I will just mention that this guy doesn’t really look like Brian Greene. And that I’m disappointed the word “heterotic” couldn’t be worked in there somewhere.
And also that ordinary one-dimensional strings don’t form knots in higher dimensions of space, so extra-dimensional bondage requires extended objects. So really the guy in the cartoon should probably be “Dr. Polchinski.”
Cosmic Variance is a group blog by people who, coincidentally or not, all happen to be physicists and astrophysicists:
Our day (and night) jobs notwithstanding, the blog is about whatever we find interesting — science, to be sure, but also arts, politics, culture, technology, academia, and miscellaneous trivia. We have similar outlooks on many things, widely disparate opinions about others, and will do our best to keep the discourse reasonably elevated.

Strictly speaking, “ordinary” (as in, say, smooth or P. L.) strings don’t knot themselves in 3-space either.
Of course closed loops do, and yes, so do non-smooth (or non- polygonal ) strings and non-compact strings, etc.

Hmmm, I thought that this cartoon was just a rip-off of the excellent ‘hyper-bondage’ xkcd cartoon in the recent xkcd vs The New Yorker cartoon-off.

I don’t know what kind, but its got to be some kind of awesome when my favorite science feed mentions my favorite webcomic.

I am pretty sure I have never seen the real Dr Greene in a tie, either.

Mouse over the red button below the comic for more compactification-related excitement.

At least there was one for the chemists today.
I don’t think I’ve ever seen orbifolds used in humour before. Pity I can’t even wrap my head round differential geometry (dispite having passed the exam once …).
Linky, since Blake isn’t tooting his own horn for some reason.

He might not look like the real Brian Greene, but he definitely has an imaginary likeness.

That picture gives me a large hadron.
