At least the folks at Galactic Mu think we are, because we print a summation, New Take On Invisibility - 'Shrinking' Nanoparticles Visible Size Without Reducing Physical Dimensions, rather than just violating the copyright of the Advanced Materials folks and reprinting their whole article. Well, we do what we can. The topic is interesting because current metamaterials can't be made (yet) in the optical range due to the limits of nanotechnology, so this is an interesting waypoint. I think it is a waypoint, in much the same way that disk compression was a waypoint on the road to ginormous hard drives. A problem was solved while a really big problem took more time to be solved. Invisibility is cool. I will be first in line to buy one of these stealth battleships. Galactic Mu is a cool name too, because wavelengths always remind me of one of my top 5 favorite science pickup lines: "Enough about me, let's talk about mu."
