Abstract

During the whole time that man exists on the Earth no human eye has ever seen the reverse side of the Moon. It is highly probable that at first the Moon had an axial rotation relative to the Earth but tidal friction has slowed this rotation down till the Moon remained for ever directed with one side towards the Earth.
