The Blackest Material
QuantumCrypto writes "Researchers at Rensselaer Polytechnic Institute have created 'the world's first material that reflects virtually no light.' This anti-reflection technology is based on nanomaterial and could lead to the development of more efficient solar cells, brighter LEDs, and 'smarter' light sources. In theory, if a room were to be coated with this material, switching on the lights would only illuminate the items in the room and not the walls, giving a sense of floating free in infinite space."

I think you mean Dolemite, not dolomite.
That is not dead which can eternal lie,
And with strange aeons even death may die.
this is a faulty assumption ... I'll leave the "virtually" out to simplify the statements, but here you go ...
...
... material clearer than glass but not quite as clear as air.
to say something "reflects no light" does not mean it "absorbs all light"
you are leaving out transmission of light. If a material does not reflect light, it either absorbs or transmits all the rest of the light.
which is actually what this article is talking about
this was quite an errant post as it is both a dupe and factually flawed.
That even a previous article about the stuff failed to be seen by /. editors.
Love many, trust a few, do harm to none.
Wavelength is pretty much the determining factor in hw EM radiation interacts with matter. Visible light is 400-700 nanometers, whereas radar is in the range of 1-40 centimeters.
If a job's not worth doing, it's not worth doing right.
Maybe not, but they're both electromagnetic waves (though with a very different wavelength). So the question may be relevant. It's not particularly relevant. The wavelength difference between radar and light is in the range of 20000 to one. You need two different antennas to pick up AM and FM, and they are only different by about two orders of magnitude (100:1). Dealing with electromagnetic radiation has everything to do with wavelength. A material "tuned" to absorb the maximum about of EM radiation between 400 and 700 nanometers wavelength is utterly unsuited to the task of absorbing radar at 1-4 centimeters. I'm not trying to be a troll here. I'm pointing out the science.
If a job's not worth doing, it's not worth doing right.
no, as a highschool student we have both goth and emo. The difference is goths are just like the same, goths havent changed, emo's on the other hand, are all about being pansy ass little pussies about everything and trying as hard as possible to look and act like emaciated little girls. Also the music is completely different, you cant even compair The Cruxshadows(really good band) to emo shit like falloutboy, panic at the disco, and the other "i hate my life and no one loves me bands"

Dude, do it with a little style.
Dupe: Reflectivity Reaches a New Low
if you're talking about the key color spilling into the subject (like in between hair and such) than that's a different issue. that's why when you do a telecine, you'll do what's called a "suppress pass" which desaturated all of the key's color. that way you can comp the original footage minus the key color back into the comp to kill the color spill without having to hand-draw it into each frame.
i'm sure it could be used for some pretty interesting techniques in photography and film but color keying isn't likely to be one of them.
