Your comment about your pal just reminded me of "The Integral Principles of the Structural Dynamics of Flow", an fictional technical book used as a plot device in the Patriot TV series.

They even created a one season podcast read by the fictional author, Leslie G Claret, who's played by the actor Kurtwood Smith.
Does your pal really work as a chemical engineer ;)
