Wave Cancelling not only allows for the power to cancel out external noise but now it can make you invisible! The ability to do this is done using Quantum Mechanics and electron properties. Researchers at the Imperial College of London have done all the hard work to make this possible.

The excerpt below is taken from http://www.royalsoc.ac.uk/exhibit.asp?id=4659&tip=1

Quote:
The secret to this breakthrough at Imperial College London is specially patterned crystals made up of nanoscale boxes that hold electrons. ‘Basically we have made ‘designer atoms'’, says Chris. ‘By choosing the size and shape of our little boxes, we can use the rules of quantum mechanics to choose the energy levels of the electrons that are trapped inside them’. When light is shone on these crystals it becomes entangled at a molecular level rather than being absorbed, causing the material to become transparent. ‘You can think of the effect as similar to the way that the peaks and troughs of water waves cancel each other out to create calm water’, explains Mark Frogley. ‘In the materials created it is the wave patterns of the electrons that cancel each other allowing light to travel through the material and making it transparent’. At the moment the effect can only be produced in a lab under specific conditions but future applications could include seeing through rubble at earthquake sites, or looking at parts of the body obscured by bone.



Wow that's pretty impressive but I wonder if it's harmless?

Awesome but it sucks at the same time. That means everyone can do it then. I wish we could only do it. Teee that would be fun!

Its certainly some remarkable progress but I found the royal societies presentation of the story a little sensationalist, as if we are only a few years from being able to pick up a invisibility cloak.

This puts things a little more realistically

It is only very small, special objects for a miniscule period of time. Facinating, but your not likely to see anyone vanish as they don a cloak anytime soon.

That's simply incredible. Thanks for the link pants. Wow, this is a step from those gimmicky "Project background onto raincoat" peices of crap.

I heard of this before in a mangaize, glade two people put up some more information about it.
