Invisible paper clips! How do they work?

In the past, researchers have only been able to “cloak” microscopic objects using extremely complicated physics and so-called meta-materials made on a tiny scale.

But a new study at the University of Birmingham in the UK has taken a major step forward by making a paper clip invisible — an object thousands of times bigger than in previous experiments.

The research works by using a naturally forming crystal called calcite which has extraordinary light-bending abilities.

What’s not entirely clear to me, so to speak, is whether you have to have a crystal exactly the right size at exactly the right angle. The laws of physics will take some bending, but breaking them, I suspect, will require some serious quantum activity. Not that there’s anything wrong with that.

    The next step is invisible essays, which my students will hand in. Right now they are handing them in with invisible staples, apparently.

    On the other hand, if you can’t see the papers, you can’t mark them down for crappy design.

    Well, yeah, and it makes giving a zero a lot easier if you can’t actually see the thing. I mean, how would I know it was not plagiarized?

    I would have appreciate this “invisibility” cloak when using paper clips at my last job; the Partner #2(and, simultaneously, Spouse of Partner#1) declared usage of paper clips “wasteful” and was on a constant lookout and reprimand mode for any employee clipping samples of plastic laminate, carpet and paint with it.
    Needless to say, usage of binder clips was considered downright criminal.
