Since I never used math with ConTeXt, I tried to replicate XKCD 2034 as an exercise (see below and attached). I’d like to put it on the wiki and in my book. I know this is nonsense, but I’d like to do it right. In some cases I’m unsure which symbol the author meant, e.g. p or \rho, 0 or O, 1 or I or | ... Yes, I could have used proper Unicode characters (ρ, π etc.). Can you answer my questions (%? in the source)? (Partly TeX related, partly math/physics related.)
