Quantum entanglement and the Ryuki finale
I know, I'm overresearching things again, but given Kobayashi's penchant for physics in her shows, I had to go looking for Brian Greene's PBS report on quantum entanglement, or "spooky action at a distance." I was actually looking for the video (since I caught it on The Fabric of the Universe one day), but the article is still pretty easy to understand because Greene does a damn good job making it accessible. I think I may one day wind up writing Ryuki fics based off his stuff.
