Scientists say they're closer to invisibility cloak

THE ASSOCIATED PRESS
WASHINGTON–Scientists say they are a step closer to developing materials that could render people and objects invisible.
Researchers have demonstrated for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects.
Previously, they only have been able to cloak very thin two-dimensional objects.
The findings, by scientists at the University of California, Berkeley, led by Xiang Zhang, are to be released later this week in the journals Nature and Science.
The new work moves scientists a step closer to hiding people and objects from visible light, which could have broad applications, including military ones.
People can see objects because they scatter the light that strikes them, reflecting some of it back to the eye.
Cloaking uses materials, known as metamaterials, to deflect radar, light or other waves around an object, like water flowing around a smooth rock in a stream.
Metamaterials are mixtures of metal and circuit board materials such as ceramic, Teflon or fibrecomposite. They are designed to bend visible light in a way ordinary materials don't.
Scientists are trying to use them to bend light around objects so they don't create reflections or shadows.
It differs from stealth technology, which does not make an aircraft invisible but reduces the cross-section available to radar, making it hard to track.
The research was funded in part by the U.S. Army Research Office and the National Science Foundation's Nano-Scale Science and Engineering Center.
"Previously, they only have been able to cloak very thin two-dimensional objects."
How can you have a two dimensional object???

That's just a heisenberg compensator and maybe a new source of energy away. Get off your own ass and make it, you lazy bastard.

How can you have a two dimensional object???
wouldn't a "very thin" 2D object essentially be a line and almost invisible anyway? maybe they mean very thin 3D objects that could be considered 2D like a piece of paper...

By definition, a 2D object doesn't have a thickness - that's the 3rd dimension. That quote is fucked, lol.

Superman was kinda bored so he just started flying around looking for something to do. He's flying over Wonder Woman's house and sees her bedroom window is open. He stops for a glimpse and sees her lying on her bed naked. She's lying there and squirming around looking real hot.
Superman was getting turned on looking at her so he decides what the hell, I can just fly in real quick, give her the ole' in-out and be out of there before she even knows what hit her. After all he is Superman. So, in he goes, wham-bam and he's out of there.
Wonder Woman knew something happened and says, "What was that?" The invisible man says, "I don't know but, damn, is my ass sore." [/REALLYOLDJOKE]
