Unfortunately, the images cannot be included in the comments at blogs run by blogger.com.
Also, I can't offer you LaTeXrender used by Peter Woit because this blog is not based on the software by WordPress. But it is likely that if I need some mathematical expressions that look really unacceptable in the ASCII format, I will be using Shital Shah's solution instead of the previous plugin.
I don't plan to increase the amount of LaTeX - in whatever format you can think of - on these pages. And I am jealous about the WordPress LaTeXrendering feature.
AlJazeera argues that only string theory has the right to destroy what God has created.

Moreover, don't forget that if you choose the Siegel gauge, every nontrivial string field theory amplitude contains as part of its expression
