I am just reading an article by Keith Waters (SIGGRAPH87) about facial animation here: http://www.cc.gatech.edu/dvfx/readings/waters-s87.pdf On page 20 (the 4th page of the pdf file) there is something that starts with x'' and then a strange symbol and the f(K.A.R.x). I guess the dots is multiplications, but what is that strange symbol that looks like the infinity symbol but with the right end cut off? And what does it mean?

I didn't look at the paper, because I'm pretty lazy, but the infinity symbol with the right curve cut off means "proportional to", meaning that the left side is equal to the right side times a constant multiple.

EDIT: For some odd reason, I can't view the paper. gv doesn't seem to like it, but I'm still pretty sure that I'm right on the math symbol.

Also used for expressing the significance level you''re testing for in a stats problem (hypothesis testing).

It seems that they don''t work with IE. In Mozilla they appear correctly.

I don''t think it''s an alpha character - isn''t it a special symbol (that kinda looks like an alpha) that means directly portional to?
