From Woit's BLOG "Knots and Quantum Theory"

Japanese version
In October 28, 2011 E.Witten gave the lecture for general "Knot and Quantum Theory." Although backgrounds are Khovanov homology and quantum field theory, the talk included Langlands crrespondence (in usual in Number Theory), and they have taken the attention by some BLOG, which he might think in mind on the relations between physics and number theory. I complete to translate almost of Woit's BLOG with comments into Japanese and post it. The argument still continues.
