#2Neat-o. A little bit more info at https://en.wikipedia.org/wiki/Two-photon_physics . Basically two photons with enough energy to interact via virtual pairs created.
It will be interesting to see the cross-section rates and maybe hopefully some new physics (as the wikipedia page weakly hints).

#3The bit about the trigger was interesting. Is that software/firmware? Or is that a hardware trigger they are discussing.

I think at the moment they use a level 1 hardware trigger and a level 2 software trigger. ALICE is moving to a pure software trigger.

As far as I know, nowadays there is a lot of high speed FPGA processing involved, therefore the line between software and hardware is blurred.

#7One step closer to holograms.

Not sure you'd want some high energy photons scattering on your face after the collision of the light sabers. Except if you want to call it "the photon menace".

#9One step closer to holograms.
Could you explain?
Also, do you not think that current implementations that use eye tracking are not real holograms?
What's to say that holograms similar to those of Star Wars could not be produced by inspecting the environment and automatically determining where people's head and eyes are, e.g. via a combination of technologies similar to the following:
Eye-tracking holographic table requiring 3D glasses: http://www.euclideonholographics.com/
3D TV not requiring special glasses for the 3D effect: http://www.ultra-d.com/
And what about things that have been called and accepted as holographs created since the mid-20th century?
