. Would water still be blue? No, it would not. It would be, well, ultra-violet. Not to be confused with ultra-violence, droog.

But yes, water is intrinsically blue when considering our eyes and how we see the light interacting with it. Which contradicts, by the way, your claim about swimming pools and other bodies of water.

In the world of fandom opinions, perception is everything.

http://www.dartmouth.edu/~etrnsfer/water.htm

That sentence calls water "intrinsically blue" which obviously isn't the use of the word you or I are using (since you called water clear). Or do you now believe water is, in fact, blue?

By "intrinsic," I meant a quality independent of the perceptual measure used. Things look a certain colour to us due to how our eyes perceive light and how that light interacts with matter. That being the case, it's perfectly reasonable to call the sky blue or to call the ocean blue, because that's the colour we perceive when using our eyes to measure the light's interaction with the atmosphere or ocean.
