Does anyone know how he writes his papers? His illustrations will forever be beyond my skills, but I’d like to up my paper mojo. Since his references are in bibtex, I assume he’s using some flavor of TeX, but this looks more sophisticated than LaTeX. In particular, he has small sub-illustrations next to his section headings that are really hard to get right using LaTeX. Is he using ConTeXt? Which fonts does he use? The ligatures are really nice, also hard to do using standard LaTeX available fonts.
