Invisibility Cloaks in Fiction and Fact

                                Good Day World!

Have you ever read the novel, The Invisible Man?

The reason I ask is because what was once science fiction is now fact.

Did you know that physicists have figured out the optical parameters for a magic trick they characterize as a kind of "invisibility cloak?"

Invisibility cloaks have been getting a lot of press over the years.

That's not only because Harry Potter put his fictional cloak to such good use, but also because researchers have been using high-tech metamaterials to create structures capable of bending light around an object to keep it hidden.

Physics professor John Howell and graduate student Joseph Choi are co-authors of a paper about the "Rochester Cloak" that has been submitted to the journal Optics Express.

Oh, yeah.

And there’s a lot of other invisible applications currently in use by our military. Like this one for instance. Here’s another one you should check out invisibility camo uniforms for our soldiers!

Time for me to walk on down the road…
