As an occupation, I'm a mathematical physicist, studying string theory and quantum field theory.

I've developed as a hobby a few Cocoa (Touch) apps. The largest one so far is spires.app, which manages articles and metadata downloaded from the arXiv eprint server, the inspire database, and the journal websites.

I'm also interested in many other things, which is why I ask questions in various StackExchange sites ...

comment How can I replicate affine Dynkin diagrams in Kac's textbook?
I guess when Kac's book was written pgf/TikZ was not available; shouldn't there be an elementary way? I like the way Kac used the standard arrows which is part of math fonts, not the generated arrows in XyPic or pgf. The triple arrow comes with AMSTeX, it's called \Lleftarrow and \Rrightarrow.

Sorry for looking like a dupe, but I really want to reproduce the Table in this textbook: books.google.co.jp/…
