At many institutions these courses are the raison d’etre for the astronomy program, and at most other institutions they are viewed as an important term in calculating an astronomy department’s contribution.I have often had a sense that what we are doing in these courses is counter-productive to any serious understanding of the goals of liberal arts curriculum. Over the last six or seven years, as I have been participating in my college’s efforts to introduce a year-long, interdisciplinary survey of the humanities into our curriculum, this hunch has been confirmed: in our efforts to fit astronomy into the liberal-arts curriculum, we have ironically been undermining the enterprise.

While able to accurately correct for contaminating starlight, the overall photometric utility of the photometer is limited by night ...
