Most text-books on Astronomy state that the sun is a middle-sized star. This may be true when one compares it to the relative sizes of super-giants and white dwarfs. But how does the sun compare with the majority of stars? To answer this, I decided to calculate the stellar luminosity function as well as I could, using only the limited facilities at my disposal, that is, a slide rule and the Observers' Handbook.
