Given exactly 360° in a circle and 365.24 days in a year, how many degrees per day does one's view of the night sky shift? (This assumes one looks in exactly the same direction, at the meridian - the middle of the sky defined by a line across it running due north to due south, at exactly the same time each night.)
If your plane has landed at some unfamiliar place on Earth at noon on March 21st, and you realize that the Sun is high in the sky, practically straight above your head, what does this tell about your latitude? Where geographically could this location be?
