1 Introduction
For the last few years, I have taught a class called "Heavenly Mathematics & Cul-
tural Astronomy" [3]. The first part of the course covers basic positional astron-
omy, focusing on what the Sun, the Moon and the stars look like from different
parts of the world. Many astronomy books take a "high-latitude centric" point of
view, but I try to be "hemispherically correct" and consider the points of views of
observers in the Northern Hemisphere, the Southern Hemisphere and the tropics.
The rest of the course is dedicated to applications of these ideas with a cultural
flavor, like calendars [2] and navigation. In this article I will give some samples
from the first part of the course.
