Japan is long like a string though tiny. I think it cannot be compactified. Perhaps, the edge from the edge of Japan is further than Moscow from Prague. Fukushima now turns to be more popular than Tokyo in the world. Why? Earth quake, Tsunami, and Accident of nuclear…<br /><br />I have enjoyed your blog since about 2004. Recently, a lot of people enjoy the articles by Mr. Phil Gibbs (your guest) “Four reasons why I like string theory,” that I had translated into Japanese. What does the example of frogs mean? Please give my best regards to Mr. Phil Gibbs.<br /><br />And "Rumor of Higgs" is rather popular. But at once I neglected it with some reasons on my BLOG.<br /><br />Of course, your article on monstrous symmetry of Black Holes in 3 D is very interesting . Where modularity come from? Witten’s paper points out the mysterious relation between B.H. and monstrous symmetry via moduli of elliptic curves. Is it a new idea? Yes, but a pioneer is “Beauty and The Beast.” On your paper arXiv:gr-qc/0212096v3 Immirzi parameter is argued in this context. Interesting!<br /><br />I hope that the story of the gravity of 3D might be connected with “5-branes and Khovanov homology.”<br /><br />My best regards.<br /><br />Ken YokoyamaKen Yokoyamahttps://www.blogger.com/profile/05236785937528140451noreply@blogger.comtag:blogger.com,1999:blog-4352371825685007367.post-15043929481248756232011-05-26T11:36:13.841+09:002011-05-26T11:36:13.841+09:00On "reference frame" said:

So I have finally learned Japanese today and translated the article to the Fukushima dialect of Japanese. Enjoy and don't get discouraged by the obscene words on the first line beneath the title! ;-)<br /><br />Via K.N.
