Textbook Question
Chapter S1, Problem 22EAP
Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer. (Hint: For statements that involve coordinates—such as altitude, longitude, or declination—check whether the correct coordinates are used for the situation. For example, it does not make sense to describe a location on Earth by an altitude, because altitude only describes positions of objects in the local sky.)
22. My UT clock had stopped, but I found find my longitude by measuring the altitudes of 14 stars in my local sky.
