comment Klein–Gordon equation
In terms of the logical role it plays in QFT it is not true that the K-G equation is a relativistic version of the Schrodinger equation and the sooner you get this idea our of your head the better off you will be when you learn QFT.

comment Condensed matter application of AdS/CFT
You could view the connection between 3-d Chern-Simons theory and 2d WZW models as a toy version of AdS/CFT and it is certainly more well defined mathematically, but it doesn't capture a lot of the richness of the duality between N=4 SYM and IIB on AdS_5xS^5.

comment Condensed matter application of AdS/CFT
Eric, I think Matt Reece gave you a good answer. If I come up with a better one as I learn more I'll let you know.

comment Why do we define such a thing as singularity?
BTW, the singularity is not in the "middle" of the event horizon. An observer who passes through the horizon does not find the singularity at some particular spatial location, rather it is in their future. That's why they can't avoid it. It's like death and taxes.

comment Where is the Atiyah-Singer index theorem used in physics?
Thanks Eric. I gather this just got restarted. I hope it works. It has some ways to go before it is MO quality.
