New evidence that our world is two-dimentional.

Retweet from @bruces
It seems a new evidence found, that our universe is not 3d but 2d surface. According to Holographic principle in in string theory physic inside some volume of space could be completely described by the theory restricted to the boundary surface of that volume. That is tree-dimensional physical processes inside the volume of space could be seen as illusory projection of the two-dimensional processes on the surface of that volume. The new development here is that as in quantum theory space-time should be granulated, that granulation should be primarily two-dimensional, on the surface of the volume. The space-time granulation inside the volume would be projection of the surface granulation. And – here the news – that projected granulation should be bigger than original surface granulation(plank length). That bigger granulation should create additional blur, or noise in physical effects. And it seems that noise exactly like that was detected at GEO600 gravitation waves detector

Marker based augmented reality on CNN

Net is buzzing about CNN hologram at election night. What this tech really is the augmented reality + 3D imaging technology. CNN had 35 cameras in a ring at Obama headquarter to capture Jessica Yellin image from any possible 2D direction, with angle delta small enough not to be noticeable. After correct frame was picked up it was inserted into main videoframe. It seems to me the red circle on the floor was used for positioning of the image, as fiduciary marker. If you pay attention to the last part of the video you can see that Jessica “float” a little over the circle. That is because the circle is not the best choice for the marker. Square is probably the best fiduciary marker possible. It have distinctive corner, which could have subpixel accuracy, because they calculated as intersection of linearized square sides, and it produce third dimension axis easily, as cross product of cross products its sides.
