Scientific paper

As I have refined my conceptual astronomy course, I have been struck by the major confusion exhibited by students on the topic of angles. People intuit that smaller angular size means greater distance, but rarely apply this knowledge to actual events, in part because they cannot easily measure angles. To assist in naked-eye observations, I devised a simple and inexpensive device to measure small angles.
