Experts create invisibility cloak
-
Very true...But still promising since visible light is just a different part of the spectrum. Also, if you wanted to be difficult, you could say that invisibility doesn't just apply to the spectrum perceived by human beings. J

Sure, we call things that we can't see "invisible", but that ignores all of those things that we can't see and other things can't see. For those, we need to make use of superlatives: "really really super extra invisible!" Or just scope it: "invisible to radar"

Yeah I saw that, although I'm not too sure how many people would see in the microwave spectrum so calling it an "invisibility" cloak is a little misleading.

however since all active radar systems work within the microwave spectrum, it is slightly better to call it a cloak of invisibility than the next top-secret military stealth skin.

we already have invisible objects, blue-bottom craft to fly in broad daylight, black bottom at night. The human eye is the easiest detection method to "fool" the human eye sees very little, and even that very poorly. We have irregular optical densities in our visible eye-tracking capability as well as non-uniform spaced sensor cells. "Invisible" to humans is called "easy" invisible to technology is a greater challenge.

Just a wild guess, but the unfortunate fact that this was developed in the white world, not the black one might have something to do with the latter moniker not fitting. :((

Actually, it could still be classified. If you invent something in the white world you know will benefit the black, you misdirect its capabilities give it cute names and hope you can get the attention before the subject is classified and the research removed from your care. Just because it is invented in the white world, and even announced does not make it safe from being classified.

Bad Astronomy |VCF|wxWidgets|WTLWhile they say it is hidden from microwaves, it is actually a narrow range of microwaves which is very dependent on the spacing between the metal elements used. Still really cool, especially the posibility of creating a perfect lens at a specific frequency.

My point was that even if our defence agencies grab the tech and bury the latest advancements in it, just knowing that it's possible is a major leg up for countries like russia, china, france, or germany that would want to copy or find a way to defeat the technology. If it was black from inception, until some idiot politician blabbed they'd have no idea we had another trick in our stealth arsenal at all.

Which is why some scientists have gotten in biiiig trouble for announcing something of this magnitude without first handing it over for government control. And these might still too. You won't get any recognition for your work if it goes black, so if you want that recognition, you do what was done here.

The other experts are working on that, too. :)

What’s wrong with France or Germany? You did know this technology was invented by a British scientist, didn't you? :-D

Well, the article says a "US-British team of researchers", but it does sound like some typically US-centric assumptions were being made by Americans. What's new? :^)
