As a Peace Corps volunteer in Nepal I had the privilege of teaching math in Nepali to students most of whom were unable to afford shoes. My first math lecture was with a stick in the dirt. Pythagoras would have fit right in, although the robe would have been a bit exotic. The school did not have running water, heat, or electricity; there were no blackboards. My students were eager and avid learners, who taught me that education always involves an exchange of information and it isn't delimited by tools, language, or resources -- it is bounded only by the curiosity of mind.
