Mathematica doing mathematical typesetting is news in the industry in about 1997. For practical comprehensive overview of typesetting as a field, see Wikipedia. You can see some examples of latest features added to its typesetting system here: http://www.wolfram.com/products/mathematica/newin7/content/EnhancedTypesett= ingAutomation/ for the programers here who likes to compare Mathematica as a programing lang, see: http://wolfram.com/products/mathematica/analysis/ Xah =E2=88=91 http://xahlee.org/ =E2=98=84
