My niece and nephew have kaleidoscope eyes. I didn't know what meant until I saw their eyes. Waaaaay cool. I've always gone bonkers for pale eyes with thick, dark rims around the irises. Justin's eyes are the best on earth. They're, like, cobalt blue or something and infinitely deep. They're luminous, too. I used to like bright eyes in general until I discovered a common thread of codeine.

What's race?

Congratulations on reaching the dream state! You're my hero.

It's a deep blue color, yes. No never had the cajones to get that close and gaze into his eyes........... but they are VERY dark from stage. My niece has the deep blue eyes too. Just super dark blue, very unusual. Only one in the family with them too.

Shall I suggest..."BLUE ONYX"? now that is as black of a blue that you may have...methinks

3+3=6

The ocean was a beautiful deep blue today coming home. Justin's eyes are a few shades darker, my grandbaby's are a few shades lighter, but on the same spectrum. It's mad Viking blood coming out........

All interesting concepts. Like, the color maroon isn't on the spectrum, because it's in between violet and and red. And you can't find that on the visible light spectrum. Therefore, since all things double back on themselves, maroon must correspond to all the light frequencies in between purple and red, GOING THE OTHER WAY AROUND THE SPECTRUM.

Then of course you have the last number in pi..... and I think Carl Sagan covered that rather nicely in *Contact*. I enjoyed the book and should read it again.

Too early for this, off to cook an omelet for brekkie. Promised to take my son and family to the hippy diner today, and darn it's getting COLD.... tempted to beg off.

I'm begging. Pretty please ask me to provide a pixellated analysis of your comments? Oh, please?

Oh, thank you. Here's my pixellation:

Newton's visible spectrum of white light is a continuum of monochromatic frequencies. Think of one electron making one transition between any two "energy levels." Maroon is made by at least two electrons making different transitions. So let's say you excite some hydrogen, you'll get some chartreuse lines from the Lyman series, some red from the Balmer, a little blue from the Paschen and Brackett series. Since the electrons are so small and there are so many of them, the colors add up to whatever color you see in a hydrogen discharge tube. De-exciting air is pink, at least it was when I was in college. I went to a party school.

On the subject, I see people are making fun of the greatest human physicist ever (next to Justin of course), Isaac Newton, for naming blue and indigo separately. That is so misguided. Of course you would want a separate category for the captivating royal blue frequencies and the mesmerizing ultramarines. I can go crazy just remembering my ultramarine wall.

Anyway, I can dig going the other way around a color wheel, but the spectrum is generally considered linear. So, you have me thinking about rainbows, and when I get a couple minutes of unfrazzled brain time, I would like to figure out why double-rainbows have their color reversed. Thanks for jogging that thing in my skull. Much appreciated.

Thirdly, not everything doubles back on itself. Consider my big gut combined with my bad back. This proof could be fatal.

lunazure said Then of course you have the last number in pi..... and I think Carl Sagan covered that rather nicely in *Contact*. I enjoyed the book and should read it again.

It doesn't have one, but if it had a final digit, I would suspect it falls somewhere between 0 and 9 inclusive. Now, arguing from the false premise that all things double back on themselves, it would necessarily be 3, right? Who knows. Maybe they do on the Left Coast.

lunazure said Too early for this, off to cook an omelet for brekkie. Promised to take my son and family to the hippy diner today, and darn it's getting COLD.... tempted to beg off.

I can neither prove, disprove, nor comprehend this hypothesis. It's above my pay grade.

lunazure said I'd have to look at the frequencies, but yeah indigo and blue should be two shades. I suspect they vibrate at different wavelengths.

I was trying to be funny, the delta-lamba's being way too small between the two to make sense with the rest of the progression, not to mention the absence of two blues on additive or subtractive color wheel schemes. The joke is I am crazy about blue. As I child, one of my earliest memories is hiding behind a chair in the living room staring at a blue LEGO with my mouth open trying to soak in all the color. Then, you should have seen me painting my wall ultramarine. It was to die for. I've since moved on to more and more intense frequencies as they years have passed. At least your suspicions are correct.

lunazure said Are you sure double rainbows reverse? I thought the same order of colors repeated in the smaller inside rainbow. Darn now I'm wondering! But what IS in between those two rainbows? What colors? What vibrations, and how does it manage to repeat? The spectrum, though of course thought of as linear, must be circular from apocryphal evidence. Do rainbows really shoot out gamma radiation???

I am not sure, but that is what appears to be the case. You may have two rainbows with the spectrum going the same way. That is caused because the sun's rays are being refracted through air masses with two different sizes of raindrops. That phenomenon is referred to as "twin rainbows" rather than "double rainbows."

If you cannot see them, there are no colors.

I am on a deadline tonight, so I cannot sort this out, but it appears that the secondary rainbows result from double internal reflection. Most light rays leave for the primary rainbow, but a few are internally reflected and refract out at the 53o-ish angle. A third internal reflection would give you a triple rainbow. I do not know enough about suspended raindrops to know if the multiplication of rainbows is caused by elongation or visibility.

This reminds me of a cool experience I had several years ago almost to the day. I remember because it happened on a birthday. (Present? Present?) I was taking my shower, and the sun was streaming through the window just right so I could see the suspended droplets in the steam. I told my landlords about it, as it was so cool. The landlady thought I was talking about some inner insight rather than a mere empirical observation. She also thought I was making a statement when I painted all the trim in my room black. The fact was, Lowe's was having a sale on white and black, and I chose one.

I have no idea what you mean by circularity, but back in the day when people observed spectra in mechanical spectroscopes, you could spin it in circles and repeat the scene. I loved spectroscopes. The colors were so pretty. I remember one element had beige in its spectrum. To this day, that freaks me out. One of my students one time decided to use diffraction gratings as glasses. That's really cool. You see the spectrum in three-dimensional cubes suspended in space.

Do rainbows shoot x-rays? I'd be more inclined to believe Jeff Wayne's spaceship shoots heat rays at the audience. For one thing, rainbows are light. How are visible frequencies supposed to shoot x-ray frequencies. This would require some new concept. I've heard of the "light as a projectile" theory, to which I do not subscribe; this would require something like a "light as an aircraft carrier" theory, which is -------- Next question?

lunazure said OK you have two books on your reading list now that tie into the premise. One is *Contact* by Carl Sagan (it's much better than the movie, even if he did crib a bit from AC Clarke). Basically the heroine goes looking for the final digit of pi. They didn't bring that out enough in the movie. Carl also took a swipe at organized religion, but nicely I thought.

My mind is so little, I need to spend more time learning basic engineering concepts, methinks. But thanks for thinking about me. Maybe I'll be in the right mood one day.

lunazure said and *The Day After Tomorrow* by Robert Heinlein. I think you'd really like this last one, because in addition to some really mind bending light spectrum and unified theory play, it addresses the concept of "what would happen if American were invaded?" Heinlein style. It was published originally as *Fifth Column* Once you read it, you'll understand why I usually put "Bokononist" in the slot reserved for religions.

I'm not a fan of Heinlein, but I adore a lot of people who are. Maybe I will stomach this one one day, too. Before then, I have to get my articles filed and read a couple books on the future of monetary policy for review. Talk about fiction!

Oh, well. I'll get off around 2:00 this morning. I need to find some time to sleep so I will be able to drive to a concert sometime. Shouldn't I?

lunazure said At this point, I'm just really happy my Internet came up again this morning. It went toes up at 1 am.

I was not clear. Think of internal reflection in terms of each individual raindrop for double rainbows. The air mass would not be between the bows rainbow for either a double or a twin rainbow. When we meet up in Arizona, we can get the Cheerios and I can model this stuff for you. I'll have a blast as you tap your foot, silently asking, "When can this be over?"

I haven't read Robert Gates, but I'll make a note of it.

Even laytah -

It's a date!

Incidentally, during the Moog tour yesterday, which was supposed to be for the little girls, the tour guide and I got off on this really geeky conversation, and I noticed the intended audience was looking around silently asking, "When can this be over?"
