Scientists beam light around corners

A team of scientists have successfully bent light beams around objects on a two dimensional surface.

Its the first ever demonstration of what is known as "airy beams", with light being bent around an object and then course-correcting itself to continue in a straight line on the other side. The technology could open the door to faster and cheaper light-based computer chips.

"The international team, including three members from the Research School of Physics and Engineering at ANU, have successfully demonstrated that a tiny beam of light on a flat surface can be bent around an obstacle, and course-correct itself on the other side of that obstacle."

Mmm and this is a little different from refraction

oh I don't know! doesn't light bend naturally around objects anyway? Nope, not without huge gravitational assistance from nearby galaxies it doesn't.

they already have cloaking... military tech is always years in advance of what's shown to the public. http://www.youtube.com/watch?v=tT-jgBk5IJg skip to 3:30

Just look at the guys in the background, and the guys that run from left to right in another part. They have a similar distorting look with movement, but they're uniforms are darker.

Are you thinking objectively or just repeating what others said in the youtube comments? If that were the case why is he the ONLY soldier that appears that way(not to mention he comes from a totally random direction all alone)? If ... [More]

I notice they didn't say how they are creating the wave. These guys will be rich soon.
