What's with the lightings?


I'm not 100% sure what you mean by your question, but as an amateur astronomer (and photographer) I'll take my best guess at what you're asking. Astronomers prefer red lenses in their flashlights for two reasons.

(1) Red flashlights have the least impact on your dark adaptation. It takes nearly an hour of complete darkness for your eyes to FULLY dilate to the point of maximum sensitivity. This dilation greatly enhances your ability to detect extremely faint objects such as galaxies and nebulae. One instant of white light will undo this effect. Red lenses have the least impact on your dark adaptation.

(2) Thanks to light pollution astronomers tend to gather in large groups in the few remaining places where we can actually see the sky. The plethora of red lenses is quite the spectacle. Especially in time lapse.

Hope that helped.

> No, he is actually correct. A hologram is a very specific thing.

No, an "Off-axis" hologram is a very specific thing. Those 1960s-type off-axis holograms require lasers both for recording and for reconstruction (playback.) Those are the very definition of "hologram."

But credit card holograms, rainbow holograms, are different. The spacing of the zoneplate fringes in Rainbow holograms doesn't play a part in creating the 3D image. It only creates the rainbow-colored artifact. Rainbow holograms can be viewed with incoherent white light. So, should we even be calling them by the name "hologram?" Well, they're certainly not photographs. They don't use interference for playback. Yet they still employ light-scattering by fringes in order to create a 3D scene.

The stunning fact is that Rainbow holograms are size-independent. Increase or decrease their fringe spacing, and they still function as holograms. Use randomized fringe spacing, and they still keep working. Or rather than hundreds of close-spaced fringes, use just one fringe per image-pixel. They still keep working! You can generate the fringes with a laser. Or you can scribe them with a needle. Or you can make giant "fringes" using curved, highly polished steel pipes.

I guess it can be painful to suddenly have to think outside the box; to realize that "holograms" are not exactly what everyone thought they were. I've found that many people are angered when someone suddenly goes and moves the limits encompassing a well known concept. But a rare few are delighted.

> Grr, it's not a hologram.

spoco2, go to the website and read FAQ entry 9 (links below)

These are Benton Rainbow Holograms where the spacing between fringes is wider than normal.

Rainbow holograms are based only on fringe angle and not fringe spacing. They are size-independent; that's why they reconstruct with incoherent white-light illumination. With Benton Holograms, the distance between fringes is irrelevant. With Benton Holograms, the fringes can be drawn by hand. Apparently nobody realized this until I saw the phenomenon occurring naturally when someone polished a car hood with a gritty cloth.

> Holograms are a recording of light from other objects such that

So you're saying that Computer Generated holograms aren't holograms, since their zoneplates are drawn by computer? Really? If CG holograms are holograms, then so are mine.

> These are not holograms.

If you knew how those Rainbow Holograms on credit cards actually worked, perhaps you'd be angry when people called them by the name "hologram." If my Hand Drawn holograms aren't real holograms, then Rainbow holograms aren't real holograms either.

I have a close-hand magician good friend, and he showed me exactly how to do this. It's the same way magicians make rings, coins, and necklaces float.
It's an extremely thin wire, invisible much like fishing line but much much thinner, and also taut. The line is so thin, any movement such as breathing, can make it shake.
It's stuck to his jacket. And also the paper.
If you notice he never moves his hand between the paper and his chest. He only moves it above, below, and away from the paper. Never between his chest and the paper.

The paper is flash paper. The rose at the end is in his sleeve. The flash paper gives off a big white light, while he zips the rose out of his sleeve.
Pretty neat!


WOW, and here all along I thought it was real magic. Thanks for ruining my life.

Jesus, this track balls-out rocks! Wish I could vote twice. And promote. This track is actually one of several recorded after initial sessions from the 2004 album 'White Light Rock'n Roll Review,' on the recommendation of label representatives to fill out the album with a few more 'radio-friendly' tunes. This is definitely NOT filler material! The indignation in his voice is righteous.

(Is it just the light from the camera or something?)


I think it's filmed at night, with a very bright white light source, and is being affected by the video camera's auto colour balance.
His hand looks much more normal in the still photos in the link that xxovercastxx provided above.

Its true that being obsessive is normal, checking 6 times that you have your passport before travelling abroad is perfectly normal.

I personally have seen myself a little more obsessive than the norm, I tend to pick up bits of tissue off the ground, check that I have things about five times, the worst being when you check, and then you check again to make sure that you checking didn't lose it.

Nice use of White light at the end, made a change from he piano piece which i thought would never stop.

There are certain songs that were written to have these messages.. but not these suicidal messages.

Pink Floyd songs, Eminem(hi my name is), Gorillaz Song (white Light) - cant prove it, but I would expect it with the bands back story(Murdoc is a satanist).

There are many songs that have these things, but the listener still has to figure out the message, so the message is relative, and subjective to the listener.

Light therapy alone does not re-set your circadian rhythms. Light therapy combined with sleep (which the above video does not include) are the only effective ways to help re-set your internal clock.

You can't just point white light at yourself and suddenly be re-energized.

But yes, I want this in my house.

She's missing the middle of the song:

And as we wind on down the road
Our shadows taller than our soul
There walks a lady we all know
Who shines white light and wants to show
How everything still turns to gold
And if you listen very hard
The tune will come to you at last
When all are one and one is all
To be a rock and not to roll
Woe oh oh oh oh oh
And she's buying a stairway to heaven

You can change under your system background color under your general account settings. Even just setting it to a slightly off white light blues helps tremendously.

In reply to this comment by MINK:
(i could mention the white background on the Sift is very annoying but... maybe later)

alright, point taken... but if we put that bright white light on all videos then we will need to start yanking 9/11 videos and so on.

We could guilt-trip them into coming back to take care of their child??? Auction their collective after a month of inattention? Spam them with e-mails?? I like the 3rd suggestion.
I was once told when I first joined the sift, and noticed the usual, rabid counterpoint to anything remotely conservative, that going up against this type was like "knocking over chess pieces with a water pik" I chuckled at and appreciated the simile, and found this to be an adequate observation when applied to the dynamic between the faithful and faithless, (with regard to spirituality)....I like to look at it this way-
Those most rabid in their derision of religion, (and so-flagged, "conspiracy theories"), are invariably the folks with the most lop-sided, un-actualized and sophomoric world views. They tend to be insect-type personalities, who are satisfied being bound to the available sensory apparati, and have no room in their process for the unexplainable or metagnostic, unless that unknown factor is part of some scientific method or on-going codification or experimentation. This has everthing to do with imprint, experience, and exposure, and most of them will probably say, "Thank Bob, I was not imprinted with, or exposed to that, etc, etc, blahppity, blah blah, so many variations on a theme.

I propose a collective that encompasses the best of both worlds, the mundane and the supernatural. A pit, where the the zealots of both camps can preach, pontificate, and perhaps, proseletyze in.....call it, hell, God Vs.Satan, Black Vs. White, Light Vs. Dark...........

As long as the world spins there will be those bound to duality, meditating upon the differences of a single thing
kicking a horse without legs, trying to get the thing to move.......

You Christains can be preachy, lemme say, but those damn God-boppers must have some secret seminary somewhere as well....lioke I have suggested in the past, "Oh ye that have all the answers"....G E T A R O O M !!!!!
