Young U. Ryu from the Department of Mathematics, University of Texas at Dallas developed Type 1 fonts for use in mathematical texts set in TEX, in 2000. It was based on Adobe Times and Helvetica, the TX fonts. His PX fonts are type 1 fonts based on Adobe Palatino, URW Palladium and Adobe Helvetica for doing mathematics. After some modications by Thomas Esser in 2002, more recent versions of the TX fonts and PX fonts were placed on the CTAN archives. In the documentation, Young adresses the design of mathematical symbols: The Adobe Times fonts are thicker than the CM fonts. Designing math fonts for Times based on the rule thickness of Times =, , + , / , < , etc. would result in too thick math symbols, in my opinion. In the TX fonts, these glyphs are thinner than those of original Times fonts. That is, the rule thickness of these glyphs is around 85% of that of the Times fonts, but still thicker than that of the CM fonts. He contributed these ranges to the GNU Freefont project: Arrows (U+2190-U+21FF), Mathematical Symbols (U+2200-U+22FF).
