:Interesting. I hadn't thought of that. Ttraditionally, ''H'' is used for the entropy function in coding theory. I'm not sure about the history behind that, but now that I think back to my physics classes, you are right about ''S'' being entropy. [[User:Greg Woodhouse|Greg Woodhouse]] 20:38, 4 July 2007 (CDT)

question

H is the science symbol for entthalpy, S the symbol for entropy. I think this H should in reality be an S, as that is the way it is in my books for prob. distribs. Unless it changed within the last year I think it still remains the S. I can even understand using A, F or G but not H, according to the universal definition of entropy it is unitless.
