A Step Towards an Invisibility Cloak

Posted by kdawson on from the who-goes-there dept.

An anonymous reader alerts us to work out of Purdue University in Indiana, where researchers have produced a design for a method of cloaking objects of any shape and size at a single wavelength of visible light. The math for such an invisibility effect was worked out last year at Duke and in the UK, but the new work, to be published in Nature Photonics this month, is the first practical design. The lead researcher, Vladimir Shalaev, notes that even though the current design works only at a single wavelength, and so would not convey true invisibility, it could still be useful — against, for example, night-vision goggles or laser target designators. Shalaev calls the technical challenge of producing an all-wavelengths cloak "doable in principle."

    Don't ever post any variation of this bullshit again.

    It was bad enough resorting to Digg et al on April 1st just not to be wholly uninformed.
    (Note: Planning a worm/virus launch? Your sysadmin's newsfeeds will be full of shit on April 1st).
    Thing is, it's over a week since I killed time on Digg because of ./the1st. That's when I saw it on Digg, and even then I thought "This was on slashdot months ago, and it was old news back then."

    kalidasa (577403) -- a racist bigot -- wrote, "So, apparently you assume that anyone without a European name is not a citizen - or, at least, anyone with an Indian name is not a citizen."

    The grandparent post made no such suggestion or implication. In fact, the GP did not even suggest banning Indian students; she simply raised a question.

    Kalidasa is attempting to silence discussion. His bigotted strategy is similar to the strategy used by Indian bigots. If you state that you oppose illegal immigration, then the Indian bigots immediately equate that statement with being racist against Mexicans or Indians. In this way, bigots like Kalidasa shutdown discussion. Once they succeed in equating racism with opposition to illegal immigration, then you are forced to shut up. If you continued verbally opposing illegal immigration, then you would be wrongly tagged as a racist.

    Kalidasa is a racist bigot. No doubt about that.
