One of the greatest motivating forces for Donald Knuth when he began developing the original TeX system was to create something that allowed simple construction of mathematical formulae, while looking professional when printed. The fact that he succeeded was most probably why TeX and later on, LaTeX became so popular within the scientific community. Typesetting mathematics is one of LaTeX's greatest strengths.

Note that you do not need to have TeX installed, since matplotlib ships its own TeX expression parser, layout engine and fonts. Any text element can use math text. Regular text and mathtext can be interleaved within the same string. The mathtext font can be selected with the customization variable mathtext.
