We learnt that the word “moon” is connected with words for to measure, reflecting the fact that from earliest times the Moon’s phases have been used as a calendar.  The moon illusion when the moon is near the horizon is well known, and it seems that it’s perceived especially by children.  We heard about the startling difference between the near and far sides of the Moon and possible reasons for this, as well as a hypothesis that the Moon’s tidal lock, which dictates that we always see the same side, may have occurred not over millions of years, but in the course of a single year.
